You cannot terminate OC-48 directly into the Versalar 15k. Its OC-12 and OC-12c.
I'm not finding my notes as to whether there is an Oc-12 card on the access side.
I recall an OC-3 access card (note, I refer to channelized not concatenated).
Certainly DS-3. 
I have been told that it has been tested with 256 BGP peers in a mix of internal and external.

V15k was built for the edge of the network, but has been used for core by some because
there isn't anything bigger from Nortel until V25k release. V25k will eventually take OC-48
ATM. I believe it starts with WDM.

If you do not find the answers you need, I can point you at someone inside Nortel
Networks who has the answers and probably customer references.
