DESCRIPTION
The ST5421 (SID-GCI) is a complete monolithic
transceiver for data transmission on twisted pair
subscriber loops. It is buIlt on SGS-THOMSON
HCMOS 3A double metal advanced process, and
requires only a single + 5V supply. AII functions
specified in CCITT recommendation I.430 for
ISDN basic access at the ’S’ and ’T’ interfaces
are provided, and the device can be configured to
operate either in TE (Terminal Equipment), in
NT1 or NT2 (Network Termination) or in PABX
line-card device.
GCI interchip interface highly enhances device
connection efficiency by multiplexing controls and
data on the same bus and requiring only 4 pins.
ST5421 implements all the GCI standard func-
tions for Monitor and Control/Indicate channels,
supporting up to 8 GCI peripherals in multiplexed
mode.
As specified in I.430, full-duplex transmission at
192kb/s is provided on separate transmit and re-
ceive twisted wire pairs using inverted Alternate
Mark Inversion (AMI) line coding. Various chan-
nels are combined to form the 192kb/s aggregate
rate, including 2 ’B’ channels, each of 64kb/s, and
1 ’D’ channel at 16kb/s. In addition, multiframe
transmission is provided in a switchable process-
ing mode based on United State ANSI standard
for Layer 1 maintenance. 800 bit/s message ori-
ented data transmission is supported by S1 and
Q channels.
