Preparing Coax Distribution Cables - Nortel Passport 15000 Hardware Description

Preparing coax distribution cables

Cards requiring coax connections at the faceplate of FPs or a termination
panel can be provided by Nortel Networks in prefabricated cable assemblies
or must be provided by you. To custom make your own cables for a specific
type of FP, refer to the cable assembly specifications in "Control and function
processors" (page 141). Use the specifications to make your cables. If the FP
description does not list cable assembly parts, you must use the appropriate
prefabricated cable assemblies.
The specialized mini-coax distribution cables for the 4-port DS3 and 12-port
DS3 or E3 cards are available from Nortel Networks in prefabricated
assemblies. These cables have special 8W8 connectors at the FP end to
accommodate dense cabling at the faceplate of the cards. The other end of the
FP cable can be standard coax or mini-coax 8W8.
The PEC of all available FP distribution cables is in the tables
• "Prefabricated FP control port cables for connecting to a sparing panel"
(page 335)
• "Prefabricated 75-ohm cables for connecting FPs to a sparing panel"
(page 336)
• "Prefabricated DS3 or E3 cables connecting FPs to an NTHW52"
(page 336)
Note: There is no control cable between an FP and an NTHW52.
