H80DVCPE Board Description

H80DVCPE Board Description

H80DVCPE is a 64-port VDSL2 over POTS Service Board with built-in splitter. Using its VDSL2 port, the H80DVCPE board works with the VDSL transceiver unit, remote terminal end (VTU-R) to provide 64 channels of VDSL2 access services. In addition, it supports vectoring.

Feature and Specifications

Please refer to "64-Channel VDSL2 Service Board Comparison".

Technical Specifications

Please refer to "Power Consumption and Maximum Frame Size of Boards".

Working Principle

Figure 3-134  Working principle of the H80DVCPE board

The basic working principle of the H80DVCPE board is as follows:
  • The control module loads the board software, controls the running of the board, and manages the board.
  • The protection module protects and isolates the board from lightning strikes. The DC block isolates the direct current. The protector protects the high voltage.
  • The splitter module separates POTS signals from VDSL2 signals over the subscriber line.
  • The interface module provides two functions:
    • In the upstream direction, the interface module converts line signals into cell flows, aggregates the cell flows to the forwarding module, and then reassembles the cell flows into ATM/PTM packets.
    • In the downstream direction, the interface module converts the ATM/PTM cell flows sent from the forwarding module into line signals that are transmitted downstream.
  • The forwarding module processes services. For details, see the description of service processing.
  • The power module supplies power to other functional modules of the board.
  • The clock module provides the working clock for other functional modules of the board.
The service processing is as follows:
  • In the upstream direction, the splitter module separates LINE signals over the subscriber line into POTS signals and VDSL2 signals, and then the interface module transmits these signals to the forwarding module. The forwarding module reassembles the cell flow into ATM/PTM packets, encapsulates the ATM/PTM packets into IP packets, and performs CAR on the IP packets. Controlled by the logic switch, the IP packets are transmitted to the backplane bus through the backplane interface.
  • In the downstream direction, the forwarding module decapsulates the IP packets sent from the backplane bus, perform CAR on the packets, reassembles the packets into ATM/PTM packets, and then transmits the ATM/PTM packets to the interface module. The interface module then converts the ATM/PTM packets into analog signals, and transmits the analog signals to the subscriber line through the splitter module.

Front Panel Port



  • When cables from the PSTN and LINE ports are routed to an outdoor environment, the MDF must be installed with a protective unit.
  • When cables from the LINE port are routed to the user side, the MDF must be installed with a protective unit.
  • The PSTN port must be connected to an MDF with a protective unit or a POTS device. Otherwise, when the LINE port is struck by lightning, energy inside the SPL board or unit fluctuates and overlaps, which may damage the LINE port.

Pin Assignments

The pin assignments of LINE ports are the same as those of the PSTN ports. Table 3-142 describes the pin assignments of the PSTN0 port, and Table 3-143 describes the pin assignments of the PSTN1 port.
