Chapter 1: Overview

What is Tenor CMS?

The Tenor Carrier MultiPath Switch (CMS) is a high-density VoIP (Voice over Internet Protocol) H.323 switch that digitizes voice and fax data and transmits it over th e IP network. Tenor CMS is available in three configurations: CMS (14 slot), CMS960 (8 slot), and CMS240 (2 slot); each is a slotted, scalable system that intelligently switches calls over both the IP network and the PSTN in order to ensure high quality voice. Tenor CMS functions as a gateway, gatekeeper, and a border element. The gateway converts circuit switched calls to VoIP calls, the gatekeeper performs IP call routing functions, and the border element distributes the call routing directories throughout the network.

Each Tenor CMS is available with either AC or DC input power.

NOTE: Figure 1-1 illustrates Tenor units with AC power.

CMS240 (2 Slot)

The slotted system architecture boasts peripheral cards, which interface to various Wide Area Networks (WANs). Tenor CMS connects to T1/E1 lines operating in either a trunk circuit or line circuit configuration. The individual spans within the Tenor CMS may connect to either the PSTN or to T1/E1 termination equipment on the user premises (i.e., PBX).

The high performance System Controller/CPU card provides up to four 10/100BaseT connections and one RS-232 serial port connection; this card is an intelligent call routing engine which regulates system resources and configuration while coordinating all voice traffic activity in the unit. The DS1, T1, and E1 cards provide connections. The DS1 card also provides DSP processing (DSP is a signal processing resource; it performs

1-2 P/N 480-0005-00-15

Chapter 1: Overview

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 Comman d Li ne 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 the IP network performance for VoIP calls. If the performance characteristics become unacceptable—according 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

T enor CMS is a compact PCI chassis that supports the transmission of Vo IP traffic via Ethernet connections. It packs powerful VoIP features into one rack-mountable, slotted unit. In addition, the unit includes design features 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 carrying 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 interface 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 Controller/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, provides help for all features and functionality. Just type help at any prompt, and data about that field will be displayed.

SelectNet™ Technology Safety Net

T enor 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.

P/N 480-0005-00-15 1-3

Chapter 1: Overview

If the network conditions for an IP call become unacceptable—according to the delay and packet loss specifications you configure—Tenor CMS will switch the call to the PSTN automatically and transparently. The T enor CMS continuously monitors your data network for jitter, latency and packet loss, and transparently switches customer calls to the PSTN when required.

Dynamic Call Routing

Tenor CMS’s intelligent call routing capabilities are state-of-the-art. The chassis automatically detects and supports two call types: voice and fax.

Tenor CMS will first identify the call origination site —trunk circuit, line circuit, or IP routing group —and then route the call according to any parameters you configure in the routing database. Each call may be routed via circuit switched path between any two circuit groups, or compressed and transported via VoIP when connecting to an IP routing group. Trunk circuits are those that typically connect to another circuit switched network such as the PSTN. Line circuits typically connect to a termination device on the user premises, such as a PBX.

Multiple Channels/Signaling Supported

Any combination of DS1, or T1 and E1 cards (up to 4) may be used to achieve up to 960 channels. The T enor CMS provides support for most Channel Associated Signaling (CAS) and ISDN protocols.

Fractional T1/E1 Support

Tenor CMS supports Fractional T1/E1.

Chapter 1: Overview

PacketSaver™

PacketSaver packet multiplexing technology reduces the amount of IP bandwidth required to support multiple calls flowing between two endpoints. PacketSaver minimizes bandwidth usage by aggregating samp les 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.

Conventional V oIP Transmission Sends Many Redundant Packet Headers

Tenor using PacketSaver to Minimize Bandwidth Usage

Tenor CMS

IVR/RADIUS support

Interactive Voice Response (IVR) is a feature of the Tenor CMS that enables you to offer services, such as Prepaid calling cards and Post-paid accounts, to your customers.

The Tenor CMS uses the RADIUS (Remote Authentication Dial-In User Service), for authenticating and authorizing user access to the VoIP network, including ANI Authentication (T ypes 1 and 2). The RADIUS is a standard protocol which provides a series of standardized message formats for transmitting and receiving dialed information, account data and authorization codes between the network access gateway and the billing server. As a result, the RADIUS enables the Tenor CMS to interoperate directly with billing server application software from a wide range of vendors. To provide redundancy, the Tenor supports two RADIUS servers: Primary and Secondary.

Easy Connect to Console

Plugging a serial cable (for CPU) or null modem cable (for System Controller) between the System Controller/CPU card’s asynchronous RS-232 port and a serial port of your PC, will allow local chassis management. Through the console connection, you are able to assign an IP address. In addition, if you are directly connected to the chassis, you are able to configure that chassis via Command Line Interface (CLI).

