O155 STM-1 Fiberhome IBAS 180 Timing Generation Recovery Function Bidirectional Processing

Overview

The main functions of this card are as follows:

There are two optical interfaces and sixteen 2Mbit/s E1 interfaces for the processing of two channels of STM-1 higher order signal and timing generation recovery, mapping and demappping of sixteen channels of 2Mbit/s signal;
Accomplish E/O conversion, clock extraction and synthesis, HDB3 coding and decoding, multiplex and de-multiplex;
Accomplish the extraction and insertion of dedicated overhead E1, E2, F1 and S1 in RSOH/MSOH;
Bi-directional pointer processing, bus conversion and 1+1 linear protection switching;
Transmit DCC in point-to-point mode and can select DCCR or DCCM to transmit;
Support remote download function of FPGA and BCT program.
