ISDN Network Termination
Plug&Play installation
High quality and
ISDN services on
analogue ports available
The Product
Network Terminating Unit with two analogue ports for
the ISDN basic rate access
The NT1+2a/b is a network terminating unit with built-in
terminal adapter for ISDN basic connections. The system
realises the transition from the public ISDN network subscriber line to the private S-bus.
The digital interface allows the operation of ISDN systems,
telephones and PC cards. All services offered by the network
operator are thus available to the subscriber. Up to eight
ISDN terminals can be connected directly to the ISDN S-bus.
In addition, the terminal adapter also provides the interfaces
for conventional analogue terminals, such as telephones, fax
machines or answerphones.
For ISDN signaling, the NT1+2a/b provides two 64 kbps
bearer channels and a 16 kbps data channel (a signaling
channel which can also serve for data transmission). Two
simultaneous external calls are possible, as is channel bundling, the use of both bearer channels.
Advantages of the albis-elcon system
Benefits for the network operator:
 Use of latest IC technologies to enable increased functionality
 Cost-efficient multi-purpose equipment
 Reduced logistics costs due to compact design and lower
 High customer acceptance thanks to the „Two-in-onedevice“ concept
 Additional subscriber services
Benefits for the subscriber:
 Continued use of existing analogue terminals possible
 Use of ISDN service features on analogue terminals

ISDN Network Termination
Technical Data
ISDN features on the analogue ports (Selection of features, partly optional)
 CLIP (Calling Line Identification Presentation): the calling
subscriber´s telephone number is transmitted to the
called subscriber´s terminal
 CLIR (Calling Line Identification Restriction): transmission of one´s own number on outgoing calls is suppressed
 CF (Call Forwarding): calls can be forwarded unconditionally, on busy, or when there is no reply
 CW (Call Waiting): a waiting call is signaled during a
current phone conversation
 CH (Call Hold): calls can be put on hold
 AOC (Advice Of Charge): the cost of the call is indicated
on the phone´s display
 MCID (Malicious Call Identification): enables tracing of
bothersome callers
 Basic functions for setting up and clearing down calls
(call setup)
 Configuration and operation of the system are supported
by the service software
 Remote programming and/or configuration as well as
remote firmware update
 Reset to the default state (factory settings on delivery)
 Clearback Time Delay
Data Sheet | NT1+2a/b 2B1Q
 TP (Terminal Portability): terminals can be unplugged
from and plugged into the bus
 CCBS (Completion of Calls to Busy Subscriber): automatic callback on busy
 3PTY (Three Party Conference)
 ECT (Explicit Call Transfer): connection of the two external subscribers in a three-party conference, or of the
caller on hold with the current caller
Configuration options
The system can be optionally configured as:
 NT1+2a/b: S/T and both a/b-ports are available
 NT1 Standard-NT: i.e. only S/T-interface is available
 NT+2a/b: only the a/b-ports are available
Further functions
The emergency power supply can be provided either for one
of the three interfaces S/T, a/b1 and a/b2, or dynamically for
a/b1 or a/b2 (optional).
The S/T-interface can be configured as a passive bus or as
point-to-point connection.
To each a/b-port 1 - 3 multiple subscriber numbers (MSN)
can be assigned, having up to 20 digits per MSN.

ISDN Network Termination
Technical Data
Further functions
Each a/b-port can be configured for one of the three terminal
types: voice, G3-fax or multiport (e.g. modem).
Devices can be configured via the a/b-ports using DTMFsignalling or with help of the service software.
Service software
Service software for the remote or local configuration of the
NT1+2a/b is available as an option. This enables you to offer
your customers top-quality service and reduce your maintenance costs. The following functions can be realised remotely or locally:
 Device status inquiry and failure search
 Configuration of many internal settings
 Checking of various device interfaces as well as the device and software version
 Software download
 Loading and saving of a new NT1+2a/b configuration
