O155 /155m Fiberhome Ibas 110A Equipment Extension Card Bidirectional Pointer Processing

O155 /155m Fiberhome Ibas 110A Equipment Extension Card Bidirectional Pointer Processing

The main functions of the O155 card include

• It provides one channel of STM-1 optical interface TX / RX with SC connectors adopted.
• It adds 16 optional channels of 2048 kbit/s E1 interfaces and thus it can perform two channels of STM-1 higher order signals processing as well as timing generation, resuming, mapping and demapping functions of 16 channels of 2048 kbit/s signals.
• It completes O / E conversion, clock extraction and integration, HDB3 coding, decoding, multiplexing and demultiplexing.
• It completes extraction and insertion of the dedicated overheads E1, E2, F1 and S1 in RSOH / MSOH.
• It performs bidirectional pointer processing, bus switching and 1＋1 line protection switching.
• The DCC, either DCCR or DCCM, is sent under point-to-point mode.
• It supports remote downloading functions of FPGA and BCT programs.
