1.0 Product Description

1.1 Executive Summary

Throughout the 1960s, telephone companies began to deploy digital switches into their central
offices. Calls originated as analog and converted to digital at the switch. They were then sent
digitally on to another central office, where they were converted back to analog and delivered to
their final destination. During the 1970s, the telephone network was slowly upgraded to better
switching hardware and higher volume connectivity, such as T-1‟s were provided directly to
customer premises. The phone companies explored digital technology further and ISDN research
began.

Initially, Bell Labs was responsible for the majority of the ISDN research efforts. After the
divestiture of AT&T in 1984, Bell Labs continued their research but each of the seven regional Bell
operating companies started their own efforts. As a result, the requirements, offerings and pricing
were specific to each operating company and there was no interoperability.

The major difference between regular dedicated access lines and PRI access lines is not the actual
local loop but the Customer Premise Equipment (CPE) that is on each end. Hardware
manufacturers were discouraged with the lack of standards and reluctant to develop the needed
equipment. ISDN deployment was slow. Over time, standards were developed and published and
ISDN was rolled out in major metropolitan areas in the early 1990‟s.

Recent changes in legislation have brought ISDN back to the forefront. In January of 2003, the
Telemarketing Sales Rule (TSR) was amended. One of the key changes was that telemarketers
must make a best effort to deliver ANI (Automatic Number Identification) to the end user. They
have 365 days to comply with this amendment.

The TSR applies to companies that make interstate telemarketing calls. A company is legally
responsible for this information even if they hire an outside telemarketing firm. The number
presented to the customer must be a valid number and one that customers may call to reach a
company representative.

      Highly Trained Customer Support Personnel to handle billing inquiries and general
       customer service questions
      ISDN is supported on both inbound and outbound calls.
      ISDN can be used in conjunction with eMeritus Teleblock.
      More PBX users can be supported than over traditional T1 spans. Further efficiencies can
       be gained by supporting as many as 20 PRI spans with one “D” channel (plus a back-up “D”
       channel, just in case).

1.3 Benefits

The benefits to be gained from the ISDN/PRI offering are numerous. These include, but are not
necessarily limited to:

              The superior quality of transmission to analog trunking.
              ISDN/PRI offers desirable features such as ANI.
              The cost of ISDN/PRI can be very attractive, depending on the LEC and the
               customer‟s location.
              Faster call set-up time.

1.4 Technical Overview


Before ISDN, US phone lines used “in-band” or “channel associated” signaling. In other words,
the signaling shares the same channel as the voice. On analog lines, the channel is the wire pair
and it carries either:

   1) Dial pulses for rotary dialing or
   2) Dual tone multi-frequency DTMF.

Circuits either used ground or loop start signaling. Multifrequency (MF) pulsing was used in
analog telephone systems to transmit control information needed to set up a connection between
switches. Newer systems called common channel signaling (CCS) systems use a separate common
channel for signaling.

There are two types of out-of-band signaling: SS7 and ISDN. SS7 is physical out-of-band signaling
with a separate physical channel. ISDN is a logical out-of-band set-up where user data and control
data share the same physical link but the traffic is separated onto different channels.

An ISDN transmission circuit is merely a logical grouping of data channels. Each of these channels
has a specific purpose and handles a specific amount of bandwidth. By grouping these channels in
different configurations, ISDN can be used for almost any digital transmission application
regardless of the bandwidth required. ISDN is an access architecture.

User-to-Network Interfaces
Voice Product Sourcebook                                                                        4
CONFIDENTIAL AND PROPRIETARY: Use, disclosure, reproduction or distribution of this information
outside official eMeritus channels is expressly prohibited.
                                                                  © eMeritus Communications 1/03
ISDN has two types of User-to-Network (UNI) Interfaces: Primary Rate Interface (PRI) and Basic
Rate Interface (BRI). PRI has 24 DS0 channels consisting of 23 Bearer channels and 1 Data
channel. This arrangement is referred to as 23B + D. BRI consists of 2 DS0 Bearer channels and
(1) 16Kbps Data channel. BRI is primarily used for residential and home-office use.

