1.2 STS1 with VT1.5 payload

To configure a DS1 on an STS1 with a VT1.5 payload:

1. Create the STS1 path and set the payload to VT1.5.

2. Create the VT1.5 path on the STS1 path.

3. Create the DS1 on the VT1.5 path.

Use the info command to display configuration information. The example below creates two VT1.5 paths, each with its own DS1.

         sonet-sdh
             path sts1-1
                 payload vt15
                 no shutdown
             exit
             path vt15-1.1.1
                 payload ds1
                 no shutdown
             exit
             path vt15-1.7.4
                 payload ds1
                 no shutdown
             exit
         exit
         tdm
             ds1 1.1.1
                 no shutdown
             exit
             ds1 1.7.4
                 no shutdown
             exit
         exit
         no shutdown

Notes:

• the CLI identifier for the VT1.5 path command is vt15-stsNum.vtGroupNum.vtNum, where:

  • vt15- is a keyword

  • stsNum is the STS1 number, which can be 1, 2, or 3

  • vtGroupNum is the VT group number. An STS1 frame contains seven VT groups, so vtGroupNum can be from 1 to 7

  • vtNum is the VT1.5 number. A VT group can hold four VT1.5 paths, so vtNum can be from 1 to 4

• the CLI identifier for the TDM ds1 command is similar to the path command, namely, stsNum.vtGroupNum.ds1Num, where:

  • ds1Num is equal to vtNum
