Switched 56 Operation
CRN (Call Request with Number)
When the DSU III ARdc is configured for SW56 operation, the CRN com-
mand causes the DSU to dial the supplied number. The command's for-
mat follows:
CRN [NUMBER TO BE DIALED]
If no number is included in the command, the number stored in dial reg-
ister number 1 is dialed. If no number is provided and no number is stored
in dial register number 1, the DSU III ARdc responds with the call failure
indication CFINS (Call Failure Indication Not Stored).
CRS (Call Request Using Stored Number)
The CRS command causes the DSU III ARdc to dial the number stored in
the specified register. The format of this command is as follows:
CRS [OPTIONAL SPACE][REGISTER NUMBER 1-10]
If this command is issued without the register number parameter, the IN-
VPS (Invalid Parameter Syntax) response is issued. If this command is is-
sued and the register parameter is not in the valid range for dialing
registers, the INVPV (Invalid Parameter Value) response is returned. Oth-
er responses include VAL,CNX, and CFIxx.
DIC (Disregard Incoming Call)
This command causes the V.25 bis processor to return to command mode
even if there is an incoming call pending. This allows local commands to
be issued and incoming calls to be ignored. There are no parameters asso-
ciated with this command. The DSU responds with VAL.
PRN (Program Number)
This command stores the supplied number into the specified register. The
command has the following format:
PRN REGISTER NUMBER;[NUMBER TO BE STORED]
