Relay board RPJ

Removable RPJ board allows cCS to provide reservation of streams E1 during operation in high accessibility setting (one central board in standby, another – operating). In case of failure of main board, the system continues to operate using quick switching of E1 streams to the reserve one. Interfaces:

  • 8 / 16 E1 connections to active board
  • 8 / 16 E1 connections to reserve board
  • 8 / 16 E1 connections to MDF
