TBOS Alarm/Status Point Management
Remote RMX-3200 supports 512 TBOS alarm/status points and 512 TBOS control
points per asynchronous serial interface. TBOS alarm/status points are arranged in
eight bit characters, with a TBOS display comprising a group of 8 characters. Each
TBOS-enabled port supports up to 8 displays for a total of up to 512 alarm/status
points. By default, all displays and points on a TBOS port are disabled and are not
polled.
Once a display is enabled, the TBOS subsystem sequentially polls each enabled
character in the display to find out which alarm/status points are enabled. Each
character is queried twice in succession. If the responses to both queries are not
identical, the response is considered invalid. Responses are analyzed to determine if
any of the character’s eight status points have changed state. When a point state
change is detected, a mediation event is generated.
TBOS Control Point Management
Users can configure an action to cause the TBOS subsystem to send a TBOS
command to activate or deactivate a specific control point on a TBOS Network
Element (NE). TBOS commands use three bytes: The first identifies the display and
type of operation (latch on, latch off, or momentary); the second identifies the point (1
to 64); and the third contains an execute operation code. The TBOS NE must
immediately echo each character back to indicate that the operation is being
accepted.
