Cisco Product Security Overview
Cisco Product Security Overview
Cisco provides a free online Security Vulnerability Policy portal at this URL:
http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html
From this site, you can perform these tasks:
• Report security vulnerabilities in Cisco products.
• Obtain assistance with security incidents that involve Cisco products.
• Register to receive security information from Cisco.
A current list of security advisories and notices for Cisco products is available at this URL:
http://www.cisco.com/go/psirt
If you prefer to see advisories and notices as they are updated in real time, you can access a Product
Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:
http://www.cisco.com/en/US/products/products_psirt_rss_feed.html
Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:
• Emergencies—security-alert@cisco.com
• Nonemergencies — psirt@cisco.com
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive
information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence
with PSIRT is the one that has the most recent creation date in this public key server list:
http://pgp.mit.edu:11371/pks/lookup?search=psirt%40cisco.com&op=index&exact=on
In an emergency, you can also reach PSIRT by telephone:

Preface
Obtaining Technical Assistance
Cisco Technical Support Website
The Cisco Technical Support Website provides online documents and tools for troubleshooting and
resolving technical issues with Cisco products and technologies. The website is available 24 hours a day,
365 days a year, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password.
If you have a valid service contract but do not have a user ID or password, you can register at this URL:
http://tools.cisco.com/RPF/register/register.do
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting
a web or phone request for service. You can access the CPI tool from the Cisco Technical Support
Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product
Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product
Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID
or model name; by tree view; or for certain products, by copying and pasting show command output.
Search results show an illustration of your product with the serial number label location highlighted.
Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447
For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.

Preface
Obtaining Additional Publications and Information
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
Obtaining Additional Publications and Information

About the Cisco IPVC 3540 PRI Gateway
The Cisco IPVC 3540 PRI Gateway consists of two modules that insert into a Cisco IPVC 3544 chassis:
the Cisco IPVC 3540 PRI Gateway module and the Rear Transition Module (RTM). The gateway
module installs in the front of the chassis and contains the gateway application apparatus. The RTM
installs in the rear of the chassis and contains the physical interface that connects to the PRI-service
provider equipment. You must install the gateway module and the RTM in corresponding slots. For
example, if you install the gateway module in slot 2 in the front of the chassis, you must install the RTM
in slot 2 in the rear of the chassis.
The Cisco IPVC 3544 chassis requires that the module installed in the top slot provide the system
controls for the cPCI bus. The gateway module has system capability, and can be installed in top slot of
the chassis or in one of the other slots. When you install a gateway module in the top slot, you must
replace the original RTM in the top slot in the rear of the chassis with a gateway RTM.

Chapter 1 Overview of the Cisco IPVC 3500 Series Gateway
About Cisco IPVC 3500 Series Gateway Features
ISDN rollover The Cisco IPVC 3500 Series Gateway features
ISDN rollover. In this feature, the gateway sends
a “busy out” channel request to the PSTN switch
when the current PRI connection is left with less
than a predefined number of available B channels.
The PSTN switch “rolls over” to the next
available gateway.
Note This feature is supported on the
CiscoIPVC3500PRIGateways only.
Network Specific Facility The Cisco IPVC 3500 Series Gateway provides
support for Network Specific Facility Information
Elements (NSF IEs) enables system
administrators to specify to service providers the
equipment, service, or network through which
they want a call routed.
Note This feature is supported on the
CiscoIPVC3500PRIGateways only.
ISDN connection failure The Cisco IPVC 3500 Series Gateway responds
to ISDN connection failure events, by
unregistering from its gatekeeper. The gatekeeper
is forced to send new IP-to-ISDN calls through a
different gateway, thus ensuring high call
completion rates. The gateway re-registers to the
gatekeeper when the ISDN connection is restored.
Downspeeding The Cisco IPVC 3500 Series Gateway features In
downspeeding functionality. In the downspeeding
feature, the Cisco IPVC 3500 Series Gateway
attempts to reconnect a disconnected video call
either at a lower bandwidth or as a voice call.

Figure 1-8 Multimedia Conferencing through the Gateway
About Multipoint Conferencing
Together with the Cisco IPVC 35xx MCU, the Cisco IPVC 3500 Series Gateway enables H.320 ISDN
terminals to participate in a mixed ISDN-IP multipoint multimedia conference with IP network
endpoints (see Figure 1-9).
For example, when an H.320 ISDN terminal wants to participate in a multipoint conference with H.323
IP endpoints, the H.320 ISDN terminal can either join the multipoint conference by dialing to the
gateway, or be invited into the conference by one of the participating IP endpoints. In either case, the
gateway connects the ISDN terminal to the Cisco IPVC 35xx MCU enabling it to participate in the
multipoint conference.

