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.

asynchronous data service channel. Selection of synchronous
(64 kbps) or asynchronous (max 19.2 kbps) is via Portal.
7 Alarm I/O HD-15 connector provides access to two TTL alarm inputs and
four form C relay outputs. Connections are mapped in Portal.
8 ODU 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)
