Using A Telephone - Iridium ICHU1000 Operating Instructions Manual

Using a Telephone

To your Iridium equipment, you can connect a PSTN telephone or a
PBX. Many of the system's more advanced features, like the security
lock function, are however not accessible from a telephone. Neither
is any SIM card action. Therefore, when using the telephone, the
SIM card has to be operational. This means that the pin code has to
be disabled on the card, or the pin code must be entered from a CU
before the telephone is used. A CU is either a handset control unit or
a desk mounted control unit.
Telephone Call Syntax
For external calls, entering a telephone number on a PSTN
telephone follows the syntax of this example:
1. Pick up phone:
2. External call
3. Prefix for automatic call

6. Subscriber's number, e.g. 1 3 7 0 0 0

Factory setup of extension numbers are:
PSTN/PBX: 1000
CU 1: 1001
CU 2: 1002
CU 3: 1003
CU 4: 1004
Up to four control units and a telephone/PBX can be connected to
the transceiver at the same time. Note that if connecting a PBX to
the transceiver, the PBX must function as a PSTN telephone.
To dial control unit 1 from a local telephone connected to your Iridium
equipment via a PBX, first pick up the phone, then:
1. Dial the number for the outgoing line connected to the trans-
ceiver, eg.
2. When you hear the ready tone, dial the extension number of
control unit 1:
3. To confirm you want to make the call,
press
DTMF Tones - Limitations:
When used for internal calls, control units do not generate DTMF
tones. Therefore the PBX cannot be set up for using DTMF tones to
access extension numbers.
