Trunk connection management
You can manage trunk connections to the host PBX in several ways:
!
Put the Remote Gateway 9150 unit into offline mode, so that it cannot place
or receive calls through the host PBX when operating in PSTN mode.
!
Define call duration and idle timers, if the trunk connection is defined as
on-demand.
!
Define minimum and maximum bandwidth allocation settings.
!
Use QoS Transitioning Technology.
QoS Transitioning Technology
On IP networks, traffic congestion or delays can occur that result in poor voice
quality or lost connections. The RLC can be configured to transition call
processing from the IP network to the PSTN when the QoS degrades. When
QoS on the IP network returns to normal, call processing can be transitioned
back to the IP network.
The QoS thresholds (level and duration) defined on each RLC port determine
when the transitions occur. To determine appropriate thresholds for each site in
your network, consult your data network administrator. For more information,
refer to the Remote Gateway 9100 Series Network Engineering Guidelines (555-
8421-103).
Online/offline schedule
You can configure an online/offline schedule on the RLC to control when the
Remote Gateway 9150 unit can place and receive calls through the host PBX.
When the Remote Gateway 9150 unit is in offline mode, calls cannot be made or
received through the host PBX over the IP or PSTN.
Configure offline entries:
!
for times when the connection to the host PBX is not normally active, such
as during evenings and weekends
