1.0 Product Description
CN8330
DS3/E3 Framer with 52 Mbps HDLC Controller
Configuration, control, and monitoring of the CN8330 termination circuit and
framer are accomplished with a selectable microprocessor control mode that
monitors all status conditions and provides configuration control. In DS3 mode a
stand-alone mode of operation is featured. This allows the circuit to operate as a
monitor and provide status and alarm indications to external processing or
counting circuitry including:
• AIS, all-ones
• Yellow alarm
• Loss of signal
• Idle code detection
• Out-of-frame and frame-bit error counting
• Parity error
• LCV (Line Code Violation)
• Path parity
• X-bit disagreement
• FEBE event counting
The received DS3 C-bits (or E3 N-bits) are directed to an external pin to
provide visibility for external processing, as required.
