DS21Q44 - Enhanced QUAD E1 FRAMER

General Description

The DS21Q44 E1 is an enhanced version of the DS21Q43 Quad E1 Framer.

The DS21Q44 contains four framers that are configured and read through a common microprocessor compatible parallel port.

Key Features

  • Four E1 (CEPT or PCM-30) /ISDN-PRI framing transceivers All four framers are fully independent; transmit and receive sections of each framer are fully independent Frames to FAS, CAS, CCS, and CRC4 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) Easy access t.
