The vast installed base of OC12 and OC48 muxes (Lucent, Fujitsu) do not. This is true in the long-haul...but not in metro platforms. Cisco's 15454, Nortel's OPTerra 3500 are just 2 out of the many multi-service platforms that range from DS1-OC48 in the same box. But I guess each vendor has "the right way to do things" or so they all think. Anyway...this thread is way off topic...I'm going to try to restrain myself. Sorry for the OT post again.
