H802EDTB Board Description

H802EDTB Board Description

The H802EDTB board is a 16 port SHDSL and 16 port E1 service board. It provides 16 channels of TDM SHDSL access services and 16 channels of E1 and V.35 access services. The H802EDTB board supports E1 services over SHDSL lines and achieves transparent transmission and convergence for services from E1 ports to SHDSL ports.

NOTE:

After the H802EDTB board is upgraded from VER.B to VER.C, all functions remain unchanged.

Feature and Specifications

Please refer to "Voice Board Comparison".

Technical Specifications

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

Working Principle



The H802EDTB board provides two 8-channel E1 ports and one 16-channel SHDSL port and its basic working principle is as follows:
  • The control module controls the board, and loads and configures the service processing logic. The LocalBus and MII interfaces are for the service processing module.
  • The service processing module implements switching of the time division multiplexing (TDM) timeslots and IP packets distribution inside the board, configures and controls the E1 ports, and provides the HDLC channel for its communication with the control board. In addition, the service processing module supports packet filtering, traffic control, and encryption.
  • The E1 interface module provides 16 channels of E1 access services and signal conversion.
  • The DSP module supports processing of 420-channel DSP packet voice services to implement the connection of VoIP service to the broadband IP network, and also supports the processing of the IP voice protocols such as H.248 and MGCP.
  • The SHDSL module provides 16 channels of TDM SHDSL services to extend the transmission distance of 16 channels of E1 services. In addition, the SHDSL module can be connected to the PRA PBX.
  • The power module supplies power to each functional module of the board.
  • The clock module extracts the clock signals and generates the clock signals required by the system.
  • The clock module provides working clock for the board chip.

Jumper Settings

The H802EDTB board provides five sets of jumpers, as shown in Figure 3-100.

Figure 3-100  Layout of the jumpers on the H802EDTB board

The jumpers support the following functions:

  • Jumpers J15, J16, J17, and J18 are used to set whether to ground the shield layer of the E1 port.
    • The jumper caps should be removed (which means ungrounded) if the transmit and receive resistance is 120 ohms.
    • The jumper caps should be installed (which means grounded) if the transmit and receive resistance is 75 ohms.
  • Jumpers J11 and J21 are used to query through software whether the shield layer of the E1 port is grounded (a reserved function) . The setting of jumper J11 must be the same as that of jumper J21.
  • It is recommended that the settings of jumpers J15, J16, J17, and J18 be the same as those of jumpers J11 and J21.

Table 3-78 describes the jumper settings for the H802EDTB board.
