                   the performance, service life, and reliability requirements of the manufacturer and as
                   specified in the Verizon contract.

            B.     In addition to selecting the appropriate equipment that fulfills the requirements of the
                   Order, the Detail Engineer shall choose and assign equipment options, etc., necessary
                   to fulfill the equipment requirements as outlined in the Order. The Detail Engineer shall
                   also verify that any options listed in the Order are correct and necessary for the proper
                   functioning of the equipment ordered.

            C.     In general, relay racks, frameworks and cabinets shall conform to existing frame types,
                   heights, widths, seismic considerations, and environmental requirements to the
                   specifications of the COE Engineer.

            D.     Communications panels shall be added in all transport aisles if local communications
                   are not provided. If three frames are added in the initial lineup, the panel should be
                   added in the third bay and every fifth bay thereafter on one side of the aisle. If only
                   one bay is added in the initial lineup, the panel shall be placed in the first bay and every
                   fifth bay thereafter on one side of the aisle. Remote handset / headset jacks extended
                   from the first panel may be used in lieu of subsequent panels within an aisle.

            E.     Miscellaneous equipment mountings and shelves shall be engineered to support
                   equipment in an adequate manner. The mountings must also allow suitable ventilation
                   for normal operation of equipment. Mountings and shelves provided by manufacturers
                   as part of standard equipment arrangements can be assumed to meet these
                   requirements.

      2.2   Equipment Layout Requirements

            A.     The environmental requirements of equipment to be installed shall meet or exceed the

                   specified by system framework assembly drawings and/or different ground planes.

            B.     Frameworks, which are rigidly bolted to adjacent frames at both uprights with 3 steel
                   junction plates on each upright (one at top, one center and one at the bottom) require 1
                   top support and 2 floor anchors. Isolated frameworks (frameworks not rigidly bolted at
                   both uprights or any end framework) require 2 top supports and 4 floor supports.

            C.     If a framework cannot be rigidly bolted to adjacent frames because the frame uprights
                   do not line up, the frame shall be treated as an isolated frame.

            D.     Zone 4 rated frames are not a requirement throughout the entire Verizon footprint for
                   non Rack & Stack configurations. Non Rack & Stack frames should be rated for the
                   zone in which they will be deployed

            E.     Floor anchors in a lineup of frames rigidly bolted together shall be installed with four
                   anchors on the end frames and two anchors in a staggered pattern in intermediate
                   frames.

            F.     In Seismic Zones 3 & 4, four anchors are required for all frames. Refer to GR-1275-
                   CORE, Section 11.3.3 for further information.

3.    CROSS CONNECT SYSTEMS

      3.1   General

            A.     Cross-connect systems consist of distributing and interconnecting frames. These
                   systems are used for cross-connection, electrical protection, test access, temporary
                   disconnection, and facility termination.

            B.     The following Telcordia publications relate to the fundamental generic requirements
                   for metallic interconnecting of digital products:

                          Telcordia Transport System Generic Requirements - GR-499-CORE
                          Telcordia GR-1502, Section 3

            C.     Verizon will specify the specific requirements for new cross-connect systems in the
                   Order. Cross-connect frames should not be placed in line with columns.

            D.     Existing cross connect equipment, such as distributing frames, shall be engineered for
                   expansion by the Detail Engineer. In most cases, existing frames will be engineered for
                   growth by the addition of similar terminal blocks and structural details. All cable
                   termination assignments on cross-connect frames shall be recorded on assignment
                   drawings and maintained by Verizon Engineer. The assignment of all termination
                   blocks and added apparatus, if not specified in the Order, must be assigned by the
                   Detail Engineer.

      3.2   Zoning and Spread

            A.     All equipment terminated on a Distributing Frame (DF) shall be zoned and spread.
                   Zoning is defined as reserving a certain area for specific equipment. Spreading is
                   defined as insuring the placement of equipment in several locations on the frame.

            B.     Termination on Verizon Cross Connect frames shall be made in accordance with any
                   frame masks maintained by the Verizon Engineer or Common Systems Engineer
                   Planner.

