Configuring the Overhead Byte
Context
Different device manufactures require different overhead bytes for a POS interface. Ensure that the C2, J0, and J1 overhead bytes of both ends are the same. Otherwise, the two devices cannot be connected.
Procedure
- Run system-view
The system view is displayed.
- Run interface pos interface-number
The POS interface view is displayed.
- Run
- flag c2 c2–value
- flag j0 { 1byte-mode value | 16byte-mode value | 64byte-mode value }
- flag j1 { 1byte-mode value | 16byte-mode value | 64byte-mode value }
The overhead byte is configured for the POS interface.
The default overhead bytes for the SDH are used: The C2 overhead byte is 0x16, J0 and J1 overhead bytes are blank.
