MakeBusyViaDTR: Disable

Nxt Disable Enable

Make Busy Via DTR. Determines if the modem goes off-hook when DTR is Off. Enable this setting if the DTE normally keeps DTR ON and turns DTR Off when the DTE cannot accept a call.

NOTE: This configuration option should only be used when the modem is located behind a user's Private Branch Exchange (PBX). For 3811Plus modems, the MakeBusy Network Interface Modules (NIMs) must be installed on the COMSPHERE 3000 Series Carrier. Refer to the COMSPHERE 3000 Series Carrier, Installation Manual.

The factory default is Disable.

AT command equivalent is S-register S69=n.

DTR Auto Redial

Nxt Dir 1 Dirs1-2 Dirs 1-3 Dirs 1-4 Dirs 1-5 Dirs 1-6 Dirs 1-7 Dirs 1-8 Dirs 1-9 Dirs 1-10

DTR Auto Redial. Defines the number of directory locations the modem may access when prior dialing attempts fail. For example, the selection Dirs1-10 means that all ten directory locations may be tied. The default is directory location 1 only.

DTR Auto Redial represents the same internal setting as that accessed with the Auto Redial configuration option in the Leased-Line group. However, DTR Auto Redial is in effect (and can be accessed) only if the DTE Dialer Type is DTR=Dirs.

Dir 1 ± The modem will use only directory location 1 for automatic dial backups.

Dirs 1-2± The modem will use directory location 2 in the event of call failure using directory location 1. Dirs 1-3± The modem will use directory location 3 in the event of call failure using the preceding entries.

Dirs 1-10± The modem will use directory location 10 in the event of call failure using the preceding entries.

AT command equivalent is S37=n.

MI/MIC Dialing: Disable

End Disable Enable

MI/MIC Dialing. Also known as D-Lead signaling, is required by some PBX systems, older data phones, and security callback systems. It forces the modem into the originate handshake after first dialing a call.

Disable ± Modem ignores activity on the MI/MIC contacts.

Enable ± (3811Plus only.) When the MI/MIC contacts are closed, the modem goes into talk mode; when the contacts are open, the modem goes into data mode. A 26-pin D-Lead control connector located on the rear of the 3000 Series Carrier is used for MI/MIC Dialing for 3811Plus modems.

The factory default is Disable.

AT command equivalent is S-register S83=n.
