GENERAL DESCRIPTION
The DS21Q58 E1 quad transceiver contains all the
necessary functions for connecting to four E1 lines.
The DS21Q58 is a direct replacement for the
DS21Q50, with the addition of signaling access and
improved interrupt handling. It is composed of a line
interface unit (LIU), framer, and a TDM backplane
interface, and is controlled through an 8-bit parallel
port configured for Intel or Motorola bus operations or
serial port operation.
