3 Connecting External Alarm Cables
You may connect the external alarm cables in all interface areas of the equipment at the same
time. For details, see the
Connecting Clock Cables and Cables in the Interface Area
procedure in
Installing and Routing Clock Cables
in this document.
NOTE
Connection to the Eight Housekeeping Alarms (T32 and T16 Subracks Cascaded)
NOTE
To connect a single subrack to the
external centralized alarm system, directly
connect the ALMO1 interface of the
subrack to the alarm system.
1. The cables are connected in a similar
way in multi-subrack configurations. The
only difference lies in the number of
cascaded interfaces.
2. The cables are connected in a similar
way in multi-subrack configurations. The
only difference is the board where the
external alarm interfaces are located.
