R
For the RF-7800B-VU104, traveling from one spot beam to another, GPS information will be used to allow a
seamless spot beam transition, without the end user even knowing.
Finally, there are Universal Mobile Telecommunications System (UMTS) Subscriber Identification Module (USIM)
cards known as “Discreet SIM cards”, which do not provide specific coordinates of the BGAN terminal to the
BGAN Network. These USIM cards will only provide the Regional or Spot Beam Identification (ID) to the network.
Speak to your BGAN Service Provider for provisioning of these types of cards.
3.7.3 ISDN Voice Telephony Services
The Satellite Terminal provides an ISDN interface to connect devices for Circuit Switched voice and data services.
It is a Basic Rate (also known as 2B+D) interface and uses the European ISDN protocol. Service for only one 64
kbps B-channel is provided at a time.
The BGAN terminal has been successfully tested with the following ISDN handsets:
 ASCOM Eurit 33 plus
 SwissVoice Eurit 25
 Nera ISDN handsets (old Fleet and new WorldPro handsets)
 Siemens Gigaset SX255
 ISDN to Plain Old Telephone System (POTS) Converter, 12091-4160-01, using any 2-wire analog handset
Before the handset can accept incoming voice calls, program a Mobile Subscriber Number (MSN) using the same
number as programmed in the terminal (default is 1). Refer to Paragraph 4.3.1. This ensures that incoming voice
calls are directed to the handset. The handset's instruction manual will explain how to do this. Emergency calls can
be made without the correct MSN programmed into the handset.
3.7.3.1 Dialing
As the ISDN numbering system follows the same pattern as the normal telephone system, dialing is carried out in
exactly the same manner as making a normal telephone call. The subscriber number is used with the same
international and area codes as any other telephone network.
3.7.3.2 Multi-Subscriber Numbering (MSN)
ISDN supports MSN which allows more than one telephone number to be allocated to an ISDN line. The BGAN
Satellite Terminal assigns different MSNs for 4 k Voice, 3.1 kHz Audio, 64 k Unrestricted Digital Information (UDI)
and 56 k Restricted Digital Information (RDI) devices. Each incoming call will be directed to the appropriate MSN
depending on the type of call. This allows proper routing of incoming calls to the correct ISDN device (e.g. ISDN
phone, data card or Fax).
3.7.4 Data Services
The five types of Packet Switched data connections, known as Packet Data Protocol (PDP) Connections, consist of
a Background data service, and four Quality of Service (QoS) Streaming services.
Background Service: A Background connection shares the bandwidth of the satellite spot beam with all the other
active background connections in the spot beam, minus all the bandwidth allocated to streaming connections.
Background connections can reach up to 492 kbps for the RF-7800B-VU104, and up to 432 kbps for the RF-7800B-
DU024. For usage such as Email and Internet browsing, usually a Background connection operates at a higher data
rate and less cost than a Streaming connection. Background service rates are charged by the amount of MegaBytes
transferred across the network.
