Syntax and Possible Responses
CIC (Connect Incoming Call)
This command causes the DSU to go on-line. For dial backup units, this
command hangs up the dial backup line and initiates an attempt to re-es-
tablish the main (DDS) line. There are no parameters associated with this
command. Possible indications include VAL, CNX, and CFIxx.
CNL (Configuration Local)
This command is used to pass AT commands to the local modem via the
V.25 bis command processor. This allows the DSU III ARdc to be config-
ured with AT commands via a synchronous interface. The command has
the following format:
CNL [LOCAL PASSWORD;]AT[ONE OR MORE AT COMMANDS]
A local password may not be required depending on the present configu-
ration of the unit. Responses to CNL commands are returned in the data
format currently configured. Possible responses include VAL and INVn.
CNR (Configuration Remote)
This command is used to pass AT commands over the network to the re-
mote DSU via the V.25 bis command processor. This allows a remote DSU
III ARdc to be configured from a synchronous interface. The command's
format is as follows:
CNR [REMOTE PASSWORD;]AT[ONE OR MORE AT COMMANDS]
The remote password may or may not be required depending on the
present configuration of the remote unit. Responses to the CNR com-
mands are returned in the data format currently configured. Possible re-
sponses include VAL and INVn.
