TP3420A

ISDN S/T Interface Device

General Description

Features

n 2 B + D 4-wire 192 kb/s transceiver

n Selectable TE or NT mode

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.

n Exceeds I.430 range: 1.5 km point-to-point

n Adaptive receiver for high noise immunity

n Adaptive and fixed timing options for NT-1

n Clock resynchronizer and elastic buffers for NT-2/LT

n Slave-slave mode for NT-2 trunks

n Extensive hardware support for SC1, SC2 and Q

channel messaging

n Bipolar violation detection and FECV messaging

n Selectable system interface formats

n MICROWIRE and SCP compatible serial control

interface

n TP3054/7 Codec/Filter COMBO compatibility

n Single +5V supply

™

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

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.

™

n 20-pin package DIP, PLCC

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.

Applications

n Same Device for NT, TE and PBX Line Card

n Point-to-Point Range Extended to 1.5 km

n Point-to-Multipoint for all I.430 Configurations

n Easy Interface to:

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 capacitance cable, and

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.
