DS2155
T1/E1/J1 Single-Chip Transceiver
T1/E1/J1 Single-Chip Transceiver Provides Single Application Design for World-Wide Interoperability
|
Status
Active: In Production.
Description
The DS2155 is a software-selectable T1, E1, or J1
single-chip transceiver (SCT) for short-haul and
long-haul applications. 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, and -22.5dB. E1 waveform
generation includes G.703 waveshapes for both 75Ω
coax and 120Ω twisted cables. The receive interface
provides network termination and recovers clock and
data from the network.
