9.3Telco Alarm Connector
Many telecom facilities have existing alarm infrastructure. When an error condition occurs, the alarm system activates an audible alarm, flashes lights to help technicians locate the source of the alarm, and possibly interacts with a computer system that is monitoring the facility. Error conditions are typically classified as minor, major, or critical errors, and an LED identifies the current alarm state.
The telco alarm system consists of a distinct dry contact relay that corresponds to each alarm state. These are open or closed depending on the state and are entirely under software control (except power). The default is the no alarm state. The normally open [NO], normally closed [NC], and common [COM] relay contacts are provided to the DB- 15 connector in line with existing industry practice. There are also reset inputs to clear the minor and major alarm state.
Note: There is no reset for the critical state.
There is an additional set of contacts (common [COM] plus normally open [NO]) that is used to indicate a power system failure. There is no normally closed [NC] contact for this relay nor is there a reset for clearing it.
The telco alarm contacts on the MPCMM0002 CMM comply with the alarm connector requirements outlined in Section 2.7.7 of the PICMG* 3.0 specification.
Caution: The RTM connections for the telco alarm connections are wired parallel to the connections on the CMM faceplate. Do not connect cables to both the
