System Requirements • The multimode four-pair G.SHDSL EHWICs are supported
on all modular Cisco ISR G2 routers: Cisco, 1921, 1941, 2901, 2911, 2921, 2951,
3925, 3945, 3925e, and 3945e. • The multimode four-pair G.SHDSL EHWICs are
supported in all Cisco IOS® Software feature sets. • The routers listed
previously need to run Cisco IOS Software Release 15.2(2)T or later. • The
system requires no additional flash or DRAM memory other than the specified
minimum memory for the previously mentioned Cisco IOS Software releases. • The
multimode four-pair G.SHDSL EHWICs can be inserted into any EHWIC slot in any
ISR G2 router.
