Wiring Changes
Below is the wiring definition for the 2-Wire Siemens Cordless System referencing both the
28VDC and 115VAC base units. The following items are found to be affected when
changing to the ePhone Cordless System with Bulkhead Cradle.
 The power connector type is different. The ePhone only comes in 28VDC using a
5A circuit breaker, this would impact the installation if the Siemens system was on a
power bus using a 2A circuit breaker. Additionally, if the Siemens Cordless System
installed used an 115VAC power supply then a power bus change will be required.
 The TELCO connector is different. The ePhone uses a 15 pin TELCO connector,
see wiring section for details.
 The cradle is provided with a pre-wired cable and connector for connection to the
base unit. The standard cable length is approximately 35”. Distances greater than
35” from the base unit would require an Extension Cable Connector Kit (PN
500480).

Information Bulletin
Below is the wiring definition for the ePhone Cordless System with Bulkhead Cradle.
 Power connection of 28 VDC aircraft power.
 The ePhone uses a 15 pin TELCO connector, see wiring section for details.
 The Bulkhead Cradle is pre-terminated, DB-9 male (40”). Distances greater than
40” from the ePhone Base Station would require an Extension Cable Connector Kit
(PN 962606).
 The Bulkhead Cradle requires approximately 2” of horizontal and vertical clearance
for removing the ePhone handset at the forward end of the cradle.
 ePhone range restriction include:
 Registration to the Base Station in an aircraft environment of approximately
100 feet
 Useable range in an aircraft environment of 50-80 feet
 The ePhone system requires configuration using a laptop in order to operate
correctly, access to the Base Station is required during setup. Reference the
ePhone System Installation and Operations Manual for further details.

System Interface and Configuration Details
The following examples depict the ePhone Cordless System with Bulkhead Cradle to an
Iridium system and CTU Connections. Contact ICG Technical Support for other interface
options.
Interface to ICS-220A
 ICS configuration should not change unless the user wishes to adjust the gain
settings.
 Wiring change only occurs on the Base Station side, reusing the 2-Wire connection
from the Satcom.
 The installer will need to connect a laptop to the Base Station via Ethernet cable and
configure the system for the correct 2-Wire extension (ex. Station 12).
 Required Configuration parameters when using the ePhone in 2-Wire Analog Mode.
Reference the ePhone Installation and Operations Manual for full details.
 Handset Registration
 Handset Names consistent with the connecting CTU
 Handset Extensions consistent with the connecting CTU
 Inbound Routing
 Outbound Routing
