DS2181A CEPT Primary Rate Transceiver

The DS2181A is designed for use in CEPT networks and supports all logical requirements of CCITT Red Book Recommendations G.704, G.706 and G.732. The transmit side generates framing patterns and CRC4 codes, formats outgoing channel and signaling data, and produces network alarm codes when enabled. The receive side decodes the incoming data and establishes fra.
