To configure a DS1 on an STS1 with a VT1.5 payload:
Create the STS1 path and set the payload to VT1.5.
Create the VT1.5 path and set the payload to DS1.
Create the corresponding TDM DS1.
There is one DS1 per VT1.5 path.
Use the info command to display configuration information. This example creates two VT1.5 payloads, each having a corresponding DS1 channel.

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