We run 3 PRI or CT1 on all of our 4000s with no trouble and no
performance issues, but we're not doing anything else with them. No
stacking, no OSPF, RIP, any of that- pretty much the simplest way
possible to run them. Even so, with 4 PRIs going you can tell a
difference, so we just run 3.
Since most of 'em are on CT1 and have no ISDN callers, 72 modems is
the limit anyway so I haven't worried about it, but it does annoy me
that we can't get full use of the boxes on our PRI pops.
I'm confident Ascend will eventually address this somehow, as soon as
the modem wars flame out.
