Appendix A: Getting Acquainted with Tenor CMS in the VoIP Network
Typical CMS Applications
Enterprise Network
The enterprise application is used whenever a Tenor CMS is going to be installed on to an existing voice line
to provide IP calls between company locations. Additional features such as “hop-off” or leaky area calling
may be used as well.
A typical enterprise network has two connection types: a line from the local PSTN to provide voice services to
a PBX, and an IP connection between their offices for data services. The Tenor CMS provides both of these
connections from a single chassis.
Several benefits to an Enterprise application include the following:
• Eliminates risk of sub-standard voice. The Autoswitch feature will send a call to the PSTN automatically
if the CMS detects that the network may threaten the quality of the VoIP transmission.
• Eliminates the possibility of vendor “lock-in”. The Tenor CMS can be used with virtually any PBX and
any routing architecture.
• Eliminates time and risk from a VoIP learning curve. A bypass feature enables your network staff to turn
VoIP on or off at a moment’s notice, which significantly raises the comfort level that both Technical and
Business Managers have any initial foray into VoIP implementation.
