Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999
Overview
Introduction
The following section shows how to route the intramodule and
intermodule cabling. You install all cable connections from the
rear of the cabinet inside the I/O cover.
Refer to the following table for a list of cables that are attached
to the backplane.
Cables required
Chapter 11, “Installing the Meridian Mail to PBX interface,”
deals with the network loop and AML cabling.
Intramodule and
intermodule cabling
The intramodule cabling procedure in this chapter describes the
cabling between the backplane and the I/O panel. This includes
the backplane to I/O cables (“Installing I/O-to-backplane
cables” on page 9-9), and backplane to alarm/modem cables
(“Installing the alarm/modem cable” on page 9-9).
The intermodule cabling procedures describe the installation of
the external voice bus (EVB) cable between modules or
columns. The specific EVB cabling that you use depends on the
number of modules and whether there are one or two utility
cards.
The following procedures cover the combinations available:
• “Installing EVB cabling—two modules, one utility card”
on page 9-12
• “Installing EVB cabling—two modules, two utility cards”
on page 9-12
