Dialing in V.120 Mode

Finally, use the ATDn command to make the call (n is the phone number you want to dial). Once

the connection is made, you should see the following connect messages:

CONNECT 115200/V120 56000/LAPD

This message indicates that the connection is made with the following specifications:

• DTE speed of 115.2 Kbps

• Protocol V.120

• Data speed of 56 Kbps

• Error Control LAPD

Making a Bundled Call with V.120

A bundled V.120 connection is initiated at the calling site when ATB20 (B channel protocol V.120)

has been selected and the channel bundling mode has been enabled by an AT&J3 command. The

channel bundling command (AT&J3) must be set on both the calling and receiving sides;

otherwise, a single channel connection is made.

To set up your Model XM128 modem to make a bundled V.120 connection, follow these steps:

Enter ATB20 (set B channel protocol to V.120).

Enter AT&J3 (set the Model XM128 modem to make a bundled call).