The North American version of ISDN PRI is based on the use of T1 Carriers and the Digital Signal
Level 1 (DS1) format. A DS1 signal contains twenty-four 64 Kb/s time slots plus an 8 Kb/s time
slot for framing. The first 23 time slots are B-channels that support access to circuit-switched
services (no X.25). The 24th channel is the D-channel, which is used for out-of-band signaling
protocol. The call setup process on PRI is much faster than a standard T1, and often many more
calls are completed on a PRI than on a T1.

ISDN Channels

An ISDN transmission circuit is merely a logical grouping of data channels. Each of these channels
has a specific purpose and handles a specific amount of bandwidth.

The B- Channel

The core of any ISDN circuit is the bearer channel, or B-channel. A single B-channel carries
64Kbps of digital traffic. This traffic can be digitized voice signal, digitized video, or raw data.
The 64Kbps throughput is the perfect amount of bandwidth to sample a voice signal.

The D-Channel

The D-Channel is primarily used for out-of-band messaging and signaling. This allows the call
setup and teardown signals to have their own dedicated channel, while the entire bandwidth of the
B-channel is left for the actual data.

D-Channels can be different sizes, depending on how many B-channels they are controlling. As
more B-channels are in use, then more signaling is needed. For a Basic Rate Interface (with two B-
channels), the D-channel is a 16Kbps pipe, while a Primary Rate Interface (with 23 B Channels)
requires a 64K Pipe.

Signaling System 7 (SS7) is the language used to communicate between phone company switches.
DSS1 is the language that travels on a D-channel and is the little brother to SS7. DSS1
communicates between the customer premise equipment and the telephone company‟s switch. It
also handles the setup and teardown of calls.

ISDN relies on an “out of band” signaling system to accomplish circuit switching. Based on data
messages sent in the Data or D channel part of the access link, the call is directed by the switch,
which may take action on parts of a message and forward other parts to other switches in the
network.
Voice Product Sourcebook                                                                        5

ISDN is the signaling protocol between the customer premise equipment while SS7 is the signaling
protocol between switches.


1.5 Engineering Specifics

A DS-1 Primary Rate Interface (PRI) is divided into TDM channels using standard T-1 frames.
Standard PRI requires Extended Superframe (ESF) with B8ZS. Customers that cannot support
B8ZS can use D4 framing with AMI. In this case, the D-Channel will be maintained as a 56k
configuration.

Customers have the ability to choose between Facility Associated Signaling and Non-Facility
Associated Signaling (NFAS). Facility Associated Signaling (FAS) can exist when there is a one to
one correlation between PRI and D channel. Every T1 has a D channel. NFAS is when more then
one T1 is under control of the same D channel. If there isn‟t D channel redundancy, the D channel
limit is two PRI‟s per D Channel. If there is redundancy for the D channel, the limit is (20) PRI‟s
per D channel.

Customers are responsible for purchasing and installing their own ISDN DS1 cards for their PBX.

1.6 Features

The feature sets between ISDN PRI and ISDN BRI are substantially different. ISDN BRI features
are meant to give customer‟s PBX-like features such as Caller ID, Call Hold, Call Conferencing,
Call Forwarding and multiple function calls. eMeritus Communications does not offer ISDN BRI.

On the other hand, ISDN PRI has a limited feature set. Many of the features of ISDN, such as
improved quality and faster call set-up, are now available through either Feature Group D or digital
access lines.

In addition to the following features, all other features listed in the Dedicated Voice section are
available with eMeritus Dedicated ISDN Access. For example, 7 digit account codes are available
on ISDN circuits.

Directory Number

The directory number (DN) is simply the normal ten-digit phone number the phone company would
assign any analog service. With ISDN service, however, there is much more flexibility in the use of
the directory number. The directory number is only a logical mapping, and does not have the one-
to-one relationship with your lines that analog service provides.

