Product Summary
The DS21455+ is a quad monolithic device featuring independent transceiver that can be software configured for T1, E1, or J1 operation. Each is composed of a line interface unit (LIU), framer, HDLC controllers, and a TDM backplane interface, and is controlled via an 8-bit parallel port configured for Intel or Motorola bus operations. The DS21455+ is a direct replacement for the older DS21Q55 quad MCM device.
