What Features are Supported on the Cisco Unified IP Phone 7931G?

The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive telephone calls. In addition to traditional telephony features, the Cisco Unified IP Phone includes features that enable you to administer and monitor the phone as a network device.

This section includes the following topics:

• Feature Overview, page 1-10

• Configuring Telephony Features, page 1-11

• Configuring Network Parameters Using the Cisco Unified IP Phone,

page 1-12

• Providing Users with Feature Information, page 1-12

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing, speed dialing, conference calling, and voice messaging system access. Cisco Unified IP phones also provide a variety of other features. For an overview of the telephony features that the Cisco Unified IP Phone supports, see the “Telephony Features Available for the

Phone” section on page 5-2.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure on a phone, but if your network requires it, you can manually configure an IP address, TFTP

server, and subnet mask. For instructions on configuring the network settings on the Cisco Unified IP Phones, see Chapter 4, “Configuring Settings on the Cisco

Unified IP Phone.”

The Cisco Unified IP Phone can interact with other services and devices on your IP network to provide enhanced functionality. For example, you can integrate the Cisco Unified IP Phones with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for co-workers contact information directly from their IP phones. You can also use XML to enable users to access information such as weather, stocks, quote of the day, and other web-based information. For information about configuring such services, see the “Configuring Corporate Directories” section on page 5-19 and the

“Setting Up Services” section on page 5-22.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status information from it directly. This information can assist you with troubleshooting any problems users might encounter when using their IP phones. See Chapter 7, “Viewing Model Information, Status, and Statistics on the Cisco

Unified IP Phone,” for more information.

Understanding Security Features for Cisco Unified IP Phones

Implementing security in the Cisco Unified Communications Manager system prevents identity theft of the phone and Cisco Unified Communications Manager server, prevents data tampering, and prevents call signaling and media stream tampering.

To alleviate these threats, the Cisco IP telephony network establishes and maintains authenticated and encrypted communication streams between a phone and the server, digitally signs files before they are transferred to a phone, and encrypts media streams and call signaling between Cisco Unified IP phones.

Table 1-3 Overview of Security Features

Feature Description

Image authentication Signed binary files (with the extension .sbn) prevent tampering with

the firmware image before it is loaded on a phone. Tampering with the image causes a phone to fail the authentication process and reject the new image.

Customer-site certificate installation

Each Cisco Unified IP Phone requires a unique certificate for device authentication. Phones include a manufacturing installed certificate (MIC), but for additional security, you can specify in Cisco Unified Communications Manager Administration that a certificate be installed by using the CAPF

. Alternatively, you can install an LSC from the Security Configuration menu on the phone. See the

“Configuring Security on the Cisco Unified IP Phone” section on page 3-13 for more information.

Device authentication Occurs between the Cisco Unified Communications Manager server

and the phone when each entity accepts the certificate of the other entity. Determines whether a secure connection between the phone and a Cisco Unified Communications Manager should occur, and, if necessary, creates a secure signaling path between the entities using TLS protocol. Cisco Unified Communications Manager will not register phones unless they can be authenticated by the Cisco Unified Communications Manager.

File authentication Validates digitally-signed files that the phone downloads. The

phone validates the signature to make sure that file tampering did not occur after the file creation. Files that fail authentication are not written to Flash memory on the phone. The phone rejects such files without further processing.

Signaling Authentication Uses the TLS protocol to validate that no tampering has occurred to

Manufacturing installed certificate

signaling packets during transmission.

Each Cisco Unified IP Phone contains a unique manufacturing installed certificate (MIC), which is used for device authentication. The MIC is a permanent unique proof of identity for the phone, and allows Cisco Unified Communications Manager to authenticate the phone.

Feature Description

Secure SRST reference After you configure a SRST reference for security and then reset the

dependent devices in Cisco Unified Communications Manager Administration, the TFTP server adds the SRST certificate to the phone cnf.xml file and sends the file to the phone. A secure phone then uses a TLS connection to interact with the SRST-enabled router.

Media encryption Uses SRTP to ensure that the media streams between supported

devices proves secure and that only the intended device receives and reads the data. Includes creating a media master key pair for the devices, delivering the keys to the devices, and securing the delivery of the keys while the keys are in transport.

Signaling encryption Ensures that all SCCP signaling messages that are sent between the

device and the Cisco Unified Communications Manager server are encrypted.