Note Enabling ISDN-to-IP DTMF detection in the Cisco IPVC 3526 PRI Gateway for video calls reduces the
number of supported calls by half.
About Cisco IPVC 3500 Series Gateway Call Bandwidth Overhead
According to the H.320 standard, the available bandwidth allocated to a call at any given bit rate will
always be slightly less than the stated maximum for the following reasons:
• All stated maximum call bandwidths include provision for control, audio, video, and data traffic.
• Video traffic on the ISDN side contains additional bits for error correction purposes which also
consume bandwidth. Video traffic on the IP side does not include this additional load.
• Opening an audio channel further reduces the bandwidth available to the video traffic.
For example, a call at 384 Kbps actually has only 363 Kbps available to it. Control and error correction
account for the remaining 21 Kbps
About Peer-to-Peer Connectivity
The Cisco IPVC 3500 Series Gateway supports the following types of connectivity to the IP network
• Through a gatekeeper
• Directly to a peer device such as Cisco CallManager without the need for a gatekeeper.

Preparing for Installation of the Cisco IPVC 3521 BRI Gateway
Preparing for Installation of the Cisco IPVC 3521 BRI Gateway
The Cisco IPVC 3521 BRI Gateway prepares the signaling for outbound videoconference calls that are
transmitted over Integrated Services Digital Network (ISDN) networks. For videoconference information
to arrive at its destination, you must work with the BRI service provider to ensure that the gateway and
the ISDN service are compatible. You must gather information about the service provider equipment and
provide the service provider with information about the gateway.
Before you order BRI service or connect the Cisco IPVC 3521 BRI Gateway to your existing BRI
service, we suggest that you gather the following information.
1. Identify the ISDN provider you want to use as your Local Exchange Carrier (LEC) for local calls.
Note The LEC is the local telephone company that provides ISDN services for your local calling
area and to which your equipment connects.
2. Identify the ISDN provider you want to use as your Interexchange Carrier (IEC) for long-distance
calls.
Note The IEC and the LEC are different companies. Often the LEC will contact the IEC and
provision long-distance service for you. Verify that your LEC performs this task, and contact
an IEC if the LEC does not.
3. Determine how many BRI lines you want to connect to the gateway.
4. Identify the ISDN equipment or signaling format your LEC uses.
5. Determine whether you want to use layer 1 line hunting.
6. Have your ISDN service provider turn off the following switch settings:
• Packet Mode Data on the D channel
• Terminal Display Text
• EKTS
• Call Appearances
• Key Hold
• ACO
Preparing for Installation of the Cisco IPVC 3500 PRI Gateways
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch
the backplane with your hand or any metal tool, or you could shock yourself.
The following are necessary for installing a Cisco IPVC 3500 PRI Gateway:

Installing the Cisco IPVC 3540 PRI Gateway
The Cisco IPVC 3540 PRI Gateway has two components that you must install in the
Cisco IPVC 3544 chassis: the Cisco IPVC 3540 PRI Gateway module and the PRI rear transition
module (RTM). These modules complement each other. The gateway module installs in the front of the
chassis and provides PRI functionality. The RTM installs in the rear of the chassis and provides the
physical interface for the PRI line. You must install these modules in corresponding slots in the chassis.
That is, if you insert the gateway module in the top slot in the front of the chassis, you must insert the
RTM in the top slot in the rear of the chassis.
The Cisco IPVC 3544 chassis uses a cPCI bus and requires a module with system functionality in the
top slot. This system functionality is embedded in the gateway module and is activated only when the
gateway module is installed in the top slot.

Installing the Cisco IPVC 3540 PRI Gateway
Caution Cisco IPVC 3540 modules contain ESD-sensitive components. Use proper ESD procedures when
handling the modules. Improper handling can damage the module and cause the module to fail
immediately or at a later time.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning
Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Before opening the chassis, disconnect the telephone-network cables to avoid contact with
telephone-network voltages.
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Warning
The telecommunications lines must be disconnected 1) before unplugging the main power connector
and/or 2) while the housing is open.
Installing the PRI RTM in the Cisco IPVC 3544 Chassis Top Slot
The top slot in the Cisco IPVC 3544 chassis is used to provide system functionality to the cPCI bus. This
functionality is embedded in the gateway module which connects to the bus through the RTM. This
section describes how to install the RTM in the chassis top slot to allow the gateway module to
communicate with the cPCI bus.
Procedure:
Step 1 Disconnect the power cable to the chassis to ensure that the power is turned off.
Step 2 On the back of the chassis, loosen the screws that secure the latches of the top cover panel.
Step 3 Press the red release button and snap the black handles back to open the latches.
Step 4 Slide the RTM out two inches to expose the cable.
Step 5 Remove the 16-pin flat cable attached to the board.
We recommend that you place the blade of a small, flat-blade screwdriver at the base of the cable
connector key, and pry the connector upward to remove the cable.
Caution Damaging the cable results in the LEDs on the chassis not working.
Step 6 Remove the RTM from the chassis.

