Early Deployment Releases
Cisco CVA122 Cable Voice Adapter
The Cisco CVA122 Cable Voice Adapter features one F-connector interface to the cable system, one 
RJ-45 (10BASE-T Ethernet) hub port, one USB device port, and two RJ-11 analog voice ports. The USB 
interface enables the cable voice adapter to connect to a PC with a USB interface, without having the 
user to open the unit and install an Ethernet network interface card (NIC). If supported by the PC and 
service provider, PCs can be connected to the cable voice adapter using both the Ethernet and USB 
interfaces. 
The Cisco CVA122 Cable Voice Adapter supports the DOCSIS standard, which was developed with 
service providers to ensure that any DOCSIS-certified cable modem can interoperate with any 
bidirectional, DOCSIS-qualified CMTS. The DOCSIS standard supports the North American National 
Television Systems Committee (NTSC) channel plan, with 6 MHz channel widths, a downstream range 
of 88 to 860MHz, and an upstream range of 5 to 42 MHz. 
The feature sets available in Release 12.2(2)XA4 for the Cisco CVA122 Cable Voice Adapter include 
the DOCSIS IP Bridging, IP Routing, and the Easy IP feature sets. 
Cisco CVA122E Cable Voice Adapter
The Cisco CVA122E Cable Voice Adapter features one F-connector interface to the cable system, one 
RJ-45 (10BASE-T Ethernet) hub port, one USB device port, and two RJ-11 analog voice ports. The USB 
interface enables the cable voice adapter to connect to a PC with a USB interface, without having the 
user to open the unit and install an Ethernet network interface card (NIC). If supported by the PC and 
service provider, PCs can be connected to the cable voice adapter using both the Ethernet and USB 
interfaces. 
The Cisco CVA122E Cable Voice Adapter supports the EuroDOCSIS standard, which is almost identical 
to the DOCSIS standard, except that it supports the European Phase Alternating Line (PAL) and Systeme 
Electronique Couleur Avec Memoire (SECAM) channel plans, with 8 MHz channel widths, a 
downstream range of 88 to 860MHz, and an upstream range of 5 to 65 MHz. 
The feature sets available in Release 12.2(2)XA4 for the Cisco CVA122E Cable Voice Adapter include 
the DOCSIS IP Bridging, IP Routing, and the Easy IP feature sets.
