2. E1 (SDH Framing, STS3)

To configure an E1 on an SDH framed port with an STS3 path:

1. Configure an STS3 path on the port.

2. Configure one of the three TUGs for a VT2 payload.

3. Create a VT2 path with an E1 payload on the STS3 path / TUG.

4. Create an E1 on the VT2 path.

Use the info command to display configuration information.

Notes:

• the CLI identifier for the VT2 path command is vt2-tugNum.vtGroupNum.vtNum, where:

  • tugNum is the TUG number, which can be 1, 2, or 3

  • vtGroupNum is the VT group number. A TUG3 contains seven VT groups, so vtGroupNum can be from 1 to 7

  • vtNum is the VT2 number. A VT group can hold three VT2 paths, so vtNum can be from 1 to 3

• the CLI identifier for the TDM e1 command is similar to the path command, namely, tugNum.vtGroupNum.e1Num, where:

  • e1Num is equal to vtNum