In the Basics section of the Settings tab, you can set the gateway identifier, which is the name that the
gateway uses when registering to a gatekeeper and when dialing to endpoints.
Procedure
Step 1 In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the Settings tab.
Step 3 Click the Basics button (if not already selected).
Step 4 In the Gateway Identifier field, enter the gateway identifier.
Configuring IP Connectivity Settings
In the IP Connectivity section of the Settings tab, you can select the IP connectivity mode in which the
gateway operates, set the address of the gatekeeper with which the gateway registers, and define the way
in which the gateway interacts with the gatekeeper.
You can configure the IP connectivity mode in the following two ways:
• Using a gatekeeper—The gateway registers with a gatekeeper and uses the gatekeeper for every call
(See Configuring the Gateway to Register With a Gatekeeper, page 3-5).
• Peer-to-Peer—The gateway connects directly to a peer device without the need for a gatekeeper.
Peer devices include Cisco CallManager.
Caution Changing the IP connectivity mode setting causes the gateway to reset.

Configuring Gateway Settings
Step 6 In the Gatekeeper address field, make one of the following entries:
a. Enter the IP address of the gatekeeper to which the gateway registers.
—or—
a. Click Browse.
The Discovered Gatekeepers dialog box appears, displaying all gatekeepers located on the same
network segment as the gateway.
b. Select a discovered gatekeeper.
c. Click OK.
Step 7 In the Gatekeeper port field, enter the port number of the gatekeeper. The default setting is 1719.
Step 8 Select the Registration refresh every n seconds check box to set the Time To Live interval (in seconds)
that determines how often the gateway sends a “keep alive” message to the gatekeeper t o ensure that the
gateway registration is listed with the gatekeeper and does not expire. Enter a value in seconds in the
field.
Step 9 In the Gateway registration mode field, choose the method of registration of services with the
gatekeeper:
• Version 1—For gatekeepers that support H.323 version 1.
• Version 2—For gatekeepers that support H.323 version 2 or later.
Step 10 Select the Unregister from Gatekeeper on ISDN connection failure check box to force the gateway to
unregister from its gatekeeper when both ISDN D-channel connections are no longer active. The
gatekeeper is forced to send new IP-to-ISDN calls through a different gateway, thus ensuring high call
completion rates. The gateway re-registers to the gatekeeper when the ISDN connected is restored.
Step 11 Select the Send load balancing messages (RAI) check box to enable the sending of RAI messages to
the gatekeeper for the purpose of load balancing on the network. If you select this option, perform steps
12 and 13.
Gatekeepers can perform load balancing on the network using feedback from the gateway in the form of
Resource Available Indication (RAI) messages that inform the gatekeeper of gateway resource
availability. If the gateway is unavailable, the gatekeeper performs line hunting operations to route the
call to an alternative gateway.
For the BRI gatekeeper, when you set the gateway for RAI/RAC, it sends periodic RAI messages that
inform the gatekeeper of the current resource availability in the gateway. The gatekeeper responds with
Resource Available Confirmation (RAC) messages to acknowledge receipt of the RAI messages. In steps
12 and 13, you can configure the upper and lower threshold for triggering RAI messages according to
resource availability in the gateway.
Step 12 In the Send ‘busy’ when load is more than field, enter the upper threshold for gateway resource
utilization as a percentage of total resources. When resource use is greater than the threshold, the
gateway sends the gatekeeper a ‘busy’ RAI message, indicating to the gatekeeper that it should stop
routing calls to this gateway.
Step 13 In the Send ‘free’ when load is more than field, enter the lower threshold for gateway resource
utilization as a percentage of total resources. When resource use is less than the threshold, the gateway
sends the gatekeeper a ‘free’ RAI message, indicating to the gatekeeper that it can resume routing calls
to this gateway.

