H80BCVME Board Description

H80BCVME Board Description

H80BCVME is a 48-port VDSL2&POTS combo board with built-in splitter, providing 48 channels of VDSL2 and POTS access services.

Functional Specifications

Please refer to "VDSL2&POTS Combo Board Comparison".

Technical Specifications

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

Working Principle

Figure 3-83  Working principle of the H80BCVME board

NOTE:
  • GMII is a gigabit media independent interface.
  • S3MII is a source synchronous serial media independent interface.
The basic working principle of the H80BCVME 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 splitter module separates POTS signals from VDSL2 signals over the subscriber line.
  • The broadband interface module converts the VDSL2 line signals into cell flows.
  • The broadband service processing module implements functions such as encoding/decoding, analog-to-digital conversion, and line drive for VDSL2 services. It then sends VDSL2 services to the forwarding module through the GMII interface.
  • The narrowband interface module provides access to 48-channel narrowband service.
  • The narrowband service processing module encodes and decodes narrowband voice services and converts analog signals into digital signals. It then sends narrowband voice services to the forwarding module through the S3MII interface.
  • The forwarding module converts broadband signals and narrowband signals into 10GE/GE signals for upstream transmission through the backplane.
  • 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 signals over the subscriber line into POTS signals and VDSL2 signals. The broadband interface module then sends VDSL2 signals to the broadband service processing module, and the narrowband interface module sends POTS signals to the narrowband service processing module. After that, signals from the broadband and narrowband service processing modules are aggregated to the forwarding module. The forwarding module reassembles the cell flow into PTM packets, encapsulates the 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 GE or 10GE interface.
  • In the downstream direction, the forwarding module decapsulates the IP packets sent from the backplane bus, performs CAR on the packets, reassembles the packets into PTM packets, and then transmits them to the broadband and narrowband service processing modules. The interface module then converts the PTM packets into analog signals, and transmits the analog signals over the subscriber line through the splitter module.

Front Panel Port



  • When cables from the LINE ports are routed to an outdoor environment or the user side, the MDF must be installed with a protective unit.
