The DPC DOCSIS PON Controller allows an operator to roll out an EPON architecture using Alloptic equipment while maintaining current DOCSIS provisioning processes and back office software. The DPC is a proxy that resides between the Alloptic OLT and back office systems, acting as a translator between the two. DPC receives DOCSIS configuration files from the configuration server, and translates that data into provisioning information for the Alloptic OLT and ONTs. From an OSS perspective, the flow-through provisioning of the EPON system takes place in the same way CMTS/cable modems are provisioned.

For cable operators, the problem with PON is that it is not DOCSIS-managed. Back office systems – OSS and BSS – have developed over a long period to provide flow-through provisioning and control of the DOCSIS network.Those highly-evolved back office systems are keys to keeping operational costs low and have allowed MSOs to scale to serve millions of subscribers. When EPON systems are deployed without DPC, provisioning and management must be done manually – outside the automation of DOCSIS systems.That makes PON systems difficult to scale across large networks and expensive for OAM&P functions.
The DPC PON controller from Alloptic solves the problem by enabling DOCSIS management of Alloptic’s EPON system. It is a proxy that resides between the Alloptic OLT and back office systems, acting as a translator between the two. DPC receives DOCSIS configuration files from the configuration server, and translates that data into provisioning information for the Alloptic OLT. From an OSS perspective, the flow-through provisioning of the EPON system takes place in the same way CMTS/cable modems are provisioned. As shown in Diagram 2, the Alloptic OLT takes the place of the CMTS in the access network, and the ONT replaces the traditional cable modem.
With DPC software from Alloptic, network operators can continue to use existing DOCSIS operational support systems while gaining the performance advantages of Alloptic’s EPON system. Beyond simply supporting single port devices such as cable modems, Alloptic’s DPC solution offers flow-through provisioning for the full Alloptic ONT portfolio with multi-port ONTs, multiple voice ports, and native T1/E1 ports. |
