ITU-T V.25bis Dialing Commands and Responses

F-33821-A2-GB20-40 January 1999

Call Connecting (CNX)

The CNX response informs the DTE that the modem

has connected to the remote modem. CNX is similar to the

AT result code CONNECT.

The CNX response format is CNX.

Call Answer Commands

Call Answer commands disable or enable the modem’s

AutoAnswer function. These commands are issued from

the DTE. Call Answer commands include Incoming Call

(INC), Disregard Incoming Call (DIC) and Connect

Incoming Call (CIC).

Incoming Call (INC)

The INC response informs the DTE that the modem

has detected a ring tone. At this point, the DTE can issue

the DIC command to disable the modem from answering

the call. INC is similar to the AT result code RING.

Disregard Incoming Call (DIC)

The DIC command prevents the modem from

answering an incoming call. This command is only valid

once the DTE receives an incoming call (INC) response

from the modem. A DIC must be issued within 5 seconds

after receiving an INC.

The DIC command format is DIC.

If DIC is issued within 5 seconds, the modem sends the

VAL response to the DTE. If DIC is issued after

5 seconds, INV is returned.

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 is 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.
