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'

'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.
