2.3.2.5.2 Session Protocol (Layer 5 of B channel)
For the normal sequence of the Session protocol, see "Session" in the B-channel sequence.
A CSE signal is sent at the end of communication in the Session layer. If communication is
suspended, a CSA signal is sent. The cause of a fault can be confirmed by analyzing the
session end parameter information contained in this signal.
