So the below config will get break the OC3 into DS3's but to get from
each DS3 to the individual DS1's I need to add a TransMux card into
the chassis. This would negate the need for the DS3's to be plugged
into a VXR with a pa-mc-t3 card. Would one TransMux card be
sufficient? What about for an OC12?

If you want to do 1:1 DS3, that'd work. If you want to rearrange
individual DS1s, you need a TransMux card

A vendor suggested the following configuration:
15454 Chassis and Fan
Dual TCC+ cards
Dual Cross Connect Cards
1 DS3 card (12 DS3s)
1 DS3 backplane (24 DS3 Backplane)
1 OC3 card (4 port OC3) 1310 fiber only
Seems like it is a big mux and I would still need to punch into a pa-
mc-t3 or some such in order manage things at the T1 level.

I'm pretty sure this is how it would be. You would need a frame-

in front of the POS interface, it isn't a CHOC interface. The ATM
would need
an ATM switch in front of it to support ATM T1's. There is a PA-
MC-2T3+ that
is channelized for the 7200. With this you could put a MUX
in front
of it.

We are looking for a fully channelized OC3 interface for a
Cisco 7200
VXR. Something that we can break individual T1's off of. In
researching this there are two routes: PA-POS-1OC3 or PA-A3-OC3SMI.
The first is SONET and the second is ATM.
Other than price what is the difference? Which is needed?
Thanks for any and all advice.
David
