T9000
ISDN Network Termination Node (NTN) Device
1 Description
The T9000 is an ISDN network termination node
device that is highly integrated and provides a low-
cost solution to support the following:
I
All standard NT1 functions required to attach an
S/T interface device to an ISDN network. In addi-
tion, the T9000 also supports attachment of two
standard analog (POTS) telephones for communi-
cations over an ISDN network.
I
Intelligent network termination (INT/Smart NT1)
functions, with its built-in controller and support for
attachment of two analog phones for communica-
tions over an ISDN network.
I
A variation of the V5.1 signaling protocol called
narrowband multiservice delivery system (NMDS)
adopted by countries using the V5 signaling proto-
col (e.g., United Kingdom)
In addition, the T9000 can also be used for pair-gain
applications where support for more than one tele-
phone line is required without the installation of an
additional pair of wires from the telephone central
office to the customer premises.
2 Features
I
Complete interface to basic rate ISDN networks at
the S/T-interface and U-interface reference points.
I
U-interface (LT or NT operation) conforms to
ANSI* T1.601 and ETSI TS 080 standards.
I
S/T-interface conforms to ANSIT1.605 standard,
ITU-T I.430 recommendation, and ETSI ETS 300
012 standard for the network termination (NT) side
of the network.
I
Low power consumption.
I
D-channel HDLC formatter with address recogni-
tion and integrated contention resolution scheme.
I
64-byte D-channel FIFOs.
I
GCI+ interface supporting GCI and generic TDM
modes for interfacing to a wide variety of POTS cir-
cuits.
I
General-purpose I/O (GPIO) ports with interrupt
capability for interfacing to SLICs, codecs, DTMF
decoders, and other peripheral devices.
I
Three low-power, general-purpose comparators.
I
Two 100 kHz programmable PWM outputs with an
automatic sine wave generation mode to support
ringing, pulse metering, etc.
I
20 kHz—200 kHz programmable dc/dc converter
synchronization output.
I
JTAG boundary scan on all digital pins.
I
Power-saving mode.
— In this mode, the unused interfaces of the
T9000, such as, microcontroller, PWMs, and
comparator can remain in powerdown mode,
thus resulting in significant reduction in power
consumption (see Section 20.2, Power Con-
sumption).
I
Packaged in a 100-pin TQFP (thin quad flat pkg).
I
5 V power supply.
I
Operating temperature range: –40 °C to +85 °C.
I
Integrated 80C32 microcontroller with the following
features:
— Programmable clock rates (MHz): 15.36, 7.68,
3.84, 1.92, 0.96.
— 4K internal SRAM.
— 64K internal ROM.
— Supports external ROM/RAM.
— Can be disabled via pin strap (sleep mode) for
use with an external emulator.
— Programmable watchdog timer.
External ROM and RAM (64K x 8 maximum each)
are accessed through an external data/address bus.
Support for ROM and RAM space above the 64K
limit can be accomplished by memory paging using
one or more GPIO signals as an external chip select.
Power management routines may be implemented
through the microcontroller to power down most of
the internal submodules, including the microcontrol-
ler itself. An autosleep mode is also included, allow-
ing the microcontroller to stop its internal clock and
be automatically restarted (microcontroller wake-up)
whenever any interrupt is triggered.