H.323 Gatekeeper Call Control Management

The Tenor CMS chassis’s built-in H.323 gatekeeper performs IP call routing functions, such as call control and administrative services to another Tenor CMS unit, or another H.323 endpoint. The gatekeeper’s functionality complies with the H.323 industry specifications for voice control and management. See H.323 Gate- keeper Services, later in this chapter, for more information.

Chapter 1: Overview

Powerful System Monitoring

There are many different ways to monitor the health of the unit, including LEDs and alarms. LEDs appear on the front of the unit (for CMS -14 slot) and the front of WAN interface cards, as well as on the DSP cards, and the System Controller/CPU card. The LEDs light up according to operations and alarms the system is experiencing. Through the Command Line Interface (CLI) management system, you can view a list of active system alarms, as well as view an alarm history. Each alarm indicates the chassis’s operational status. Tenor CMS is also SNMP-capable with HP® Openview™ support.

Chapter 1: Overview

Data Network Calls

Calls coming from the data network can be routed to the Line circuit or Trunk circuit spans. The Tenor CMS will route calls based upon the dialed number. If the number is configured as a local phone number, the call will be sent to a Line circuit for termination, otherwise the call is considered a “Hop-Off call” and the Tenor CMS sends it out through a Trunk circuit span, typically connected to the PSTN.

Other Call Routing Options

There are several routing tables you can configure via the Command Line Interface (CLI) to adjust how the Tenor CMS unit routes specific calls. For example, you may want to configure 911 as a “bypass number”, which means that all 911 calls coming into Tenor CMS from the line circuit will be routed directly to a Trunk circuit presumably connected to a PSTN. Bypass calls are never routed over IP.

There are four types of routing databases you can configure: Bypass Directory Numbers (BPN), Local Directory Numbers (LDN), Hop-Off Directory Numbers (HDN) and Static Route. Bypass Directory Numbers are directly routed from a Line circuit to a Trunk circuit. Local Directory Numbers are phone numbers that are reachable through local Line Circuits. Hop-Off Directory Numbers are phone numbers that can be routed over the IP to another Tenor location and then out to the Trunk circuit, possibly to the PSTN as a local call. Static Routes are used between networks and other H.323 devices that are not registered to the network through the Border Element (such as non-Quintum gateways).

Virtual Tie Line

Tenor CMS can emulate a 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.

Your PBX does not need any additional configuration. Tenor CMS treats all the trunks the same without compromising voice quality.

Chapter 1: Overview

Hop-off PBX Call

Hop-off numbers are phone number patterns for calls to be routed out trunks. They are entered in a HopoffNumberDirectory and associated with TrunkCircuitRoutingGroups that govern the trunks where matching calls should be sent.

Tenor CMS supports those Hop-off PBX calls where the destination Tenor CMS is programmed to route the call to the PSTN via Trunk Circuit. (A Hop-off PBX call is a toll call which hops through a private network to reduce or eliminate the toll charge.) The destination Tenor CMS unit is configured with the phone numbers to be “supported” for this feature.

SNMP Support

The Tenor CMS unit supports Simp le Network Management Protocol (SNMP), the standard protocol used to exchange network information between different types of networks. The Tenor CMS unit acts as an SNMP agent—using HP Openview—to receive commands and issue responses to the network manager . The network manager will then be able to perform certain functions, such as receiving traps from Tenor CMS.

Call Detail Recording

Through the Call Detail Record (CDR) feature, the Tenor CMS may generate a call record at the completion of each call, typically for accounting purposes. A CDR is a string of data that contains call information such as call date and time, call duration, calling party, and called party. Tenor CMS may store call detail records locally or they can be sent to a CDR server within the network. The CDR contains sufficient information to capture billing data, which can be used to create billing reports by third party billing software.

Chapter 1: Overview

H.323 Gatekeeper Services

Gatekeeper

A Gatekeeper in an H.323 network provides call control services and other services to H.323 endpoints (i.e., gateways, terminals, and MCUs). The Tenor CMS has a built-in H.323 gatekeeper which complies to the H.323 industry specifications for voice control and management. The gatekeeper performs call routing functions for calls entering and exiting a site.

The Gatekeeper performs IP call routing functions, such as call control signaling and call authorization for Gateways, IP phones, and H.323 terminals. The Gatekeeper communicates with other Gatekeepers through a Border Element. When using a group of Tenor CMS units, you can assign one unit as the Gatekeeper for the network. We recommend you configure each CMS as its own gatekeeper.

Tenor CMS supports gatekeeper to gatekeeper communication using LRQ (Location Request) messaging scheme.

Zone Management

A zone is a group of H.323 defined endpoints controlled by a Gatekeeper. Endpoints can be gateways (i.e., Tenor CMS), terminals, and/or multipoint conferencing units (MCU s). Endpoints establish control channels with a gatekeeper for registration, admission, security, and call routing information about the endpoint is sent to the gatekeeper, including: IP address, unit type (gateway, terminal, or MCU) and routing information (such as phone numbers, number patterns, etc.).