Calling Party Number


Voice Product Sourcebook                                                                        6
CONFIDENTIAL AND PROPRIETARY: Use, disclosure, reproduction or distribution of this information
outside official eMeritus channels is expressly prohibited.

The default DN can be network or customer provided. The network provided number is the user
provided default DN assigned to an interface. If a PBX provides a calling party number during call
origination, the originating switch screens the number and verifies that it is assigned to the PBX. If
the user-provided number passes screening, the user-provided number is used for call processing
and not the default DN.

The network provided number capability ensures that a Calling Number Identification Service
(CNIS) subscriber receives the calling party number information on incoming calls.

Privacy of Calling Number

The Calling Number Privacy capability allows a user to block delivery of their calling party number
information to a CNIS user.

Call-by-call Service Selection

Call-by-call Service Selection allows the PRI CPE to access services provided by the network using
any B-channel on the PRI on a per-call basis. Network managers have the ability to route calls, on
a call-by-call basis, based on attributes of the incoming call.

Screening Functions

This capability allows the originating switch to compare a calling party number received from the
calling user against those numbers assigned to the user.

Subaddress information

The subaddress information is in addition to the DN. It may be used at the terminating end of a call
to route the connection over a private network or to a specific station.

Calling Number Delivery

This option allows the customer to receive the DN of the calling party.

Trunk Signaling

Provides out-of-band D channel signaling using Q.931 protocol.

1.7 Alternative Solutions

On January 29, 2003, Congress approved amendments to the Telemarketing Sales Rule (TSR).
Companies that market by telephone have until January of 2004 to comply with the new legislation.
One of the main requirements is that companies must make a best effort to provide a valid Calling
Party Number to end-users.
Voice Product Sourcebook                                                                        7

It should be noted that ISDN is not the only alternative for customers to provide Calling Party
Number to the called party. Depending on the customer‟s equipment and the network switch, ISDN
may not be necessary.

In the Alcatel DEX switch today there exists a known limitation that prohibits delivery of Calling
Party Number on 1-Stage Digital Access Lines (DAL)'s. In a 1-Stage DAL, the customer cannot
send the Feature Group D protocol and we do not get originating ANI from the customer. In these
cases, it is possible to file a default ANI in the DEX switch database. However, that ANI is passed
as Charge Party Number.
Customers connecting to eMeritus‟ Alcatel DEX switches that have a 2-stage [or multistage PBX]
can send originating ANI information using Feature Group D Protocol. In a 2-Stage PBX,
eMeritus will receive the ANI from the customer's equipment and have the option to send that
"received" ANI as either Calling Party Number or Charged Party Number. In a 1 Stage DAL,
eMeritus only receives the terminating number from the customer and can only forward a Charged
Party Number. Some LEC‟s use the Charged Party Number as the default Calling Party Number
and some do not.
The following are the associated digit strings:

       For International Calls:
       >KP+138+0457+001+ST KP+00+NPANXXXXXX+ST KP+IDDD Number+ST
       Note: For operator assisted IDDD calls, replace 138 with 158

       For Domestic Calls:
       >KP+00+NPANXXXXXX+ST KP+Destination Number+ST

Customers connecting to a DMS switch have two options. If they have a 2-stage switch, they can
program their PBX to send the Feature Group D protocol and ANI information is passed on a per
call basis. If the customer has a one stage PBX, a default number can be pre-programmed in the
DMS switch and the switch delivers the Calling Party Number to the terminating end.

3.0 Target Market
ISDN PRI Dedicated Access provides Private Branch Exchanges (PBXs) with the ability to manage
multiple call types such as DID, WATS, 800 and foreign exchanges.

ISDN PRI Dedicated Access is of particular interest to customers that perform telemarketing
activities. ISDN PRI in conjunction with eMeritus Teleblock enables telemarketers the ability to
comply with legislation and manage their calls more efficiently.

