DS3 Framer TXC-03401B DATA SHEET DESCRIPTION
The DS3F is designed for DS3 framer applications in which broadband payloads are mapped into the 44.736 Mbit/s DS3 frame format. Although the C-bit parity format is remended, the DS3F can also operate in the M13 mode. In the C-bit parity format, the DS3F provides a separate interface for selected C-bits. The DS3F also provides for transmitting and receiving the FEAC channel and Blue code AIS conditions, and generates and detects DS3 AIS, DS3 idle, P-bit parity and C-bit parity. In addition, performance counters are provided, as well as the ability to generate single framing, FEBE, C-bit parity and P-bit parity errors. The device also provides X-bit inversion, receive loop timing and indications for FEAC idle channel, FEAC word stack overflow and Severely Errored Frame. The payload interface is selectable through software as...
