TSAT 3000 - PORT_SWITCH_TIMEOUT [N]

TSAT 3000 - Telemetry and data transfer via SATellite
TSAT 3000 Configuration Parameter Description, January 2013 Page 23 of 124
3.1.16 PORT_SWITCH_TIMEOUT [n]
Default 0, Range 0…3600
Ver <= 31.7.1:
Not Implemented.
HUB Ver >= 31.8.0
Not Used
RT Ver >= 31.8.0
The “Switch Timeout” facility is controlled by this MIB parameter, and is enabled for
STREAM,
ADAPTER and NETWORK ports when this value is different to zero, and the RT is part of a
Redundant satellite network (i.e.
PHL_TX_HUB_FREQUENCY_BKUP is different to zero).
In this case, a timer is started (i.e.
PORT_SWITCH_TIMEOUT [seconds]) each time data is sent
to
the PORT (from TSAT modem to locally connected equipment).
RT will switch to the other HUB (Main- or Backup-HUB) when timer expires.
This facility will correct a problem that could occur when the Application (at HUB side) only
have access to Application-Equipment (at RT side) via one
of the HUBs in a Redundant
satellite network. This malfunction could have been caused by routing problems, or general
equipment failure, at the HUB side(s).
Enabling this facility will cause the RT to switch between Main- and Backup-HUB until
Application communication is working ok.
Usage is dependent on
PORT_TYPE [n].
