H323-STN covers implementation of the maintenance for native mode H.323 endpoints. Native
mode H.323 applications such as Netmeeting or Proshare provide only what is needed to
support the H.323 standard. Communication Manager can invoke very little in the maintenance
area. Communication Manager reports errors as they are detected via the RAS registration and
keep-alive mechanism. Communication Manager PINGs the endpoint via the signaling path, for
example via C-LAN, and via the media path, for example, via Medpro.
The H.323 station type is not attached to a port board. Insertion of the station is not driven by
board insertion, it is driven by successful registration of the endpoint. The H.323 station is
maintained via a set of explicit TCP/IP ping requests and errors reported by the switch software,
which terminates the H.323 signaling portion of each endpoint. H323-STN follows standard
maintenance methodology and supports test, busyout, release and status commands.

Notes:
a. Error Type 1 reports the registration status of the endpoint. If Communication Manager
claims the endpoint is registered and receives keep-alive handshakes from the endpoint,
the test passes. If keep-alive handshaking fails, the test fails. If the user has intentionally
un-registered the station from the server, the station is basically an AWOH station and is no
longer being maintained; no tests will run for this station.
b. Error Type 257 tracks failures of the signaling path PING test. The test attempts to send a
PING packet to the endpoint IP address, as reported during registration. The PING packet
