2.1 STS1 with channelized DS3 payload

To configure an E1 on an STS1 with a DS3 payload:

1. Create the STS1 path with SDH framing and set the payload to DS3.

2. Create a TDM DS3 with a channelized E1.

3. Create the corresponding E1.

Use the info command to display configuration information. In the example below, DS3 1 carries two E1 channels.

         sonet-sdh
             framing sdh
             path sts1-1
                 payload ds3
                 no shutdown
             exit
         exit
         tdm
             ds3 1
                 no shutdown
                 channelized e1
             exit
             e1 1.1
                 no shutdown
             exit
             e1 1.21
                 no shutdown
             exit
         exit
         no shutdown

Notes:

• the CLI identifier for the path command is sts1-stsNum, where:

  • stsNum is between 1 and 3

• the CLI identifier for the TDM ds3 command is ds3Num, where:

  • ds3Num is equal to stsNum

  In the example above, DS3 is configured on sts1-1, hence the command ds3 1. If sts1-2 or sts1-3 was configured instead of sts1-1, the corresponding ds3 configuration would be ds3 2 or ds3 3, respectively.

• the CLI identifier for the TDM e1 command is ds3Num.e1Num, where:

  • e1Num is between 1 and 21 because a DS3 can carry 21 E1s