ISDN D channel messages pass between the PBX and the network. When placing a call, the initial
call set-up message dynamically establishes the features (and service) to be provided. For incoming
calls, the call-by-call service selection gives a network manager the ability to route calls. This call
routing, again on a call by call basis, contains the attributes of the incoming call.

Managing Inbound Calls

ISDN provides a number of advanced capabilities to allow a user to more efficiently manage
incoming calls. Some of the features that make this possible are: Calling Number and Name ID,
Multiple Telephone Numbers on the same line, Multiple Call appearances of the same number,
Shared Call Appearances between terminals and Analog Call Appearances which allow an ISDN
user to answer an analog number from their ISDN set.

4.0 The Network
                                               SM
At the heart of eMeritus Dedicated PRI Access is the eMeritus network. This network is one of the
largest in North America. Further, it is a 100 percent digital network based on leading-edge
technology and service platforms.

All facilities are provided and maintained to the relevant International Telephone Union-
Telecommunications (ITU-T) recommendations and other globally recognized standards.

Dedicated voice customers currently are connected to the U.S. network via dedicated local lines.
The network provides 100% local access in all U.S. LATAs with all international calls routed in
and out through our international gateways.

Business customers, particularly in the USA, expect high quality routes with minimum termination
problems. Although a “standard” does not exist, most expect a level of service equal to the service
provided by dominant carriers in their respective countries.

4.1 U.S. Domestic Network

 eMeritus Communications is a wholly owned subsidiary of VarTec Communication and has been
established as the Business Sales Division of VarTec Communications. eMeritus and VarTec
together operate one of North America‟s most advanced voice networks.

4.2 The International Network

eMeritus, along with our partner carriers, run an international network. This network consists of
12,000+ cable circuits in addition to 7,000+ direct satellite circuits. This complex network of cable
circuits and direct satellite circuits are provided to some 275 carriers worldwide. On routes where
both facilities are available, then preference is given to cable. The U.S. network consists of
interconnections to every major LEC, with SS7 signaling deployed where available. The US
network consists of 200,000 DS1 route miles and 145,000 DS 3 route miles.

4.3 Call Processing and Routing

eMeritus will receive all customer calls from their CPE in standard national or international format.
For U.S. national calls, eMeritus must receive calls in standard 1+ format. International calls must
be formatted with U.S. Standard Access Prefix (SAP) 011, plus country code.

   Caller picks up handset and dials international telephone number in the format:

                                   011 + Country Code + number
                                               OR
                                      1 + NPA- NXX- XXXX

    PBX will receive dialed digits and will analyze destination digits. CPE will recognize 011 as
     Standard Access Prefix for eMeritus Dedicated Access calls or 1+ for US national calls.
    CPE will seize available T-1 channel based upon channel seizure method customer establishes.
     Customer CPE sends digit string and all related signaling information into the POP.
    eMeritus POP performs minimal call processing, call is sent to HUB switch for call processing
     and routing
    eMeritus DEC 600 receives dialed digit string and analyzes origination and dialed digits
    DEC600 routes call to international destination
    Once call is cleared down, DEC600 releases call, frees up channel and creates CDRV of call
    CDR is deposited to eMeritus traffic billing system for rating

eMeritus is not a local carrier and cannot accept calls in local format at this time.

5.1 Sales Strategy

The eMeritus PRI Access product will be sold to the business community that has need for ISDN‟s
special features. The most popular of these features is Calling Party Number for both inbound and
outbound calls. eMeritus does not offer Calling Party Name (CNAM) at this time. Certain
customers may be too far from a POP to allow eMeritus to be cost competitive. In these cases, the
local loop costs will exceed the savings eMeritus offers corporate customers. For those customers,
eMeritus will offer special pricing and “Virtual POPs.” Sales should alert product management of
those areas requiring special pricing and local loop incentives. The product will be positioned with
competitive domestic and international rates. Sales points will be:

      Highlight eMeritus experience
      Demonstrate savings offered by eMeritus versus other carriers
      Emphasize our reliable global network and connectivity - more than 240 countries and
       territories spanning all seven continents.
      Emphasis eMeritus stability - deal with one company; not an unstable or uncertain alliance.
      Emphasize the additional network resources provided by the VarTec Domestic and
       International Network.

