2.Allowed User Rate of the Bearer is 32 kbps only.

3.The sub-line of the two-line Dterm PS does not provide this feature (both origination and termination are restricted).

Conditions by PS

1.This feature does not support the CALL FORWARDING - DROPPED CALLS [C-161] / AUTOMATIC ANNOUNCEMENT - DISCONNECTED PS OUT OF ZONE [A-128] / AUTOMATIC ANNOUNCEMENT - CALLED PS OUT OF ZONE [A-129] feature. Accordingly, if a PS is once out of zone, any of these features are not provided.

3.The Call Waiting service is not available for the PS which is just engaged in data communication.

5.CALL FORWARDING - DON’T ANSWER, assigned to a PS, does not function if the PS is just engaged in data communication. Accordingly, if the communication is in progress, the third incoming call (including that by another data terminal) is not forwarded to the target destination (i.e. disconnected after a certain period of time).

6.CALL FORWARDING - ALL CALLS, assigned to a PS, does not function if the PS is just engaged in data communication. Accordingly, if the communication is in progress, the third incoming call (including that by another data terminal) is not forwarded to the target destination (i.e. disconnected).