A collection of zones is an administrative domain. An administrative domain provides call routing services for its zones through gatekeeper to gatekeeper messages or gatekeeper to border element messages (see Border Element” for more information).

Call Registration

H.323 endpoints in the same zone register with the designated gatekeeper. When registration is complete and a call is originated, the call request is sent to the gatekeeper. The call request provides the Gatekeeper with the dialed number and requests the routing information. The gatekeeper confirms the dialed number and supplies the endpoint with the destination IP address. For example, a Tenor CMS’s gatekeeper will act as the gatekeeper for that zone and all of the other endpoints will register with it.

Border Element

The T enor CMS’ s gatekeeper uses a border element to gain access to the routing database of the administrative domain for the purpose of call completion or any other services that involve communications with other endpoints out of the administrative domain. The border element functionality is built into the Tenor CMS unit, along with the gateway and gatekeeper.

The primary function of the border element is to collect, manage, and distribute call routing information. A gatekeeper will establish a service relationship with a border element; the gatekeeper provides its zones capabilities and the border element shares call routing capabilities of other zones in the administrative domain. Through the border element, gatekeepers from multiple zones will be able to communicate.

A border element also establishes relationships with other border elements to route between administrative domains. If a gatekeeper cannot resolve an address, it contacts the border element.

P/N 480-0005-00-15 1-11

Chapter 1: Overview

In addition, if you are using more than one CMS unit, you can configure one of the border elements for that zone. The T enor CMS unit provides two border elements: primary and secondary. These work together as one entity to provide redundancy and fault tolerance; there are no hierarchical differences.

Call Services

Gatekeepers provide services such as addressing, authorization and authentication of terminals and gateways, bandwidth management, accounting, billing, and charging. Gatekeepers also provide call-routing services. Specifically, the Tenor CMS Gatekeeper provides the functions which follow:

Address Translation. The gatekeeper translates telephone numbers into IP addresses and vice versa. It performs Alias Address (phone number) to Transport Address (IP address) translation when an endpoint requests service. The Gatekeeper uses a translation table to translate an Alias Address (an address such as an H.323 identifier that a user may not understand) to a transport address. The translation table is updated using Registration messages.

Autodiscovery. The gatekeeper is discovered in one of the following ways: An endpoint sends an IP broadcast called a Gatekeeper Request message (GRQ) message (which includes that correct gatekeeper name) to discover a Gatekeeper OR the endpoint will discover a gatekeeper by its IP address.

Routing. The gatekeeper identifies the IP address of endpoints in its administrative domain. The gatekeeper builds a routing database from information obtained from the border element and also from gateways and H.323 endpoints.

Admissions Control. All H.323 endpoints must register and request permission to enter the gatekeeper’s zone; the gatekeeper will confirm or deny access to the network. The gatekeeper authorizes network access and protects the integrity of the network using Admissions Request (ARQ), Admissions Confirmation (ACF) and Admissions Reject (ARJ) messages.

Configuration

For the Gatekeeper/Border Element functionality, the following items are configurable via Command Line Interface (CLI):

• Primary Border Element IP Address. The IP address for the administrative domain’s Border Element

(the Border Element is internal to the Tenor CMS unit; it is used to establish relationships with other

P/N 480-0005-00-15 1-12

Chapter 1: Overview

T enor CMS units in other companies). There is generally only one Primary Border Element in each organization.

• Secondary Border Element IP Address. The IP address for the alternate border element (the IP address

the Tenor CMS uses as a Border Element) is in the administrative zone. There is generally only one secondary Border Element in each organization.

• Discovery IP Address. The IP address a T enor CMS uses to communicate with a Gatekeeper for service.

• Discovery Port. The H.323 standard port a Tenor CMS uses to discover a Gatekeeper.

• Registration Port. The H.323 standard port a Tenor CMS uses to register itself with a Gatekeeper.

Hardware Description

Tenor CMS is available in CMS (14 slot), CMS960 (8 slot), and a CMS240 (2 slot).

The CMS (14 slot), CMS960 (8 slot), and CMS240 (2 slot) provide network connection and functionali ty through WAN cards, DSP resource cards, and a system controller card/CPU card. Communication through the chassis backplane is achieved through the following: packet bus and TDM bus. The packet bus is used for carrying packet-oriented data and the TDM bus is used for transporting circuit switched PCM traffic.

For the AC unit, the front side of the chassis provides access to WAN cards (T1/E1/DS1), power supplies, the system controller card/CPU card, and DSP card; the rear side exposes the back portion of the transition cards for network connection as well as power cord connection.

For the DC unit, the front side of the chassis provides access to WAN cards (T1/E1/DS1), DSP cards, the system controller/CPU card and power supplies. The rear side exposes the back portion of the transition cards for network connections, as well as the circuit breakers, power receptacles and power plugs.

Through all of these units, you can connect up to four different points: Line Circuit (PBX), Trunk Circuit (PSTN), Data network (Ethernet LAN) and a PC.