      3.3   Conventional Distributing Frame

            A.     The horizontal side of the Conventional Distributing Frame shall be used for line
                   equipment, special services and miscellaneous and or transport equipment terminations.

            B.     The vertical side of the Conventional Distributing Frame shall be used for Outside
                   Plant (OSP) cable, derived Digital Loop Carrier (DLC) pairs, tie cable and certain
                   special services equipment.

            C.     Distributing Frames shall be added or extended only at the direction of the Verizon
                   Engineer. When existing distributing frames are extended, the extension shall conform
                   to the existing physical type and size, unless otherwise directed in the Order.

      3.4   Manual Digital Signal Cross-Connect (DSX) Lineups

            A.     DSX frames shall be designed as an entire system of supporting framework (relay
                   racks), vertical and horizontal routing guides for jumpers, cable management/support
                   for interconnecting cables, cross-aisle ties and inter-bay patch panels. System design
                   criteria shall be specified by the DSX manufacturer. Under no circumstances shall
                   DSX panels be engineered or installed in frames not designed for the purpose. Refer to
                   GR-320-CORE “Fundamental Generic Requirements for Metallic Digital Signal Cross-
                   Connect Systems DSX-1, -1C, -2, -3”.

            B.     Interconnect Frames: Interconnect frames are similar in application to DSX frames –
                   except they do not provide cross-connect capabilities. They are used primarily to
                   provide an access point between two interconnected Network Elements, two
                   interconnected Cross-Connect frames or between a Network Element and a Cross-
                   Connect frame. Interconnect Frames shall only be used or established or at the
                   direction of the Verizon Engineer.

            C.     Digital Cable Size and Equal Level Point Considerations

                   1.     The cabling of intra office electrical digital signals must be engineered to
                          standardized digital interfaces that are better defined as Equal Level Points. An
                          Equal Level Point is defined as an access point in the network interconnection
                          where all circuits fall within a specified signal strength and standard format.
                          DSX frames and interconnect frames are considered equal level points.

                   2.     Line Build Outs (LBO) (devices used with each piece of digital equipment to
                          cause the output signal at the out jack of the DSX to fit the prescribed template)
                          will be used to introduce the attenuation and pre-distortion of the signal to
                          simulate the effect of a given length and type of cable. The Detail Engineer must
                          ensure that cables terminating on DSX frames are matched with appropriate
                          LBO's, to adhere to the transmission requirements set forth in GR-320-CORE, as
                          well as those specified by the OEM.

      3.5   Electronic Digital Cross-Connect (DCS) Systems

            A.     The DCS system is the electronic version of the manual DSX and requires programmed
                   in messaging to enable a connection path.

            B.     Terminations shall be made on Broadband, Narrowband and Wideband as directed by
                   the Verizon cross-connect planner or as specified in the order. DCS terminations may
                   be made directly to the DCS, via a DSX frame or via an Interconnect frame. The Detail
                   Engineer shall follow the methodology prescribed in the order or as established in the
                   office cross-connect plan.

      3.6   Modular (Cosmic) Distributing Frames

            A.     Verizon utilizes computer-generated assignments for COSMIC distributing frames.
                   The Detail Engineer shall obtain such assignments from the appropriate system for the
                   office when COSMIC terminations are required.

            B.     The Detail Engineer shall also ensure that the new assignment report / drawing and pre-
                   printed frame labels are provided with the job specification.

      3.7   Fiber Distribution Frames (FDF’s)

            A.     Fiber Distributing Frames (FDF) - Optical cross connects shall be employed through
                   the use of FDF. FDF shall be deployed in all Verizon Central Offices, Controlled
                   Environmental Vaults (CEV) and electronic equipment enclosures. Cross-connect
                   lineups should not be placed in line with columns. Refer to Verizon 2004-045-COE
                   “Fiber Distribution Frame (FDF) Engineering Guidelines” and Telcordia Generic
                   Requirements and Design Consideration for Fiber Distributing Frames GR-449-CORE.

