PORTS USED
The Ports Used field is a display-only field. It reflects the number of ports (subscribers) that
are assigned to the particular Bridge.
BRDG TYPE
This is for fur future development, currently only voice is supported.
GAIN
The gain setting allows for a specified gain to be applied to the bridge itself. All subscribers
will be attenuated to the assigned settings. Valid settings are:
When provisioning a bridge, keep in mind that to expand the size of the bridge (max ports) the
bridge must be put into standby mode before making the bridge larger to add a new participant.
Placing an active bridge to stdby mode will not only put the bridge in standby, but will also
automatically place into standby all the participants on the bridge. As this action takes the
bridge out of service, it may be advisable to over-provision a bridge in order to accommodate
for growth. For example, let's say bridge number one will have three participants. Max ports
can therefore be set to three. If however a new participant needs to be added, the bridge will
need to be put into standby mode and then max ports changed to four participants. On the other
hand, if the initial setting for Max ports was four or higher, then the new participant could be
added to the bridge without taking the bridge down first, as this number had already been
engineered for growth. Any change made to the bridge as a whole (Gain, Max ports or the
bridge type) requires that the bridge be taken to the standby status.
