CJ,

I'm going to agree with those that proposed the external OC3 mux.  It 
really is your best bet.  It also gives you the most long-term options. 
  The Adtran OPTI-3 mux will be able to do the heavy lifting on your OC3.

It supports protection too so you can insist that your provider give you 
a protected OC3 if they want to cram an OC3 down your throat.  With that 
mux you have the option to terminating the CC DS3 and channelized DS3 on 
different devices if you so choose (now or in the future).  That really 
is the best option.

The other thing you might consider is replacing or adding to your router 
collection and getting an ASR (or other router that supports SPAs like 
the 7600).  The ASR has a channelized OC3 module that could do what you 
want.  List on the dual channelized DS3 SPA is $30k.  List on the 
channelized OC3 is only $36k.  The channelized quad-DS3 is $60k.  The 
OC3 is a good deal on that platform if you don't mind buying the 
external OC3 mux.  That's what I'll be doing in the future.  I'm 
replacing my Widebanks with Adtran MX2820 M13s.  Then I'm going to mux 
them with the OPTI-3 and terminate it in an ASR with the channelized OC3 
SPA.
