monitoring station
The signaling occurs on the B-channel (X.75 connection)
and D-channel (X.31 connection).
The AT 2000 ISDN permits connection to multi-device and
equipment connections (PMP/PTP) and is connected in
front of telecommunications equipment and using a
Telekom junction box to the telephone line.
The AT 2000 ISDN can be activated via the serial S1
interface (optional) or the parallel S1 interface with 7 input
line inputs.
The outputs (relay) can be controlled depending on the
message line status (locally) and via remote control
according to VdS 2465 by reception and transmission
equipment.
In the event of tampering or damage to the relaying ISDN
line, the AT 2000 can send a message (tamper release).
The absolute operating procedure on the telephone line is
enabled by the blockade release.
Monitoring of the auto dialer and the telephone network
occurs through a routine call.
The AT 2000 has a tamper contact.
Audio and visual display.
Power monitoring: network, battery, undervoltage
The event storage for up to 512 events can be read out using
a PC.

Installation/Configuration Notes
ISDN connection
• The AT 2000 ISDN is suitable for connection to basic
access – with the international protocol DSS1.
• Primary multiplex connection S2M is not possible.
•
The AT 2000 ISDN communicator for danger alarms
must be connected to the S
0
bus as the first device.
With this connection, it is possible for the AT 2000 ISDN
to send a message even in the event of tampering or
damage to the bus wiring.
ISDN PTP
•
The "constant monitoring" layer 1 feature is present by
default for system access.
• The max. cable length from network termination NT via
the UAE 8/8 box to the TK system or to the end unit is
1000 m.
ISDN PMP
• The "constant monitoring" layer 1 feature is also
required with a multi-system connection.
•
The max. cable length between network termination
and TK system or end unit is 150 m.
ISDN X.31 transmission
•
Datex-P ISDN ACCESS 100 (X.31) "Access 100" service
packet for VdS 2465 (D-channel) enables the
configuration of a virtual dedicated line for tamper-
proof transmission. Additional D-channel services can
be used with this application after the AT 2000.
•
ACCESS ≥ 100 must be applied per MSN.
