This document specifies a mechanism to signal Pseudowire (PW) status
messages using a PW associated channel (ACh).  Such a mechanism is
suitable for use where no PW dynamic control plane exits, known as
static PWs, or where a Terminating Provider Edge (T-PE) needs
to send a PW status message directly to a far-end T-PE.  The mechanism
allows PW Operations, Administration, and Maintenance (OAM) message
mapping and PW redundancy to operate on static PWs.  This document
also updates RFC 5885 in the case when Bi-directional Forwarding 
Detection (BFD) is used to convey PW status-signaling information.
