6.2 Alarm Interface, FAN-ALARM
The ONS 15305 Alarm Interface is described in the following sub-sections.
6.2.1 Description
ONS15305 provides facilities to report a minimum of 4 auxiliary alarm inputs for associated equipment, e.g. power unit failure battery condition, cabinet door etc. and 2 dedicated alarm outputs. The alarm outputs are related to the unit alarm indicator and the traffic alarm indicator. The input alarms are reported to the management system and are activated by a closed or open loop condition between a pair of contacts. See Figure 6-1.
Figure 6-1 Alarm Input and Output Overview
6.2.2 Connectors
The alarm interface connector is a 9 pin DSUB type connector, with the pin-out given in Table 6-1.
6.2.3 Electrical Parameters Alarm Input
Electrical Specification at Alarm Input is found in Table 6-2.
6.2.4 Electrical Parameters Alarm Output
Electrical Specification at Alarm Output is found in Table 6-3.
6.3 Auxiliary Interface
The ONS 15305 Auxiliary Interface is described in the following sub-sections.
6.3.1 Description
ONS 15305 offers a proprietary Auxiliary interface for termination of overhead bytes selected from the different STM-N interfaces. The Auxiliary interface is located on the System controller module, SYSCONT-SD128-RJ45.
Each STM-N interface can be configured to terminate one of the following overhead bytes: E1, F1 or E2. The byte to be terminated is selected from the network management system together with a unique time slot number n, where n equals 1-15 or 17-31. The Auxiliary interface is a framed E1 interface, according to ITU-T G.704, where time slot 1-15 and 17-31 can carry one overhead byte each, according to the configuration described above.
The interface is synchronous which means that the incoming STM-N need to be synchronized with the T0 reference clock in the ONS 15305 and the incoming framed E1 need to be synchronized with the outgoing framed E1. Bit slips will occur if one of the interfaces is free running.
6.3.2 Connector
The connector is a RJ-45 connector, with the pin-out described in Table 6-4.