            B.     Field connectorized building cables or pre-connectorized building cables shall be
                   spliced to the outside plant (OSP) cables at the Cable Entrance Facility (CEF) or cable
                   vault; no splicing shall be performed at the FDF since this operation seriously
                   reduces termination capacity. If it is determined that optical fiber splicing cannot be
                   accomplished in the cable vault or CEF, an alternative splicing area, or optical cable
                   rearrangement facility (OCRF), must be provided in the central office between the vault
                   or CEF and the FDF.

            C.     The FDF configuration shall follow standards found under Verizon Interconnect
                   Drawings, COEI Bulletins, Engineering & Planning Support Flashes, New Services
                   Technology Support Guidelines, etc. In the event of a specific standard not found, the
                   Verizon Engineer shall be contacted.

            D.     A cross-connect configuration will be used and the FDF frames located adjacent to one
                   another to facilitate inter-bay cross connections. Space must be reserved during initial
                   installation at the top of each bay for tie cables to facilitate multiple line-ups and
                   possible future growth. Floor space shall be allocated for a single centralized FDF
                   system to terminate all fiber cables.

            E.     The FDF shall be located in an area that provides the easiest access from the CEF or
                   cable vault. This generally means an area near the existing main distributing frame
                   (MDF). Since the fiber optic equipment is usually not located nearby, this location may
                   not be ideal from an equipment-cabling standpoint. Of more concern however, is the
                   fact that there is usually not enough space for the operation and growth of both frames.
                   The FDF must not be inhibited from growing to its ultimate size. Some objectives of a
                   good FDF location should include accessibility, dedicated fiber protection cable
                   pathways and minimizing the length of OSP fiber cabling within the equipment area.
                   Of equal importance is the selection of the OSP splicing area. The cable vault or CEF
                   will be the first locations considered unless they prove unsatisfactory. An alternate
                   splicing area must then be established in the central office since splicing will not be
                   performed on the FDF.

      3.8   Subscriber Digital Distributing Frames (SDDF’s)

            A.     SDDF shall only be established at the direction of the Verizon common systems
                   planner or as specified in the Order.

            B.     Shielded jumper wires shall be used for all jumpers running on the SDDF. Shielded tie
                   pair cable is also required between frames when the SDDF is not part of the main
                   frame.

      3.9   Terminal Strips / Connecting Blocks

            A.     The standard Terminal Strip / Connecting Block deployed on conventional frames is
                   the wire wrap pin type.

            B.     Terminal Strips / Connecting Blocks shall be provided in accordance with the standard
                   type deployed in the Central Office unless otherwise directed by the order or unless
                   superseded by a subsequent Verizon standard.

      12.1 General

            A.     All Verizon central offices shall be engineered and grounded in accordance with
                   Verizon’s VZ 790-700-100 (fBA), 795-805-073 (fGTE) and VZ 330-100-100
                   (Verizon) series of Grounding Practices. The VZ 330-100-100 standard is intended to
                   define and describe the grounding and bonding topologies that shall be applied to all
                   new central office buildings constructed on or after February 1, 2003. Due to
                   differences in grounding strategies that existed prior to the merger between Bell
                   Atlantic and GTE, it is imperative that pre-merger standards continue to be used in
                   existing facilities.

                                all listed racks and shall not restrict the cable pile-up of the standard racks.

                   3.     When fiber duct is required, it shall be placed below the switchboard rack.

      13.3 Metallic Cable Racking Requirements - Location

            A.     The location of cable racks shall be such that the clearances required for installation
                   and maintenance of the ultimate equipment arrangement will be maintained, and in
                   conformance with existing office conditions. Fiber, switchboard, and power cables
                   must be segregated in new areas and in new line-ups. AC and DC power cables should
                   always be run separately from each other and laced. All common systems cable rack
                   shall have solid metal stringers. Panned rack shall not be used for power.