Configuring the Gateway for Peer-to-Peer IP Connectivity
In the IP Connectivity section of the Settings tab, you can configure the gateway for peer-to-peer IP
connectivity.
Procedure
Step 1 In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the Settings tab.
Step 3 Click the IP Connectivity button.
Step 4 In the IP connectivity mode field, choose Peer-to-Peer.
Caution Changing this setting causes the gateway to reset.
Step 5 In the Peer hunting mode field, choose one of the following options:
• Always start from first peer—The gateway attempts to connect a call to the first peer device on
the Peer list section. If the call fails due to one of the H.323 call disconnect reasons (see About
Peer-to-Peer H.323 Call Disconnect Reasons, page 3-8), the gateway tries each peer device in the
Peer list section in order until the call is successfully connected. If the gateway fails to connect the
call after trying all the peer devices on the list, it rejects the call.
• Always start from last successful peer—The gateway attempts to connect a call to the last peer
device in the Peer list section with which a call was successfully established. An arrow in the Peer
list section indicates with which of the peer devices a call was last connected successfully. If the call
fails due to one of the H.323 call disconnect reasons (see About Peer-to-Peer H.323 Call Disconnect
Reasons, page 3-8), the gateway tries each peer device in the Peer list section in order until the call
is successfully connected. The arrow moves to the peer device with which the call connection is
successful. If the gateway fails to connect the call after trying all the peer devices on the list, it
rejects the call and the arrow indicates with which peer device a call was last connected successfully.
This is the default setting.
• Round Robin—As the Always start from last successful peer setting, except that the arrow
advances to the next peer device in the Peer list section even if the call connection succeeds.
Note The peer hunting process starts when any of the following events occur: the gateway fails to
establish a Transmission Control Protocol (TCP) connection to the specified peer device after a
timeout; the gateway receives a “Release Complete” message from a peer device with a “No
Resources” call rejection reason, or one of the other reasons that the Peer-to-Peer disconnect
reason add advanced command specifies; or the gateway establishes a TCP connection to the
specified peer device, but does not receive a valid H.323 message from the peer device after a
timeout.
Step 6 In the Peer list section, you can configure peer devices currently configured to work with the gateway.
The Peer list section displays all configured peer devices in a table with the following columns:
• Peer #—The sequential number of the peer in the list.
• Description—The description of the peer device.
• IP Address—The peer IP address.
• IP Port—The peer IP port number.

Configuring Gateway Settings
• Calls—Displays “Yes” or “No” to indicate whether or not there are currently any active calls
between the peer and gateway.
To change the order of peer devices used in peer hunting, select a peer device and click the up or down
arrow button to change its order.
To add or edit a peer device, click Add or select the peer device and click Edit. Perform the following
steps in the Add peer or Edit peer dialog box:
a. In the IP Address field, enter or edit the peer IP address.
Note Two peers cannot have the same IP address or host name/Uniform Resource Locator (URL).
b. In the IP Port field, enter or edit the peer IP port number.
c. In the Description field, enter or edit the description of the peer.
d. Click Upload.
Note You cannot add a single peer to the Peer list section more than once.
To delete a peer device, select the peer device and click Delete. Deleting a peer does not cause its active
calls to disconnect, but no new calls route to the deleted peer.
Note The peer hunting process stops when one of the peer devices accepts the call or when the call is
rejected with a disconnect reason. When a gateway has scanned the Peer list section and still
cannot connect a call then the following rules apply: if at least one of the peers rejected the call
due to capacity overload, the call rejection reason (towards the call originator) is “No
Resources”; in all other cases, the call rejection reason is “Unreachable Destination.”
Step 7 In the Peer hunting timeout (sec) field, enter the length of time (between 1 and 10 seconds) for which
the gateway waits for a Transmission Control Protocol (TCP) response from each peer device contacted.
The default value is 5 seconds.
Step 8 Select the Accept calls from defined peers only check box if you want the gateway to reject incoming
calls from IP-side entities not defined in the peer list. If unselected, the gateway allows incoming calls
from IP-side entities not defined in the Peer list section.
Step 9 In the Reject calls from peer devices when less than n B channels are free field, enter the lower
capacity threshold for rejecting calls from H.323 peer devices. The default setting is 6.

About Encoding/Decoding Protocols
A number of video conferencing terminal applications require the G.722 and G.722.1 audio compression
codecs to provide high quality voice communications. The G.722 and G.722.1 formats, using a digital
sampling rate of 7 KHz, provide higher quality voice sampling with a greater dynamic range. The
gateway does not transcode G.722 or G.722.1, but supports them transparently. Since the G.722 codec
is of a much higher audio quality than other codes and requires higher bandwidths, the gateway supports
G.722 and G.722.1 at the following call bit rates:
• G.722 is supported in calls at 224, 256, 336, 384, 448, 512 Kbps (all gateways) and 768, 1472, and
1920 Kbps (PRI gateways only).
• G.722.1 is supported in calls at 64, 2B, and 128 Kbps.
Both endpoints in a call must support G.722 and G.722.1 audio codecs.
About Audio Transcoding
The gateway can support audio transcoding through the Audio Transcoder Module (TCM). The TCM is
a PCI mezzanine card (PMC) that implements Digital Signal Processing (DSP). The TCM has a
processing capacity of up to 20 channels for audio transcoding in video calls.
The Gateway TCM can perform audio transcoding between the following types of audio protocols:
• G.711 (ISDN) to G.723.1 (IP)
• G.723.1 (IP) to G.711 (ISDN)
• G.728 (ISDN) to G.711 (IP)
• G.711 (IP) to G.728 (ISDN)
Note When your unit includes both a gateway and an Cisco IPVC 35xx MCU, G.728 transcoding is supported
on the Cisco IPVC 35xx MCU only.
Each audio codec differs in the audio quality, compression, and bit rates that it provides. G.711 provides
toll quality audio at 64 Kbps, G.728 provides near toll quality audio at 16 Kbps, and G.723.1 provides
voice quality audio at 5.3 or 6.4 Kbps.
ISDN endpoints usually support the G.711 and G.728 codecs. Endpoints on IP networks support G.711
and G.723.1 codecs. By performing transcoding between these audio protocols, the gateway can support
communication between endpoints with codecs that are incompatible with each other.
Audio transcoding can also optimize the audio bandwidth usage either on the IP network (G.723.1 < >
G.711) or on the ISDN network (G.728 < > G.711). Transcoding is particularly useful for ISDN codecs,
where bandwidth can be limited to 128 Kbps for a video call. For example, when G.728 < > G.711
transcoding takes place, the audio bandwidth usage is compressed to 16 Kbps. This provides an
additional 40 Kbps of bandwidth to the existing video bit rate on the ISDN network, contributing to
improved video quality.
Note The Cisco IPVC 3500 PRI Gateways automatically perform A-Law G.711-to-µ-Law G.711 translation
between the IP and ISDN sides if needed.
You can configure the gateway to prioritize the transcoding, giving preference to a particular codec that
is applied to calls, thus optimizing the resource allocation utilized by each call.

