How to Enable the ITU-T G.703 2048kHz Synchronization Interface (T12) on the DS26303 LIU

Abstract: Maintaining clock synchronization among multiple pieces of telecommunications equipment is an essential feature in any large installation. One common method of clock distribution is specified by the ITU-T G.703 2048kHz synchronization interface (T12). While the DS26303 E1/T1/J1 octal line interface unit (LIU) fully supports this specification, it needs some additional configuration settings for proper operation. This application note describes how to enable the 2048kHz synchronization interface mode and configure the DS26303 for use in clock-distribution applications.