            B.     Cable racks shall not be located close to pipes, radiators, windows, doors, or any other
                   equipment that may subject the cabling to detrimental conditions.

            A.     Cable racks shall be installed so that no excessive load or binding will be imposed on
                   frames, racks, or other equipment attached to or adjacent to the cable racks, unless such
                   equipment is engineered to support the cable racks.

            B.     Cable racks shall be securely supported and fastened to carry and support the ultimate
                   cabling and equipment requirements per GR-1275-CORE.

            C.     Cable rack shall be engineered so as not to exceed the minimum requirements of the
                   cable (Bending radius, weight, type of cable, segregation, etc.) that they support.

            D.     Racks, troughs and pathways used to support cable shall be of the appropriate type for
                   the system (power, switching, etc.) and cable being supported.

            E.     Protection for rubber, neoprene and plastic jacketed power conductors when secured
                   shall consist of one (1) layer of 1/32” PVC or fiber insulator or two (2) layers of 1/64”
                   sheet fiber.

            F.     Transmit and receive cable drops shall be segregated and routed on opposite sides of
                   the bay/frame/cabinet unless otherwise specified on cabling plan.

            G.     All switchboard cable run on vertical or non-panned cable rack shall be secured with
                   lacing twine. Nylon cable ties shall only be used to secure amphenol connectors to
                   connecting blocks designed for this purpose and must meet the requirements set forth
                   in IP 72202, Section 13.14.

            H.     Cable racks for fiber cables shall be shall be sized to accommodate the largest
                   minimum bend radius of any fiber cable planned for that rack. Where the possibility
                   exists for the placement of slack, cable rack with a minimum width of 15 inches
                   shall be installed. All intersecting junctions of fiber cable rack at the same plane must
                   have 45 degree corner brackets per GR-1275-CORE, Figure 10-50. Refer to document
                   2006-506F-COE, “Fiber Optic Minimum Bending Radius Requirements” for further
                   information on bending radii for fiber optic cabling. Refer to IP 72202, Figure 13-1 for
                   the definition of minimum bend radius.

                   Note: In the absence of manufacturer’s specifications that include the minimum
                   bending radius of the fiber(s), the Rule of Thumb to determine the minimum
                   bending radius is summarized in the formula below:

                          Minimum Bending Radius = 10 x Outside Diameter of the Fiber Cable

                   The following formula can then be used to determine the appropriate width of the
                   cable rack based on the largest fiber cable planned for the cable rack:

                          Cable Rack Width = (Minimum Bending Radius in inches x 2) + ½ inch

            I.     The preferred panning material for cable racks is plastic. Plastic panning is acceptable
                   if it is stamped by the manufacturer to identify its’ oxygen index rating. Any plastic
                   panning installed must have the oxygen index rating of 28% or greater and information
                   facing the underside of the cable rack for immediate visibility and identification.

            J.     Fiber, PVC or other fire-rated (oxygen index >28%) insulating tubes shall be placed on
                   the hanger rods, which directly support cable rack stringers, or hanger rods that may
                   come in contact with cable.

            K.     Exposed ends of all cable racks shall be closed with end caps or closing details. Refer
                   to GR-1502-CORE, Figures 13-21, 13-22 & 13-23 for additional information on
                   closing details.

            L.     All fastening details, piece parts and other apparatus used in the assembly of auxiliary
                   framing and cable rack shall be the proper manufacturer specified type (i.e. cable rack
                   fabrications must be the type designed for solid stringer cable rack).

            M.     Lock washers under the nuts of friction fastenings (such as those used in superstructure
                   or cable rack applications) shall be external tooth. They shall be installed where the
                   possibility of movement exists. Split ring washers shall not be used to secure C clips or
                   G clips. An external tooth lock washer or no washer may be used to secure a C clip or
                   G clip. Refer to Flash 2007-211-COE (Split Ring Washers).

            N.     Cable rack and auxiliary framing shall be extended at least 2 ceiling inserts past an
                   added frame to allow for short interval additions.

