The ML series card are basically 3550 switches with 2 POS interfaces.
You cannot terminate a T1 on them. You can link them together by
attaching STS-n to the POS interfaces to make a packet ring over the
SONET. What he needs is a cost effective way to terminate the HDLC
frames from 1100 DS-1s. The Seranoa WANPort (www.seranoa.com) does
that. You could use the 454 with DS3-12 cards to eat up a bunch of M13
generated ChDS3 and feed them out an OC-12 port into a ChOC-12 card on
a 7600, GSR or 10k. The 15454-DS3-12 card can only handle STS sized
chunks, if you need VT grooming inside the 454 chassis you'll need to
use the DS3XM-6 card.
