H801CITD Board Description

H801CITD Board Description

The H801CITD board is a combo interface transfer board. It provides the input and output clock source for the system and supports functions such as input and output of alarm digital parameters.

NOTE:

As shown in Figure 3-41, the H801CITD board has the following changes after an upgrade from Ver.A to Ver.B:

  • Ports are adjusted by 180 degrees.
  • An ejector lever is added, facilitating board insertion and removal.
Figure 3-41  Differences in appearance between Ver.A and Ver.B

Functional Specifications

The H801CITD board supports the following functions:

  • Seven inputs of alarm digital parameters and one output of digital controlling parameters
  • External monitoring Ethernet port to transparently transmit monitored data
  • When configured with the BITSB clock daughter board, the CITD board also provides the following functions:
    • Two inputs of 2 Mbit/s or 2 MHz BITS clock signals
    • Two inputs of 1 PPS+TOD time signals(supported in V800R013C10 and later versions)
    • One output of 2 Mbit/s or 2 MHz clock signals
    • One output of 1PPS time signals (supported in V800R013C10 and later versions)

Technical Specifications

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

Working Principle

Figure 3-42  Working principle of the H801CITD board

The H801CITD board consists of the control module, interface module, power module, and clock module. The basic working principle of the H801CITD board is as follows:

  • The control module controls each functional module of the board and reads the vendor information about the power board, service board, and BITS daughter board.
  • The interface module provides the BITS clock port, time port, GE transparent transmission port, and alarm port.
  • The BITS clock daughter board recovers the 2 Mbit/s clock signals or shapes the 2 MHz clock signals, which can function as the system clock source.
  • The power module supplies power to each functional module of the board and +5 V DC power to the backplane and the power board.
  • The clock module provides clock signals for each functional module of the board.
