Configuring Virtual Tributary Mapping

 

You can configure virtual tributary mapping standard as either International Telephony Union standard (itu-t) or KLM standard (klm). Here, the KLM standard is set by default. For more information about virtual tributary mapping, see Configuring Channelized STM1 Interfaces.

To configure virtual tributary mapping on Channelized STM1 IQ and IQE PICs:

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level, where the interface name is cau4-fpc/pic/port.
  2. Configure virtual tributary mapping option in KLM standard. By default, virtual tributary mapping uses KLM standard.
  3. Configure virtual tributary mapping option in ITU-T standard alternatively.

To configure virtual tributary mapping on STM1 PIC:

  1. In configuration mode, go to the [edit chassis fpc slot-number pic pic-number] hierarchy level.
  2. Configure virtual tributary mapping option in KLM mode. By default, virtual tributary mapping uses KLM mode.
  3. Configure virtual tributary mapping option in ITU-T mode alternatively.

Channelized STM1-to-E1 Channel Mapping lists the KLM mappings used by the Channelized STM1-to-E1 PIC interfaces.