            O.     Generally, cables are run between equipment locations using the shortest cable rack
                   route; however, it is imperative that consideration be given to the extent of cable pileup
                   on each rack in order to avoid blockage of the cable racks.

            P.     Cable and wire shall be routed as to avoid excessive pileup and/or blockage of cable
                   racks. The Survey Engineer or Installer as applicable should notify Verizon
                   Engineering before exceeding these limitations when it appears a safety or cable
                   routing issue exists. The Verizon Engineer will be responsible for determining if new
                   alternate cable racking/cable will be required. Refer to the following tables for pileup
                   limitations:

18.   CABLE DISTRIBUTION SYSTEMS (CDS’s)

      18.1 General

            For further information, refer to Section 13 of IP72013 and Section 18 of GR1502.

      18.2 Applications

            A.     For information, refer to Section 18.2 in GR1502.

            B.     Refer to Sections 13 and 14 in GR1502 and in IP72013 for cable rack provisioning
                   requirements.

      18.3 Cable Distribution Systems for Fiber Optic Cable and Associated Equipment

            A.     A dedicated cable pathway or rack shall be established from the fiber splicing location
                   to the FDF. Adequate bending radius must be provided in this pathway for the largest
                   possible building fiber cable. See Section 13.4 in this document for details regarding
                   the appropriate cable rack width. This pathway must provide the easiest access from the
                   splice to the FDF and must be designed initially for the ultimate capacity of the
                   intended FDF. Similarly, a dedicated pathway must be established over the FDF for
                   equipment fiber cables. If long vertical runs are necessary, interim bends may be
                   required to reduce the vertical tension per the manufacturer's specifications.

            B.     The FDF requires a two-pathway system. One pathway will be dedicated to the fiber
                   cable coming from the vault or CEF, and the other pathway will accommodate the
                   FOTS cable. Cable rack is the preferred pathway; however Fiber Protection Systems
                   may also be used if the limitations of these systems are adhered to.

            C.     All installed cable pathways must be distinctively labeled on both sides per IP72202.

            D.     Intra-building Fiber Cable and Jumpers

                   1.     All intra-building fiber optic cable shall meet the requirements of GR-409-CORE
                          (Telcordia Generic Requirements for Premise Fiber Optic Cable (Intra-
                          building)).
                   2.     When exiting the cable vault with fiber cable, the duct shall be fire stopped and
                          the building cable run on a dedicated fiber optic cable pathway system.
                   3.     If vertical runs are necessary, the fiber cable shall be secured in the vertical
                          orientation prior to a horizontal bend. Interim bends should also be used to
                          reduce the vertical tension as necessary.
                   4.     Bending radius restrictions specified by the fiber cable manufacturer must be
                          strictly adhered to in order to prevent damage to the fibers (typically 3 inches or
                          10 times the outside diameter of the cable, whichever is greater).
                   5.     Fiber jumpers shall be run in the approved Verizon Fiber Protection System. This
                          duct is a dedicated system that shall be stamped every 5 feet to indicate the
                          existence of fiber optics. The fiber protection system fittings have a bending
                          radius of 2 inches, therefore no fiber jumper with a minimum bending radius of
                          greater than 2” inches shall be placed in the protection system.

                   6.     Intra-building, multi-fiber or “breakout” cables shall be used for cabling between
                          the FDF and the fiber transmission or switching equipment. Such cables shall
                          utilize a “furcation assembly” to transition from the multi-fiber sheath to
                          multiple, single fiber sheaths at each terminating end. The length of these single
                          fiber breakouts shall be determined in a manner to meet the specific interconnect
                          requirements of the equipment. Where terminating on exposed locations (on a
                          circuit pack or front of a fiber distribution panel), the single fiber breakouts shall
                          be up-jacketed to a minimum of 1.6mm diameter with dielectric strength
                          members and capable of a sustained tensile load of 10lbf or more. Single fiber
                          breakouts consisting of 900µm buffered fiber without strength members shall
                          only be used for fully enclosed terminations (i.e. factory pre-terminated of fiber
                          distribution panel) that will not be subjected to movement or maintenance
                          activity. Refer to Document 2004-045-COE for further details regarding 900µm
                          fiber.
                   7.     A minimum of slack or excess cable should be placed on cable pathways above
                          the FDF. Slack shall be placed on the cable pathway above the Network Element
                          where possible, rather than above the FDF. Slack shall be limited to 10 feet or
                          10% of the fiber length, whichever is less.

