I'm wondering if there is a way to tell in HyperAccess or by telneting to the rack to see if a user is using mppp. Is there a way to tell if an ISDN user is using two modems?
Thanks,

I've got a TCR with 2 HyperDSPs working fine connected to PRIs. I've had to add another DSP because of expansion. I've got the card in the TCR and have copied the configuration from one DSP to the new DSP, ie trunk settings, swith type, etc. My users are getting unusual high tones at handshake and then the connection drops. I've talked with several 3COM technicians who have said the card is setup correctly. I've had the PRI checked by the telco technician twice and they say that the PRI is good. The 3COM technician had me look at the errors on the span and they were incredibly high for the new card. The telco say that when he hookd his "t-bird" to it (whatever that is) he doesn't get any errors. Anybody have any ideas on how to troubleshoot this? There is a lot of finger-pointing going on.
Thanks,

If you're getting a high error rate ensure you've got all your T1/PRI line
settings correct; ie: line coding, framing, and timing. It's entirely
possible that the telco delivered one line provisioned one way and another
in a completely different manner. Try to get the telco to verify all that
info. Line coding is either B8ZS or AMI, framing is either ESF or D4, and
timing source can be supplied by the telco (line) or you (internal).
Good luck,
Charles

Actually, there's a little more that's good: V.92 allows 3 options for client for call waiting - Modem-On-Hold (which you need to have enabled as well), HangUp, and Ignore. I can't tell you how many people have asked me how to make their modems hang up when they have a call waiting. Instead, they're on line, probably retraining to boot.
The proposed V.250 commands I just put up at http://808hi.com/56k/v92c.htm show you the increments you can allow for modem-on-hold.
Could be a good thing.
V.44 should help as well.... better throughput ultimately = shorter sessions...?
Aloha,
Richard
