Dmitri,
From memory you can have 4090 VC'c per interface. You would
get wire speed at the FPC backplane access speed on an M5 is 3.2gbps
full duplex or 6.4gbps in cisco speak!
I've not heard about a limit on VC's per box and would guess that the
interface linit is the one to work on. Within an M5 you have 4 PIC slots
so the maximum number of C-3 ATM interfaces is 8 and OC-12 is 4.

Subject: M5 throughput question
This one is probably for somebody from Juniper:
If I get M5 with 1xGE PIC and 3xdual OC3 PICs, would this run at wire speed?
Assume that OC3's used for "access" and GE is uplink, so all traffic is
between VCs and GigE, no or very little cross-VC traffic.
As well, I need to know hardware/software limits, if there are any:
- How many ATM VCs per OC3 on dual OC3 PIC?
- How many VCs per dual OC3 PIC?
- How many total VCs per M5 box?
- How many interfaces in total one can have?
One more question: on single port GigE PIC, how close its non-blocking
throughput to wire speed?
P.S. VC == PVC in my context. ;)
Thanks,
