Functional Characteristics
The Packet Duplicators provide the functionality to allow broadcast, group and
multicast operation with dispatch calls. Each packet duplicator has the processing
power to make enough duplicate packets for each EBTS in the system. The packet
duplicator is used to replicate voice and data packet for output to multiple MSs in
Dispatch calling and Packet Data networking. If a dispatch call is to a group, the
voice packets from the sender must be duplicated for output to each of sites hosting a
receive unit.
The Packet Duplicators are under operations control of the OMC-R. Alarm and
status information is set to the OMC-R every half-hour. The OMC-R may download
software and control the operation of the PDs using X.25 protocol over V.35 cables
to PD and 10BaseT ethernet to the APDs.
