H801VSNF Board Description

H801VSNF Board Description

The H801VSNF is a 48-port VDSL2 over POTS splitter board that supports real impedance (600 ohms). It separates 48 channels of VDSL signals from POTS signals. The separated VDSL2 signals are transmitted to the VDSL2 service board, and the separated POTS signals are transmitted to the PSTN switch device.

Functional Specifications

The H801VSNF board supports the following function:

  • Separating 48-channel VDSL2 signals from POTS signals
  • Real impedance (600 ohms)

Figure 3-159 shows the external connections of the H801VSNF board.

Working Principle

The H801VSNF board consists of two parts: splitter module and protection module. The splitter module separates the VDSL signals and the POTS signals. The protection module supports the over-voltage protection of the LINE line.

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 xDSL port, LINE port, and PSTN port on the H801VSNF board are the same. For pin assignment of the xDSL0 port, see Table 3-210; for pin assignment of the xDSL1 port, see Table 3-211.
