Call Control Commands

AT%A2=n

Protocol Control. Specifies the protocol you want to use for your ISDN connection.

 

n=0

HDLC-Transparent mode

 

n=2

V.120 rate adaption protocol.

 

n=4

V.110 rate adaption protocol (international version only)

 

n=95

PPP asynchronous to synchronous conversion (International default).

 

n=96

Multilink PPP connection (North American default).

Notes:

Both PPP and Multilink PPP require that a PPP communications stack be installed on your computer.

Both the DIVA T/A and the remote device must be set to the same protocol.

If your workstation is configured as a Windows for Workgroups Remote Access Service (RAS) client, you must configure the V.120 rate adaption protocol on the DIVA T/A workstation and the remote device (RAS Server ISDN adapter).

When using Multilink PPP for incoming calls, only SPAP or PAP authentication are supported.

(Windows NT only) In order to support incoming calls with Windows NT RAS Server, you must enable the parameter “Allow clear text authentication” in the RAS Server setup. Refer to the RAS online help on how to configure this parameter.

This parameter is static. Changes do not take effect until you restart your DIVA T/A.

AT%A4=n

ISDN Communication Speed. Specifies the ISDN communication speed (56 or 64

 

Kbps) at which the DIVA T/A will try to connect to the remote station. The speed only

 

applies to calls initiated by your DIVA T/A.

 

n=0

Connect at 64 Kbps (default).

 

n=1

Connect at 56 Kbps.

 

 

AT%A95=c

Incoming Data Call Answer. Sets how incoming data calls are handled (accepted or

 

rejected).

 

c=E

All incoming data calls can be accepted either by the DIVA T/A (ATS0=1) or by the

 

 

application (default).

 

c=D

All incoming data calls are rejected upon receipt.

 

 

AT&Zn=v

Store Telephone Number. Stores a telephone number v in memory location n. Each

 

number consists of the telephone number (up to 25 characters) and an optional

 

subaddress (up to 20 characters), separated by a period. Valid characters include the

 

digits 0 to 9 as well as *, #, space, hyphen, and parenthesis.

 

Range for n: 0-9, so up to ten telephone numbers may be stored.

 

Note: The maximum number of dialed digits (that is, the numbers 0-9 and symbols #

 

and *) is 20 in North America and 40 for International. If you need to dial a number

 

longer than 25 digits, use the ATDn command (see page 41).

 

 

ATA

Answer Calls. Instructs the DIVA T/A to accept an incoming call.
