Setting other data options for the 7400C

You can usually use the default settings for all other options. However, two exceptions are discussed below.

Selecting data inversion for 64-kbps, HDLC transmissions on restricted facilities

Data inversion is available when you are transmitting at 64 kbps over restricted facilities using HDLC-based protocols. Proceed as follows.

1.If you need compatibility with an ACCUNET MPDM, set DATA INVERSION to ON using the menus and controls as described above, in ‘‘Setting the data speed for the 7400C’’.

2.Otherwise, set DATA INVERSION to OFF.

3.Exit and save changes, as described above, in ‘‘Setting the data speed for the 7400C’’.

Configuring the 7400C for a dedicated private line

The factory default settings assume that the data module connects to a switched, dial-up line. Private lines are permanent, unswitched connections, so they have to be specially configured. Proceed as follows.

1.Set the dialing method to MANUAL, using the menus and controls as described above, in ‘‘Setting the data speed for the 7400C’’.

2.Set the answering mode (ANS) to AUTO.

3.Set the DTR lead to IGNORE.
