TP3420A
ISDN S/T Interface Device
General Description
The TP3420A is an enhanced version of the TP3420, with a
number of upgraded features for compliance with the new
release of ANSI T1.605-1991 and CCITT I-430. At initial
power-up the device is fully backwards compatible with the
TP3420 device, and modifications to the firmware are only
required to take advantage of the new features.
The TP3420A S Interface Device (SID
) is a complete
monolithic transceiver for data transmission on twisted pair
subscriber loops. It is built on National’s advanced 1.0 mi-
cron double-metal CMOS process, and requires only a
single +5V supply. All functions specified in CCITT recom-
mendation I.430 (1991) and ANSI T1.605 (1991) for ISDN
basic access at the “S” and “T” interfaces are provided, and
the device can be configured to operate either in a TE (Ter-
minal Equipment), in an NT-1 or NT-2 (Network Termination)
or as a PABX line-card or trunk-card device.
As specified in I.430, full-duplex transmission at 192 kb/s is
provided on separate transmit and receive twisted wire pairs
using inverted Alternate Mark Inversion (AMI) line coding. 2
“B” channels, each of 64 kb/s, and 1 “D” channel at 16 kb/s
are available for users’ data. In addition, the TP3420A pro-
vides the 800 b/s “S1”, “S2” & “Q” multiframe channels for
Layer 1 maintenance.
All I.430 wiring configurations are supported by the TP3420A
SID, including the “passive bus” for up to 8 TE’s distributed
within
200
meters
of
low
point-to-point and point-to-star connections up to at least
1500 meters (24AWG). Adaptive receive signal processing
ensures low bit error rates on any of the standard types of
cable pairs commonly found in premise wiring installations
when tested with the noise sources specified in I.430.
