DIP switches
Three cards have DIP switches that must be configured prior to card insertion.
On the LMX, DIP switch settings identify the LMX’s position with respect to
the LMI and RMI. DIP switch settings on the LMI and RMI determine binary
daisy chain address, T1 line build-out, framing mode, terminal baud, and
terminal settings.
Man-machine interface
See “Installation and configuration” on page 47 for a detailed explanation of
MMI commands, and “Man-Machine Interface (MMI) commands” on
page 119 for a listing and brief discussion of each command.
Daisy chaining
LMIs may be daisy-chained together to share a single maintenance terminal
and a single SDI port. Each LMI has a DIP switch-configurable daisy-chain
address. LMX and RMI status can be determined by logging into their
associated LMI.
SDI functionality
The LMI may be connected to an SDI port on the switch, providing a “host
pass-through” capability at both local and remote sites. This allows
craftspeople at the remote site access to the system TTY connection, and
provides a single MMI/SDI terminal at the local site.
Alarms
An alarm condition is indicated by the appropriate LMI and RMI faceplate
LEDs. The cards are also equipped with a single dry alarm contact output to
indicate alarm status. A normally-closed and a normally-open dry alarm
contact point are both provided. These contacts may be connected to
customer-provided alarm-sensing equipment, if desired.
