GENERAL DESCRIPTION

FEATURES

Cꢀ Four Complete E1 (CEPT) PCM-30/ISDN-PRI

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.
