Change is a process by change, and capable of emitting pre-warning signal is answered when clock is deteriorated to a certain degree, reminds maintenance personnel that concern should
Equipment.Real-time Alarm then when clockwork performance is exceeded, issues alarm signal, reminds maintenance personnel's on-call maintenance.
(4) test philosophy and test request
Monitoring principle tests the net synchronization capability of communication equipment with clock monitoring net, and mainly test business device tracking is fixed
When signal drift generate index: time interval error (TIE), the root of clock monitor net capturing service equipment timing output signal
Maximum time interval error (MTIE), time deviation (TDEV) are calculated according to TIE, MTIE, the TDEV generated with predefined drift
Template is compared, if meeting template requirement, illustrates that business device detector timing properties b is met the requirements, and otherwise generates fault warning note
Record.
Test request, the present processes further include testing the net synchronization capability of business device in communication network, pass through test
The net synchronization capability of communication network obtains accurate test data, and the synchronism of communication network is judged according to these test datas
Energy.Purpose to the net synchronization capability test of communication network is the net synchronization capability in order to examine digital synchronous network, the parameter being related to
Having time interval (TIE), maximum time interval (MTIE), time deviation (TDEV), frequency deviation FREQ and shake peak-to-peak value (UI
Pp) etc..Test point to the test of communication network net synchronization capability is digital synchronous network interface, is network interface, including it is at different levels when
The input/output end port of the input/output end port of clock equipment and equipment relevant to synchronization link (such as transmission device).For
The signal of BITS equipment is directly passed in and out, interface is defined on the dedicated DDF frame of digital synchronous network；For indirect disengaging BITS equipment
Signal, interface is defined on the DDF frame of relevant device or at the input/output interface of equipment.The test of communication network net synchronization capability
A most important principle is that the operation of communication network and its synchronizing network must not be influenced during the entire process of test.
In the above-described embodiments, by develop it is a kind of can fusion frequency be synchronous and the multifunction timepiece of clock monitor is flat