            E.     Outside Plant (OSP) Fiber Cable

                   1.     OSP fiber cable not designated OFNR, OFCR, OFNP or OFCP shall not be
                          brought past the CEF or cable vault unless in metallic conduit.
                   2.     Metallic members of OSP fiber cable shall be grounded to the OPGP/MGB via
                          Cable Entrance Ground Bar (CEGB “fBA “) / Cable Vault Ground Bar (CVGB
                          “fGTE”) according to the requirements stated in the Verizon Central Office
                          Grounding Practices, 790-700-100 (fBA) 795-805-071 (fGTE) and VZ 330-100-
                          100.
                   3.     Refer to Telcordia Generic Requirements for Optical Fiber and Fiber Optic Cable
                          (Outside Plant) GR-20-CORE. OSP cable should be spliced in the vault or CEF
                          to a field connectorized building cable or a pre-connectorized building fiber cable
                          from the FDF. In multi-story buildings, the building fiber optic cable should be
                          run through an optical cable rearrangement facility (OCRF), or splice bay.
                   4.     When installing the OSP cable in the CO, the following requirements must be
                          observed:

                                When exiting the cable vault or CEF area, the OSP cable shall be fire-
                                stopped at each end and grounded appropriately.
                                Cable splices in the CEF area shall be made within fifty (50) feet of the
                                cable building entrance.

                   NOTE: Detail Engineer must have Verizon’s permission to direct the installer to
                   run fiber OSP cable out of the cable vault or CEF into the CO.

                   reference or by reference to drawings on which this information is provided. Lighting
                   fixture assemblies other than those specified on the drawings may be furnished only
                   with the approval of Verizon.

            B.     All AC conduits shall be metallic, of the size and type specified, positioned, securely
                   fastened, or otherwise installed in accordance with specific specifications and
                   drawings, which meet the requirements of the National Electrical Code (NEC).

            C.     Conduit shall not be run in locations normally occupied by auxiliary framing, cable
                   racks, ladder tracks, cover batteries, etc. Where possible, conduit shall be run parallel
                   and adjacent to superstructure to assure maximum headroom, and to provide easy
                   access to cable racks.

            D.     All non-terminated exposed conduit ends must be closed with end caps designed for
                   that purpose.

            E.     Conduits shall be placed so as not to block future cabling, ladders, etc.

                   shall be located at the end of each aisle in the end-guard, column, or wall, etc. One 3-
                   way switch is located on the left upon entering the aisle and the other on the right when
                   leaving.

            G.     At end lineups and at incomplete lineups where the absence of an adjacent lineup of
                   frames prevents the mounting of the switch, the switch shall be located adjacent to the
                   last rack / frame in that lineup.

            H.     All frame and aisle lights shall be located so as not to interfere with cable racks, rolling
                   ladders, ladder tracks, and auxiliary framing or other obstructions, and electronic
                   equipment.

            I.     When lighting equipment is engineered for an installation in which equipment for more
                   than one system is provided, the lighting shall be furnished according to the
                   requirements for the respective systems.

            J.     When a line of tall frames (11’-6” or 9’-0”) is paralleled by a row of shorter frames (7’-
                   0”), the aisle lights shall be located in accordance with the requirements of the taller
                   frames.

                   specifications, IP72013 and any subsequent documentation from the manufacturer and /
                   or Verizon.

            C.     Placement of Central Office Lighting Sensors shall be such that there is minimal risk of
                   damage to the sensor from installation activity.

