for indicating the multiplexing structure of a VC frame and the property of payload. The J1 and C2 bytes
are mainly used for interoperability between devices from different countries, areas, and vendors.
Examples
# Set the J1 byte to abcd for VC-4 frames on channel 1 of VC-4 on interface CPOS 2/0/0 in SDH mode.
<Sysname> system-view
[Sysname] controller cpos 2/0/0
[Sysname-Cpos2/0/0] flag vc-4 1 j1 sdh abcd

ft3
Use ft3 to configure the specified T3 channel to operate in FT3 mode and configure its FT3 DSU mode
or FT3 subrate.
Use undo ft3 to restore the default.
