Huawei SLQ1 SSN1SLQ1A-80km OSN3500 Base Station Product Description: Version Description The SLQ1A is available in one functional version, namely, N1. Through the board version replacement function, the N1SLQ1 and the N1SLQ1A can substitute each other. Version Mapping Board Start Version N1SLQ1A V100R008C01 Parent topic: SLQ1A Board Updates This section describes the hardware updates in V200R013C30 and later versions as well as the reasons for the updates. Any product versions that are not listed in the document means that they have no hardware updates. Parent topic: SLQ1A Application The SLQ1A is a line board. The SLQ1A can be used on the OptiX OSN equipment series to transmit and receive STM-1 optical signals. The SLQ1A converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SLQ1A converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals. Figure 1 shows the application of the SDH processing boards. The SDH processing boards can form a ring network or a chain network in the system. Figure 1 Networking and application of the SDH processing boards Functions and Features The SLQ1A transmits and receives STM-1 optical signals, performs O/E conversion for the STM-1 optical signals, extracts and inserts overhead bytes, and generates alarm signals on the line. Table 1 provides the functions and features of the SLQ1A. Table 1 Functions and features of the SLQ1A Function and Feature SLQ1A Basic functions Transmits and receives 4xSTM-1 optical signals. Specifications of the optical interface Supports different types of standard optical interfaces, namely, the I-1, S-1.1, L-1.1, L-1.2, Ie-1, and Ve-1.2.
