NEW FEATURES
§ Additional hardware signaling capability including:
– Receive signaling re-insertion to a backplane multiframe sync
– Availability of signaling in a separate PCM data stream
– Signaling freezing
– Interrupt generated on change of signaling data
§ Full HDLC controller with 64–byte buffers in both transmit and receive paths. Configurable for FDL
or DS0 access
§ Per–channel code insertion in both transmit and receive paths
§ Ability to monitor one DS0 channel in both the transmit and receive paths
§ RCL, RLOS, RRA, and RAIS alarms now interrupt on change of state
§ Detects AIS-CI
§ 8.192 MHz clock synthesizer
§ Per–channel loopback
§ Ability to calculate and check CRC6 according to the Japanese standard
§ Ability to pass the F–Bit position through the elastic stores in the 2.048 MHz backplane mode
§ IEEE 1149.1 support
§ FEATURES
§ Four T1 DS1/ISDN–PRI/J1 framing transceivers
§ All four framers are fully independent
§ Frames to D4, ESF, and SLC–96 R formats
§ Each of the four framers contain dual two–frame elastic store slip buffers that can connect to
asynchronous backplanes up to 8.192 MHz
§ 8–bit parallel control port that can be used directly on either multiplexed or non–multiplexed buses
(Intel or Motorola)
§ Extracts and inserts robbed bit signaling
§ Detects and generates yellow (RAI) and blue (AIS) alarms
§ Programmable output clocks for Fractional T1
§ Fully independent transmit and receive functionality
§ Generates and detects in–band loop codes from 1 to 8 bits in length including CSU loop codes
§ Contains ANSI one’s density monitor and enforcer
§ Large path and line error counters including BPV, CV, CRC6, and framing bit errors
§ Pin compatible with DS21Q44 E1 Enhanced Quad E1 Framer
§ 3.3V supply with 5V tolerant I/O; low power CMOS
§ Available in 128–pin TQFP package
