Platform Support for Cisco Cable Modem HWICs
The Cisco Data-Over-Cable Service Interface Specification (DOCSIS) cable modem HWICs are
supported in the following Cisco routers: Cisco IAD2431 Integrated Access Devices; Cisco 3725, and
Cisco 3745 routers; and Cisco 1800 (modular), Cisco 2800, and Cisco 3800 Integrated Services Routers
(ISRs).
Note The Cisco 815 ISR for Broadband Cable does not support WIC or HWIC modules, however, the
underlying cable modem technology is identical to that of the cable modem HWIC.
Table 45 shows the Cisco router platforms that support the Cisco cable modem HWICs.
Note For specific information about WIC/HWIC support for the routers that support the Cisco cable modem
HWICs, see the hardware installation documentation for your router at www.cisco.com.

Note The performance of the 815
matches the performance of
the WIC mode. The cable
modem in the 815 is a fixed
configuration and is not field
replaceable.
1. When the cable modem HWIC is placed in these routers, the HWIC operates only in WAN
interface card (WIC) mode, providing total throughput on the cable modem HWIC of 16 MB
(8 MB upstream and 8 MB downstream).
