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 trans mitting 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, i n ‘‘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 switch ed,
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 co ntrols 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.
