Description of messages
 

Commands with effect on messages
Insofar as the command ATQ1 is not active (messages off), the ISDN terminal adapter will acknowledge input commands and provide messages - regarding incoming calls or the establishment of a connection, for example.

With the default setting ATV1, the ISDN terminal adapter returns messages in plain text (followed by M and a line feed character). With the command ATV0, the messages are returned in short form as a digit (with a leading or concluding M).

V1 V0 Description
OK 0 Command line executed
RING 2 Incoming call
NO CARRIER 3 No connection established, connection ended by exchange of remote station, or inactivity timer elapsed (see also register S154/S155)
ERROR 4 Error during command input
NO DIALTONE 6 No connection to ISDN exchange or own connection is busy
BUSY 7 Requested subscriber or communication paths busy
CALL SENT 252 Dial number complete, call being processed
ALERTING 253 Remote station alerting to call
CONNECTING 254 Call answered by remote station, line protocol being negotiated
 

Caller ID of remote station
The ISDN supplies the caller ID of the incoming call, if this has not been suppressed by the remote station. Register S153 can be used to set whether this number should be displayed together with the RING and/or CONNECT message.
Examples: RING;02416069820

CONNECT;02416069820

CONNECT 64000/ISDN/V120;02416069820

or, if the short form has been set:

2; 2416069820

1;02416069820

221;02416069820

In addition, the target EAZ or target MSN used by the remote station can be displayed. This setting is also made in register S153.

Example: RING;02416069820;MSN
 

CONNECT messages
The CONNECT messages, i.e. the messages confirming the successful establishment of a connection, are influenced by the commands AT-M, AT\V and ATX.
 

NO CARRIER
The cause of the failed connection may also be displayed together with the "NO CARRIER" message (see also register S153).

Example: NO CARRIER;053;016 = normal cancellation of the connection by the remote station.

The following table provides an overview of the possible CONNECT codes in ISDN mode:
