The devices represented in <strong>Optivity</strong> NMS are OTM Servers that manage individual<br />

voice elements. The OTM Servers are manually added to the <strong>Optivity</strong> NMS network by<br />

the administrator.<br />

The OTM Alarm Notification application reformats, filters, and forwards traps to<br />

<strong>Optivity</strong> NMS. Because OTM forms the main representative agent for Meridian 1<br />

systems, Communication Server 1000 systems, and related voice devices, all alarms<br />

received by <strong>Optivity</strong> NMS result in the change of status state of OTM depicted in the<br />

<strong>Optivity</strong> NMS InfoCenter. The traps are reformatted into the open alarm II format.<br />

Typically, only critical alarms are forwarded to <strong>Optivity</strong> NMS.<br />

When <strong>Optivity</strong> and OTM coreside on the same server, the OTM trap system disables its<br />

Trap Server and instead sends traps to the <strong>Optivity</strong> Trap Server.<br />

Figure 278 shows alarms being forwarded from OTM Servers to <strong>Optivity</strong> NMS.<br />
