    SOH Processing Ethernet Network Card Seamless Switch Supported STM-1 Link

    SOH Processing Ethernet Network Card Seamless Switch Supported STM-1 Link

    Overview

    The O155-8 card is used as a tributary card or a line card in the system to implement the access and processing of eight STM-1 optical interface services.

    • Provides eight STM-1 optical interfaces.

    • Supports transparent transmission of overheads.

    • Supports the test on performance such as optical power, laser bias current and bit error.
      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 STM-1 link 1+1 / 1:1 protection.

    • Supports hot insertion at the STM-1 optical interfaces.

    • Supports the automatic shutdown of the laser.

    • Supports the seamless switch between the active and standby clock and crossconnect cards.

    • Supports the remote software upgrade.
