Log File Users can configure SNAX/CM to monitor switched network connections and
disconnections. The purpose of a log file is to record activities that occur while
SNAX/CM is running, including status information and error messages.

Server To provide flexibility, SNAX/CM does not dictate what should be done after a
connection is completed. Rather, SNAX/CM notifies a user-written server process of
the completion of a connection management function—such as a call-out or a call-in
request, the existence of a call-in operation, or to validate a call-in calling address or
Exchange Identification (XID).
A server is a process that users write and customize according to what they want it to
do on behalf of a connection. SNAX/CM sends a message to the server process named
in the SNAX/CM CONNECT command and the SNAX/CM ENABLE command
(described in Section 3, “SNAX/CM Commands”) when it detects a change in the
status of a connection or to provide other information. More complete information
about a server process is provided in Section 4, “SNAX/CM Server,” with a detailed
example in Appendix C.