CAPF (Certificate Authority Proxy Function)

Implements parts of the certificate generation procedure that are too processing-intensive for the phone, and it interacts with the phone for key generation and certificate installation. The CAPF can be configured to request certificates from customer-specified certificate authorities on behalf of the phone, or it can be configured to generate certificates locally.

Security profiles Defines whether the phone is nonsecure, authenticated, or

encrypted. See the “Understanding Security Profiles” section on

page 1-19 for more information.

Encrypted configuration files Lets you ensure the privacy of phone configuration files.

Optional disabling of the web server functionality for a phone

You can prevent access to a phone’s web page, which displays a variety of operational statistics for the phone.

Identifying Encrypted and Authenticated Phone Calls

When security is implemented for a phone, you can identify authenticated or encrypted phone calls by icons on the screen on the phone.

In an authenticated call, all devices participating in the establishment of the call are authenticated by the Cisco Unified Communications Manager. When a call in progress is authenticated, the call progress icon to the right of the call duration timer in the phone screen changes to this icon:

In an encrypted call, all devices participating in the establishment of the call are authenticated by the Cisco Unified Communications Manager. In addition, call signaling and media streams are encrypted. An encrypted call offers the highest level of security, providing integrity and privacy to the call. When a call in progress is being encrypted, the call progress icon to the right of the call duration timer in the phone screen changes to this icon: .

Establishing and Identifying Secure Conference Calls

You can initiate a secure conference call and monitor the security level of participants. A secure conference call is established using this process:

1. A user initiates the conference from a secure phone (encrypted or

authenticated security mode).

2. Cisco Unified Communications Manager assigns a secure conference bridge

to the call.

3. As participants are added, Cisco Unified Communications Manager verifies

the security mode of each phone (encrypted or authenticated) and maintains the secure level for the conference.

4. The phone displays the security level of the conference call. A secure

conference displays (encrypted) or

(authenticated) icon to the right

of “Conference” on the phone. If the icon displays, the conference is not secure.

Note There are interactions, restrictions, and limitations that affect the security level of

the conference call depending on the security mode of the participants’ phones and the availability of secure conference bridges. See Tab le 1-4 and Tabl e 1 -5 for information about these interactions.

Supporting 802.1X Authentication on Cisco Unified IP Phones

These sections provide information about 802.1X support on the Cisco Unified IP Phone:

• Overview, page 1-23

• Required Network Components, page 1-24

• Best Practices—Requirements and Recommendations, page 1-24

Overview

Cisco Unified IP phones and Cisco Catalyst switches have traditionally used Cisco Discovery Protocol (CDP) to identify each other and to determine parameters such as VLAN allocation and inline power requirements. However, CDP is not used to identify any locally attached PCs. Therefore, Cisco Unified IP Phones provide an EAPOL pass-through mechanism, whereby a PC locally attached to the IP phone may pass through EAPOL messages to the 802.1X authenticator in the LAN switch. This capability prevents the IP phone from having to act as the authenticator, yet allows the LAN switch to authenticate a data end point prior to accessing the network.

In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP Phones provide a proxy EAPOL-Logoff mechanism. If the locally attached PC is disconnected from the IP phone, the LAN switch would not see the physical link fail, because the link between the LAN switch and the IP phone is maintained. To avoid compromising network integrity, the IP phone sends an EAPOL-Logoff message to the switch on behalf of the downstream PC, which triggers the LAN switch to clear the authentication entry for the downstream PC.

The Cisco Unified IP phones contain an 802.1X supplicant in addition to the EAPOL pass-through mechanism. This supplicant allows network administrators to control the connectivity of IP phones to the LAN switch ports. The initial release of the IP phone 802.1X supplicant implements the EAP-MD5 option for

802.1X authentication.

Understanding Security Features for Cisco Unified IP Phones

Required Network Components

Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:

• Cisco Unified IP Phone—The phone acts as the 802.1X supplicant, which

initiates the request to access the network.

• Cisco Secure Access Control Server (ACS) (or other third-party

authentication server)—The authentication server and the phone must both be configured with a shared secret that is used to authenticate the phone.

• Cisco Catalyst Switch (or other third-party switch)—The switch must support

802.1X so it can act as the authenticator and pass the messages between the phone and the authentication server. When the exchange is completed, the switch grants or denies the phone access to the network.

Chapter 1 An Overview of the Cisco Unified IP Phone

Best Practices—Requirements and Recommendations

• Enable 802.1X Authentication—If you want to use the 802.1X standard to

authenticate Cisco Unified IP Phones, make sure that you have properly configured the other components before enabling it on the phone. See the

“802.1X Authentication and Status” section on page 4-39 for more

information.

