4.1
 Every CM, regardless of
manufacturer or cable
operator, is provisioned
according to DOCSIS
specifications
 Cable operators want to
use the same Operations
and Support Systems
(OSS) with other access
network technologies (i.e.,
EPON)

 Brings the mature systems and business processes of
the DOCSIS OSS to EPON access networks
 Enables full vendor/equipment interoperability – similar
to CMTS and Cable Modems
 Leverages existing technical and customer care
knowledge base, systems, and processes
 Developed by MSOs, CableLabs, and vendors
