Release Notes for Cisco uBR7200 Series for Cisco IOS Release 12.1 T
78-10643-04 Rev. B0
New and Changed Information
New Hardware Features in Release 12.1(1a)T1
The following new hardware features are supported by the Cisco uBR7200 Series Universal Broadband
Routers in Cisco IOS Release 12.1(1a)T1.
Broadband Wireless—Point-to-Point
The Cisco high-speed point-to-point broadband fixed wireless system provides a fixed, dedicated
wireless link from one site to another. This link delivers full-duplex data in the Unlicensed National
Information Infrastructure (U-NII) band (5.725 to 5.825 GHz).
The broadband fixed wireless system consists of a Cisco uBR7200 Series Universal Broadband Router
(Cisco uBR7246 or Cisco uBR7223) and one or more point-to-point wireless modem cards, each with
a power feed panel and one or two wireless transverters.
The point-to-point wireless modem cards are installed in a Cisco uBR7200 series router. Each modem
card is cabled to a power feed panel installed either in the same equipment rack as the router or mounted
on a wall. Cables from the power feed panel are attached to one or two wireless transverters, which are
installed on antenna masts. The system is managed using a command-line interface (CLI) or CiscoView.
The Cisco IOS software has a number of new and enhanced commands to support the point-to-point
wireless modem card. The point-to-point wireless modem card is also one component of a complete
fixed wireless subsystem. For more information about the new commands and additional wireless
hardware, see the Cisco uBR7200 Series Wireless Modem Card and Subsystem Installation and
Configuration publication.
Note Not all port adapters are supported with the point-to-point wireless modem card. The
HSSI, 10BaseT Ethernet, 100BaseT Ethernet, and serial Frame Relay interfaces are fully
supported. The ATM, POS, and Gigabit Ethernet port adapters were not supported with
the point-to-point wireless modem card at the time Release 12.1(1a)T1 was released.
Cable Modem Card (MC16E)
The MC16E Cable Modem Card provides one downstream and six upstream connections to the cable
network, similar to the MC16C Cable Modem Card, except that it supports the ITU J.83 Annex A
physical layer and the proposed EuroDOCSIS (Annex A) standard (Cable Labs ECR RFI-R-98036).
The MC16E card has the following differences with the current MC16C card:
• Downstream 36.125 MHz interface, with an 8-MHz DAVIC/DVB channel width and interleave
factor of I=12, J=17
• Downstream symbol rate of 6.592 Msymbols/sec at 64 and 256 QAM
• Downstream channel range of 85 to 860 MHz
• Upstream channel range from 5 to 65 MHz
• Supported in the Cisco uBR7200 series MIBs
• Supports EuroDOCSIS-compliant cable modems and set top boxes (STBs)
All cable interface commands have been updated to support the MC16E Cable Modem Card.
