• Frames to a DS2 (ANSI T1.107 section 8) signal with a maximum average
• Detects the DS2 alarm indication signal (AIS) in 9.9 ms in the presence of a 10 -3
• Extracts the DS2 X-bit remote alarm indication (RAI) bit and indicates far end
• Accumulates up to 255 DS2 M-bit or F-bit error events per second.
• Generates the required X, F, and M bits into the transmitted DS2 bit stream.
• Provides for transmission of far end receive failure (FERF) and alarm indication
• Provides optional automatic insertion of far end receive failure (FERF) on
• Multiplexes four DS1 or three 2048 kbit/s (according to ITU-T Rec. G.747) bit
• Performs required bit stuffing including generation and interpretation of C-bits.
• Includes required FIFO buffers for rate adaptation in the multiplex path.
• Performs required inversion of second and fourth multiplexed DS1 streams as
• Allows insertion and detection of per DS1 payload loopback requests encoded in

associated bit has been in the same state for two consecutive frames. The
status is buffered for six M-frames, ensuring a better than 99.9% chance of
freezing the correct status for the duration of the out of frame occurrence.
