- We're considering bringing in a bunch of phone lines to be used for a
- modem pool in on T-1 circuite, rather than individual analog circuits.
- The idea is to eliminate as much analog junk between the modems and
- CO, as well as making management of the lines a bit easier to deal
- with.
-
- The usual approach to this sort of thing is to plug your T-1 line into
- a D4 channel bank, giving you 24 two-wire voice circuits. Now, it
- certainly seems a shame to take all these perfectly good digitized
- audio samples, turn them into an analog signal, only to be digitized
- again by an A/D converted hooked to the DSP in a V.32bis modem.
-
- I'm looking for vendors that build V.32/V.32bis modem banks that can
- be directly connected to the T-1 circuit bearing the 24 voice
- channels. Does anyone have experience with such a thing?
