Installing the network loop

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Using indirect cabling

To install the Meridian Mail to PBX interface using indirect

cabling, use “Network loop cabling between Meridian Mail and

Meridian 1” on page 11-6 as a reference, and follow these steps.

Step Action

2 If you have more than one network loop cable, connect the

cables to Meridian Mail as outlined in the following steps:

a. Connect the first network loop cable to J4 of the first module.

b. Connect the second network loop cable to J5 of the first

module.

c. If the system has more than 48 channels, you need a third

network loop cable and a second utility card. Connect the

third loop to J4 of the module that contains the second utility

card.

d. If the system has more than 72 channels, you need a fourth

network loop cable. Connect this loop to J5 of the module

that contains the second utility card.

e. Enter the loop numbers in the Meridian Mail configuration.

Refer to the chapter on hardware administration in the

System Administration Guide

(NTP 555-7001-30x).

3 Set the switch on the faceplate of the QPC414 network card to

“enable.”

The LEDs remain on.

Step Action

1 Install the I/O panel cable NT8D86AD according to step a

below, based on the loop number you select in steps 1 and 2 of

this procedure.

a. If the loop you select is an even number, install the cable in

the top slot, or J1, of the network card.

b. If the loop you select is an odd number, install the cable in

the bottom slot, or J2, of the network card.

2 If they are not already installed, install the network loop cables

as shown in “Network loop cabling between Meridian Mail and

Meridian 1” on page 11-6 (cable b).

3 Connect the NT8D73 cable between the I/O panels of the

Modular Option EC and Meridian 1.
