Important Information Rleating to the Connection of this Equipment to the
Telephone Network
1
This equipment is approved for connection to the Public Switched
Telephone Network (PSTN) via direct exchange lines offering LD
(pulse) or MF (tone) dialling facilities.
Note: Although this equipment
can use either loop disconnect or DTMF signalling, only the perfor-
mance of the DTMF signalling is subject to regulatory requirements
for correct operation. It is therefore strongly recommended that the
equipment is set to use DTMF signalling for access to public or pri-
vate emergency services. DTMF signalling also provides faster call
set up.
2
During dialling, this equipment may tinkle the bells in other tele-
phones sharing the same line. This is not a fault and we advise you
not to call the Fault Repair Service.
3
It is strongly recommended that this equipment has the exclusive
use of a direct exchange line. This equipment is capable of auto-
matically answering an incoming call (see Section [44] of the Pro-
gramming Guide). If this feature is enabled and the system is
connected to a non-exclusive exchange line, the number of rings
before answering must be left at the maximum (15). Using setting
outside of the above will invalidate the approvals for this equipment.
4
Only the Network Operator, or a person authorised by the network
operator is allowed to make the connection from this apparatus to
the PSTN.
5
The approval of this equipment for connection to the PSTN is
INVAL-
IDATED
if the apparatus is subject to any modification in any mate-
rial way not authorised by BABT or is used with or connected to
internal software that has not been formally accepted by BABT. Use
with external control software or apparatus that causes the operation
of the integral modem or call setup equipment to contravene the
requirements of the standards for approval as designated.
All apparatus connected to this equipment and thereby connected
directly or indirectly to the PSTN must be approved in accordance
with Section 16 of the Telecommunications Act 1981.
6
It is important that the installer verifies the correct operation of stored
telephone numbers subsequent to their entry.
7
The connection to this equipment consist of:
Mains (AC) power
Excessive voltage circuit
Telephone line
TNV circuit
All other connections
SELV (Safety Extra-Low Voltage) circuits
This equipment is only to be installed and serviced by qualified per-
sonnel. The main cabinet contains circuits working at excessive
voltages (240VAC mains) and must be kept securely closed to pre-
vent unauthorised access. All connections to mains circuitry must
comply with current IEE regulations. This equipment is intended to
be supplied from a 220-250V 50Hz AC supply rated at 0.5A or
greater.
8
This equipment is not suitable for use as an extension to a pay-
phone.
9
This equipment has been approved for the use of the following features:
Auto Dialling
Auto Answering
Repeat Attempt Dialling
Tone Detection
Series Connection Facility
Modem Facility
Alarm Dialling and Signalling Facility
Any other usage will invalidate the approval of this apparatus if as a
result it then ceases to comply with the standards against which
approval was granted.
10
Series Connection (“line interrupt”). This equipment has been
approved for series connection. The equipment will induce a 12mV
drop at 40mA in the loop connection between the main apparatus
(e.g. a telephone) and the PSTN.
If the equipment connected in series with this apparatus requires a
shunt wire (3 wire connection), it will be necessary for the installer to
make this connection within the control panel. Refer to Connection
Details for more information.
Only one series apparatus may be connected between the PSTN
and the main apparatus (e.g. a telephone).
11
All connections to the PSTN must be via 0.4 - 0.6mm solid copper
core conductors suitable for connection to 2.8mm diameter screw
terminals. Standard core cable is not acceptable.
12
Due to the lack of echo suppression tone, this apparatus may not be
suitable for dialling international calls.
13
The definition of a Relevant Branch System (RBS) can be found in
BS6789 Section 6.1:1986 Clause 2.4.
14
This apparatus has not been designed for use with a PABX/Switch-
board.
