Flag J1 Ignore; Frame-Format - HP 6600 Command Reference Manual

sdh: Sets framing format to SDH.
sonet: Sets framing format to SONET.
Usage guidelines
Inconsistency between the c2 and j1 settings of the sending POS interface and the receiving POS
interface causes alarms.
The J0 byte can be any character in the network of the same carrier. If two carriers are involved, make
sure the sending and receiving devices use the same J0 byte at their network borders.
Examples
# Set the SDH overhead byte J0 of POS 2/1/0 interface.
<Sysname> system-view
[Sysname] interface pos 2/1/0
[Sysname-Pos2/1/0] flag j0 sdh ff