            D.     A minimum of one sensor will be placed in every Central Office aisle.

            E.     Sensors shall be placed such that lighting will be activated from anywhere in the aisle
                   (i.e. from the location of the last end guard to the farthest end guard at the opposite end
                   of the aisle). Periodic sensor adjustment may be needed as the environment changes
                   (i.e. equipment is added) to ensure that the field of vision is optimized.

            F.     Sensors must be placed below cable racking arrangements, at a height of
                   approximately 8 feet to ensure the sensor field of vision is maximized.

            G.     Sensors shall not be installed directly in the path of any air conditioning or heating duct
                   where venting occurs, as this will impact the performance of the sensor.

22.   OPERATIONS SUPPORT SYSTEMS (OSS)

      22.1 General

            A.     The equipment installation design shall ensure that Verizon personnel have an optimum
                   interface with the installed equipment. Information regarding interface systems shall be
                   shown on the Central Office record / drawings.

            B.     Generally, equipment maintenance should be performable at either the fault location or
                   at the Maintenance Control Center (MCC). Equipment added in a Verizon location
                   should be engineered to provide assurance that at either location maintenance
                   commands are responding appropriately.

            C.     Equipment shall be engineered in such a manner that maintenance routines or repairs
                   can be performed without interrupting calls in progress. Some possible exceptions are
                   permanent switched connections and systems that do not have maintenance channels or
                   spare equipment.

            D.     All working items must be taken out of service by Verizon personnel when required by
                   work operations. Instructions to installers in the installation specification shall include
                   directions to contact Verizon personnel for assistance.

            E.     Indicator lamps, readouts, and manually operated switches shall be mounted so that
                   they are visible from all angles at the front of the frame and shall not be obscured by
                   equipment, framework, wire, or cable.

            F.     Refer to BA 190-100-911 (Magnetic Tape and Disk Management for Operations

23.   ALARMS

      23.1 General

            A.     Alarm systems shall be engineered based on the functions performed by the equipment
                   and the alarm severity. The three main categories of alarms are critical, major, and
                   minor. Critical and major alarms (highest priority alarms) shall be associated with
                   equipment that brings revenue or is essential to the call processing functions. Minor
                   alarms (low priority alarms) shall be associated with equipment whose failures would
                   have little impact. The means of sending alarms associated with transport network
                   elements vary across the Verizon region. Until Verizon completes the standardization
                   of alarms, it is the responsibility of the Detail Engineer to become familiar with the
                   alarms in each of the various areas.

            B.     All network elements, which have the ability to provide an X.25 (or equivalent) alarm
                   signal, shall be connected to the appropriate alarm device, such as an alarm
                   concentrator switch, router, modem, etc., for connection to the Network Monitoring
                   and Analysis System (NMA).

            C.     Network elements which do not have the ability to provide an X.25 (or equivalent)
                   output but are deemed necessary to be monitored by the NMA System, shall have their
                   alarm leads cabled to a common point (usually the MDF) to be cross connected to an
                   alarm collection device (i.e. Discrete Alarm Monitoring System – DAMS) for
                   transmission to the appropriate alarm reporting center.

            D.     Central Office alarming is implemented via the following types:

                   1.     Audible Alarms are sound-producing devices usually located external to the
                          equipment which they serve. Bells, tone bars, ringers, gongs and buzzers are
                          employed to signify a major failure to a service situation. Typically, frequency
                          sound rate and duration determine the category of the associated problem.
                          Controls permit the alarms to be grouped, cut off and transferred.
                   2.     Visual Alarms vary in type from light displays on a control console to flags
                          extended from blown fuses. In central offices with specialized alarm systems,
                          zones are created. Lineups of equipment are grouped to form aisles, aisles to
                          zones, and zones to floors. The color of the lamp indicates the seriousness of the
                          problem and the action to be taken. Lights and flags are usually associated with
                          and located near the equipment being served. The visual indication shall provide
                          the maintenance person with the exact bay location of the alarmed circuit.