Appendix A: AT&T Feature Descriptions (AT&T TR 41459 June 1999)
The following features are some end-to-end ISDN connectivity features based on the AT&T TR
41459 document. This document provides a reference for feature control interface specifications
and is used by many vendors during product design.

These features also assume product supports ITU-T Q.931 user side protocol and ITU-T Q.921
network side protocol.

    64 Kbps Clear/Restricted – Switched end-to-end digital connections will be supported at a
     data rate of 64 Kbps Restricted or 64 Kbps Clear. Call originations of 64 Kbps and higher
     will not be delivered from the network if the egress route does not support 64 Kbps
     connections.

    Wideband switching – The ability to switch 384K and 1.536Mbps end-to-end connections.

    CBC – call-by-call service selection. The user can designate the desired service to the
     network, on a Call-by-Call basis by channel. The network can also indicate the service type
     on an incoming call.

    Service Provisioning Option – Customer option at provisioning to select certain channels
     for different uses.

    CPE Management of a CBC Pool of Channels – CPE control of channel service type.
     Instead of dedicating specific time slots to specific services, the customer may choose to
     treat some or all time slots as belonging to the call-by-call pool. The CPE can choose to
     limit the maximum number of simultaneous calls of each type on the call-by-call pool.

    Subscription Screening – call-by-call service type screening. For each subscribed service,
     the customer must have either a pool of channels dedicated to that service, or the CBC pool
     of channels must be provisioned to carry calls of the service, or both. The call will be
     rejected if the customer is not provisioned to carry calls of the requested service on the pool
     of channels on which the call arrives.

    Service Identification on Access – information element checking before access. Provides
     the type of service being requested. The network will reject if the service type does not
     match.

    Service Identification on Egress – information element checking before termination to
     customer CPE.
   
    Screening on CBC TG – screening on call-by-call basis by TG.

    Screening on Single Service TG – screening TG-to-TG service type check.

    Channel Hunt Algorithm – efficient channel utilization of an access interface.

    CPN – Calling Party Number to the network.

    CPN/BN Privacy Optioning – option of billing number delivery to the called user instead
     of CPN.

    CPN/BN to Terminating End – delivery of BN to terminating end.

    Information Indicator (II) Digits Delivery – terminating user receives information about
     the originating call (e.g. coin, cellular service).

    Delivery of the Dialed Number ISDN Direct Egress Service – receive the originally
     dialed number in the CPN element.

    COLI – Connected Line Identification Presentation.

    UUI – User-to-User Information exchange (MA UUI, CA TSC and NCA TSC).

    B-Channel Negotiation – allows CPE to choose the B channel for an incoming call.

    Causes and Diagnostics – diagnostic cause generation.

    1+and 0+-call redirection – allows non-PRI users to dial PRI user when calls do not
     complete.

    Information Forwarding 3 (INFO 3) – allows ESPs to collects caller digits from calling
     party.

    CINFO – Caller Information Forwarding.

    Access to Operator Services – access to operator services provided by the network
     provider.

    Toll Free Redirection – allows for subscribers to transfer or redirect an answered call to
     another location.

    Dial-Around – allows customer to select an alternate toll carrier for long distance.

Appendix B: DMS Services and Features for the USC DMS-250
The following represents a partial list of features offered on the DMS-250. These features are those
that could potentially be used by eMeritus customers.

Software Answer

       Audio Tone Detectors
       Answer Supervision Distinction
       Operator Services Bridging
       Pooled Echo Cancellers
       Switched Digital Data Service (SDDS)

Call Authorization

       Authorization Codes (AuthCodes)

       Authcodes are 7-digit codes that are used for the following purposes:
             - To identify a subscriber
             - To bill a call to a subscriber
             - To screen against unauthorized access to the network
             - To indicate class of service available to the subscriber
             - To indicate special features available to the subscriber

       Security Codes

       Security codes are in the form of PIN digits. They are multidigit DTMF codes used as
       another level of screening beyond the authcodes. PIN digits are of variable length, ranging
       from 0 to 4 digits inclusive.

