Patent Number 5040170 ISSUE 1 May 1995 Ordering Information MT90733AP 68 Pin PLCC -40° to 85°C Description The MT90733 DS3 Framer (DS3F) is designed for mapping broadband payloads into the DS3 frame format, which meets ANSI’s T1.
107-1988 and supplement T1.
107a-1990.
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 C-bits.
The DS3F also provides software access for transmitting and receiving the FEAC channel, and generates and detects DS3 AIS, DS3 idle, Pbit 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 payload interface is selectable through software as either a bit-serial or nibble-parallel format.
