Connecting a Passport 15000 or 20000 to an EdgeLink 100
Connect a Passport 15000 or 20000 to an EdgeLink 100 to enable DS3 FPs to
communicate with a DS1 and DS3 multiplexor.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• Before installing the interface cables and connecting them, the EdgeLink
100 multiplexor must be mounted and the DS3 function processor (FP)
with BNC connectors must already be installed.
• The EdgeLink interfaces to a DS3 function processor (FP) with BNC
connectors in the Passport 15000 or 20000 and to an RJ48 termination
through an access panel. The RJ48 connections are either:
— 64-pin Cinch or wirewrap to an RJ48 T1 access panel with monitor
jacks (part number A0718812)
— 64-pin Cinch or wirewrap to an RJ48 T1 access panel (part number
A0718813)
• The interface cables that connect an EdgeLink 100 to the Passport or the
Ethernet hub of a Preside Multiservice Data Manager are listed in the
table “Interface cables between a Passport 15000 or 20000 and an
EdgeLink 100” (page 303). Two cables are required, one for transmitting
and one for receiving.
• Configuring the software for the EdgeLink can be done before or after the
interface cable is connected. There is no software configuration for the
Passport 15000 or 20000 to interwork with the EdgeLink.
Procedure steps
1 Identify the cable path between the rear of the EdgeLink and the front of
the DS3 card in the switch.
2 Measure the exact distance of the cable path from end to end and record
it. Whether the DS3 interface cable is custom-made or prefabricated,
ensure that the cable is long enough and can be fastened safely along the
path.
3 Route the cable along the path and loosely fasten it with tie-wraps.
