The is a three-channel, DS3/E3/STS-1, fully integrated Line Interface Unit Distinguishing Features (LIU) device. It is configured via external pins and does not require a microprocessor Programmable pulse shaper to meet interface. Each channel has an independent receive equalizer requiring no user cross-connect pulse masks (ANSI T1.1021993) configuration. Additionally, each channel has a programmable transmit pulse shaper Meets jitter tolerance and jitter generation that can be set to ensure that the transmit pulse meets the pulse mask requirement specifications of Bellcore GR499, GR253, for the digital cross-connect. The is a dual-channel, and the is a and ETSI TBR24 single-channel LIU with performance identical to the M28333.

The M28333 gives the user new economies of scale in concentrator applications where three or STS-1 channels are concentrated into a single STS-3 channel. a capacitor. The Transmit Line Driver Monitor checks for a faulty transmitter or shorted output.

Each line interface is reduced to 1:1 coupling transformers, terminating resistors, and
