Description

The DS21Q55 is a quad software-selectable T1, E1, or J1 MCM device for short-haul and long-haul applications. Each port is composed of a line interface unit (LIU), framer, HDLC controllers, and a TDM backplane interface, and is controlled by an 8-bit parallel port configured for Intel or Motorola bus operations. The DS21Q55 is software compatible with the DS2155 single-chip transceiver. It is pin compatible with the DS21Qx5y family of products.
