About the ATM Line Cards
ATM Line Cards
The 8955, 8965, 8968, 8975, and 8985 Asynchronous Transfer Mode (ATM) Line
Cards are circuit boards mounted in an 8620 or 8820 Broadband Loop Carrier
(BLC) 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 8975 supports ReachDSL+, providing ADSL or ReachDSL 2.2 on a
port-by-port basis depending on the capabilities of the line and endpoint.
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, 8975, 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.

Disabled - Power management is disabled
Power management refers to the following modes, defined
in the ADSL2 specification:
L2 low power: Power consumption is reduced at the
local unit when there is no traffic. Entry to and exit from
L2 low power mode happens so quickly that it is
undetectable by the user.
L3 low power: The port enters sleep mode during
extended periods of inactivity, saving power at both the
local and remote units.
Power Management State
Enabling
Select the line states that the port may autonomously
switch to on this line:
Idle – L3 low-power mode
Low Power – L2 low power mode
Both – Both L2 and L3 low power modes
None – Power management is disabled
L0 Time Specify the minimum number of seconds allowed between
an exit from the low power (L2) state and the next entry into
the low power state.

Configuring SHDSL Ports (8985)
Use the Configuration - SHDSL Port screen to set parameters for a DSL port on
the 8985 line card.
Procedure
To configure a DSL port:
1. Select a Port from the drop-down list and click on Select. Current values for
the port are displayed.
2. Enter or select the following fields:
3. Click on Apply.
L2 Time Specify the minimum number of seconds allowed between:
An entry into the low power (L2) state and the first
power trim in the low power state
Two consecutive power trims in the low power state
Port Status Select Enabled, Disabled, or Reset from the drop-down list
to determine the status of the port.
Field Description
Field Description
Line Circuit Name Enter a name from 1 to 255 characters long to indicate to
whom the port is assigned. The following values are
reserved and cannot be used: AVAILABLE (port is not
assigned), and FAULTY (port is faulty and can not be
assigned).
SHDSL Line Profile Name Enter the name of a DSL line profile to set rates for the
port.
SHDSL Alarm Profile Name Enter the name of a DSL alarm profile to set alarm
thresholds for the port.
Equivalent Working Length Specify the estimated length of the line. The length is
used to limit transmit rates according to local spectrum
management guidelines.
Port Status Select Enabled, Disabled, or Reset from the drop-down
list to determine the status of the port.

Configuring Line Profiles (8955, 8965, 8975, 8968)
Use the Configuration - Line Profiles screens to define line profiles to be assigned
to ports.
To create a line profile for ReachDSL and ADSL ports:
1. Click on Create New Profile. The ADSL Profile Create screen appears.
2. Enter or select the following fields:
Field Description
Profile Name Specify a name for this line profile.
Latency Select the channel the following rates are effective for:
Fast or Interleaved.
For ADSL, S=1/2 encoding is not supported when
Latency is set to Fast. For ADSL2, S=1/2 is supported in
both modes.
Rate Adaptive Mode Select a rate adaptive mode:
Manual - Manually selected at startup
Init - Automatically selected at startup
Dynamic - Automatically selected at run time
Downstream / Near End Profile
Max Rate (kbps) Enter a maximum rate from 0 to 65535.
Min Rate (kbps) Enter a minimum rate from 0 to 65535.
Max Interleave Delay Select the maximum delay allowed for the interleaved
channel, in milliseconds.
Max Noise Margin Select the maximum additional noise margin.
Min Noise Margin Select the minimum noise margin.
Target Noise Margin Select a target noise margin.
Upstream / Far End Profile
Max Rate (kbps) Enter a maximum rate from 0 to 65535.
Min Rate (kbps) Enter a minimum rate from 0 to 65535.
Max Delay Select the maximum delay allowed for the interleaved
channel, in milliseconds: 1, 4, or 16.
To obtain the fastest rate downstream for ADSL (not
ADSL2) endpoints that support S=1/2 encoding, set
Latency to Interleaved and Max Delay to 1 ms.
Max Noise Margin Select the maximum additional noise margin.
Min Noise Margin Select the minimum noise margin.
Target Noise Margin Select a target noise margin.

Creating Line Profiles for Ports (8985)
Procedure
To create a line profile for SHDSL ports:
1. Click on Create New Profile. The SHDSL Profile Create screen appears.
2. Enter or select the following fields:
3. Click on Apply.
Field Description
Profile Name Specify a name for this line profile.
Max Rate Enter a maximum rate from 192 to 2304 kbps.
Min Rate Enter a minimum rate from 192 to 2304 kbps.
Mode Select the regional setting supported, as specified by
ITU-T G.991.2:
Annex A
Annex B
Both
Remote Management Select Enable or Disable from the drop-down list to
determine whether remote management is supported for
the network element this profile is assigned to.
Reference Clock Select the timing source from the drop-down list:
System – Clocking is provided by the backplane. (The
backplane clock is configured on the Configuration -
System - Clocking screen.)
Local – Clocking is provided by an onboard oscillator.
Target Margin Enter a target noise margin from 2–15 dBm, or None.
Interface Select an interface from the drop-down list:
Wire Pair 1 – The profile applies to Wire Pair 1.
Wire Pair 2 – The profile applies to Wire Pair 2.
Select Wire Pair 1 if this profile is to be used for ports that
use only one wire pair.
