General Description

When speech transmission quality becomes inferior, the Dterm PS re-originates a call automatically and seizes another radio channel, making the PBX hand the call over to another zone transceiver to maintain speech quality.

Operating Procedure

No manual operation is required. The Dterm PS series automatically sends HANDOVER request to the PBX.

Service Conditions

1.This service is activated when the Dterm PS is engaged in communication.

2.The communication may be interrupted when the PBX hands the call over. The interruption is usually within a second, to a maximum of ten seconds.

3.This service is also available when a Dterm PS user moves to the far end of the radio zone and encounters inferior transmission quality. In this case, the Dterm PS searches for the radio zone with the stronger

electric field, and if the radio zone is found, HANDOVER is activated and the conversation is continued in that zone. If there is no idle channel in the new radio zone, the conversation is continued in the current zone until the communication becomes unavailable, and AUTOMATIC RELEASE - OUT OF CELL CALLS is activated.

4.PS AUTHENTICATION is activated every time this service is activated.

5.In a FCCS network, inter-node HANDOVER is available within the identical PCN.
