Telenetics TUTA220 is a high speed terminal
adapter with an integral U interface designed to
provide users simple access to the data
transmission capabilities of the ISDN Basic Rate
Interface. It provides access to two 64-kbps
B-channels for circuit switched or nailed up
calls, and to a 16-kbps D-channel for transferring
signaling information. The D-channel also provides
access to D-channel packet service.
TUTA220 allows you to connect two terminals, PCs
or other data terminal equipment to the ISDN for
data communications over a single Basic Rate
Access line, using either circuit-switched or X.25
packet calls. The 2-port configuration supports
synchronous or asynchronous data utilizing a
variety of protocols.
with AT 5ESS, Northern Telecom DMS-100 central
office switches and all National ISDN-1 switches
and with multiple rate adaption protocols, the
TUTA220 gives you the versatility you need to meet
the requirements at many different sites.
TUTA220 also supports economical new IDSL, or
2B1Q, Services that provide 2 wire leased line
digital transmission to 128Kbps.
TUTA220 allows asynchronous data transfer at 300
bps to 115.2 kbps and synchronous data transfer
from 1200 bps to 128 kbps. EIA-232, EIA-366 and
CCITT V.35 interfaces are available to meet your
connection requirements. With D-channel X.25
packet support, the TUTA220 processes asynchronous
data using its internal PAD (CCITT X.3, X.28, X.29
compliant) for transmission with LAPD protocol on
with a convenient 32-character LCD front panel,
the TUTA220 menu selections are made with three
pushbuttons (YES, NO, HOME) in response to menu
prompts. The standalone model has a full numeric
keyboard which can be used to dial data calls
directly and also simplifies menu selection entry.
The rack-mount card has a three pushbutton and LCD
panel only. The LCD menu can be used to configure
any port, channel, session or global parameters.
Other menu functions include display of status of
any port or channel and make or end ISDN calls for
TUTA220 is available both as a standalone model
and as a card that fits in the Universal Data
300 to 115200 bps asynchronous; 1200 to 128000 bps
synchronous -- Will accommodate a wide range of DTE
to ISDN Basic Rate Interface (2B+D)
Provides access to two 64-kbps B-channels for circuit
switched calls and to a 16-kbps D-channel for transferring
signaling information, or access to D-channel packet
service. U interface does not require use of a separate
NT1 unit. Also provides interface to IDSL (ISDN Digital
Subscriber Line) 2B1Q service supporting 2wire leased line
to 128Kbps without signaling.
The 2-port model supports synchronous or asynchronous
Combines B-channels for synchronous data rates of 56,
64, 112, or 128 kbps.
X.25 packet support
Provides access to a wide variety of packet switched

Display plus six LEDs allows configuring the unit from
the front panel. Also allows viewing current configuration
and status without causing an interruption of data.
Simplifies front panel configuration and dialing.
Accommodates a wide variety of DTE equipment.
Command Set Compatible
Compatible with a wide variety of asynchronous software
Supports CCITT dialing protocols.
Compatible with existing base of installed equipment,
including video conferencing units.
Allows easy access to options. Allows calls to be
originated from any port.
Diagnostic Test Modes
Allow rapid isolation of communications faults.
Minimize down time.
UTA 220DL uses FLASH ROM to allow easy product
When communications faults occur, the following TUTA220
integral test features help isolate the source of the
failure: Self test, 2B+D loopback, Digital loopback, Local
terminal loopback, Local loopback, and Terminal loopback.
For simple configuration and operation, the TUTA220 can be
completely programmed using the front panel keys and LCD.
Responding to the LCD menu prompts with the YES, NO, and
HOME keys lets you program all operating parameters and
options. The display also shows system status, keeping you
informed on call progress and operations.
