WE use standard off-the-shelf DSPs (Analog Devices DSP-2181) and widely
compatible V.34 modem source code
>2. Can we selectively Busy out any of the 48 modem lines. Like an Out
>of Service switch.
>
Yes. Busy-out can be accomplished manually or each DSP can make itself
busy-out, if it fails an automatic self test. The auto self test is run at
initial power up, and after the termination of every call.
>3. On a ISDN PRI system, is each of the 48 line a dual purpose line.
>(i.e. user will dial into the same group of phone number for ISDN or
>analog modem service.)
>
Yes. We can handle modem, ISDN or even voice-over-isdn calls on the same
*single* phone number.
>4. How do you handle the ISDN PRI which has only 23 B channel and one D
>Channel. Will I only get 46 user into a PM3 at the same time.
>
The PM3 support 23B + 1D on each PRI line. So you are correct in assuming we
support 46B + 2D on the two port unit.
