0 1 Use reverse SDLC establishment (SNRM sent by answerer and not

by caller). Mandatory for POS.

1 2 Poll on each SDLC frame. Required by some POS terminals.

ATS92=<n> SDLC Address A (default 0x30)

ATS128 S-register 128 is a read-only register. Reading this register allows to retrieve

information on the current (last) incoming call. It returns a message in the following

format: ;<calling party number>;<destination_address>. If calling party or

destination sub- addresses are present, they are separated by a slash "/" from the

called party number or the destination address. For example, the calling party number

800, calling party sub-address 900, destination address 400, destination sub-address

500 are presented as: ;800/900;400/500.

Bit Value Result

0 1 Enable transmission and reception of empty frames.

1 2 Enable "multimoding", i.e. a trailing byte (modulation tag) in every

frame specifies which modulation has to be used to send this

frame or at which modulation it was received. Valid modulation

tags are 0x27 for V.23 HDX off hook and 0x28 for V.23 HDX on

hook.

2 4 Shield empty frames. This mode enables a tty application to send

and receive empty frames. Since a frame with a length of 1 byte is

invalid in the V.23 SMS and V.23 Caller ID protocol, it is used to

carry the information that an empty frame occurred and which

modulation was detected. The data byte in a real 1 byte frame is

replaced by a unique value 0xff. A single byte frame 0x27

indicates or issues an empty frame in V.23 HDX off hook. A single

byte frame 0x28 indicates or issues an empty frame in V.23 HDX

on hook.

Description

Set Write allows to set coded in accordance with Q.931 cause value to be used

to disconnect this call (for example by ATH/ATZ commands or by DTR drop

operation). The Dialogic

Diva

Media Board provides conversion between

used national dependent values/in band procedures and Q.931.

Read Read after disconnect provides coded in accordance with Q.931 value of

disconnect cause. The Dialogic
