4.1.5 Standby-Sync Port
A 9-pin female connector is used on the OSMs/ESMs with 8 ports to connect the
ITP XP standard cable 9/9 for the redundant standby coupling. The casing of the
connector is electrically connected to the casing of the OSM/ESM.
The OSM TP22 and ESM TP40 do not have a standby-sync port.
A screw locking mechanism holds the connectors firmly in place.
