ces CBR Clock Mode

1.3.6.1.4.1.351.110.5.3.2.1.1.1.7

This specifies clocking mode of the CBR service. synchronous(1) : The transmit clock frequency is produced by an external source. srts (2) : Synchronous Residual TimeStamp(SRTS) is an asnychronous clocking method. The SRTS measures the difference between the service clock(received on the CBR interface) and the network-wide reference clock. The difference is the Residual Time Stamp(RTS). The RTS is propogated to the remote end of the circuit in the AAL1 header. The receiving end reconstructs the clock by adjusting the reference clock by RTS value. adaptive(3) : In adaptive clocking, the source CES IWF simply sends data to the destination CES IWF. The destination CES IWF writes data to the segmentation and re-assembly(SAR) buffer reads it with local T1 service clock. The local (interface) service clock is determined from the actual CBR data received. Only synchronous(1) mode is supported in CESM-4P and CESM-T3.
