- What we currently have is quite a few sites doing this:
- ______
- _________ __|____ |
- ----------| |--------[modem]-----| | | Sun 690
- | | | Async| |
- ----------| Call |--------[modem]-----| io | | VME or
- | | | cards| | SBus
- ----------| Dist |--------[modem]-----| | |
- . | | . | | |
- PSTN . | Equip | . | | |
- . | | . | | |
- ----------| |--------[modem]-----| | |
- | | | | |
- ----------| |--------[modem]-----| |_|
- |________| |______|
- upto (say) V32bis
-
- i.e., Multiple PSTN lines coming into a call distributor (same PSTN
- number), which chooses a free modem which is connected to an asynch
- card in the sun, where we can finally start looking at whats coming in
- ... messy.
-
- So, I understand that something like the following may be available:
-
- _________
- | |
- | DSPs | Sun 690
- Exchange | & | VME or
- --------------------------------| Analog | SBus
- E1 (T1) line or equiv | |
- ((PRI)) | Stuff |
- |________|
-
-
- Anybody got any ideas or preferebly experience on this sort of thing?
-
- Or, could I have a Primary rate ISDN line from the exchange, with the
- PTT doing the V32bis etc conversion to digital ... ideas?
-
- PS, I'm in Belgium, so approvals, etc are the next question if anyone
- has detailed knowledge ...
-
-
- Thanks,
