I work for the US Government and we have recently called out a PRI for one of our locations overseas and I was wondering if someone could tell me how the PRI gets broken out into 64K channels. Will a mulitplexer be required or does the terminal adapter break out the channels for you???
There is no extra customer-side equipment needed for this, the difference is in the signalling with the provider. Your provider must be able to provide this service, it will not work on an ISDN30 that is configured for PSTN/ISDN dialing in/out. As you will notice, the controller config is different. The channels are split in to serial lines in the software. This is specified in the controller desciption. Example:
controller E1 0/0
channel-group 3 timeslots 4
channel-group 4 timeslots 8-9
channel-group 5 timeslots 14
description 2 MB Channel
When you create a channel-group, a serial interface pops up in the configuration.
Great answer....However I don't think it solves my paticular problem. I can't plug the PRI directly into the router. I have to break each 64K channel out separately into a serial encryption device which connects to my router. This is why I was asking about a multiplexer. Any thoughts...