• Configure PC Port—The 802.1X standard does not take into account the use

of VLANs and thus recommends that only a single device be authenticated to a specific switch port. However, some switches (including Cisco Catalyst switches) support multi-domain authentication. The switch configuration determines whether you can connect a PC to the phone PC port.

–

Enabled—If you are using a switch that supports multi-domain authentication, you can enable the PC port and connect a PC to it. In this case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor the authentication exchanges between the switch and the attached PC. For more information about IEEE 802.1X support on the Cisco Catalyst switches, refer to the Cisco Catalyst switch configuration guides at:

http://www.cisco.com/en/US/products/hw/switches/tsd_products_ support_category_home.html

–

Disabled—If the switch does not support multiple 802.1X-compliant devices on the same port, you should disable the PC Port when 802.1X authentication is enabled. See the “Security Configuration Menu” section

Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified Communications Manager 6.0

OL-12457-01

Page 43

Chapter 1 An Overview of the Cisco Unified IP Phone

on page 4-28 for more information. If you do not disable this port and

subsequently attempt to attach a PC to it, the switch will deny network access to both the phone and the PC.

• Configure Voice VLAN—Because the 802.1X standard does not account for

VLANs, you should configure this setting based on the switch support.

–

Enabled—If you are using a switch that supports multi-domain authentication, you can continue to use the voice VLAN.

–

Disabled—If the switch does not support multi-domain authentication, disable the Voice VLAN and consider assigning the port to the native VLAN. See the “Security Configuration Menu” section on page 4-28 for more information.

• Enter MD5 Shared Secret—If you disable 802.1X authentication or perform

a factory reset on the phone, the previously configured MD5 shared secret is deleted. See the “802.1X Authentication and Status” section on page 4-39 for more information.

Understanding Security Features for Cisco Unified IP Phones

Security Restrictions

A user cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a reorder tone (fast busy tone) plays on the phone on which the user initiated the barge.

If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified Communications Manager classifies the call as nonsecure.

If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.

A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to appear on the authenticated devices in the call, even if the initiator phone does not support security.

Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco Unified Communications Manager software sets up and tears down calls between phones, integrating traditional PBX functionality with the corporate IP network. Cisco Unified Communications Manager manages the components of the IP telephony system—the phones, the access gateways, and the resources necessary for such features as call conferencing and route planning. Cisco Unified Communications Manager also provides:

• Firmware for phones

• Authentication and encryption (if configured for the telephony system)

• Configuration file and CTL file, via TFTP service

• Phone registration

• Call preservation, so that a media session continues if signaling is lost

between the primary Communications Manager and a phone

Understanding How the Cisco Unified IP Phone Interacts with the VLAN

The Cisco Unified IP Phone 7931G has an internal Ethernet switch, enabling forwarding of packets to the phone, and to the access port and the network port on the back of the phone.

If a computer is connected to the access port, the computer and the phone share the same physical link to the switch and share the same port on the switch. This shared physical link has the following implications for the VLAN configuration on the network:

• The current VLANs might be configured on an IP subnet basis. However,

additional IP address might not be available to assign the phone to the same subnet as other devices connect to the same port.

• Data traffic present on the data/native VLAN may reduce the quality of

Voice-over-IP traffic.

• Network security may indicate a need to isolate the VLAN voice traffic from

the VLAN data traffic.

Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified Communications Manager 6.0

OL-12457-01

Page 56

Providing Power to the Phone

You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port that the phone is connected to would be configured to have separate VLANs for carrying:

• Voice traffic to and from the IP phone (auxiliary VLAN, on the Cisco Catalyst

• Data traffic to and from the PC connected to the switch through the access

Isolating the phones on a separate, auxiliary VLAN improves the quality of the voice traffic and allows a large number of phones to be added to an existing network where there are not enough IP addresses for each phone.

Power Outage

Your accessibility to emergency service through the phone is dependent on the phone being powered. If there is an interruption in the power supply, Service and Emergency Calling Service dialing will not function until power is restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before using the Service or Emergency Calling Service dialing.

Understanding Phone Configuration Files

Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications Manager that requires the phone to be reset, a change is made to the phone configuration file automatically.

Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified Communications Manager 6.0

2-6

OL-12457-01

Page 59

Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network

Configuration files also contain information about which image load the phone should be running. If this image load differs from the one currently that is loaded on a phone currently, the phone contacts the TFTP server to request the required load files. (These files are digitally signed to ensure the authenticity of the file source.)

