Calls from Mobiles
To initiate a call, the user dials the international call prefix 00
prior to the telephone number for the required destination.
The LES code is also included, either automatically when
using the default LES, or manually selected from the Display
Handset.
The mobile automatically includes information to identify the
MES and the particular end terminal that originates the call.
Saturn Bp Portable has six voice connections: the Display
Handset and five connectors (one internal and four external)
that are normally configured for standard telephone and a
telefax.
The LES uses the end terminal identifying information (OI)
for billing purposes.
The mobile transmits the dialling information on a channel
specially assigned by the NCS, to the LES, which also has
been instructed to tune to the same channel.
On receiving the call, LES routes it over the public telecom-
munications networks to the intended destination. When the
destination responds, for example by the dialled subscriber
lifting the handset, the call proceeds.
The illustration of the call initiation is simplified.

Access Request
When the MES originates a call it starts
by sending a request to the LES. This
initial request for service contains the
MES Return ID and type of service.
Saturn Bp incorporates a configuration
table for originating information,
accessible through the “Configure Ports”
function (70). This table contains one
entry for every physical connector with
the Originating Id and type of service for
that specific connector.
