[c-nsp] PA-POS-1OC3 vs. PA-A3-OC3SMI

[David Aldworth]

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.
