Capabilities
SelectNet™ Technology Safety Net (for Tenor AXM and Tenor AXE configurations)
Quality of service is virtually guaranteed. Tenor AX ’s built-in patented SelectNet ™ Technology
provides a “safety net,” which virtually guarantees that each call going VoIP will not only be routed
successfully, but will deliver high voice quality.
SelectNet monitors the IP network performance for VoIP calls. If the performance characteristics
become unacceptable—according to the delay, jitter, and packet loss specifications you configure—
the Tenor AX will switch the call to the PSTN automatically and transparently. The Tenor continu-
ously monitors your data network for jitter, latency and packet loss, and transparently switches cus-
tomer calls to the PSTN when required.
PacketSaver™ reduces bandwidth consumption
PacketSaver packet multiplexing technology reduces the amount of IP bandwidth required to sup-
port multiple calls flowing between two endpoints. PacketSaver minimizes bandwidth usage by
aggregating samples from multiple VoIP conversations and packing them into a larger IP packet
with a single IP header. The process removes the need to send a bulky IP header with individual
voice packets. As a result, it eliminates the transmission of redundant information.

Virtual Tie Trunk
The Tenor unit can emulate any tie trunk. It provides all of the functionality of a tie trunk, including
the considerable cost savings, but eliminates the need for a PBX trunk to be configured, or marked
as a tie trunk. (A traditional tie trunk is a PBX-configured direct connection between two PBXs in
separate locations. The tie trunk bypasses the PSTN network, which results in considerable savings.)
Your PBX does not need any additional configuration. The Tenor AX treats all trunks the same with-
out compromising voice quality.
