Web• To maintain clock quality, it is important to specify limit to the number of cascaded clocks and set limit on degradation of the synchronization signal • Reference chain consists of K SSUs each linked with N SECs • Provisionally K and N have been set to be K=10 and N=20 - total number of SECs has been limited to 60 PRC SSU SSU
WebClock performance is specified in ANSI T1.101 with five categories from Stratum 1 through 4 (Table 1). The highest performance is Stratum 1. It is also known as Primary Reference Source (PRS) or Primary Reference Clock (PRC), although there is a difference between them. Unlike a stratum 1 clock a PRS does not need to be autonomous. WebVCL-2145, GPS Primary Reference (PRC) G.811 Clock with NTP Server May be used in multi-service applications as a G.811, Primary Reference (PRC) Clock and NTP Server 1/5/10MHz, 2.048MHz, 2.048Mbits with SSM, 1.544Mbits GNSS referenced outputs.
Modern telecommunications networks use highly accurate primary master clocks that must meet the international standards requirement for long term frequency accuracy better than 1 part in 10 . To get this performance, atomic clocks or GPS disciplined oscillators are normally used. Synchronization supply units (SSU) are used to ensure reliable synchronisation distribution. They have a number of key functions:
