Device Interconnection Control
Description
This feature provides a means of disallowing connection between devices
of different types. The feature is primarily intended to control trunk inter-
connection but applies to other devices as well. This is intended to
provide a method of meeting interconnection regulations imposed by vari-
ous regulatory authorities.
The checks apply when a device calls another device, when a transfer
(supervised or unsupervised) is attempted and when the console attempts
to perform operations on devices. The sections in this practice mention
Device Interconnection checks where they apply.
See F/ash Con&o/for details on controlling the ability of extensions to flash
when extensions are involved with trunk calls.
There are three aspects of the feature: Tenant Interconnection, the Device
Interconnection Table, and COS Options.
Tenant Interconnection, CDE Form 05 (Tenanting Interconnection Table) is
described in Practice 9109-096-230_NA,Tenanting. The check for tenant
connection is done when the Device Interconnection Table check is done.