            E.     Refer to the following documentation for information on building alarms:

            A.     In some cases, the manufacturer’s standard drawings may not be sufficient to engineer
                   the equipment and interface drawings may be required.

            B.     Interface drawings are created to establish a permanent record of information that
                   cannot be easily obtained from various Detail Engineer drawings and which is required
                   to complete the engineering, acquisition, installation, and interconnection of
                   equipment.

            C.     Interface drawings are usually prepared by the manufacturing Detail Engineer to
                   facilitate the interconnection of a Detail Engineer’s equipment with existing or
                   proposed common equipment such as power, alarms, distribution frames, etc., required
                   for proper functioning of the new equipment. Interface drawings shall not contain any
                   information may be considered proprietary to a Detail Engineer.

            D.     When available, the manufacturer-supplied interface drawings shall be used; however,
                   when a manufacturing Detail Engineer does not provide interface drawings, the Detail
                   Engineer may be requested to prepare a permanent record of the required interfaces.

            E.     The information typically contained on an interface drawing includes the following:

                   1.     CO records common to more than one vendor, such as floor plans, cable rack
                          plans, and lighting plans, contain information that may be applicable to all
                          vendors.
                   2.     Detail engineers with activities pertaining to common CO records that they do
                          not maintain will post their changes and additions on the copy provided to them
                          and submit the marked up copy to Verizon’s records systems. Vendors are
                          advised not to post proprietary information on these common records, as they
                          will be shared with others.

            G.     A reference copy of the current issue of CO records showing existing wiring and
                   equipment conditions prior to extensive changes shall be maintained by the detail
                   engineer and be made available to Verizon until job acceptance.

            H.     Verizon records maintained by a Vendor shall be kept confidential and shall only be
                   disseminated to other parties under written permission from Verizon

            I.     CO record maintenance shall include corrections due to changes and/or relocations,
                   which occurred during the installation. The Detail Engineer is responsible for returning
                   corrected documentation.

            J.     The Drawing / Office Record section of the specification must contain all changed
                   drawings and records used for engineering.

32.   INTERCONNECT DRAWINGS

      32.1 General

            A.     In some cases, the manufacturer’s standard drawings may not be sufficient to engineer
                   the equipment, and interconnect drawings (also refer to as Interface drawings) may be
                   required.

            B.     Interconnect drawings are created to establish a permanent record of information that
                   cannot be easily obtained from various Detail Engineer drawings and which are
                   required to complete the engineering, acquisition, installation, and interconnection of
                   equipment.

      32.2 Purpose

            A.     Interconnect drawings are usually prepared by the manufacturing Detail Engineer to
                   facilitate the interconnection of a Detail Engineer’s equipment with existing or
                   proposed common equipment such as power, alarms, distribution frames, etc., required
                   for proper functioning of the new equipment. Interconnect drawings shall not contain
                   any information that may be considered proprietary to a Detail Engineer.

            B.     Interconnect drawings are to be used as an engineering aid. They are not intended to be
                   used as a replacement for manufacturer’s standard drawings, but are to be used as
                   supplements to them. In any case, the Detail Engineer must carefully review the
                   information contained on the interface drawings to ensure that it is current and
                   applicable to the job being engineered.

            C.     The information typically contained on an interconnect drawing includes the following:

                          Block diagram showing equipment to be connected
                          Schematic drawing
                          Equipment or product identification
                          Manufacturer’s name
                          External connecting information
                          Cross – Connect Interfaces
                          Cable/wire selection details/plug and connector
                          Numbering scheme (for MDF, DSX, FDF, etc. stamping)
                          Installation specifications

      32.3 Interconnect Drawing Availability

            A.     When available, the manufacturer-supplied interconnect drawings shall be used;
                   however, when a manufacturing Detail Engineer does not provide interconnect
                   drawings, the Detail Engineer may be requested to prepare a permanent record of the
                   required interfaces.

            B.     Interconnect drawings originated by a Detail Engineer shall be updated and maintained
                   by that Detail Engineer, and each new issue of an interconnect drawing shall be
