ITU-T V.25bis Dialing Commands and Response

Connect Incoming Call (CIC)

The CIC command forces the modem to cancel any DIC commands and answer an incoming call. This command is only valid when the DTE issues a DIC command. CIC must be issued within 10 seconds after sending a DIC. CIC is similar to the ATA command.

The CIC command format is CIC.

If CIC is issued within 10 seconds, the modem sends the VAL response to the DTE. If CIC is issued after 10 seconds, INV is returned.

Program Normal (PRN)

The Program Normal (PRN) command allows the DTE to enter and store a telephone number to a specific directory location. PRN is similar to the AT&Z command.

The PRN command format is:

PRNx;n

Where: x is the directory location 1–10. n is the telephone number.

Request List of Stored

Numbers (RLN)

The Request List of Stored Numbers (RLN) command displays telephone numbers stored in the modem’s directory location. If the RLN command is entered without specifying a directory location, then all directory locations and telephone numbers are displayed. If a directory location is entered, then only that telephone number are displayed.

The RLN command format is:

RLN

which displays all directory locations,

or

RLNx

Where: x is a directory location.

List Stored Number

Response (LSN)

LSN is a response to an RLN command issued by the DTE. If a directory location is specified, then the telephone number for that location is displayed. If no directory location is specified, then all telephone numbers stored in memory are displayed.

The LSN response format is:

LSNx;n

Where: x is the directory location. n is the telephone number.

Command Response

A Command Response indicates that the command

entered was a valid or invalid entry. Command Response includes Valid (VAL) and Invalid (INV).

Valid (VAL)

The VAL response indicates that the modem has accepted the V.25bis command issued by the DTE. VAL is similar to the AT result code OK.

Invalid (INV)

The INV response indicates that the modem has received an incorrect V.25bis command from the DTE. INV is similar to the AT result code ERROR.

The INV response format is:

INVxx

Where: xx is

CU command unknown

MS message syntax error

PS parameter syntax error

PV parameter value error
