Prepare for Installation (continued)
Verify the Following Before Going to a Subscriber Site:
Item Description
General
Coaxial cable is run from the CATV trunk to the subscriber building or residence.
Note: Cisco recommends that a dedicated (new) CATV cable drop be run from the grounding block
directly to the Cisco uBR924 cable access router. If such a drop is not available, careful qualification of
existing cable is often necessary. Cable ground should be connected to the grounding system of the
building or residence as close to the point of cable entry as practical. For the United States, refer to NEC
section 820-40 guidelines for proper grounding.
The site is characterized from the headend to support upstream transmission and meets DOCSIS upstream
and downstream RF requirements. Follow procedures in the NCTA Recommended Practises for
Measurements on Cable Television Systems.
All required headend routing and network interface equipment is installed, configured, and operational.
This includes all routers, servers (DHCP, TFTP, and TOD), network management systems, and/or other
configuration or billing systems.
DHCP, Cisco IOS images, and DOCSIS configuration files have been created and pushed to appropriate
servers such that each Cisco uBR924 cable access router, when initialized, can transmit a DHCP request,
receive an IP address, obtain TFTP and TOD server addresses, and download a DOCSIS configuration file
(and/or updated software image) in compliance with DOCSIS.
Note: The router’s cable MAC address found on a label at the bottom of the unit ensures each unit
downloads only the file(s) intended for that router.
PCs at each subscriber site meet the minimum computing requirements and that TCP/IP and DHCP
operating modes are enabled. Cisco recommends that the PC have a 486 DX 33 MHz processor minimum
configuration (a 75 MHz Pentium or greater processor is recommended); 16 MB of RAM; Windows for
Workgroups for 486-based PCs and Windows 95 (or higher) for Pentiums; an Internet browser; and a
pre-installed Ethernet Network Interface Card (NIC) with DHCP enabled.
Note: This recommendation is for Internet access in general. Other operating systems and hardware
platforms of comparable capability are also supported.
IP
Telephony
Telephones at each subscriber site support touch-tone dialing; rotary dialing is not supported.Wiring is in
place at subscriber sites supporting multiple telephones and fax devices per VoIP telephone line.
Fax devices—standard Group III and computer-based Group III machines up to 14,400 baud—are
supported in Cisco IOS Release 12.0(5)T or higher.
Note: In general, fax/modem cards are not supported over Voice over IP (VoIP) links. Contact your
network management, provisioning, or operations team to determine what your network supports.
A regular voice grade line and RJ-11 modular jack (USOC code) is installed near the location to install the
router for all sites that support backup PSTN connections.

3
Install the Router and Connect Cables
The Cisco uBR924 cable access router is DOCSIS-based and interoperates with any DOCSIS-qualified CMTS.
TherouterusesCiscoIOSRelease 12.0(4)XI,12.0(5)T,or highersoftware,andsupports manyadvancedrouting
features. The router can be configured to support data, voice, or a mixture of data and voice.
Note: The router ships from the Cisco factory with the console port enabled and a software image that
supports data only. Based on your licensing agreement, you can use Cisco Connection Online (CCO) to
download an image or images that support voice and/or other operating modes. Downloading a Cisco IOS
image disables the console port by default and erases all saved configurations.
Safety Information
Note: Before installing equipment, review the Regulatory Compliance and Safety Information for the
Cisco uBR924 Cable Access Router publication and follow all guidelines. Also refer to the Cisco uBR924
Cable Access Router Installation and Configuration Guide for more in-depth instructions.
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Install the Router
Step 1 Place the router on a stable, flat surface close to the CATV drop connection and all devices to be
connected at the subscriber site.
Step 2 Make sure the bottom, sides, and rear of the router are clear and well-ventilated to prevent the unit
from overheating.

to a backup POTS line.
Note: If the Cisco uBR924 cable access router has
a backup connection to the PSTN and the router
loses power while VoIP calls are in progress, the
subscriber can re-establish one of the two VoIP line
connections—dialing out over the PSTN.
Caution The backup POTS connection
enables only one of the two voice lines
connected to the router to function during a
power outage. Calls in progress prior to the
power outage will be disconnected.
If power is re-established while a cutover
call is in progress, the connection will
remain in place until the call is terminated.
When the cutover call is terminated, the
router automatically reboots.
Warning This equipment is to be installed
andmaintainedbypersonnelonlyas defined

Initialize the Router
View Initialization
When the router is connected and powered on, it executes automatic self-diagnostic and installation procedures.
For this to occur, a number of actions must be performed at the headend. Refer to the “Prepare for Installation”
section of this guide. The initialization process follows:
• All LEDs on the front of the router light (except for the ACT LED and LEDs 1 through 4) when the router
first powers on.
• Different LEDs light to indicate diagnostic progress and turn off after all checks are successful.
• The OK LED then blinks as the router completes self-test and boots a Cisco IOS image.
• The router, in accordance with DOCSIS, acquires a downstream channel, establishes communications with
the headend, and downloads a configuration file (and an optional updated image if set).
• When the download is complete, the following LEDs light and remain solid to indicate the router is
operational:
—DS LED reveals the router is locked to a downstream channel.
—US LED reveals the upstream channel is operational.
—LINK LED reveals the cable interface is operational.
—DSNR LED reveals the router is receiving a good downstream signal-to-noise ratio.

