Connect a CP modem cable between the modem and a Passport switch after
you have configured the modem software, to enable a remote user to dial up
to the Passport and have a local operator connection.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• Do not use the DCE V.24 cable assembly (PEC NTBP25) to connect a
modem to port 1 of the CP in a Passport. The connector on the faceplate
is for a customized DB-9 cable. Ensure the modem cable complies with
the specifications in "Procedure job aid" (page 300).
1 At the front of the Passport where the cards plug in, locate the CP in slot
0 or 1.
2 Locate the 9-pin D-sub connection on the faceplate labeled port 1.
3 Plug the 9-pin connector on the cable into the connector on the faceplate.
4 Route the other end of the cable up through the cable organizer, over the
top, and down to the rear of the Passport shelf. Leave the remainder of
the cable hanging loosely.
5 Place the modem at the rear of the Passport shelf. Find a way to fasten it
to the cable guide on the side that is nearest to where the cable passes
over the top of the shelf.
6 Plug the modem into its own power outlet. Follow the instructions provided
by the manufacturer of the modem.
7 Connect the remaining end of the custom cable into the modem.
Assemble the custom modem cable using:
• a V.24 serial interface cable; to determine the length, trace the cable path
from either CP at the front of the Passport up through the cable organizer,
over the top, and down to the rear of the shelf where the modem can be
located inside the cabinet and optionally fastened to the cable
