    Overview

    The O622-4 card is used as a tributary card or a line card in the system to implement the access and processing of four STM-4 optical interface services.


    The main functions of the card are as follows:

    • Provides four STM-4 optical interfaces.
    • Supports transparent transmission of overheads.
    • Supports the test on performance such as optical power, laser bias current and bit error.
    • Performs the 4:1 / 1:4 multiplexing and demultiplexing.
    • Supports the SOH processing and supports all the defined SOH bytes (such as A1, A2, J0, B1, B2, S1, M1, H1, H2, H3, E1, E2, F1, D1 to D12, K1 and K2).
    • Supports monitoring of the higher order path overheads (such as J1, B3, C2 and G1).
    • Supports the equipment loopback and line loopback tests.
    • Supports the contiguous concatenation of VC-4-4c. u Supports hot insertion at the STM-4 optical interfaces. u Supports 1+1 / 1:1 protection for STM-4 line interfaces of the card.
    • Supports the seamless switch between the active and standby clock and crossconnect cards.
    • Supports the automatic shutdown of the laser.
    • Supports the remote software upgrade.
