THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

CHAPTER

Overview of the Cisco IP Conference Station 7936

The Cisco IP Conference Station 7936 is an IP-based, hands-free conference station that uses Voice over IP (VoIP) technology. The IP Conference Station replaces a traditional analog conferencing unit by providing business conferencing features, such as Call Hold, Call Resume, Call Transfer, Call Release, Call Pickup, Group Pickup, Redial, Mute, and Conference, over an IP network. Support for G.711 and G.729a audio compression is included.

The IP Conference Station works with several other key Cisco IP Telephony components, including Cisco CallManager.

The following topics in this chapter provide information about the IP Conference Station and its interaction with other key components of the VoIP network.

Chapter 1 Overview of the Cisco IP Conference Station 7936

Networking Protocols

The IP Conference Station supports several industry-standard and Cisco networking protocols required for voice communication. See the following table for an overview of the supported networking protocols.

Networking Protocol Purpose Usage Notes

Cisco Discovery Protocol (CDP) CDP is a device-discovery

protocol that runs on all Cisco-manufactured equipment.

Using CDP, a device can advertise its existence to other devices and receive information about other devices in the network.

Dynamic Host Configuration Protocol (DHCP)

DHCP dynamically allocates and assigns an IP address to network devices.

DHCP enables you to connect the IP phone into the network and become operational without manually assigning an IP address and configuring additional required network parameters.

The IP Conference Station uses CDP to communicate configuration information to the Cisco Catalyst switch. With CDP, each device sends periodic messages to a multicast address and in turn listens to the periodic messages sent by other devices. This allows devices on the network to discover one another and learn information such as protocols used, protocol addresses, and so on.

DHCP is enabled by default. If disabled, you must manually configure the IP address, subnet mask, gateway, and TFTP server on each station.

1-2

Cisco IP Conference Station 7936 Administration Guide

OL-4746-01

Chapter 1 Overview of the Cisco IP Conference Station 7936

Networking Protocol Purpose Usage Notes

Internet Protocol (IP) IP is a messaging protocol that

addresses and sends packets across the network.

Real-Time Transport (RTP) RTP is a standard for

transporting real-time data, such as interactive voice and video over data networks.

Skinny Client Control Protocol (SCCP)

Skinny Client Control Protocol. A Cisco protocol using lowbandwidth messages that allows communication between IP devices and the Cisco CallManager.

Transmission Control Protocol (TCP)

Trivial File Transfer Protocol (TFTP)

TCP is a a connection-oriented transport protocol.

TFTP allows you to transfer files over the network.

On the IP Conference Station, TFTP enables you to obtain a configuration file specific to the IP Conference Station type.

To communicate using IP, network devices must have an assigned IP address, subnet, and gateway.

IP addresses, subnets, and gateways identifications are automatically assigned if you are using the IP Conference Station with DHCP. If you are not using DHCP, you must manually assign these properties to each station locally.

The IP Conference Station can collect and process RTP traffic from routers, hubs, and switches.

The IP Conference Station uses SCCP to communicate with the Cisco CallManager.

The IP Conference Station uses TCP to connect to Cisco CallManager.

TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If more than one TFTP server is running in your network, you must manually assign a TFTP server to each station locally.

Chapter 1 Overview of the Cisco IP Conference Station 7936

Supported Features

Networking Protocol Purpose Usage Notes

User Datagram Protocol (UDP) UDP is a connectionless

messaging protocol for delivery of data packets.

Voice over IP (VoIP) VoIP enables you to transfer

voice communications over a data network using the Internet Protocol.

The IP Conference Station receives and processes UDP messages.

The IP Conference Station connects to the PSTN through a VoI P g atew ay.

Supported Features

The IP Conference Station functions much like the traditional analog conferencing unit allowing you to set up and place conference calls and receive calls. The IP Conference Station also supports features such as call hold, redial, and mute.

In addition to these traditional telephony features, the IP Conference Station also includes features enabling you to administer and monitor it as an IP networking device. On the IP Conference Station, you can locally configure features such as DHCP, TFTP, and IP settings.You can also integrate the IP Conference Station with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for co-workers’ contact information directly from the IP Conference Station. From Cisco CallManager, you can modify additional settings, which are viewable from the IP Conference Station’s network configuration settings. Use this guide for information about configuring these settings.

Available Connections

The IP Conference Station includes the following connections for accessing the data network and providing power to the station:

• Power Interface Module (PIM) for connection between the

IP Conference Station and the network.

• A single RJ-45 connector for accessing the data network and connecting to

the PIM, which provides power to the IP Conference Station.

Understanding Interactions with Other Cisco IP Telephony Products

To function in the IP telephony network, the IP Conference Station must be connected to a networking device, such as a Cisco Catalyst switch, in order to obtain network connectivity. The IP Conference Station must also be registered with a Cisco CallManager system in order to make and receive calls.

Understanding How the IP Conference Station Interacts with Cisco CallManager

Cisco CallManager is an open and industry-standard call processing system. Cisco CallManager software runs on a Windows 2000 server and sets up and tears down calls between phones, integrating traditional PBX functionality with the corporate IP network. Cisco CallManager manages the components of the IP telephony system, the conference stations, the phones, access gateways, and the resources necessary for such features as call conferencing and route planning.

For information about configuring Cisco CallManager to work with the IP devices described in this chapter, refer to the Cisco CallManager Administration Guide and the Cisco CallManager System Guide.

Understanding the Startup Process

When connecting to the VoIP network, the IP Conference Station goes through a standard startup process.

Understanding the Startup Process

Loading the Stored Station Image

The IP Conference Station has non-volatile Flash memory in which it stores firmware images and user-defined preferences. At startup, the IP Conference Station runs a bootstrap loader that loads a station image stored in Flash memory. Using this image, the station initializes its software and hardware.

Configuring VLAN

If the IP Conference Station is connected to a Cisco Catalyst switch, the switch next informs the conference station of the voice virtual local area network (VLAN) defined on the switch. The IP Conference Station needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.

Obtaining an IP Address

If the IP Conference Station is using DHCP to obtain an IP address, the station queries the DHCP server to obtain one.

Accessing TFTP Server

In addition to assigning an IP address, the DHCP server also points the IP Conference Station to a TFTP server. You must configure option 150 on the DHCP server for the TFTP information to be passed from the server to the client.

If the IP Conference Station has a statically-defined IP address, you must manually configure the IP address of an alternate TFTP server; the IP Conference Station uses this alternate TFTP server to receive its information.

Requesting the Configuration File

Configuration files (.cnf file format) for each telephony device, which define connection parameters for Cisco CallManager, are stored on the TFTP server.

If you have enabled auto-registration in Cisco CallManager, the IP Conference Stations access a default configuration file (XMLDefault.cnf.xml) from the TFTP server. If you have manually entered the IP Conference Stations into the Cisco CallManager database, each station accesses an .xml file corresponding to its device name.
