H80BADPE Board Description

H80BADPE Board Description

The H80BADPE board is an 64-port ADSL2+ over POTS service board. It works with the ADSL terminal unit-remote end (ATU-R) through the ADSL2+ port to access 64 channels of ADSL2+ service.

Functional Specifications

Please refer to "64-Channel ADSL2+ Service Board Comparison".

Technical Specifications

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

Working Principle

Figure 3-109  Working principle of the H80BADPE board

The basic working principle of the H80BADPE board is as follows:
  • The control module loads the board software, controls the running of the board, and manages the entire 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 ADSL2+ signals over the subscriber line.
  • The interface module supports two functions:
    • In the upstream direction, the interface module converts line signals into a cell flow, aggregates the flow to the forwarding module, and then reorganizes the flow into ATM packets.
    • In the downstream direction, the forwarding module transmits the ATM cell flow to the interface module. Then, the interface module converts the flow into downstream line signals.
  • The forwarding module processes services. The detailed process is described later.
  • The power module supplies power to each functional module of the board.
  • The clock module provides clock signals for each functional module of the board.
The service process is as follows:
  • In the upstream direction, the splitter module separates POTS signals from ADSL2+ signals over the subscriber cable, and then the interface module transmits such signals to the forwarding module. The forwarding module reorganizes the cell flow into ATM packets, encapsulates the ATM packets into IP packets, and then performs CAR on the IP packets. Controlled by the logical 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 from the backplane bus, performs CAR on the IP packets, reorganizes the IP packets into ATM packets, and then transmits the ATM packets to the interface module. The interface module converts the ATM packets into analog signals and transmits the 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 assignment of the LINE port and that of the PSTN port on the H80BADPE board are the same. For pin assignment of the PSTN0 port, see Table 3-92; for pin assignment of the PSTN1 port, see Table 3-93.
