H801TOPA Board Description

H801TOPA Board Description

The H801TOPA is a TDM traffic over PSN board. It uses the daughter board to transmit services upstream.

Functional Specifications

The H801TOPA board supports the following functions:

  • Native TDM function (when the NH1A/O2CE daughter board is configured)
  • CESoP function (when the EH1A/CSSA daughter board is configured)
  • TDM signal upstream transmission through the 16 channels of E1 port (when the NH1A/EH1A daughter board is configured)
  • TDM signal upstream transmission through the 2 channels of STM-1 optical port (when the O2CE/CSSA daughter board is configured, )

Technical Specifications

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

Working Principle

Figure 3-60  Working principle of the H801TOPA board

The basic working principle of the H801TOPA board is as follows:

  • The control module loads the board software, controls, and manages the entire board.
  • The service processing module allocates the GE bus of the backplane and processes signals.
  • The interface module converts signals.
  • 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, after passing the interface module, the GE signals from the backplane are converted into the TDM frames. Then, the TDM frames are transmitted upstream.
  • In the downstream direction, the interface module receives the signals from the TDM line, and converts and encapsulates the signals into GE packets. After being transmitted to the backplane bus through the service processing module, the GE packets are transmitted to the control board. Then, the control board forwards the GE packets to the related service boards.

NOTE:
  • In Table 3-33, the first letter "R" or "T" in each cell of the signal column refers to "Receive" or "Transmit" of E1 signals.
  • In Table 3-33, the second letter "R" or "T" in each cell of the signal column refers to "ring" or "tip" of the 75-ohm E1 signal cable, or refers to sign + or – of the 120-ohm E1 signal cable.

Jumper Settings for the NH1A Daughter Board

Whether the cable is grounded on the NH1A daughter board can be set through the jumpers. The NH1A daughter board has four sets of jumpers: J7, J8, J9, and J10. The four sets of jumpers should be set to function at the same time. Table 3-34 describes the settings of J7, J8, J9, and J10.

Table 3-34  Jumper settings for the NH1A daughter board

Status

Description

ON (jumper caps are installed)

The jumper caps should be installed (which means grounded) if the transmit and receive resistance is 75 ohms.

OFF (jumper caps are removed)

The jumper caps should be removed (which means ungrounded) if the transmit and receive resistance is 120 ohms.

NOTE:

Generally, the coaxial cables connected to the E1 port are unbalanced cables with the resistance of 75 ohms; the twisted pairs connected to the E1 port are balanced cables with the resistance of 120 ohms. The interference source can affect the transmission of analog signals to a great extent. Therefore, the connection mode and grounding mode must be correct and reliable; otherwise, bit error or error message about signal loss may occur.

Daughter Board

To provide the related functions, the H801TOPA board must be configured with a matching daughter board. Figure 3-61 shows the position of the daughter board (NH1A and EH1A) on the H801TOPA board. Figure 3-62 shows the position of the daughter board (O2CE and CSSA) on the H801TOPA board.
