2-73920-A2-GH30-40 October 1998

Leased-Line Network Connection

Use the following steps to connect the leased-line network interface:

1. Insert the 8-position, 8-conductor modular plug into the jack labeled LEASED

(Figure 2-1 or 2-2).

2. Insert the other end of the modular cord into the leased-line network interface.

3. If the Model 3920Plus has a backup line, follow the steps listed in the Dial Backup

Connection section.

Dial Network Connection

The telephone company provides the line termination jacks for the permissive service you request.

Advance coordination with the telephone company is suggested when connecting the modem to

telephone dial lines (PSTN).

In the Permissive mode, the modem’s transmit output level is fixed at –9 dBm. The telephone

company assumes that the line loss is 3 dB and no compensation is provided for additional losses.

A Permissive mode telephone line is usually terminated with a USOC RJ11C jack.

Leased Backup Connection

Use the following steps to connect the modem to the 2-wire leased backup network interface:

1. Insert the 8-position, 8-conductor modular plug into the jack labeled DIAL

(Figure 2-1 or 2-2).

2. Insert the other end of the modular cord into the leased-line network interface.

Dial Backup Connection

Use the following steps to connect the modem to the dial network interface:

1. Insert the 6-position, 4-conductor modular plug into the jack labeled DIAL

(Figure 2-1 or 2-2).

2. Insert the other end of the modular cord into the dial network interface.

Network Management System Connection

Use the following steps to connect the modem to the network management system (NMS):

1. Insert the sub-miniature, 4-conductor modular plug of the 3600 Hubbing Device into the

jack labeled NMS (Figure 2-1 or 2-2). Refer to the 3600 Hubbing Device, Feature Number

3600-F3-300, Installation Instructions for a description of the 3600 Hubbing Device.

Installation for the 3920Plus is the same as for the 3610 DSU.

2. Connect the 3600 Hubbing Device to the NMS (Figure G-5 in Appendix G).
