NFORMATION
This feature allows a portion of the possible connections to always be available to specific devices
for both inbound and outbound calls. To increase flexibility, this feature may be configured to
either allow or prevent bandwidth overlap. Bandwidth overlap will allow normal devices to use a
certain number of lines, while a special class of super devices would be allowed access to both the
normal bandwidth (designated in the default profile) as well as special super device bandwidth
(designated in the configured device profile). "No overlap" would restrict each set of devices to
their own lines.

When configuring your bandwidth reservation, consider the following:
•
•
This is a BRI-only feature since bandwidth is reserved per-line.
•
It is necessary to reject calls from devices who have mistakenly called in on a line reserved for
other device(s).
other device(s).
•
Outbound calls are also restricted to the lines reserved for a device.
•
When Bandwidth Reservation is disabled, any device will can connect on any line.
•
When Bandwidth Reservation is enabled, a default profile list of lines will be configured for use
by all devices that are not configured to use an alternate profile in the reserved list. This default
profile list may be configured to remove lines from general use.

ONNECTIONS
A semipermanent connection is a connection that is up at all times. With semipermanent
connections, one or more switched calls are made at system start-up, and are kept up until system
shutdown. This feature minimizes the number of calls which the system makes, and maximizes the
number of active call minutes.

Every device can have one semipermanent connection. Each semipermanent connection is com-
posed of one or more calls. The number of semipermanent devices is limited to the maximum num-
ber of calls allowed by the system.
