Single PRI Unit
When a single PRI unit is being used you similarly need to assign a Unit ID, Port number and Channel
Number to a Trunk Number in MyCalls. Unless multiple units are being used, the unit ID will always
be 1. As there is only one port on the PRI units, it is always referred to as port 0.
NOTE: With Primary Rate ISDN the Channel Numbers do not run sequentially from 1-30 as usually
expected. This is an industry standard and not specific to NEC Infrontia equipment. The reason for
this is that on Primary Rate there are 30 B channels and 2 D channels. B Channels are used for calls
only. D channels are used for signalling only. The two D Channels that are used with Primary Rate
ISDN are channels 16 and 32. These ISDN channels relate are not visable in the configuration of the
SV8100. The diagram on the next page shows the full relation between SV8100 Trunk and ISDN
Channel Numbers.
In MyCalls go to the Configure / Telephone System / Edit PBX and edit the Call Recorder
configuration.
Click the Assign button next to trunk 1 and assign Unit ID to port 0 and channel 1.