       Account Codes
       Account codes are 2 to 7 digit DTMF codes used to allow chargeback of calls to projects,
       departments, or accounts. The requirement to enter an account code is specified by the
       authcode parameter.

       Calling Line Identification

       Calls can be screen based on authcode or Calling Line Identification (CLID). As part of
       PRI-originating call processing, the CLID and CALLTYPE origination data is collected
       from the incoming SETUP message. The ten-digit CLID identifies the originator for billing
       purposes. The call type determines how calls are translated and what type of screening is
       required.

       Reorigination – Allows the caller to place numerous calls without the necessity of re-
       entering the billing number (after calls such as calling card number, ACCT code or Auth
       Code). During the conversation or anytime after the completion of the dialing sequence, the
       caller can press the # key to gain attention of the carrier access and authorization code. In
       response, the switch sends the caller a dial tone so that another number can be dialed.

       Dialing Plans

       Customers may require that certain types of dialed numbers require an authcode, TCN or
       account code validation. The following table will illustrate some examples.

                   Type of Number                                  Numbers dialed
       Seven-digit DDD                                NXX-XXXX
       1+seven-digit DDD                              1+ NXX-XXXX
       IDDD                                           011 + CC + NSN
       1 +Ten-Digit DDD                               1 + NXX-NXX-XXXX

       Bearer Capability for PRI

       The DMS-250 switch supports the following BC for PRI trunks:
             - Speech
             - 56 kbit/s unrestricted
             - 64 kbit/s unrestricted
             - 64 kbit/s restricted
             - 3.1 kHz audio

        Calling Number Delivery

        The purpose of the calling party number (CGN) IE is to identify the origin of the call. The
        calling number delivery service provides this number to the called party except when inter-
        networking from a PTS trunk.

        Actions at the originating exchange are as follows:

        When a SETUP message is received from the calling user, then the network will perform a
        validation that the CGN IE is included. If the CGN is included, then the following rules for
        the calling number delivery apply:

              If the screening indicator is not present in the CGN, it is set to user-provided, not
               screened and the calling party number provided by the user is sent unchanged in the
               outgoing SETUP message that goes to the terminating PRI. If the screening
               indicator is present in the CGN, it is relayed to the terminating PRI.

CONFIDENTIAL AND PROPRIETARY: Use, disclosure, reproduction or distribution of this information
outside official eMeritus channels is expressly prohibited.
                                                                  © eMeritus Communications 1/03
              If the presentation indicator is provided in the calling party number, it is passed
               unchanged to the terminating PRI. Otherwise, it is set to the subscription default of
               „value presentation allowed‟.

       If the SETUP message does not contain CGN IE, the following rules will then apply:

              If the network uses the default destination number (DN) for this originating PRI to
               pass into the terminating PRI. The numbering plan indicator (NPI) of the IE is set to
               telephone numbering plan. If the option field DELCGN is not entered, the CGN is
               not delivered to the terminating agent (the CGN IE is not delivered).
              The screening indicator is set to „network-provided‟ and the presentation indicator is
               set to the default value of „presentation allowed‟.

       Actions at the terminating exchange include:

              When the network initiates a call to the user, a SETUP message is sent over the
               terminating PRI. If the originator of the call is a PRI trunk, the actions described in
               the preceding section, “Actions at the originating exchange,” are taken.

              If the originator is a FGD or FGC, the CGN is relayed as received in the ANI of the
               originating trunk. In this case, however, the information digits received from the
               incoming PTS trunk are not relayed to the terminating PRI.

              If the CGN is not available due to inter-networking with a PTS trunk, then the CGN
               IE is not sent over the outgoing PRI. This implication here is that the PI and SI
               fields are also not delivered.
