Managing Trunk Connections - Nortel Remote Office 9150 Installation And Administration Manual

Planning for installation

Managing trunk connections

You can manage trunk connections to the host PBX in several ways:
n
Put the Remote Office 9150 unit into offline mode, so that it cannot receive
or make calls through the host PBX when operating in circuit-switched
mode.
n
Define call duration and idle timers, if the trunk connection is defined as
on-demand.
n
Define minimum and maximum bandwidth allocation settings.
n
Use the QoS transitioning technology.
Quality of Service 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 Quality of Service
degrades. When Quality of Service on the IP network returns to normal, call
processing can be transitioned back to the IP network.
The points at which the transition occurs are determined by the Quality of
Service thresholds (level and duration) defined on each RLC port. To determine
appropriate thresholds for each site in your network, you should consult your
data network administrator. For more information, see the Remote Office
Network Engineering Guidelines (555-8421-103).
