IP113M LF
Preliminary Data Sheet
2.3.4
Remote monitor
Refer to the diagram below, users can instruct central IP113M LF, on the right, to issue a status request
frame to get status defined in TS-1000 by programming MII register 24. The terminal IP113M LF, on the
left, receives the status request frame and sends out its current status as a response frame onto the fiber
port when it is available. The central IP113M LF receives the status frame and stores the status of
terminal IP113M LF to its MII register 23. An acknowledge maintenance frame is store to MII register
26~30. The status of terminal IP113M LF is shown on the LEDs of central IP113M LF.

Remote control read
Users can instruct central IP113M LF to issue a remote control read frame to read the MII register of
terminal IP113M LF by programming MII register 24. The bits [11:7] of the register 24 are filled with the
address of register and bits [6:4] of the register 24 are filled with “011”. The terminal IP113M LF receives
the frame and sends out the content of the MII register to central IP113M LF when it is available. The
central IP113M LF receives the frame and stores the data to MII register 27. An acknowledge
maintenance frame is stored to MII register 26~30. The status of terminal IP113M LF is shown on LED of
central IP113M LF.

Remote control write
Users can instruct central IP113M LF to issue a configure frame to write the MII register of terminal
IP113M LF by programming MII register 24 and 25. The bits [11:7] of the register 24 are filled with the
address of register and bits [6:4] of the register 24 are filled with “111”. MII register 25 defines the data.
The terminal IP113M LF receives the configure frame, configures itself according to the content of the
frame and sends out its current status as a response frame onto the fiber port when it is available. The
status of terminal IP113M LF is shown on LED of central IP113M LF.
