Service Flow

Subscriber A has registered the DDI service and subscriber

B is in a PBX group.

Step 1: Subscriber A calls subscriber B. Subscriber B is alerted and

subscriber A hears the ring back tone.

Step 2: Subscriber B picks up the handset. Subscribers A and B are

talking.

Step 3: Either subscriber A or subscriber B hangs up. The call ends.

If subscriber A does not register the DDI service, the operator of the

PBX group to which subscriber B belongs is alerted and subscriber Ahears the ring back tone.

This service can be used without registration

if the subscriber has the rights to use the

service.

To cancel the DDI service, run MOD BRA

with Supplementary serviceset to Direct

dialling in.

Registration and Cancellation

Application Limitations

The DDI service applies only to ISDN subscribers.
