Note: 1. A DVA is considered an MTA for the choice of provisioning servers and for filtering.
2. Sometimes called DOCSIS Set-top Gateway, or DSG.
The most common device classes used by customers are MTA and STB. If a CPE device does not perform one of the specific
specialized functions acknowledged by the device class feature, then it is considered a generic CPE device.
Note: This feature does not support IPv6 CPE device classes. Such CPE devices are treated as generic CPE devices. For CPE
devices using a dual mode IPv4/IPv6 stack, the C4/c CMTS will recognize only the device class that can be determined from
the IPv4 Dynamic Host Configuration Protocol (DHCP) Relay Agent.
Functionality
Through the classification of CPE devices, the user is allowed to:
Associate different provisioning servers for CPE devices based on the class of the device.
Apply a given secondary cable interface to be available to provide policy support for CPE devices based on the class of
the device.
Apply different filtering of traffic from CPE devices based on the class of the device.
Identify an individual CPE device class type behind a given CM using the show cable modem detail command.
IPv6 VoIP Support
Beginning in Release 8.2.5, the C4 CMTS supports the IPv6 address family for IP addressing to DOCSIS 3.0 MTAs or DOCSIS
3.0 embedded Digital Voice Adapters (eDVAs).
