Cisco Cisco IOS Software Release 12.2(2)XK

The following sections list the new features supported by the Cisco ICS 7750 series for Cisco IOS 
software releases Release 12.2(2)XK2.

Cisco IOS Release12.2(2)XK2 on the Cisco ICS 7750 supports the following new hardware features:

The Cisco ICS 7750 now supports two-port Foreign Exchange Office (FXO) voice interface cards for 
the United States using the battery reversal VIC-2FXO-M1 card. The Cisco FXO interface is an RJ-11 
connector that allows an analog connection to be directed at the PSTN central office or to a station 
interface on a PBX. The FXO is on the switch end of the connection and plugs directly into the line side 
of the switch, so the switch perceives the FXO interface as a telephone. FXO-M1 is an enhancement of 
FXO with battery reversal and Caller ID features.
