H-23 Handover
General Description
When speech transmission quality becomes inferior, the D
term
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 D
term
PS series automatically sends HANDOVER request to the PBX.
Service Conditions
1. This service is activated when the D
term
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 D
term
PS user moves to the far end of the radio zone and encounters
inferior transmission quality. In this case, the D
term
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.
