9.1   Introduction Peripheral Equipment
The DCN system can be connected to various external devices including a telephone coupler.
9.1.1  Telos Digital Telephone Interface
The ‘TELOS’ digital telephone interface allows participation in a DCN conference without actually 
being present. The interface links the DCN system to the public telephone network. It enables a caller 
- such as one providing specialist advice or information to participate from a remote location - even 
overseas.
 The interface can be connected to the DCN system via the Central Control Unit LBB 3500/.. .            
A power supply unit provides power to the interface unit as well as providing the connection to a 
telephone or fax machine. For further information view the TELOS web-site at www.zephyr.com.
Interconnection
The telephone interface is connected to the line INPUT’ and line OUTPUT’ of the CCU. Use of the 
MIX-MINUS mode of the CCU is recommended (see 
). The telephone interface can also 
be used for ‘Remote interpretation’ in combination with the ‘Analog Audio Input/Output’ module     
LBB 3513/00 (Refer to the Instructions-for-use for the ‘Analog Audio Input/Output’ module code No. 
3922 988 92511).
