Implementing and Configuring the Solution
Configuring the Wideband SIP and Wideband SPA
The wideband CMTS components that require configuration include the Cisco Wideband SIP and Cisco
Wideband SPA. Cisco IOS commands are issued on the uBR10012 router to configure the Wideband SIP
and SPA. An outline of the configuration tasks needed for the Wideband SIP and SPA is as follows:
•
•
•
•
•
•
For information on the preceding tasks and for reference information on the Cisco IOS commands used
for Wideband SIP and SPA configuration, see the Cisco uBR10012 Universal Broadband Router SIP and
SPA Software Configuration Guide.
Configuring the Edge QAM Device Configuration
Edge QAM (EQAM) device configuration is device-specific and implementation-specific.
•
•
Regardless of the edge QAM device or implementation, these items are used for Wideband SPA
configuration and must be configured on each EQAM device:
•
•
The IP address, MAC address, frequency, and UDP port configured on the edge QAM device are
specified when configuring RF channels on the CMTS. Be certain to verify that the RF-channel values
set with rf-channel (issued on the CMTS) match the values configured on the edge QAM device.
If a Layer-2 Gigabit Ethernet switch is used to connect the Wideband SPA to the EQAM device, the MAC
Note
address specified in the rf-channel command is the MAC address of the switch's Gigabit Ethernet
interface.
An RF channel and EQAM configuration worksheet such as the one shown in
for coordinating Wideband SPA RF channel and EQAM device configuration. A Wideband SPA supports
either 18 or 24 RF channels depending on how the SPA is configured. For more information, see the
description of the rf-channel command in the Cisco uBR10012 Universal Broadband Router SIP and
SPA Software Configuration Guide.

For the Scientific Atlanta Continuum DVP XDQA24 device, the Continuum DVP eXtra Dense QAM
Array 24 Configuration Guide contains configuration information. See the appendix "Cisco
Wideband Applications" in that document for information on configuring this EQAM device for
wideband.
For information on configuring other EQAM devices, refer to the device's documentation.
For the edge QAM device:
IP address of the EQAM device's Gigabit Ethernet interface (input port)
–
MAC address of the EQAM device's Gigabit Ethernet interface (input port)
–
For each of the EQAM device's QAM outputs that will be used for a Wideband SPA RF channel:
Center frequency of the QAM output
–
UDP number of the QAM output
