STATUTORY NOTICES
Case Communications Ltd. declare that this product conforms with the requirements of the European
Communities Council Directive of 73/23/EEC on the harmonisation of the laws of Member States to electrical
equipment designed for use within certain voltage limits.
Case Communications Ltd declare that this product conforms with the protection requirements ofCouncil
Directive 89/336/EEC on the approximation of the laws ofthe member states relating toelectromagnetic
protection.
This equipment has been tested using shielded cables supplied by Case Communications Ltd. These cables, or
equivalents, must be used to ensure compliance with this declaration.
All PCB assemblies contain Electrostatic Sensitive Devices (ESDs) which may be permanently damaged if
incorrectly handled. This equipment must be handled in accordance with BS5783 code of practice for the
handling of electrostatic sensitive devices.
The System Control Board DT300 contains a Nickel-Cadmium (NiCad) battery which contains toxic
substances. The following instructions must be followed when handling or disposing:
(i) Non-conductive anti-static bags must be used for transportation and storage of the board
assembly.
(ii) Care must be taken not to short-circuit the battery.
(iii) The battery must not be disposed of on an open fire.
The earth stud on the rear of the equipment must be connected to earth.
The mains powered power shelf must be connected to earth via the power lead. Protective covers on this
unit should only be removed by authorised personnel.
The DC powered power shelves must be connected to earth via the marked earth terminal.
The 3400 and 3800 must not be transported with the power supply units fitted to the chassis since this can
cause dislocation of the card guides if the unit is subjected to impact

STATUTORY NOTICES
APPROVAL
The approval number for the 3200 multiplexer is NS/3660/12/H/452538.
The 3200 equipment is approved for indirect connection to the PSN via the 4 wire E&M (SSDC5) PABX tie line
ports and G.703 2048 kbit/s PABX ports and for direct connection to G.703 2048kbit/s and X.21 Nx64kbit/s
'Private circuits' subject to the following conditions:-
1)WARNING. Interconnection directly, or by way of other apparatus, of ports marked:-
'WARNING. Connect only apparatus complying with BS6301 to this port'
or
'WARNING. Connect only apparatus complying with BS6301 to these ports'
with ports not so marked may produce hazardous conditions on the network. Advice should be obtained from
a competent engineer before such a connection is made.
2)All ports are marked as shown in para 1, and other than those connected to Public Telecommunication
Networks, may only have equipment complying with BS6301 connected to them.
3)Connection of power supply. This apparatus may only be used with Type 3000 power supply equipment.
Other usage will invalidate any approval given to this apparatus if as a result it ceases to comply with
BS6301:1982.
4)The primary DC power source for the equipment must be from a power supply complying with BS6301.
5)For voice frequency circuits the total power to line level must not exceed -13dBm.
6)Voice frequency circuits provided on channel interface cards DTE90 to DTE95 and DT515 may be indirectly
connected via the isolation barrier DT290 to the PSTN or 'Leased lines'. This connection must be made in
accordance with the instructions contained in the relevant operators manual for these cards.
7)Direct connections may only be made to NTTP ports from 2048 kbit/s PCM interfaces utilising the Dual Line
Interface card DT310. The Dual V.11 Card DTE50 and the Dual Nx64k Card DT585, may be directly
connected to 'Private circuits'.
8)Prevention of access by user. If a Ringing Generator is fitted in the chassis or an external ringing supply is
connected or 2Wire Loop Disconnect cards are fitted, the following applies: This apparatus is intended to be
accessible only to authorised personnel. This apparatus must be installed in a locked room or similar
environment. Failure to prevent such user access will invalidate any approval given to this apparatus.
SAFETY
All interface ports in the multiplexer have a safety status of 'TNV' when a DT579, DTE063 or a DTE064 is
installed, or an external ringing supply is connected. In all other configurations the interface ports have a
safety status of 'SELV' This must be taken into account when connecting the equipment.
For Mains powered multiplexers, the socket outlet supplying this equipment shall be installed near the
equipment and shall be easily accessible.