About T.120 Data Collaboration Support
The gateway provides full end-to-end support for T.120 data collaboration sessions, provided all
terminals support the T.120 standard in their conferencing applications. In video calls with data transfer,
the gateway accepts whatever bandwidth the ISDN connection defines for the data and dynamically
adjusts the outgoing bandwidth used for data by using the MLP, HMLP and VarMLP formats.
If transcoding or T.120 capabilities are required, the gateway has to reserve resources for these. The
gateway can differentiate between those calls that support T.120 and those that do not. When receiving
calls, the gateway can check whether you are reserving resources for transcoding or for T.120
capabilities.
The gateway enables the user to determine the trade-off between the number of non-T.120 calls that the
gateway can support and the number of calls sent with T.120 capabilities. The total number of calls that
the gateway can support is accordingly reduced by this reallocation of resources.
The H.320 standard defines space allocation within a call. The H.320 standard defines the logic for bit
rate allocation among audio, video, and data channels in the context of the overall bit rate of a call. If
you work with T.120, reallocation of bandwidth is always at the expense of available video resources.
The requirements of the H.320 standard govern this reallocation—it is not configured in the gateway.
The gateway simply decides whether or not to send T.120 capabilities. You configure T.120 capabilities
in the Advanced section of the Gateway interface Settings tab.

Configuring ISDN Channel Bonding Settings for Downspeeding
In the Bonding section of the Settings tab, you can configure ISDN channel bonding parameters that
affect downspeeding functionality. Downspeeding is the ability to complete and maintain a call when
ISDN conditions are bad. In downspeeding, call capabilities are automatically renegotiated when a call
fails. Downspeeding contributes to a higher percentage of call completion on the network. The
Cisco IPVC 3500 Series Gateway supports downspeeding at call setup and in mid-call.
With downspeeding, when connection problems occur at call setup, the gateway attempts to connect a
call at a lower bit rate than that requested. Administrators can configure the gateway to attempt to
connect a video call at a specified minimum bit rate, or to attempt to connect the call as a voice call.
In downspeeding, when connection problems occur in mid-call, the gateway attempts to connect a video
call at the specified lower bit rate. When downspeeding is complete and the call is connected at the
specified lower bit rate, the gateway notifies the Internet Protocol (IP) endpoint of the new call rate.
Procedure
Step 1 In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the Settings tab.
Step 3 Click the Bonding button.
Step 4 Select the Enable bonding check box to enable ISDN bonding support.
Step 5 In the Maximum B channels for bonded call field, choose the maximum number of B channels—3, 4,
5, 6, 8, 12, 23, or 30—that you want to allow for a single bonded call. The default setting for BRI
gateways is 8. The default setting for PRI gateways is 30.
When the number of B channels required to process a bonded call exceeds the number specified in this
field, the gateway performs downspeeding as shown in Tab l e 3- 4 .

