The DS2155 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 DS2155 is pin and software compatible with the DS2156. The LIU is composed of transmit and receive interfaces and a jitter attenuator. The transmit interface is responsible for generating the necessary waveshapes for driving the network and providing the correct source impedance depending on the type of media used. T1 waveform generation includes DSX-1 line buildouts as well as CSU line buildouts of -7.5dB, -15dB, a.
