A pseudowire service provides pseudowire connectivity between pseudowire endpoints. A pseudowire endpoint is a TDM DS1/E1 interface on a pseudowire-capable module.

The incoming bitstream on the TDM interface is encapsulated within Ethernet frames and transported across the network as regular Ethernet traffic. At the egress, the bitstream is extracted from the Ethernet frames and transmitted out the DS1/E1 interface at the far end.

PSM can be used to manage pseudowire services on the BTI810.