Configuring Quality of Service Settings
You can configure the Cisco IPVC 3500 Series Gateway to add a Quality of Service (QoS) IP
precedence code in the IP header of outbound packets on the IP network. Routers on the network that
support this method can give precedence to such coded packets and facilitate the transmission of the
packets more efficiently. You can set priority levels on the gateway for voice calls, video calls, or both.
The Type of Service (TOS) field in the IP header contains eight bits and indicates the three abstract
quality of service parameters:
• Delay (D)
• Throughput (T)
• Reliability (R)
You can use the abstract parameters to choose the actual service parameters when transmitting a
datagram through a particular network. The abstract parameters represent the three-way trade off
between low delay, high throughput, and high reliability. Increasing the performance of one of the
parameters can result in reduced performance of the other two. The TOS field in the IP header is shown
in Figure 3-1.
Figure 3-1 TOS Field in the IP Header
The function of each bit of the TOS field is as follows:
• Bits 0-2: Precedence (an independent measure of the importance of the datagram)
• Bit 3: 0=normal delay,1=low delay
• Bit 4: 0=normal throughput, 1=high throughput
• Bit 5: 0=normal reliability, 1=high reliability
• Bit 6-7: reserved for future use
The possible precedence settings are:
• 111=Network Control
• 110=Internetwork Control
• 101=CRITIC/ECP
• 100=Flash Override
• 011=Flash
• 010=Immediate

Configuring Gateway Resources for Calls
Note This section applies only to Cisco IPVC 3500 PRI Gateways.
In the Resources section of the Settings tab, you can reserve gateway resources for T.120 enabled calls
and for audio transcoded video calls. This section also displays the total number of calls that the gateway
supports at specified bandwidths.
The gateway provides full end-to-end T.120 data collaboration sessions, provided that all terminals
support the T.120 standard in their conferencing applications. In video calls with data transfer, the
gateway accepts whatever bandwidth the ISDN connection defines for the data and dynamically adjusts
the outgoing bandwidth used for data by using the MLP, HMLP, and VarMLP formats.
You can also configure the gateway to prioritize the transcoding, giving preference to a particular codec
that is applied to calls, thus optimizing the resource allocation utilized by each call.

Chapter 3 Configuring the Cisco IPVC 3500 Series Gateway
Configuring Gateway Settings
The gateway supports up to 30 video calls on two B channels. If transcoding or T.120 capabilities are
required, the gateway has to reserve resources for these. The gateway can differentiate between those
calls that support T.120 and those that do not. When receiving calls, the gateway can check whether you
are reserving resources for transcoding or for T.120 capabilities.
Procedure
Step 1 In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the Settings tab.
Step 3 Click the Resources button.
Step 4 In the Maximum number of T.120 calls field, enter the number of T.120 enabled calls that you want to
reserve gateway resources for. The maximum number is 18.
Step 5 In the Maximum number of video calls with audio transcoding field, enter the number of audio
transcoded video calls you want to reserve gateway resources for. The maximum number is 20.
Note The term audio transcoded video calls refers to the process whereby an audio stream in a
multimedia call is transcoded from one codec type to another.
Step 6 In the Total call capacity in n calls of n Kbps field, choose a bandwidth.
Step 7 Click Update total call capacity.
The number of calls that the gateway can support at that bandwidth automatically appears.
Configuring Gateway Encryption
The gateway supports encrypted calls over IP networks. The encryption conforms to the H.325 standard
and supports the following encryption algorithms:
• DES—With an encryption key of 56 bits
• AES—With an encryption key of 128 bits
Gateway encryption operates in one of the following modes or can be disabled entirely:
• Best effort—Implements a “best effort” encryption algorithm. If an endpoint supports encryption, it
connects in an encrypted way. If not, it connects without encryption.
• Encryption required—Only connects encrypted calls. Encryption can either be AES 128 or DES 56.
The gateway does not allow non-encrypted calls to connect.
• Strong encryption required—Only allows AES 128 encrypted calls. The gateway does not allow
endpoints that do not support AES 128 to connect.
Note An encrypted call uses double the resources of a regular call for all bandwidth rates. Gateway capacity
when encryption is supported is therefore half of regular gateway capacity, rounded up to the nearest
whole call.
Table 3 -7 summarizes the encryption-related capabilities that the gateway offers.

Auto dial voice call in case of video call fail Select to instruct the gateway to attempt to
reconnect video calls as voice calls after a video
call has failed at call setup. The gateway uses the
auto-redial mechanism for outgoing video calls
when any of the ISDN disconnect reasons listed
below occur.
When selected, the gateway first tries to redial the
call as a restricted video call at 56 Kbps. If the call
fails for any of the reasons listed below, the
gateway tries to redial the call as a voice call.
When unselected, the call disconnects.
The gateway log indicates both the disconnect
reason and the gateway attempt at redialing.
Note The auto-redial mechanism operates
independently of the downspeeding
functionality.
The ISDN disconnect reasons are:
• 0x12—No user responding.
• 0x39—Bearer capacity not authorized.
• 0x3a—Bearer capacity not presently
available.
• 0x3f—Reports a “service or option not
available” event only when no other cause in
the “service or option not available” class
applies.
• 0x4f—Reports a “service or option not
implemented” event only when no other
cause in the “service or option not