In addition, if the device security mode in the configuration file is set to Authenticated and the CTL file on the phone has a valid certificate for Cisco Unified Communications Manager, the phone establishes a TLS connection to Cisco Unified Communications Manager. Otherwise, the phone establishes a TCP connection.

Note If the device security mode in the configuration file is set to Authenticated or

Encrypted, but the phone has not received a CTL file, the phone will continuously try to obtain a CTL file so that it can register securely.

Understanding Phone Configuration Files

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For detailed information, refer to the “Configuring Encrypted Phone Configuration Files” chapter in Cisco Unified Communications Manager Security Guide.

A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when these conditions exist:

• You have enabled auto-registration in Cisco Unified Communications

Manager

• The phone has not been added to the Cisco Unified Communications Manager

Database

• The phone is registering for the first time

If auto registration is not enabled and the phone has not been added to the Cisco Unified Communications Manager Database, the phone registration request will be rejected. In this case, the phone resets and attempts to register repeatedly.

If the phone has registered before, the phone accesses the configuration file named SEPmac_address.cnf.xml, where mac_address is the MAC address of the phone.

If a phone is not using external power, the switch provides in-line power through the Ethernet cable attached to the phone.

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

Cisco switch, the switch next informs the phone of the voice VLAN defined on the switch port. The phone needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.

4. Obtaining an IP

Address

5. Accessing a TFTP

Server

6. Requesting the CTL

file

If the Cisco Unified IP Phone is using DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you are not using DHCP in your network, you must assign static IP addresses to each phone locally.

In addition to assigning an IP address, the DHCP server directs the Cisco Unified IP Phone to a TFTP Server. If the phone has a statically-defined IP address, you must configure the TFTP server locally on the phone; the phone then contacts the TFTP server directly.

Note You can also assign an alternative TFTP

server to use instead of the one assigned by DHCP.

The TFTP server stores the certificate trust list (CTL) file. This file contains a list of Cisco Unified Communications Managers and TFTP servers that the phone is authorized to connect to. It also contains the certificates necessary for establishing a secure connection between the phone and Cisco Unified Communications Manager.

Configuration File

8. Contacting Cisco

Unified Communications Manager

The TFTP server has configuration files, which define parameters for connecting to Cisco Unified Communications Manager and other information for the phone.

The configuration file defines how the Cisco Unified IP Phone communicates with Cisco Unified Communications Manager and provides a phone with its load ID. After obtaining the file from the TFTP server, the phone attempts to make a connection to the highest priority Cisco Unified Communications Manager on the list. If security is implemented, the phone makes a TLS connection. Otherwise, it makes a non-secure TCP connection.

If the phone was manually added to the database, Cisco Unified Communications Manager identifies the phone. If the phone was not manually added to the database and auto-registration is enabled in Cisco Unified Communications Manager, the phone attempts to auto-register itself in the Cisco Unified Communications Manager database.

Adding Phones to the Cisco Unified Communications Manager Database

Adding Phones with Auto-Registration

By enabling auto-registration before you begin installing phones, you can:

• Add phones without first gathering MAC addresses from the phones.

• Automatically add a Cisco Unified IP Phone to the Cisco Unified

Communications Manager database when you physically connect the phone to your IP telephony network. During auto-registration, Cisco Unified Communications Manager assigns the next available sequential directory number to the phone.

• Quickly enter phones into the Cisco Unified Communications Manager

database and modify any settings, such as the directory numbers, from Cisco Unified Communications Manager.

• Move auto-registered phones to new locations and assign them to different

device pools without affecting their directory numbers.

Note Cisco recommends that you use auto-registration to add fewer than 100 phones to

your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT). See the “Adding Phones with BAT” section on

page 2-14.

Auto-registration is disabled by default. In some cases, you might not want to use auto-registration: for example, if you want to assign a specific directory number to the phone or if you plan to implement authentication or encryption, as described in Cisco Unified Communications Manager Security Guide. For information about enabling auto-registration, refer to “Enabling Auto-Registration” in Cisco Unified Communications Manager Administration Guide.

Note When you configure the cluster for mixed mode through the Cisco CTL client,

auto-registration is automatically disabled. When you configure the cluster for non-secure mode through the Cisco CTL client, auto-registration is automatically enabled.

