VMUX-(FUN. DESCRIPTION)NETWORK SYNCHRONIZATION

NETWORK SYNCHRONIZATION

VMX-0100 supports a variety of clock input options for network synchronization. These can be:

·         Extracted PCM1 Clock

·         Extracted PCM2 Clock

·         Extracted Synchronous Data Channel Clock

·         External 2.048 MHz Clock

·         Internal Oscillator Clock

The user can specify synchronizing clocks in order of priority. In case of failure of a higher priority clock, the next available lower priority clock is automatically brought into the circuit. In parallel, alarms are generated in case of failure of highest and next to highest priority synchronizing clock.

VMX-0100 also gives out a 120Ω / 75 Ω G.703 2.048 MHz network clock for synchronizing the next equipment in the chain.
