Product Description
Qwest’s retail telecommunication service, Asynchronous Transfer Mode (ATM), is available for
resale by Competitive Local Exchange Carriers (CLECs) to their end-users. Additional information
about resale of Qwest’s retail services can be found in Resale – General. (Link blue text to:
http://www.qwest.com/wholesale/pcat/resalegeneral.html)
ATM is a connection-oriented communication service that uses ATM technology. The service
provides your end-users with high-speed, low-delay, information transfer capacity that supports
applications that require near-real time mixed media (e.g., data, video, image, voice).
ATM requires end-user terminal equipment that functions as a multiplexer, bridger, router, hub or
ATM switch. This equipment is purchased separately from Qwest ATM Service and must meet
industry standards. The terminal equipment accumulates your end-user’s traffic and puts it into a
cell relay format suitable for transmission over the Qwest ATM Network.
Loop Diversity and/or Avoidance as defined under the Private Line Transport Services in Federal
Communications Commission (FCC) 1 or the state specific Tariffs/Catalogs/Price Lists (Link blue
text: http://tariffs.qwest.com:8000/) is available with ATM, however additional charges may apply.
The components that make up Qwest ATM Service are:
    Network Interface – The point that your end-user’s data transmission enters the network that
    supports ATM. It is the point of interconnection between Qwest’s communication facility and
    your end-user’s terminal equipment.
   Digital Service Level 1 (DS1) and Optical Access Link (OAL) – Provides access to the ATM
    Network by connecting your end-user’s facilities at the network interface with a corresponding
    ATM cell transfer element. This element is only available at ATM service points.
   Stand-alone Optical Access Link (SAOAL) – Connects your end-user’s facility to ATM
    Networks provided by service providers other than Qwest. Private Line Transport mileage
    may be required in conjunction with a SAOAL in order to connect your end-user’s serving
    wire center or node with the serving wire center or node of another ATM provider.
   Inverse Multiplexing over ATM (IMA) -Allows bandwidth increments between DS1 and Digital
    Service Level 3 (DS3) levels using DS1 access links. IMA utilizes 2 to 8 DS1s and bundles
    them together to create a solid bandwidth increment of 3.045, 4.567, 6.090, 7.613, 9.135,
    10.658 or 12.180 megabits (Mbps).
   Port – Physical entry point into the ATM Network for OAL or other compatible private line
    facilities, such as DS3 service. They are the originating and terminating points for Virtual
    Path Connections (VPC) and Virtual Channel Connections (VCC). The ports include the
    electronic equipment used in connecting these service elements to the ATM Network. Your
    end-user will be able to allocate bandwidth to applications at their designated transmission
    speeds
   Logical Connections – Connections that function as bi-directional Permanent Virtual
    Connections (PVCs). ATM will support a point-to-point logical connection configuration
    between two ports. Logical Connections include:
          Virtual Channel Connections (VCC) – Logical connection from one ATM port to
              another ATM port within the Qwest ATM Network. VCCs are available with all ATM
              class of service levels.
          Virtual Path Connections (VPC) – Collection of VCCs routed together as a unit for
              which your end-user has the ability to manage the speeds of the individual VCCs
              within the end-users designated bandwidth. VPCs are available with all ATM class of
                                              Page 1 of 9

