Phone Call Initiation

The radio is able to initiate phone calls to a Public Switched Telephone Network (PSTN) or Private
Automatic Branch Exchange (PABX) with duplex speech capability. This call type uses TETRA
individual call signaling using single stage dialing and hook setup for outgoing calls.
Using the hook signaling for phone calls, implies that until a traffic channel is allocated, the radio
generates all feedback tones internally. In addition, the radio accepts SwMI modification of the call
setup to direct, enabling the infrastructure to generate the progress tones.
Phone calls can also be made between TETRA radios using the Mobile Station International
Subscriber Directory Number (MSISDN) number as the called party number. MSISDN calls share the
same gateway as phone calls, that is, PSTN gateway configured in the codeplug. If an MSISDN call is
placed, two radios can have a simplex or duplex call based on the assigned ISDN number.
NOTICE: The Dimetra Infrastructure does not support private calls and Short Data Service
(SDS) through MSISDN.
2.9.2

Phone Call Reception

Incoming phone calls, from the land gateway to mobile, use on-off hook signaling. The radio extracts
the gateway ID from the call setup signaling, to determine whether to start phone or Private Automatic
Branch Exchange (PABX) call.
2.9.3

Call Restoration in Phone Call

If the radio roams while being in an active phone call, and the announced cell reselection is possible,
then the announced cell reselection is employed. Also the call restoration procedures are performed.
