The practice of numbering of extension ranges, remote
access codes, or other system components to avoid
routing conflicts in private network or local calling. For
example, Extension 441 is unique when compared to
Extension 4410. However it is ambiguous, because a
system routes as soon as it matches the digits sent for a
call with the digits in a local plan or in a non-local dial plan
extension range. When a caller dials
routes the call to Extension 441 immediately, without
considering the last dialed digit.
See UDP .
See UPS .
Measure of the power load drain of a module, telephone,
or adjunct .
An extension for which no CTI application is receiving call
information. See also CTI link and monitored extension .
Unrestricted data channels (also called clear data
channels) allow the transmission of occurrences of more
than seven contiguous zero bits. If an unrestricted data
channel is requested and only restricted channels are
available, the call will be rejected. See also restricted data
channel.
(uninterruptible power supply) Device that connects to the
system to provide 117 VAC to the equipment when the
commercial power source fails.
(alternating-current voltage)
(direct-current voltage)
(voice messaging interface) An enhanced tip/ring port.
