Co-existence of data and voice traffic, and emergence of sophisticated mobile networks, almost always requires some form of equipment synchronization. In today's de-regulated telecom environment, synchronization distribution is a complex issue, since traffic signals often traverse several synchronization domains.
Interfacing problems affecting the quality of synchronization are almost inevitable. Oscilloquartz presents to the users a family of solutions to solve synchronization interfacing problems. They are based on the synchronization of equipment via re-timed E1 or DS1 signals.
Re-timing consists in “imprinting” the timing of an available synchronization signal onto a given traffic signal, usually an E1 or a DS1 signal.
In the Re-timing function, the outgoing traffic signal contains the traffic data coming from the traffic input and the timing coming from the synchronization input. The outgoing traffic signal can then be used for synchronising other telecom equipment such as a switch or a base station.
Re-timing is useful in all situations, where there is no other way than taking a traffic-carrying E1/DS1 signal to synchronise an equipment, and when the original E1/DS1 signal is affected by excessive levels of wander.
Although synchronization is usually distributed via the SDH or SONET transport network, there are situations where this type of synchronization cannot be used. If a synchronous equipment such as a switch does not feature an external timing input, there is no other way than using one of the traffic-carrying E1/DS1 signals entering the switch its synchronization.
E1/T1 based retiming synchronization solutions by Oscilloquartz is the number one set of solutions and provide the highest capabilities for high performance reference when state of the art stability and competitive accuracy are needed at a minimum price. Oscilloquartz offers numerous variants, from single channel stand alone box up to 56 channels GPS based retiming.
The alarm threshold and monitoring parameters of the instrument are accessible for read and write operations through the local RS-232.