• 0x41—Bearer capability not implemented.
• 0x45—Requested facility not implemented.
• 0x58—Incompatible destination.
Use default service bit rate of n kbps for
services defined to use ‘auto’ bit rate
Choose the default bit rate. When using a service
with the bit rate set to Auto, the gateway uses the

The gateway sends the T.120 messages before
connecting to the IP network endpoint.
Support sub-address at Call Setup Sub-addressing is a one-stage Direct Inward
Dialing (DID) dialing mechanism in which a
phone sends two numbers. One number is for
routing on the circuit switched network. The other
number is forwarded to the gateway inside a
Q.931 sub-addressing information element for IP
address resolution by the gatekeeper.
Sub-addressing can also be used for implementing
ISDN fallback when not enough bandwidth is
available for routing an IP-oriented call over IP.
Select for the gateway to take the E.164 number
from the Q.931information element sub-address
field and forward it to the gatekeeper for address
resolution. Sub-addressing requires gatekeeper
support.
IP Options section
Support H.323 Fast Start in voice-only call
setup
The H.323 fast start functionality enables
endpoints that support the feature to join a voice
conference in the gateway more quickly.
Standard call setup requires four round trips of
messages between endpoints before the first
media stream is exchanged between peers. The set
of messages includes Setup/Connect (Q.931
procedure), Master/Slave Determination (H.245
procedure), Capability Exchange (H.245), and
Open Logical Channel (H.245).
H.323 fast start shortens the time it takes to start a
call by skipping the H.245 phase and combining
the call setup procedure into a single H.225
transaction.
Select to encapsulate H.245 capabilities exchange
and negotiation messages within Q.931 setup
messages.

Enable packet handling (may increase call
delay)
Select to configure the maximum rate of jitter
tolerance in the Network jitter tolerance field.
Jitter occurs when IP packets sent at a steady rate
reach their destination at different speeds.
Streams can also split on their way to the gateway
between different routers. This can cause a “later”
packet B to arrive before an “earlier” packet A,
even though A was sent before B.
Network jitter tolerance If you selected the Enable packet handling (may
increase call delay) check box, then enter the
maximum rate of jitter tolerate in milliseconds.
Packet loss occurs when jitter exceeds the
configured rate.
ISDN Options section (For PRI Gateways only)
Request ISDN rollover when less than n B
channels are available
Select to define when the gateway uses the ISDN
rollover feature (Which is defined in advanced
commands. See Configuring Advanced
Commands, page 3-32 for more information).
When the total number of available B channels in
both PRI ports falls below the number specified in
this field, the gateway sends a “busy out” message
to the PSTN switch for each of the remaining B
channels. The switch application “busies out” the
remaining B channels and diverts new calls to
other gateways on the network with greater
available resources. This setting is only active
after you configure the gateway to use a 4ESS PRI
line.
For example, you specify 10 in the Request ISDN
rollover when less than n B channels are
available field and the number of available B
channels falls to 9. The gateway sends a “busy
out” request message to the PSTN switch. The
PSTN switch application routes new calls through
other gateways on the network. When the total
number of available B channels returns to at least
10, the gateway sends a “busy out” cancellation
message to the PSTN switch indicating the
restored ability to receive calls. The PSTN switch
makes the “busied out” lines available and
attempts attempt to route new calls through the
gateway.

About DTMF Settings
The Cisco IPVC 3500 Series Gateway performs Dual Tone Multi-Frequency (DTMF) detection on
IP-to-ISDN calls and on ISDN-to-IP calls. The gateway can send DTMF tone information to the IP
endpoint. in-band only or both in-band and out-of-band. The gateway sends DTMF tone information to
the ISDN endpoint in-band only.
Note For PRI Gateways, enabling DTMF detection for video calls reduces the number of supported calls at
128 Kbps from 30 to 22.
About DTMF
The signal generated by a DTMF encoder is a direct algebraic summation, in real time, of the amplitudes
of time sine (or cosine) waves of different frequencies.
An example of the use of DTMF is in touch tone telephone dialing. DTMF tones are sent out as you dial.
For example, pressing “1” sends a tone created by combining frequencies of 1209 Hz and 697 Hz.
Restrict Gateway use to MCU conferences only Select for the gateway to send and receive calls to
and from a Cisco IPVC 35xx MCU only. This
setting, together with a scheduling server,
reserves resources for scheduled conferences
only.
Support Presentation Restriction Select to enable support for the presentation
restriction feature. This feature responds to an
instruction from the calling endpoint to forward or
to conceal the endpoint identifier.
Support H.239 Select to enable support for dual video channels
using the H.239 protocol. This setting is selected
by default.
When selected, the gateway supports H.239 in
ISDN-to-IP calls and in IP-to-ISDN calls. the
gateway identifies the protocol version that an IP
endpoint uses and sends H.239 capabilities only
to those endpoints working with protocol version
4.0 or later. H.239 support has no impact on
gateway capacity.
We recommend that you do not enable this feature
if you establish communication with endpoints
that do not support H.245 generic capabilities
(endpoints based on H.323 version 2 or earlier) as
this might cause the endpoints to fail upon
receiving these capability exchanges.

