cbr DS1E1 Port Configuration Timing

1.3.6.1.4.1.43.1.12.3.1.1.15.2.1.1.5

This object indicates the type of input clock service configured for the specified T1/E1 port interface. Synchronous Residual Time Stamp (SRTS) and Adaptive timing modes are ONLY available in unstructured mode. System configures the port interface to use the system reference clock within the shelf as a reference for transmitting. Loop uses the input port Rx clock as the timing source. An error is returned if an access is attempted to set this object in an inappropriate port mode (eg. SRTS is applied in structured voice mode). The default value is adaptive (4).
