InCoax DPU – Hardware User Manual
11
Once the DPU has been installed in, or near, the building the only required operation to connect new
customers is to provide them with a Modem.
(Please refer to the InCoax handbook System Design Guidelines for Cable Technicians for guidance).
As soon as the Modem has been connected to the coaxial network, it will automatically be detected and
configured by the DPU through the Management System (if such setup has been enabled in the Management
System).
The typical MoCA Access DPU System consists of distributed Management System Architecture which handles
thousands of DPUs and millions of Modems. If there is a legacy cable-TV service in the building the TV signal
must be combined with the broadband signal using the Diplexer Filter. The Management System is used as a
customer configuration, monitoring, and provisioning tool through a web interface or be accessed by
provisioning system or Operating Support System through NETCONF or TR-069 interface.

3.2 The DPU
The DPU acts as a bridge between the incoming XGS-PON, GPON, EPON or Ethernet access network and
customers’ Ethernet Modem port, using the in-building coaxial network as transport for data traffic to the
Modems . The DPU communicates with all Modems , over dedicated RF bands, in the coaxial network to manage
their individual configuration, enforces traffic, and security policies. It also collects and stores traffic statistics
data from the network.
3.2.1 D2508 Input Power alternatives
The DPU is powered by the AC Power cord connected to the public power grid (100 – 120VAC or 200 –
240VAC). It can also be powered through the coax cable by Reverse Power Feeding (RPF) from a customer
modem. To offer this powering, an InCoax Reverse Powering modem must be used. If Reverse Power Feeding is
to be utilized, only one modem per RF port can be connected. DPU with RPF capabilities is named D2508 RPF or
D2508 RPF ER.
When powered by RPF, the AC power cord can then be detached from the AC outlet. To ensure continuous
power, the AC power cord can still be connected to AC power. AC power will be prioritized when present.
