MOT(config-if)#pos flag j1 <hexnum>
where:
hexnum is the hexadecimal value for the j1 byte.
9. The s1 byte identifies the timing source for SONET frame synchronization. To set
the hexadecimal value for the s1 byte, use the pos flag s1 command in Interface
Configuration mode, as shown below:
MOT(config-if)#pos flag s1 <hexnum>
where:
hexnum is the hexadecimal value for the s1 byte
