Outputs are user configurable to be normally high or normally low. Default is normally
low (relay inactive). Additionally, a user can select on the Alarm I/O connector, a
normally closed or normally open contact pair.
For information on TTL input limits and relay output voltage and current maximums,
refer to Alarm I/O Port on page 2-6.

Description
Rack attachment bracket for the IDU. One ear has a grounding
stud for IDU grounding. The ears can be fitted either side and
provide flush-with-rack-front mounting.
2-pin D-series 2W2C power connector. Includes screw
fasteners.
5A time-lag fuse and power on/off switch. ON is when the fuse
head is in the vertical position; OFF is when the head is rotated
to the horizontal '0' position.
Type N female connector for jumper cable connection to the
surge suppressor located at the cable entry point to the
building.
RJ-45 connector provides a V.24 serial interface option for
Portal. It supports a default IP address, which means
knowledge of the Terminal IP address is not required at login.
The DB-9 connector provides one synchronous or
asynchronous data service channel. Selection of synchronous
(64 kbps) or asynchronous (max 19.2 kbps) is via Portal.
HD-15 connector provides access to two TTL alarm inputs and
four form C relay outputs. Connections are mapped in Portal.
ODU Status LED provides indications of:
Off IDU power off
Green Normal operation
Orange flashing Configuration not supported, software/
hardware incompatible, or diagnostic mode
selected, such as Tx Mute.
Red Critical alarm (traffic affecting)
