Cable Description and Installation
1.8.5 Alarm Cable Installation
The alarm cables attach to the rear of the ONS 15310-MA SDH at the ALARM In and ALARM Out
ports. The other ends of the cables plug into the alarm-collection equipment. Terminate the ends of these
cables according to local site practice. The pins on the ALARM In and ALARM Out ports correspond
to the 32 external alarm inputs and the 8 external alarm outputs (controls) that you can define using
Cisco Transport Controller (CTC).
Table 1-5 shows the default input alarm pinouts and the corresponding alarm numbers assigned to each
port. Refer to this table when connecting alarm cables to the ONS 15310-MA SDH.
