68 Installation and configuration
Host SDI mode
In the Host SDI mode, a terminal is connected to the MMI port (P5 on
the RMI Multi I/O cable) at the RMI. This terminal becomes the system
maintenance and service change TTY. At the local site, the LMI connects
to the MMI port (P5 on the LMI Multi I/O cable) and to an SDI port (P6 on
the LMI Multi I/O cable) of an SDI card.
For the MMI port at the RMI to be able to communicate over the SDI port
connected to the LMI, the interface characteristics must be the same:
•
Speed is set at the factory to 9600 bps, but is DIP switch configurable
to 2400 bps using SW3, position 5.
•
Parity, character width, and stop bit are configured using SW3, position
6:

In this mode, the remote TTY or terminal becomes a system TTY that can
access overlays and perform system configuration, maintenance, and
diagnostics, which are the same functions performed by the local system
TTY. Refer to
available MMI commands and the definition of each.
To log in to the host for SDI operation, you should first log in using the
MMI terminal in the MMI mode, then you should log into the terminal as
host:

The Host SDI mode is accessed from the MMI mode by entering the HOST
(HO) command at the terminal or TTY. In this mode you can configure
and maintain the entire system. For example, LD 45 can be activated to
perform loopback testing.
To exit this mode, enter @@@.
OFF = parity-None, character width-8, stop bit-1 (N, 8, 1)
ON = parity-Mark, character width-7, stop bit-1 (M, 7, 1)
