NTERWORKING WITH THE
TRK-PQ
The Universal Trunk can be made to inter-work with an existing PQ trunk module. This allows the
UTM to be a direct spare for existing installations.
Consider the following diagram:
UTM
Modem
Eliminator
PQ
Node “A”
Node “B”
The configuration is as follows:
trunk type=hdlc phy=v35 modtype=trkt1
The TRK-PQ in Node “B” will have the same number of user channels as the TRK-T1 configured
in the CC of “Node A” for the UTM. However, the user channel offsets will differ. The range for the
TRK-T1 begins at channel 6, and the range for the TRK-PQ begins at channel 10. This
adjustment is made automatically by the UTM and no further configuration is required.
