MMI mode
In the MMI mode, a terminal, or TTY, is connected to the local MMI port (P5
on the LMI Multi I/O cable) at the LMI or at the remote MMI port (P5 on the
RMI Multi I/O cable) at the RMI. The MMI interface characteristics are based
on the following switch settings:
• Speed is configured using SW3 position 5:
— OFF = 9600 bps or
— ON = 2400 bps.
• Parity, character width, and stop bit are configured using SW3,
position 6.
— OFF = parity-None, character width-8, stop bit-1 (N, 8, 1) or
— ON = parity-Mark, character width-7, stop bit-1 (M, 7, 1).
Host MMI Interface
An RS232 Man-Machine-Interface (MMI) communication port is provided
for maintenance, configuration, and diagnostics. To begin working at the
MMI, type L. MCR then prompts the user for a password that if entered
correctly, will allow the user to interface with the MCR.
Table 18 on page 75, lists the MMI commands available at the Mini-Carrier
Remote MMI interface with a brief description of each:
