Cisco has a new set of "VWIC" WIC modules that will do the job.

Subject: Re: Channelized T1's & Remote Access Routers
The feature you're looking for is called drop and insert. I don't think
the channelized T1 modules for the Cisco 3640 will do it. I don't know
about the AS5300 off the top of my head, but Cisco's web site should say.
I was doing this with an Ascend Max 6000, and it worked. I wouldn't
recommend the Maxes, though, since unless something has changed in the
last five months, we were never able to find a software version for it
that supported v.90 and would stay up for more than a few weeks without
needing to be rebooted. Other dial-up terminal servers should be able to
handle this too. Look for "drop and insert" in the specs.
Inet-access is probably a better list for this discussion than nanog.
