Meridian 1
OTM 2.2 is used as the configuration, administration, and maintenance
interface for IP Line 4.5 on a Meridian 1. Element Manager cannot be used,
as Element Manager is located on a Signaling Server, and there is no
Signaling Server in a Meridian 1.
Corporate Directory
OTM 2.2 is necessary for creation of the Corporate Directory database.
SNMP and alarms
Element Manager does not provide a SNMP alarm browser, so the OTM 2.2
Alarm Manager is recommended when SNMP alarm collection is required.

System configurations

Although IP Line 4.5 can be used in different system configurations and its
use can vary in those configurations, there are four basic system
configurations. See Table 2.
IP Line 4.5 can use the Signaling Server if the Signaling Server is deployed
in the system configuration.
