IP400 Analog Trunk 16
• Analog Trunk Ports
These ports are used for connection to standard analog trunks (loop start or ground start). Using
standard structured wiring, these RJ45 ports can be extended to the required trunk sockets.
Trunk ports 1 and 2 are, in the event of power failure, automatically switched to PF1 and PF2
respectively on the rear of the unit.
• Expansion Port
Used to connect the Analog Trunk Expansion Module an Expansion Ports of an IP400 Office
platform.
• DC Power I/P Socket
Socket for the external 24V DC unregulated power supply (supplied with kit).
• Power Fail Trunks
These two ports must be set and connected to Loop Start trunks only. POTs plugged into these
two sockets are mapped to trunk ports 1 & 2 such that, in the event of a mains power failure, PF1
and PF2 can operate as 'hot lines' to the emergency services (eg. 911, etc).
• Protective Grounding Point
Within the USA a protective grounding must be permanently fitted. Connection of this protective
grounding requires the use of suitable tools and must be connected at both ends before
connection is made to the telecommunications network.
IP400 Analog Trunk 16 is supplied with one blue Expansion Interconnect cable.
