TXC-03401B Datasheet (Transwitch) - DS3F Device DS3 Framer

TXC-03401B, DS3F Device DS3 Framer

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 recommended, the DS3F can also operate in the M13 mode.

In the C-bit parity format, the DS3F provides a separate interface for selected

Detect and generate DS3 AIS, and idle signals Transmit reference generator for serial operation Transmit and receive Far End Alarm and Control (FEAC) with double word capability and automatic transmission Maskable hardware interrupt for eight alarms Transmit single errors: framing, FEBE, C-bit parity, and P-bit parity FEBE, C-bit, and P-bit performance counters Counters for F-bit and M-bit errors Counter for coding
