DESCRIPTION

The SGS-THOMSON Signalling System #7 Sig-

nalling Link Controller (MK5027) is a VLSI semi-

conductor device which provides a complete link

control function conforming to the 1988 CCITT

version of SS7. This includes frame formatting,

transparency (so called ”bit-stufling”), error recov-

ery by two types of retransmission, error monitor-

ing, sequence number control, link status con-

trol, and FISU generation. One of the outstanding

features of the MK5027 is its buffer management

which includes on-chip DMA. This feature allows

users to handlq multiple packets of receive and

transmit data at a time. (A conventional data link-

control chip plus a separate DMA chip would han-

dle data for only a single block at a time.) The

MK5027 may be used with any of several popular

16 and 8 bit microprocessors, such as 68000,

6800, Z8000, Z80, LSI-11, 8086, 8088, 8080, etc.
