Do you have the MAX 1600 or the MAX 400X ? In the latter case, the T1 you will use is the 4th one on the chassis. In the 1600 you do need the T1 slot card... >Second, if we got a PBX that supported a PRI interface, can we then >use the Drop-and-Insert capability and not use the PRI<->T1 conversion >at all? No. D&I is strictly T1/T1, no PRI. >Assuming we get a PBX that can support a DS1 interface only (not PRI), and >we could use the PRI<->T1 conversion, how does the second T1 behave... >That is, it comes out of the Max on the 2nd line through the CSU, so do >we need a CSU on the PBX end? Typically no, you connect to a DSX card on the PBX - assuming we are not trying to drive the T1 signal more than about 650 feet cable length ? >If we can use the PRI<->T1 conversion, does it pass Caller-ID information >onto the PBX via the T1 voice channels? The manual vaguely says that >Caller-ID information is not passed on but is not totally clear on it, it >does say that DNIS is passed on is that true? No caller-ID. Yes it passes on DNIS/DID information...
