Meridian 1 products (as well as virtually all other Nortel products). It can discover the call server
equipment that it supports, it can display the information for the slot or port that the call server
components are attached to, and it can discover the TLAN and ELAN on a CS 1000 Signaling
server. It differs from Communication Server 1000 Telephony Manager in that ENMS is a
comprehensive monitoring platform for virtually all Nortel products, while Communication Server
1000 Telephony Manager supports only VoIP products and features. ENMS is the product that
ties all the other management packages together. Communication Server 1000 Telephony
Manager has more capabilities in terms of element configuration and data analysis (for voice
products) than ENMS.
Enterprise Network Management System 10.4 makes convergence management a quick and
easy reality with the Converged View in the new IP Service Management (IPSM) display. The
IPSM display provides a business-oriented overview of the Convergence Service. With IPSM, an
operator can see the status of overall service level that is being provided at a glance, and easily
zoom in with detailed troubleshooting tools if a problem is indicated. If a phone is unreachable, or
if there is a degradation of quality in a call, it is indicated in the IPSM tabular view. The call quality
alert shows the near-end and far-end IP address and Terminal Number (TN).
Figure 19 shows the IPSM overview with a list of the phones that are registered to a particular CS
1000 system. Many details, including type of phone (hard phone/soft phone, such as the IP
Softphone 2050, which has applicability to VoWLAN), firmware revision, IP address, set TN,
registered TN, source and destination IP port, and so on, are displayed. Phones or components
of the CS 1000 system change color to indicate status. The pie chart in the lower left corner of the
display is updated to show overall status and quality of the phones and CS 1000 systems in the
display.

When you click on a specific IP Softphone 2050 of interest, the panel in the lower right portion of
the screen displays details automatically, such as the CS 1000 system that the IP Softphone
2050 is registered with. You can then right-click on the phone to show a data network path trace
graphically. For troubleshooting purposes, you can view a path trace to the signaling server or
any other IP address.
