2DCN design
2.1Introduction
The DCN Wireless has three parts: the wireless network, the DCN and the optical network. This chapter tells how to design the DCN.
2.2Calculation tool
The calculation tool makes the planning and design of the DCN easier. You can find the calculation tool on the
2.3Concepts
2.3.1Introduction
This section gives necessary data to understand the limitations in section 2.4.
2.3.2Trunk and tap-off sockets
The DCN uses two types of socket:
•DCN trunk sockets
Use the DCN trunk sockets to make a
•DCN tap-off sockets
Use the DCN
2.3.3Cables
Many devices used in the DCN have a 2 m cable. If necessary the extension cable (LBB4116) can extend the device cables.
2.4Limits
Make sure that these limits are not exceeded when you design the DCN:
Limit 1: Control capacity
The maximum number of active devices that the central control unit can control is 95:
•Max. 93x
•Max. 2x
•1x with intercom handset
•1x with ambient microphone
The number of passive devices is without limit (refer to section 2.5).
Limit 2: Power capacity
•The maximum power that one DCN socket of the central control unit can supply is 65 W.
•The total power that the DCN sockets of the central control unit can supply is 130 W.
•The maximum power that one DCN socket of the extension power supply can supply is 85 W
•The total power that the DCN sockets of the extension power supply can supply is 255 W.
Refer to section 2.6.
