Introduction
ELSA TanGo 2000 one of the family of ISDN products from ELSA. It is an external
terminal adapter for connecting your PC to an ISDN Basic Rate Interface point-to-point or
point-to-multipoint connection, or to private branch exchanges (PBX systems) with an S0
interface. In addition to the advantages of ISDN technology such as high-speed Internet
access, the
ELSA TanGo 2000 analog connectors (a/b ports) provide access to the
advanced features of digital exchanges such as call waiting, alternating, three-party
conferencing, call forwarding or connections without dialing. In addition, you can keep
track of your calling charges with the charge monitor. The hardware installation is fast
and user-friendly thanks to Plug&Play support (see Installation Guide).
Highlights of the
ELSA TanGo 2000
The following is an outline of the essential technical features of the ISDN terminal
adapter to provide a quick overview of its performance:
KTransmission modes –
ELSA TanGo 2000 supports the following transmission
modes and speeds:
HDLC-PPP Internet providers can be reached using PPP protocol.
X.75
ELSA TanGo 2000 supports X.75/T.70NL connections.
V.120 The
ELSA TanGo 2000 also supports the ITU-T V.120 (I.465)
recommendation at 56,000 and 64,000 bps.
Ka/b ports –
ELSA TanGo 2000 provides two connectors (a/b ports) for analog
terminal equipment. You can thus continue using your analog equipment such as
telephones, answering machine or fax.
KFlash ROM technology – Firmware updates can be performed quickly and easily
using the command AT$UPX. This provides a convenient way to equip your unit
with future functions.
KAutomatic protocol detection – Depending on its configuration, the terminal
adapter supports automatic detection of the X.75, V.120 and HDLC-PPP protocols for
incoming and outgoing connections.
KAutomatic detection of 56,000 and 64,000 bps – If an incoming connection with
56,000 bps is indicated in the D channel (e.g. from the USA), the X.75 and V.120
protocols automatically switch to 56,000 bps.
KD channel protocols – The command AT$IDP can be used to switch between the
DSS1 protocol (Euro-ISDN) and the 1TR6 protocol (national ISDN). The DSS1
protocol is the default selection.

KTerminal selection digits and MSN – The ISDN terminal adapter supports the
setting and querying of terminal selection digits via the command AT$IEAZ and
multiple subscriber numbers (MSN) via the command AT$IMSN.
KDelayed call answering – This function permits the delayed answering of
incoming calls. This can be useful if several terminal adapters with the same
terminal selection digit or MSN (multiple subscriber number) are connected to one
ISDN SO interface. Delayed call answering can be set using the S152 register.
KDial number lock – The terminal adapter can be locked for outgoing calls with
specific dial numbers using the command AT$INCB. A connection will not be
established if the first digits of the number dialed correspond to the locked number
(maximum of 5 digits).
KUser groups – The verification of the caller IDs of incoming calls can be set with
the command AT$ICLD and permits the creation of closed user groups to protect
the system against unauthorized access.
KAdditional information – The S153 register can be used to display the caller ID
of the remote station before the connection is established. The connection charges
can be reviewed during and after the connection. Information pertaining to the
establishment of the connection can also be returned (e.g. ALERTING).
KStatus displays – LED displays with two colors at the front of the ISDN terminal
adapter permit the monitoring of the ISDN connection and the line to facilitate
troubleshooting of possible system faults.
K24-hour access – is available to ELSA Support in the ELSA LocalWeb, the Internet
and ELSA's CompuServe forum.
KGuaranteed – 6-year warranty on the
ELSA TanGo 2000.
KProtected – The ELSA TanGo 2000 satisfies the CE requirements.
