Sharing PSTN Resources
A stand-alone SmarTrunk II system requires that PSTN/PABX lines be con-
nected directly to specific controllers. This means that only those controllers
with lines connected can be used for PSTN/PABX calls.
When using the ST-510 Switch, PSTN/PABX lines are connected to the switch
rather than individual controllers, so that PSTN/PABX resources can be shared
by any controller in the network. It may also be possible to reduce long
distance charges by routing long distance calls to a target city through the
network.
Larger Call Records Database
With the ST-510, call records are stored on the hard disk of the main CPU
where they can be maintained indefinitely, depending on disk capacity. This
eliminates the need to frequently download these records from the individual
ST-852/853 controllers.
More users profiles
Because users data is stored on the hard disk of each ST-510 in the network,
the number of users profiles is virtually unlimited. The new users profiles are
also enhanced because of the many additional parameters for each users.
Larger users Capacity
A normal SmarTrunk II system is limited to 4,096 users per site. With the ST-
510, up to 320,000 users can be activated on the network.
