ISU 2x64 Dual Port ISDN Service Unit User Manual 61200051L1-1D
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.)
