AT&O0 ATD, ATDT and ATDP are the same as ATDB.

AT&O2 ATD, ATDT and ATDP are the same as ATDI.

AT&O3 ATD, ATDT and ATDP are the same as ATDA.

The factory default is AT&O2. This means the TA will select ISDN

data mode when you do not specify which communication mode

to use (i.e. ATD or ATDT).

Placing the Call

To initiate a call, choose the proper communication mode and

configure the mode according to the bearer service (or protocol)

you want to use. Here are some simple commands that will be

useful when placing a call:

Command Description

ATBnn Changes ISDN B channel protocol setting.

ATDL Re-dials the last dialed telephone number.

Incoming Calls

When a call comes in, it will be carried by one of the following

protocols:

• V.120

• HDLC PPP, MPPP or SLIP

• V.110

• X.75

or the call may be initiated by an analog device.

This section will provide some general guidelines for setting up the

device for call answer handling. Be aware that the TA128 will not

automatically answer a call unless S-register S0 is set to a value

greater than 0 (zero). If S-register S0=0, the TA128 will only report

1 2 ... 28 29 30 31 32 33 34 35 36 37 38 ... 172 173
