Chapter 6. Configuration

The ISU supports the following V.25 bis commands to control automatic calling and answering:

CRN . . . . . . . . . . . . . . . . . . . . Call Request (number in command)

CRS . . . . . . . . . . . . . . . . . . . . . Call Request (using stored number)

PRN . . . . . . . . . . . . . . . . . . . . Program Stored Number

RLN . . . . . . . . . . . . . . . . . . . . List Stored Number

CIC . . . . . . . . . . . . . . . . . . . . . Connect Incoming Call

DIC . . . . . . . . . . . . . . . . . . . . . Disconnect Incoming Call

When using stored numbers, V.25 bis accesses stored numbers 1 through 9 used by front panel dialing. See Front Panel Dialing Options on page 63.

The following configuration (see Figure 6-6) for Auto answer should be selected 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 function.

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 2x64 allows the data bits, parity, and stop bits as defined under Data Format. (See Figure 6-7.)
