MK50H28 - MULTI LOGICAL LINK FRAME RELAY CONTROLLER

Datasheet Summary

Description

The STMicroelectronics MK50H28 Multi-Logical Link Communications Controller is a CMOS VLSI device which provides link level data communications control for Frame Relay Applications on Permanent Virtual Circuits (PVCs).

Features

  • Based on ITU Q.933 Annex A and T1.617 Annex D Standards for Frame Relay Service and Additional Pocedures for Permanent Virtual Circuits(PVCs). Optional Transparent Mode (no LMI Protocol Processing - all frame data received). Local Management Link Protocol with optional Bi-directional message processing. Detects and indicates service-affecting errors in the timing or content of events. Programmable Timers/Counters: nT1/T391, nT2/T392, nN1/N391, nN2/N392, nN3/N393 and dN1 for the LMI/LIV channel.
