Vivinet Diagnostics is a product that can be purchased separately and used in conjunction with
Vivinet AppManager. When Vivinet AppManager receives a call quality alert from a Nortel voice
system such as a CS 1000 or BCM for a call in progress, AppManager generates an alert.

The alert from Vivinet AppManager activates Vivinet Diagnostics, which traces the path of the
call, collects diagnostic information and can perform root cause analysis and save results for
further analysis and action.
WMS 2300
The WMS is useful for monitoring the physical layer of the WLAN network for problems that
ultimately impact voice quality. The WMS is the trap receiver for all WLAN 2300 series products.
Data collected from periodic polling of the WSS 2300 can be shown in graph format.
Another critical feature of the WMS is the ability to locate and track users within the building.
Without this ability, troubleshooting a poor voice quality report from a user becomes much more
difficult. Knowing where the user is allows you to correlate the issue the user is reporting with the
latest site survey data for that area of the building. The basic mechanism for client location is to
identify the current AP and measure signal strength received in order to plot a graph around the
current AP.
3.1.4 Element management Communication Server 1000 Telephony Manager
Voice devices, from stations to communication servers, are configured from the Communication
Server 1000 Telephony Manager server, including CS 1000 and Meridian 1 products. Station
administration can also be done through Communication Server 1000 Telephony Manager. It
does have bulk configuration capabilities, but ultimately Communication Server 1000 Telephony
Manager best serves smaller to medium size environments. For larger VoIP installations,
Enterprise Subscriber Manager is a more scalable set management platform. Note that the actual
configuration of the WLAN Handset 2210/11/12 is done manually or through the DHCP server,
while the call server aspects of the handset (TN, DN, and so on) are configured on the CS 1000
or Meridian1, preferably through Communication Server 1000 Telephony Manager.
