DS3100 Description
When paired with an external TCXO or OCXO, the DS3100 is a plete central timing and synchronization solution for SONET/SDH network elements. With two multiprotocol BITS/SSU receivers and 14 input clocks, the device directly accepts both external timing and line timing from a large number of line cards. All input clocks are continuously monitored for frequency accuracy and activity.
