TP3410
ISDN Basic Access Echo-Cancelling 2B1Q U Transceiver
General Description
The TP3410 is a complete monolithic transceiver for ISDN
Basic Access data transmission at either end of the U inter-
face. Fully compatible with ANSI specification T1.601, it is
built on National’s advanced double-metal CMOS process,
and requires only a single +5V power supply. A total of
160 kbps full-duplex transmission on a single twisted-pair is
provided, with user-accessible channels including 2 “B”
channels, each at 64 kbps, 1 “D” channel at 16 kbps, and an
additional 4 kbps for loop maintenance. 12 kbps of band-
width is reserved for framing. 2B1Q Line coding is used, in
which pairs of binary bits are coded into 1 of 4 quantum lev-
els for transmission at 80k symbols/sec (hence 2 Binary/1
Quaternary). To meet the very demanding specifications for
<
1 in 10e7 Bit Error Rate even on long loops with crosstalk,
the device includes 2 Adaptive Digital Signal Processors, 2
Digital Phase-locked Loops and a controller for automatic
activation.
The digital interface on the device can be programmed for
compatibility with either of two types of control interface for
chip control and access to all spare bits. In one mode a Mi-
crowire serial control interface is used together with a 2B+D
digital interface which is compatible with the Time-division
Multiplexed format of PCM Combo
devices and back-
planes. This mode allows independent time-slot assignment
for the 2 B channels and the D channel.
Alternatively, the GCI (General Circuit Interface) may be se-
lected, in which the 2B+D data is multiplexed together with
control, spare bits and loop maintenance data on 4 pins.
