About the ATM Line Cards

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:

1

— 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

card. This file may be saved for purposes of disaster recovery by uploading it to
an FTP (File Transfer Protocol) server. A configuration file may be restored by
downloading it from an FTP server.

Use the System - Save and Restore screen to:

 Save (upload) the configuration to an external file using FTP.

 Restore (download) the configuration from an external file using FTP. A

downloaded configuration file remains in the memory of the SCP card until it is
overwritten by another downloaded configuration file, or until the SCP card is
reset to factory defaults.

 Reset the SCP card using factory default configuration settings

 Reset the SCP card using downloaded configuration settings

Procedure

To upload and download configurations:

1. In the Configuration (FTP) box, set the parameters as shown in the following
table.

Configuration (FTP) Parameters

FTP Server IP Address Specify the network address of the FTP server where

the configuration is to be uploaded to or downloaded
from. For example: 137.90.128.10

User Name Specify a user name accepted by the FTP server. For

example: admin

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 Specify a user name accepted by the FTP server. For

example: admin

Password Specify a password accepted by the FTP server. For

example: admnpass

Filename 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."

6. Maintenance Procedures

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
