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 4).
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 4).
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) interface:
1. Insert the sub-miniature, 4-conductor modular plug of the 3600 Hubbing Device into the jack labeled
NMS (Figure 4). Refer to Document No, 3610-A2-GZ45, 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 network management system (Figure G-5 in Appendix G of
Document No. 3920-A2-GH30).
