Appendix C C-15
Configuring the Remote Support Modem
Configuring Individual Modems
For V.22bis auto-answer, internal jumper DSR must be set so that DSR follows OH. The
factory default is for DSR to follow CD. This is different from the Support Link where the
factory default was for DSR to follow OH. There does not seem to be an AT command that
does this.
V.25bis dialing parameters:
