Gino,
"Pseudowire" in Cisco world is used as a generic term, to describe a
'virtual direct connection'.
There's a very specific meaning too. Pseudowire is circuit emulation
over a packet network. "PWE3" (edge to edge emulation) is a standard
for emulating lower-layer services, such as TDM and ATM, across
Ethernet or IP. It's widely used in Carrier Ethernet devices,
especially as a way to provide incidental numbers of TDM circuits
(usually DS1s) across a non-TDM network. Thus a SONET network might
be retired in favor of Ethernet, if there's a need for only a little
TDM. Cisco and many others support it. But I don't think it gets
down into the "plastic shell" product class characteristic of WISP gear.
