Installation Overview
Installation and configuration of the T1 or E1 Line Card consists of:
❑Obtain the applicable cable; refer to Cabling on page 13 for part numbers.
❑Make sure the BLC is installed and power is supplied to the chassis.
❑Install the card in the BLC.
❑Connect to the T1 or E1 uplink.
❑Configure your unit using the web or TL1 interface. Refer to the SCP card’s online
Help or the 8620 and 8820 Broadband Loop Carrier TL1 Reference for
configuration information.
Be sure to register your warranty at www.paradyne.com/warranty.
Installing T1 and E1 Line Cards
HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive
components from damage due to electrostatic
discharge (ESD) during normal operation. When
performing installation procedures, however,
take proper static control precautions to prevent
damage to equipment. If you are not sure of the
proper static control precautions, contact your
nearest sales or service representative.
A T1 or E1 Line Card can be installed in, removed from, and replaced in a BLC without
disrupting service to the other cards in the chassis.
Procedure
To install the T1 or E1 Line Card:
1. Determine in which slot the unit will be installed. Verify that cards in adjacent slots
have been fastened.
2. Remove the filler plate from the installation slot and store for possible later use.
!

11
3. Holding the T1 or E1 Line Card with the component side facing up (8620 BLC) or
facing right (8820 BLC), insert it into the card guides.
CAUTION:
Do not force the unit into the slot. This could damage the backplane
connectors. If the card does not seat properly, remove the card and reinstall
it. If it still does not seat properly, call your service representative.
4. Slide the unit into the slot until the power and network connectors seat firmly in the
mating connectors on the backplane.
The unit performs a power-on self-test. All of the LEDs turn ON and OFF briefly.
When the self-test is completed successfully, the SYSTEM OK LED begins to
pulse.
If the LED is not pulsing, notify your service representative. See Front Panel LEDs
on page 12.
5. Secure the unit by fastening the screws at each end of the faceplate.

Cabling
The following cables are used with this product:
Model 8995 or Model 8997 using 120 Ohm outputs: Feature Number
8026-F1-001, which terminates in eight 8-pin modular jacks. See Table 1, Feature
Number 8026-F1-001 Pin Assignments, on page 18.
Model 8997 using 75 Ohm outputs: Feature Number 8027-F1-001, which
terminates in 16 BNC jacks. See Table 2, Feature Number 8027-F1-001 Pin
Assignments, on page 19.
Attach the cable to the 50-pin Telco jack that is associated with the slot the T1 or E1 line
card resides in.
Fastening the Cable with Cable Ties
Procedure
To fasten the Telco connector to the chassis using the provided cable ties:
1. Replace the longer captive screw on the cable connector with the #4-40 Phillips
pan-head screw shipped in a plastic bag with the BLC.
2. Locate the connector on the back of the chassis that corresponds with the slot
where you installed the T1 or E1 card. Connectors are labeled 2 and 3 on the 8620
BLC, and 1–18 on the 8820 BLC.
3. Plug the Telco 50-pin cable into the appropriate connector.
4. Thread the provided cable tie through the anchor mount on the end of the connector
where the cable will lie. Tighten the cable tie around the connector and cut off any
excess.

5. Secure the other end of the Telco 50-pin cable by tightening the captive pan-head
screw.
6. If a ferrite choke is included with your T1 or E1 card, install it on the cable as close
as possible to the chassis. If the choke fits loosely on the cable, hold it in place with
a cable tie.
Fastening a Cable with Locking Pivot Brackets
Procedure
To fasten a Telco connector to the chassis with locking pivot brackets:
1. Replace the longer captive screw on the cable connector with the #4-40 Phillips
pan-head screw shipped in a plastic bag with the BLC.
2. Install the locking pivot bracket onto the cable end of the connector using the
captive screw, as illustrated below.
3. Locate the connector on the back of the chassis that corresponds with the slot
where you installed the T1 or E1 card. Connectors are labeled 2 and 3 on the 8620
BLC, and 1–18 on the 8820 BLC.
