RLC Installation and Administration Guide 27
June 2005 RLC description
DN priority
The RLC provides multiple priority levels for Remote Gateway 9150 unit users:
„
PSTN only
„
high
„
normal
„
IP only
If you configure this feature, you must also configure an amount of bandwidth to
save for the High priority DNs. You must also identify the privileged DNs
through Configuration Manager. This information does not apply to Remote
Gateway 911x series or Digital Telephone IP Adapters.
The RLC uses the priority reserved bandwidth for high priority DNs. When only
bandwidth for high priority DNs remains on the network, users dialing out on
normal priority DNs hear a fast busy signal. For details on configuring DN
priority, refer to “RLC port configuration” on page 186.
Online/Offline table
You can configure the RLC to establish or terminate host connections at
specified times of the day. This feature limits excessive connection charges for
idle host connections. For details on configuring the Online/Offline table, refer
to “Online/Offline table configuration” on page 219.
Bandwidth allocation
Configuration Manager provides options for you to allocate PSTN bandwidth
for Remote Gateway 9150 stations. This does not apply to Remote Gateway
911x series or Digital Telephone IP Adapters.
„
Priority reserved bandwidth
You can reserve bandwidth for certain DNs that need prioritized access to
Remote Gateway 9100 Series channels. You can configure high priority DNs on
the RLC Port Configuration property sheet. These DNs consume Priority
Reserved Bandwidth before using unreserved bandwidth.
„
Extra bandwidth
Configuration Manager allows you to reserve a certain amount of bandwidth for
accessing a remote unit. When the amount of bandwidth available falls below
the level that you configure, the RLC opens additional B-channels to the remote
unit.
