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.=20
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.
