functions such as voice packet generation and multiplexing). You can also use an individual DSP card for this
purpose.
Tenor CMS is managed by a unique Command Line Interface (CLI) management system. Through the CLI,
you can configure remote and local units. Just log on and configure items like chassis information, trunk
groups, signaling data, etc. In addition, you can assign specific numbers to be routed over the PSTN, rather
than IP. The CLI also provides a comprehensive on-line help system at your fingertips.
Quality of service is virtually guaranteed. SelectNet ™ Technology provides a “safety net,” which monitors
the IP network performance for VoIP calls. If the performance characteristics become unacceptable—accord-
ing to the specifications you assign— the call will be switched to the PSTN automatically. The unit’s simple
plug and play embedded system architecture brings VoIP technology to your network without changing your
existing telephony infrastructure. Your network stays as is and the call type is transparent to the user. This
technology boasts quality voice without compromising reliability.
Features
The Tenor CMS’s specific features are explained below.
Unique Design
Tenor CMS is a compact PCI chassis that supports the transmission of VoIP traffic via Ethernet connections. It
packs powerful VoIP features into one rack-mountable, slotted unit. In addition, the unit includes design fea-
tures such as load sharing power supplies and peripheral cards; the chassis is available in AC or DC power.
A high performance backplane supports two types of chassis-side busses: TDM and packet. TDM supports
2048 full duplex channels; it is used for transporting circuit switched traffic. The packet bus is used for carry-
ing packet-oriented data.
The slotted system architecture enables you to set the VoIP capabilities to suit your network’s needs; it is
available in three configurations: CMS (14 slot), CMS960 (8 slot), and CMS240 (2 slot) Through WAN inter-
face cards and DSP resources, you configure the number of VoIP channels your network requires.
State-of-the-Art Configuration and Network Management
A System Controller/CPU card controls all activity in the chassis; it passes all configuration information you
set via CLI to the other peripheral cards (T1, E1, DS1) and DSP resources. In addition, the DS1 card enables
you to employ T1, E1, and DSP functionality in the same card. Through the System Controller/CPU card, you
can connect a PC’s console port as well as an Ethernet hub, switch, or router. In addition, the System Control-
ler/CPU card provides one 10/100BaseT Ethernet port.
Once connected, the robust Command Line Interface (CLI) makes configuring a Tenor CMS easy. Through
the CLI, you are able to set all configuration parameters, such as chassis, signaling, and call type features. You
access the CLI through a simple telnet session. The state-of-the-art online help system, built into the CLI, pro-
vides help for all features and functionality. Just type help at any prompt, and data about that field will be dis-
played.
SelectNet™ Technology Safety Net
Tenor CMS’s built in SelectNet ™ Technology safety net feature virtually guarantees that each call going VoIP
will not only be routed successfully, but will deliver high voice quality.