              service levels, at end-user -selected speed(s) depending on your end-user’s
              networking requirements.
   Service Points – Geographic locations designated by Qwest as to where the ATM Network
    can be accessed and where the ATM Network ports are located. The ATM Service Points
    are listed in the National Exchange Carrier Association (NECA) FCC Tariff 4. (Link blue text
    to: http://www.neca.org/)
   Service Classes are:
     Constant Bit Rate (CBR) - Available with VCCs or VPCs, CBR carries a constant flow of
         information (constant bit rate traffic). CBR includes overheads and is the end-user
         selected upper limit for cell rate traffic on a logical connection. The traffic parameter for a
         CBR PVC is the Peak Cell Rate (PCR). PCR specifies the highest cell rate an end-user
         is provided on a connection. The PCR of a CBR PVC is used to calculate an Equivalent
         Cell Rate (ECR). The sum of all ECR PVCs must be less than the speed of the
         associated port. When cells exceed the peak cell rate, the cells are discarded upon entry
         into the ATM Network.
     Variable Bit Rate real time-(VBRrt) - Variable Bit Rate supports a connection carrying
         information flowing at variable rates. It is available with VCCs or VPC’s. VBRrt is for
         applications requiring restraints on delay and delay variation. Three traffic parameters
         describe the bandwidth characteristics. VBR parameters are the Peak Cell Rate (PCR),
         the Sustained Cell Rate (SCR) and the Maximum Burst Size (MBS). The end-user
         selects the bandwidth characteristics of a VBR PVC by choosing the appropriate SCR
         and MBS, and the PCR will then be set at two times the SCR for VBRrt. The sum of all
         PVC ECRs may equal, but not exceed, the speed of the associated port. VBRrt is not
         available on IMA and T1 ATM ports.
     Variable Bit Rate non real time (VBRnrt) - Available with VCCs or VPC’s, VBRNRT
         carries a variable rate of information (variable bit rate traffic). The PCR of a VBRnrt
         connection may equal but not exceed the speed of the associated port. Maximum Burst
         Speed (MBS) is the maximum numbers of cells that can be sent at the Peak Cell Rate.
         A end-user may send bursts of 100 or 200 cells over a VBR PVC up to the PCR. The
         average cell rate for that PVC must not exceed the chosen SCR.
     Available Bit Rate (ABR)-Supports a connection carrying a specific amount of data. ABR
         parameters include PCR and Minimum Cell Rate (MCR). MCR will automatically be set
         to 10% of the end-user specified PCR. The bandwidth available to the ABR service can
         vary up to PCR, but will not go below MCR. ABR is not for real time applications. It is for
         applications that will tolerate variable bandwidth with a minimum limit that the necessary
         bandwidth cannot fall below. ABR PVCs can only be provisioned as VCCs. ABR is not
         available on IMA and T1 ATM ports.
     Unspecified Bit Rate (UBR)– Is the best effort service designed to support connections
         carrying information at variable rates over VCCs. UBR does not provide traffic related
         service guarantees. The Peak Cell Rate specifies the highest cell rate that will be
         allowed on a connection, but not guaranteed. When cells exceed the Peak Cell Rate, the
         cells are discarded upon entry into the ATM Network. The Peak Cell Rate of a UBR
         logical connection may equal but not exceed the speed of the associated port.
   Cell Transfer – Transfers information between Network Interfaces connected to the ATM
    Network at speed(s) selected by your end-user for VCCs or VPCs. Your end-user must
    select a Service Class for each logical connection. The total speed of Cell Transfer elements
    on the ATM configuration may not exceed the associated Cell Transfer port speed.
   Central Office Connecting Channel (COCC) – Provides the interconnection from the
    multiplexer or other Qwest facility port to an ATM port when your end-user accesses ATM via
    a private line transport facility. This facility will require either multiplexing to be compatible
    with ATM transmission speed or port-to-port connectivity. A COCC may be used to connect a
    SAOAL to a private line transport facility.

Optional Features
Optical Access Link (OAL) Protection is an option, which provides added reliability when ATM is
transported over fiber optics. This feature provides a separate facility path within the same
conduit, cable, sheath, etc. for the protection system between the serving wire center and the
network interface. It is available on ATM 45 Mbps OAL and 155 Mbps OAL. This feature does
not provide diversity into the building. This offering also requires the use of existing facilities.

Optical Access Link (OAL) Access Link Diversity is an option, which provides a standby protect
fiber path, which is routed over facilities separated, from the normal path, by 25 feet or more.
Fiber optic facility separation is from the first utility vault outside the serving wire center to the last
utility vault or hand hole prior to the end-user’s premises. OAL Diversity is subject to availability of
facilities. When facilities are not available, special construction charges may be assessed. It is
available on ATM 45 Mbps OAL and 155 Mbps OAL. This feature does not provide diversity into
the building. This offering also requires the use of existing facilities.
