Hello,
Isn' that an killing the hq T1 circuit if you have 90 PVC terminating on one
T1?

To answer this intelligently we'd have to get some more information,
such as:
1. What is the average/typical load per PVC right now?
2. What are your typical peak loads?
3. Would peak times on one PVC necessarily correspond with the peaks
on another PVC?
4. What protocols are you running on these PVCs? SNA? TCP/IP? IPX?
5. What routing protocols are you using, if any?
6. How much growth do you foresee?
7. Are your applications able to handle variable latency and delay?
8. Can they recover well if retransmissions are necessary?
Those are the types of things I would consider when oversubscribing a
circuit. With that said, I'll mention two examples in our network.
The bulk of our traffic between branches is TCP/IP and we tend to
terminate between 7 and 10 PVCs on a single T-1. We also have an
additional PVC to each branch that is solely for SNA traffic, which is
very low volume, and we're using static routing here. In this case, we
have 90 PVCs (coming from 256k and full T-1 circuits) all terminating at
a single T-1 here at headquarters.
At the moment we're barely pushing that second T-1, but due to growth
needs we will be adding a second SNA T-1 in the future.
HTH,
John

If i have a 256k host ckt, how many remote 256k ckts with a cir of 64k
can
i have pointing at the host before i have an over utilization problem?
Will
the cir of the host be a key factor?
Thanks for any and all replies,
Jerry