The touch tone system uses pairs of tones to represent the various keys on the telephone. A “low tone”
and a “high tone” are associated with each button (0-9, *, and #). The low tones vary according to the
horizontal row in which the tone button is located in Tab le 3 -9. The high tones correspond to the vertical
column in which the tone is located. The local telephone company receives each pair of tones, decodes
the number dialed and makes the connection.
About DTMF Detection on IP-to-ISDN Calls
The gateway passes incoming in-band DTMF signals to the ISDN-side endpoint unchanged. In addition,
you can configure the gateway to convert H.245 out-of-band DTMF signals from the IP side to in-band
signals on the ISDN side. Figure 3-2 illustrates IP-to-ISDN DTMF processing.

About Gateway Services
Cisco IPVC 3500 Series Gateway services are the mechanism that allows IP network endpoints to
choose the type of connection they want to establish with a terminal or telephone on a circuit-switched
network. A gateway service defines the maximum bit rate for each channel, the media content of the
stream (voice or data), and the mode of the call (restricted or non-restricted).
A service prefix identifies a service. The service prefix is an identifier string that can have up to 31
characters. Valid characters are 0 to 9, pound (#), asterisk (*), or comma (,). You access a service by
dialing the service prefix before the phone number of the destination. For example, 9* would be
identified by the gateway as a service prefix if you dialed 9*5673994.
Note If the Ignore caller bearer rate and force service rate setting in the Advanced section of the Settings
tab is selected, a service uses the defined bit rate. If the Ignore caller bearer rate and force service
rate setting is unselected, the bit rate defined in the service serves as the maximum limit for the service.
The gateway has two types of services: default and user-defined. Default services come pre-configured
on the gateway. User-defined services are services that you can define at any time using the Gateway
interface. Upon registration with a gatekeeper, the gateway provides the gatekeeper with a list of gateway
services.
The following topics discuss how you can configure services in the Services tab:
• Viewing Existing Services, page 3-34
• Adding or Editing Services, page 3-35
• Deleting Gateway Services, page 3-36
Viewing Existing Services
The Services tab in the Gateway interface displays a list of currently defined services for the gateway in
a table format with the following columns and fields:

Adding or Editing Services
In the Services tab, you can add a new service or edit an existing one.
Procedure
Step 1 In the Gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the Services tab.
Step 3 To add a new service, click Add. To edit an existing service, select it and then click Edit.
Step 4 In the Prefix field, enter or edit the prefix number of the service. The prefix can be up to 31 characters
long. Valid characters are 0 to 9 and pound sign (#), asterisk (*), and comma (,).
Note Since the comma cannot be used in the Party number field of the Cisco IPVC 35xx MCU
Conference Control interface, we recommend that you do not use the comma as a prefix in
gateway fields.
Step 5 In the Description field, enter or edit the description of the service (up to 31 characters in length).
Step 6 In the Call type field, select the call type for this service: Video or Voi ce .
Step 7 In the Bit rate field, select the maximum bit rate you want for this service. If you select Auto, the
gateway determines the ISDN call rate according to the bearer capability received in the setup message
from the IP network endpoint.
Note The Auto setting is for video calls only.
If the IP network endpoint has a configured bit rate that is not one of the options listed in this field, the
gateway uses the default bit rate configured in the Default Service Bit Rate field in the Advanced
section of the Settings tab.
Note If the Ignore caller bearer rate and force service rate field is selected when you define a bit
rate for a service, the service uses the defined bit rate. If the Ignore caller bearer rate and force
service rate is unselected, the bit rate you define serves as the maximum limit for that service.

Step 15 Select the Enable Alerting check box for the gateway to connect a voice call that is not rejected (instead
of sending alert messages to the caller).
The alerting feature is relevant for incoming voice calls routed directly to an endpoint (through DID) or
to a default extension. When you select this option, the gateway sends an alert message to the dialing
ISDN terminal if the call is not connected within a few seconds. This informs the ISDN terminal that the
call is not yet connected to the local IP endpoint. As a result, the ISDN terminal continues to hear a
ringing sound until the gateway connects to the call.
Note The gateway connects the call even if the endpoint on the local IP network has not yet accepted
it. If the IP endpoint does not accept the call, the call is rejected and immediately disconnects
from the ISDN terminal.
This setting is selected by default. Unselect it to prevent the gateway from sending an alert message.
Step 16 Select the Enable Layer 1 Line Hunting check box if you do not want the gateway to hunt BRI lines
whose Layer 1 is not activated. This setting is unselected by default.
