Page GL-7
When digital signals are transmitted over a communications link, the receiving end must be synchronized with the transmitting end to receive the digital signals without errors using clock synchronization. A system synchronizes itself by extracting a timing signal from an incoming digital stream. All the digital facilities in a network operate from a single common clock, preferably a port connected to a digital PSTN facility on a hub system or a system that connects two network systems. In this case, all digital facilities specify a loop clock source. One system in a network may be specified as a local clock source when no functioning digital facility in the network is connected to the PSTN. All other digital facilities then use this clock and specify their clock sources as loop. Primary, secondary, and tertiary clock sources are specified to allow backup synchronization in the event that the primary source is out of service.

U
UDP unambiguous numbering
Uniform Dial Plan uninterruptible power supply unit load unmonitored extension
(Uniform Dial Plan) Composed of the local dial plan and non-local dial plan . A dial plan that allows a caller at any extension in a private network to dial the same number of digits to reach any other extension in the private network, even if the originating extension is physically connected to one communications system and the terminating extension is physically connected to a different communications system.
The practice of numbering of extension ranges, remote access codes, or other system components to avoid routing conflicts in 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 , a system routes the call to
Extension 441 immediately, without considering the last dialed digit.
