78-10643-04 Rev. B0

System Requirements

• MC16S spectrum management cable modem cards offer the following ports:

–

six upstream ports, with dedicated hardware support for enhanced hardware-based spectrum

management

one downstream port

Table 4 provides a quick overview of the cable modem cards that are supported in Cisco IOS

Release 12.1(5)T.

Port Adapter Cards

Table 5 lists and describes the port adapters supported by Cisco uBR7200 series routers in Cisco IOS

Release 12.1(5)T.

Note Not all Cisco uBR7200 series routers support all port adapters. Some port adapters must

be at certain revision levels to be used in the Cisco uBR7246 VXR router.

Note Not all port adapters are supported with the point-to-point wireless modem card. The

HSSI, 10BaseT Ethernet, 100BaseT Ethernet, serial Frame Relay, ATM, and POS

interfaces are fully supported. The Gigabit Ethernet port adapter was not supported with

the point-to-point wireless modem card at the time the Cisco IOS Release 12.1(5)T

software was released.

Tips The Cisco IOS Releases shown in Table 5 are the minimum releases in the 12.1 EC train that support

each port adapter. However, Cisco recommends using the most current release of a train if possible.
