Connection bandwidth
On the connection between the RLC and the Remote Gateway 9150 unit, you
can configure the following:
!
when to open additional B-channels (referred to as extra bandwidth)
!
how much bandwidth to reserve for high priority stations (referred to as
priority reserved bandwidth)
For instructions, refer to “Configuring ports” in the Reach Line Card
Installation and Administration Guide (NTP 555-8421-210).
Extra bandwidth
When available bandwidth is no longer sufficient to process active calls,
additional B-channels are opened according to the extra bandwidth setting. For
example, if you configure the extra bandwidth setting as 16 Kbps, another
B-channel opens when existing bandwidth is reduced to 16 Kbps or less.
Priority reserved bandwidth
The priority reserved bandwidth setting defines how much bandwidth to reserve
for high priority stations. The reserved bandwidth cannot be used by stations
configured as normal, IP only, or circuit-only priority. High priority stations
consume priority reserved bandwidth before consuming unreserved bandwidth.
For example, if you configure the priority reserved setting as 16 Kbps, then only
high priority stations can use this reserved bandwidth. When the reserved
bandwidth is being used for active high priority calls, additional calls from high
priority stations are processed using unreserved bandwidth. If no bandwidth is
available, calls to or from high priority stations are blocked until bandwidth
becomes available.
Local calling
The Remote Gateway 9150 unit allows you to place calls to other extensions
within your office or to telephones in your local community. This is
accomplished through the use of up to two local call appearance keys. Refer to
Chapter 6, “Using Remote Gateway 9150 stations,” for a detailed description of
the local call appearance keys.
