Globalstar GSP 2900 Voice and Data Fixed Phone

QUALCOMM Globalstar GSP-2900 Fixed Satellite Phones

The Globalstar GSP-2900 Fixed Satellite Phone offer innovative wireless solutions for quick and easy installation of communication systems in remote or hard-to-reach locations, as well as in under-served urban and rural areas.

For the first time ever, a Globalstar Fixed Phone can bring a dial tone to areas where traditional telephone services are not economically feasible. The Radio Antenna Unit (RAU) and Junction Box are mounted at a convenient outdoor location with a clear view of the sky and connect to a variety of available indoor telephone sets using standard telephone cable, thus providing satellite phone service from inside a building. Once installed, telephone sets connected to the fixed satellite phone system can be operated just like landline telephone sets.

Globalstar Residential Solutions
The Globalstar Fixed Satellite Phones enable remotely located residences to connect to the public telephone network through the Globalstar Communication System, using standard residential telephone equipment and wiring. Up to four standard telephone sets can be served by one Radio Antenna Unit (RAU) using one phone number.

Globalstar Business Solutions
Globalstar Fixed Satellite Phones allow standard PBX, key systems, and single business phones to be connected to the public telephone network using the Globalstar system.

GSP-2900 Fixed Satellite Phones Features:

  • Standard twisted pair subscriber analog phone connection.
  • Supports service of multiple extensions using standard telephone sets including wall, desk, and cordless models, and answering machines.
  • Supports standard dial tone, dial procedure, and call progress tones.
  • Globalstar access for incoming and outgoing calls.
  • Compatible with a variety of back-up power solutions, including solar power.

Enhanced Kit
The Globalstar Fixed Satellite Phone - Enhanced Kit (GSP-2900) consists of:
  • Radio Antenna Unit (RAU)
  • Junction Box
  • 12 VDC output/universal AC input power supply

The GSP-2900 Kits include:
  • 15 meters (50 feet) of power/telco cabling to connect the RAU and junction box.
  • A 12-volt power supply with 7m (21 ft.) of DC output cable. Two AC line cords are supplied, one with a European plug and one with a U.S. plug. Other country-specific AC line cords are available, upon request.
  • A backup battery for use with the QUALCOMM power supply. The backup battery offers 3.5 hours of talk and 24 hours of standby time in the event the AC mains fail.
  • Radio Antenna Unit (RAU).

The RAU is the Globalstar radio transceiver that enables communication over the Globalstar system. This electronics module houses the Globalstar radio, digital call processing circuitry and includes an integral mast antenna. It communicates with the Globalstar satellites using a CDMA air interface and connects to an analog telephone set using a twisted pair cable.

· Note: The RAU must be mounted in a position where it has a clear, unobstructed view of the sky.

· Junction Box
The Junction Box is the interface between the outside cables and the inside telephone wires. It provides the user and equipment with some protection against nearby lightning strikes when properly grounded. The junction box should be installed on the outside of the building or structure at the point where the indoor cables transition to the outside cabling.

Power Supply with Battery Backup

The Globalstar Power Supply with Battery Backup is a 12 VDC power source capable of supplying a minimum of 3 amps of current. The DC voltage, as measured at the RAU, should be in the range of 9.5 to 16 volts for correct product operation. The power cords shipped with the power supply are compatible with the AC wall outlets of most countries.

Battery Backup

A 12 volt, 4.5 AH sealed, rechargeable lead-acid battery provides backup for the power supply, in the event of AC mains failure. This battery backup provides approximately 3.5 hours of talk time or 24 hours of standby time. (These times may vary depending on how often you use the product, battery condition, ambient temperature, and other factors.) The battery should last 3 to 5 years under normal use.

Other Sources of Power

Other sources of power, such as solar, work well with the QUALCOMM Globalstar Fixed Satellite Phones, but are not sold by QUALCOMM. Contact Spirit Wireless to recommend a solution suitable for your location. The power supplied to the junction box and the RAU must be 12 volts, nominal. The DC voltage, as measured at the RAU, must be in the range of 9.5 to 16 volts.

Cabling

A 50 foot (15m), four wire telco/power cable is supplied with the GSP-2900 or may be purchased separately. This cable connects the RAU and Junction Box.

If necessary, you can manufacture the cable that connects the junction box and RAU. See Appendix B of the GSP-2900 Installation Guide for specifications. Note that any cable used for the QUALCOMM Globalstar Fixed Satellite Phones must meet these specifications.

Telephone Set

A telephone set is not included in the GSP-2900 QUALCOMM Globalstar Fixed Satellite Phone.

The telephone set you choose should be configured for tone dialing. A telephone set with a ringer equivalent number (REN) of less than five is recommended. A telephone set with a lower REN value will permit the user to place more telephone extensions on the line.

Making A Call

The Globalstar System Consists Of:
  • A satellite constellation in a 1414 kilometer orbit (878 miles) above the Earth.
  • Multiple ground stations called "Gateways".
  • The phones that communicate with the satellite (when in Globalstar mode).
The Globalstar system technology is designed to interface directly with a nation's existing phone system. This gives the service provider and/or the local government revenue from and control of its end of the satellite phone system.

Overview of a Globalstar Phone Call
1. A caller uses Globalstar mode to place a call via the satellite to one or more Gateways.
2. The Gateway routes the call to the existing phone network, in the case indicated below, a cellular Public Land Mobile Network (PLMN) network.
3. The PLMN routes the call to the intended receiver. The call is completed!
4. The call duration, service used, and service area are reported to the Service Provider for billing.
