Chapter 6. Configuration

When using stored numbers, V.25 bis accesses stored numbers 1 through 9 used by front panel dialing. See Front Panel Dialing Options.

Auto Answer should be set to Disabled (shown in Figure 6-6) if V.25 bis is in control of answering incoming calls with the CIC/DIC commands, since the other settings for Auto Answer will override V.25 control of the answer func- tion.

V.25 ASYNC Dialing

V.25 bis specifies that the characters should be ASCII, 7 bits, even parity and one stop bit. However, for versatility the ISU 128 allows the data, parity, and stop bits as defined under Data bits. (See Figure 6-7.)