Adding Phones with Auto-Registration and TAPS

You can add phones with auto-registration and TAPS, the Tool for Auto-Registered Phones Support, without first gathering MAC addresses from phones.

TAPS works with the Bulk Administration Tool (BAT) to update a batch of phones that were already added to the Cisco Unified Communications Manager database with dummy MAC addresses. Use TAPS to update MAC addresses and download pre-defined configurations for phones.

Note Cisco recommends that you use auto-registration and TAPS to add fewer than 100

phones to your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT). See the “Adding Phones with BAT” section on

page 2-14.

To implement TAPS, you or the end-user dial a TAPS directory number and follow voice prompts. When the process is complete, the phone will have downloaded its directory number and other settings, and the phone will be updated in Cisco Unified Communications Manager Administration with the correct MAC address.

Auto-registration must be enabled in Cisco Unified Communications Manager Administration (System > Cisco Communications Manager) for TAPS to function.

Note When you configure the cluster for mixed mode through the Cisco CTL client,

auto-registration is automatically disabled. When you configure the cluster for non-secure mode through the Cisco CTL client, auto-registration is automatically enabled.

Refer to Cisco Unified Communications Manager Bulk Administration Guide for detailed instructions about BAT and about TAPS.

Understanding the Cisco Unified IP Phone 7931G Components

Use the SW network port to connect the phone to the network. You must use a straight-through cable on this port. The phone can also obtain inline power from a switch over this connection. See the “Providing Power to the Phone” section on

page 2-4 for details.

Use the PC access port to connect a network device, such as a computer, to the phone. You must use a straight-through cable on this port.

Handset

The handset is designed especially for use with the Cisco Unified IP Phone 7931G. It includes a light strip that indicates incoming calls and voice messages waiting.

To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port on the back of the phone.

Chapter 3 Setting Up the Cisco Unified IP Phone

Note The handset does not support wideband audio.

Speakerphone

Headset

By default, the speakerphone is enabled on the Cisco Unified IP Phone 7931G.

You can disable the speakerphone through the Cisco Unified Communications Manager Administration application. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone Configuration web page for the phone, check the Disable Speakerphone check box.

Although Cisco Systems performs some internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco does not certify or support products from headset or handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed, there is not a single “best” solution that is optimal for all environments. Cisco recommends that customers test the headsets that work best in their environment before deploying a large number of units in their network.

Chapter 3 Setting Up the Cisco Unified IP Phone

In some instances, the mechanics or electronics of various headsets can cause remote parties to hear an echo of their own voice when they speak to Cisco Unified IP Phone users.

Cisco Systems recommends the use of good quality headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and their proximity to other devices such as cell phones and two-way radios, some audio noise may still occur.

The primary reason that support of a headset would be inappropriate for an installation is the potential for an audible hum. This hum can either be heard by the remote party or by both the remote party and the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, being near electric motors, large PC monitors. In some cases, a hum experienced by a user may be reduced or eliminated by using a local power cube.

Understanding the Cisco Unified IP Phone 7931G Components

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound good to the user and the party on the far end. Sound is subjective and Cisco cannot guarantee the performance of any headsets or handsets, but some of the headsets and handsets on the sites listed below have been reported to perform well on Cisco Unified IP Phones.

Nevertheless, it is ultimately still the customer’s responsibility to test this equipment in their own environment to determine suitable performance.

For information about headsets, refer to:

http://www.vxicorp.com/cisco

http://www.plantronics.com

http://www.jabra.com

Connecting a Headset

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the phone. Press the Headset button on the phone to place and answer calls using the headset.

Understanding the Cisco Unified IP Phone 7931G Components

You can use the headset with all of the features on the Cisco Unified IP Phone, including the Volume and Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the headset microphone.

Disabling a Headset

You can disable the headset through the Cisco Unified Communications Manager Administration application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified Communications Manager Administration, choose Device > Phone and locate the phone that you want to modify. In the Phone Configuration web page for the phone, check the Disable Speakerphone and Headset check box.

Using External Devices with Your Cisco Unified IP Phone

The following information applies when you use external devices with the Cisco Unified IP Phone:

Cisco recommends the use of good quality external devices that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF) signals.

Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:

• Move the external device away from the source of the RF or AF signals.

• Route the external device cables away from the source of the RF or AF

signals.

• Use shielded cables for the external device, or use cables with a better shield

and connector.

• Shorten the length of the external device cable.

• Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system will perform adequately when suitable devices are attached using good quality cables and connectors.
