Configuring Transmission SA Bits of the S1 Byte

Configuring Transmission SA Bits of the S1 Byte

Context

A multiframe transmitted between different types of BITS interfaces consists of eight sub-multiframes. Each sub-multiframe contains five unused bits, namely, SA4 bit to SA8 bit. You can use any one of these unused SA bits to transmit the SDH synchronization code (S1 byte). Each of the eight sub-multiframes carries one of the eight bits of the S1 byte. If the sender and the receiver are of the same model, it is not necessary to perform this configuration because the device can identify the S1 byte regardless of which bit transmits it. For different models of switches that are interconnected through BITS interfaces, specify the same bit that transmits the S1 byte on both ends to ensure that both ends can identify the S1 byte.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run clock recv-sa-bit { sa4 | sa5 | sa6 | sa7 | sa8 } { bits0 | bits1 }

    The bit of the SA bits from which the SDH synchronization status code (S1 byte) is received is specified.

    By default, the S1 byte is transmitted in the SA4 bit.

  3. Run clock send-sa-bit { sa4 | sa5 | sa6 | sa7 | sa8 } { bits0 | bits1 }

    The bit of the SA packet that is used to transmit the SDH synchronization status code (S1 byte) is specified.

    By default, the S1 byte is transmitted in the SA4 bit.