Verify Installation
Verify Connections
Internet
Step 1 From a PC connected to the router, start the Internet browser program installed on the PC.
Step 2 In the appropriate area of the web browser screen, enter a URL of your choice.
Note: If a URL is not known, try using http://www.cisco.com.
If the selected web page displays, the Ethernet network installation is successful.
Step 3 Watch the appropriate Ethernet LED (1 through 4) on the front of the router blink as data is
transmitted on the link.
Step 4 Repeat steps 1 through 3 for each PC connected to the router.
VoIP Telephone
Step 1 Pick up a telephone connected to one of the router’s VoIP (V1+V2 or V2) rear ports.
Note: The router must be configured to support voice.
Step 2 Dial a telephone number.
The Cisco uBR924 cable access router is able to implement multiple classes of service (CoS) on the
cable interface.
Note: Separate CoS streams are only available when the router is connected to a headend that supports
multiple classes of service per Cisco uBR924 cable access router. In addition, the configuration file downloaded
to the router must specify use of multiple classes of service.
Caution The Cisco uBR924 cable access router interoperates with a DOCSIS 1.0 CMTS that does not
support multiple classes of service per router. Because voice and data will be mixed, however, voice
traffic will be transmitted on a best effort basis. This can cause poorer voice quality and lower data
throughput when calls are made from the router’s telephone ports.
Voice qualityis also affected by users transmitting or downloading largefiles, as well asother significant
network traffic.

12
Verify Installation (continued)
Step 3 Watch the appropriate VoIP LED (V1 or V2) on the front of the router light when data is transmitted
on the link.
Any call-progress indications and other signals that can be carried inband (for example, remote
telephone ringing) are cut through the voice path as soon as an end-to-end audio channel is up. As
applicable, class reservations are put in place to achieve the desired CoS over the cable interface.
Step 4 Ensure the call is picked up before hanging up.
VoIP Fax
Step 1 Place a document in the document feeder of a fax machine connected to the router, referencing
instructions appropriate to the fax device.
Note: The router must be configured to support voice and you must be using Cisco IOS Release 12.0(5)T or
higher.
Step 2 Enter a destination number to receive the fax and press Dial or Start on most fax machines.
The protocol appropriate to fax is turned on and the fax proceeds. Any call-progress indications and
other signals that can be carried inband (for example, remote telephone ringing) are cut through the
voice path as soon as an end-to-end audio channel is up.
Step 3 Watch the appropriate VoIP LED (V1 or V2) on the front of the router light as data is transmitted on
the link.
Step 4 Listen for a fax tone on the other end and verify that the fax is transmitted.
Step 5 Verify completion of the fax transmission at the destination.

16
Reconfigure the Router
Note: Cisco uBR924 cable access routers are typically configured at the headend. Most subscriber sites do not
permit local configuration. Remote configuration is either disabled or routinely reset to settings in the
provisioning or billing systems.
Caution Before attempting to reconfigure a Cisco uBR924 cable access router at a subscriber site,
contact your network management, provisioning, or billing system administrator to ensure remote
configuration is allowed. If remote configuration is disabled, settings you make and save at the local site
will not remain in effect after the router is powered off and on. Instead, settings will return to the
previous configuration.
Connect the Console Port
Step 1 Configure the terminal to support:
• 9600 baud
• 8 data bits
• No parity
• 1 stop bit (8N1)
Step 2 Connect the terminal to the Cisco uBR924 cable access router’s console port.
Note: The console port is configured as DCE and uses an RJ-45 connector. The port is wired the same as all
other Cisco products.
Caution After you connect a laptop to a Cisco uBR924, perform all actions, and save configuration
changes, power cycle the router if that laptop will not be used at the subscriber site. This is particularly
important when the Cisco uBR924 is configured to operate in a DOCSIS-compliant bridging mode.
Power cycling the Cisco uBR924 ensures the laptop computer does not remain in the list of CPE devices
at the subscriber site for the Cisco uBR924 to support. Only reinitialization of the cable interface clears
out the bridge table and resets the counter that specifies the number of CPE devices being bridged. Refer
to the “Basic Internet Access Bridging Example” section of this document.
Note: This behavior is in accordance with DOCSIS. For configurations including Cisco Series 7200 CMTS
equipment, issuing the clear cable modem host <mac address> command may be required to clear the laptop
from the headend security access control tables.
