About the ATM Line Cards
1
ATM Line Cards
The 8955, 8965, 8968, and 8985 Asynchronous Transfer Mode (ATM) Line Cards
are circuit boards mounted in an 8620 or 8820 Broadband Access Concentrator
(BAC) and used to transport ATM cells at high speeds over a single twisted-pair
connection or, optionally, two twisted-pair connections (8985 only).
„
Model 8955 supports ReachDSL. It automatically adjusts to the highest rate
the loop can support, from 32 to 2176 kbps. It has 24 ports.
„
Models 8965 and 8968 support Asymmetric Digital Subscriber Line (ADSL).
They can be set to adapt to the line conditions at startup, or set to the following
fixed rates depending on line code:
— G.lite: 64 to 3008 kbps downstream and 32 to 512 kbps upstream.
— G.dmt, ANSI T1.413, ADSL2, and ADSL2+: 32 to 8000 kbps downstream
and 32 to 832 kbps upstream.
— ADSL2: 32 to 16000 kbps downstream and 32 to 1056 kbps upstream.
— ADSL2+: 32 to 29000 kbps downstream and 32 to 2200 kbps upstream.
The Model 8965 has 24 ports and the Model 8968 has 48 ports.
„
Model 8985 supports Single-pair High-speed Digital Subscriber Line
(SHDSL). It can be set to adapt to the line conditions at startup, or set to a
fixed line rate from 192 to 2304 kbps (or 384 to 4608 kbps with two wire pairs).
It has 24 ports.
The 8955, 8965, 8968, and 8985 line cards are configured and managed using the
Shelf Concentration and Processing (SCP) card.
Part of Paradyne’s Hotwire Connected™ program, the cards interoperate with
third-party DSL endpoints providing end users with the ability to select the best
equipment to fit their application. The line cards also integrate support for multiple
DSL services on a single card.

Configuring Cross Connections
Use the Configuration - Cross Connect screen to establish or delete Virtual
Channel Connections (VCCs) by port or by slot. Connections may be established
between any combination of:
„
„
„
Subtended ports
DSL ports
Network interface (uplink)
Default Mappings
A DSL port’s data VPI/VCI is always 0,35.
Default VC mappings to the SCP card for data service may be determined so:
„
„
VPI is 2 for ports 1–24 and 3 for ports 25–48
VCI is (Slot * 24) + (Port number up to 24) + 7
Port numbers 25 through 48 are reduced (by 24) to 1 through 24, respectively, in
calculating VCI. So the VCI for Slot 3, Port 1 is the same as the VCI for Slot 3,
Port 25:
Slot 3, Port 1: 3*24 + 1 + 7 = 80
Slot 3, Port 25: 3*24 + 25 – 24 + 7 = 80
Adding a Port-to-Port Cross Connection

Configuring ATM Ports
Use the Configuration - ATM Port screen to associate a DSL port or the T1/E1 port
with an ATM segment location. ATM segment location ID is a 16-octet field that
identifies this ATM interface for OAM F5 loopbacks. When a segment F5 OAM
loopback cell is received, the destination segment location in the cell is compared
to the segment location ID for the port. If the destination location ID matches the
location ID or is all ones, the cell is looped back to the source. If there is not a
match, the cell passes through the card.
Procedure
To associate a port with an ATM segment location:
1. Select a Slot and Port from the drop-down lists, and click on Select.
2. Enter an ATM Segment Location ID. The value must be 32 hexadecimal
characters or ALLONES. Allowed values are restricted per ITU-T1.610 as
follows:
— The first byte must be 01, 02, 03, FF or 6A.
— If the first octet is FF, then octets 2–16 must also be FF.
— If the first octet is 6A, then octets 2–16 must also be 6A.

Downloading and Switching Firmware
Use the System - Firmware screen to upgrade firmware or switch versions of
firmware in the chassis.
The SCP card has two banks of firmware: the running firmware and alternate
firmware. When firmware is downloaded, it is downloaded to the alternate
firmware bank. Switching firmware versions changes the running firmware to the
dormant (alternate) firmware, and the alternate firmware to the active (running)
firmware.
Downloading Firmware
Procedure
To download new firmware from an FTP server to the SCP card:
1. Enter or select the appropriate parameters in the Firmware Download box as
shown in the following table.
Firmware Download Parameters
FTP Server IP Address
Specify the network address of the FTP server where
the firmware is to be downloaded from. For example:
137.90.128.10
User Name
Password
Filename
Specify a user name accepted by the FTP server. For
example: admin
Specify a password accepted by the FTP server. For
example: admnpass
Specify the name or pathname of the firmware file. For
example: /scp_030145.fpi
2. Click on Download. The firmware is downloaded. A Firmware Download
Status frame is displayed showing the filename, server address, number of
bytes transferred, and the Transfer Status.
When the download is complete, Transfer Status changes to "Transfer
completed successfully."

Switching Firmware
Procedure
To switch between the firmware currently running and alternate firmware stored in
the unit:
1. Verify that the Running Firmware and Alternate Firmware displayed in the
Firmware box are different versions.
2. Click on the Switch button. The unit is reset and:
— The Running Firmware becomes the alternate firmware
— The Alternate Firmware becomes the running firmware
3. Delete the cache used by your web browser before logging into the SCP card:
— With Internet Explorer, select Tools -> Internet Options. On the General
tab, in the Temporary Internet Files box, click on Delete Files.
— With Netscape, select Edit -> Preferences. Click on Advanced, then click
on Cache. On the Cache page, click on Clear Memory Cache, then click
on Clear Disk Cache.
4. If you upgrade an 8965 or 8968 line card from a firmware level prior to 3.01.06,
Restarting the Line Card
The System - Restart screen allows you to reset a line card or SCP card and clear
its statistics.
This is a software reset that does not power down the unit. However, all links are
dropped, and the restarted line card retrains with its DSL endpoint.
Procedure
To restart a card:
1. Select a Slot from the drop-down list and click on Select.
2. Click on the Restart button.
