Startum 3 Timing Module
The second output on the MSTM-S3-TR can be synchronous at frequencies from 8 kHz up to the output frequencies. The MSTM-S3-TR acts as a complete timing module for general Stratum 3 timing applications, and is designed to replace similar units from TF Systems (TF118B) and Ralton (SY0001B). It is ideal for SONET, TDM, SDH and PDH applications, including switches and routers.
Features of the new MSTM-S3-TR include 2 synchronous outputs available from 8 kHz to 77.76 MHz, PLL-TVL early warning reference limit alarm, slows controlled entry into Hold Over and Free Run, 1 Hz loop SONET bandwidth, stable OCXO frequency source, dual hitless switchover, and freerun and holdover
