Configuring the Modem

Option Set 2—Sync Answering Central Site Without ACU

Changing Default Configuration Settings

Depending on application requirements, you may need to change the following:

•In Option Set 2, the default for network timing is Clock=Internal (AT&X, MODULATION OPTS category). It may be necessary to change the timing to external or loopback, depending on the network clocking source.

•In Option Set 2, the default for ACU Select=None. If you want an ACU to operate the modem, select an ACU and a data format.

•Customize the DTE port as follows:

Set the modem’s DTE rate to match the synchronous DTE’s rate using DTE Rate (AT*DE, TERMINAL OPTS category) (refer to Appendix A for parameter and setting descriptions.)

•The default Answer option is country-specific. Refer to Appendix C to verify that this option is appropriate for your application.

•If the DTE does not provide DTR, the modem will not automatically answer an incoming call. Set DTR=High (AT&D, TERMINAL OPTS category).

Option Set 3—Sync Calls to Central Site, V.25bis ACU

Changing Default Configuration Settings

Depending on application requirements, you may need to change the following:

•In Option Set 3, the default setting for network timing is Clock=Internal (AT&X, MODULATION OPTS). It may be necessary to change the timing to external or loopback, depending on the network clocking source.

•In Option Set 3, the default setting for ACU Select=None. If you want an ACU to operate the modem, select an ACU and a data format.

•Customize the DTE port by selecting this option:

Set the modem’s DTE rate to match the synchronous DTE’s rate using the DTE Rate option (AT*DE, TERMINAL OPTS).

(Refer to Appendix A for parameter and option descriptions.)

•If you plan on using DTR transitions (“DTR Dialing”) to signal the modem to make a call (rather than issuing commands from an ACU), do the following:

1)Set Default Dial=1 (AT*DA, ACU OPTS category).

2)Store a number in memory location 1 (using Enter Phone #, AT&Z, ATAT 9600 T/D? category).

3)Set DTR=108.1 (AT&D, TERMINAL OPTS category). When DTR is raised, the modem will dial the specified call.
