The Supercomm Nortel update included the revelation that the MPE9000 switch/router that was announced last year will finally hit GA by the end of June.  The MPE is expected to be a "big product" (according to VP of Carrier Marketing Jim Dondero) for Nortel within six months, as wireline and wireless operators will begin to rely on it to aggregate ATM, Ethernet, Frame Relay and IP at the edge of their networks.  Nortel has been quoting some pretty impressive VoIP numbers: 55 carrier VoIP customers and 20 out of 35 MSOs that have made VoIP decisions up to now.
