The evaluation board can be operated in either Hard- ware mode or Host mode. In Hardware mode, switches and bed stake headers are used to control the line con- figuration and channel operations for all eight channels. In Host mode (Serial or Parallel), the evaluation soft- ware, switches, and bed stake headers are used to control the line configuration and operating mode set- tings for each channel. In both Hardware and Host modes, the board may be configured for E1 75 Ω or E1 120 Ω operating modes. In both modes binding post connectors provide easy con- nections between the line interface connections of the CS61880 and any E1 analyzing equipment, which may be used to evaluate the CS61880 device. Bed stake headers allow easy access to each channel’s clock and data I/O digital interface. Eight LED indictors display the Loss of Signal (LOS) conditions for each channel during Hardware and Host modes. An LED indictor is used on the Interrupt pin to in- dicate a change of state.
