Requirement for installation of

Satellite Base Station

In order to successfully install and maintain the switch in Remote Country we require the following information and facilities in Remote Country. Each section below lists either the required facilities or the required information needed for this installation.

1. Required environment in Remote Country

The location where the equipment is to be located should have the following features:

· Clean secure location for all indoor equipment. External secure housing may be required where the satellite platform is at a distance greater than 50 meters from the indoor power supply.

· Secure location for all outdoor equipment: The outdoor facility should either be securely walled or wire fenced against animal or human intrusion. Where wiring or security walling is provided minimum 250 cm inhibition and security spike wiring should be utilised.

· Secure location for all outdoor equipment: Where the Satellite dish diameter is larger than 2.5 meters a 10 meters perimeter clearance would be required. External secure power supply housing may be required where the satellite platform is at a distance greater than 50 meters from the indoor power units.

· Secure location for all outdoor equipment: where the equipment is placed close to public amenities and public line of site, adequate visual warnings must be provided in native language against intrusion and interference with high voltage facilities. PLEASE NOTE THAT UNDER INTERNATIONAL HEALTH AND SAFETY REQUIREMENTS A SUBSTANDARD INSTALLATION CANNOT BE AUTHORISED BY THE COMPANY.

· Internal temperature requirement – between 10 to 35 centigrade for all indoor units.

· External temperature requirement – between –12 to 50 centigrade for all outdoors units.

· 24 hour engineering access is required in an emergency.

· Local engineering expertise would be required in an emergency.

· Power protection should be available at the site, even though the equipment shall be provided with 30 minutes standby power.

2. Required hardware in Remote Country

What we need:

· Power supply for 110V or 240 Volts 50 Hz. supply.

· 19” Rack – this should be lockable and must be complete with the PDU (power distribution units) for 8 lines. The Rack required should be about 240 cm high.

· 1 dedicated analogue modem lines – this should be near the Rack and shall be used for remote management of the system

· Internet leased line – further specified below

· E1 interface lines – these are connected to the local PTT for inbound calls and call termination. The specification for these lines is further discussed below.

3. Location address of the site

The location of switch installation at the destination country will very much depend on the point of connection to the Internet line and the local PTT providing the E1 interface lines. Once the location of the switch for the remote country has been determined, the full address of location including Post-code (Zip Code) should be forwarded to CALLINGPLACES as soon as possible.

4. Internet connection In Remote Country

In order to be able to provide the service from Remote Country an Internet line is required. We would require at least one permanent 64k internet connection at the site where the platform is installed.

We would also require a list of companies providing Internet connection/IP bandwidth in Remote Country. The details of the Permanent IP connection, with contention ratio information, for the following bandwidth would be needed:

	64k
	128k
	256k
	512k
	1Meg

5. Requirement for the E1 - 30 line interface with local PTT

In order to receive inbound calls from the local PTT and terminate national calls, we would need interconnection via E1/T1 lines. There are several options on the interface lines and these vary from country to country. The physical connection on the lines should be 120 Ohm RJ45 (or if this is not available then 75 Ohm BNC pairs). We need the following data to be build on the E1 lines:

· Circuit to be set up as in/out circuits

· Circuit to be set up as hunt group of 30 channels. Each inbound call to be mapped to the hunt group in a cyclic order.

· 30 DDI numbers to be built on the hunt group. The DDI information to be passed as full string of digits.

· The CLI of the caller should be passed on to the circuits.

Once there is requirement for additional capacity, additional E1 lines can be added to the above configuration.

6. E1/T1 interface with local PTT

The information required for this interface are:

E1 or T1
R2 or/and SS7
If SS7 interface is used, then we need to know the particular type of SS7 signalling supported by the PTT. Also would require the common channel signalling preferences and set up supported by the local PTT.
What interface cables are supported by local PTT.
What is the make and model of the Network equipment connecting to by CALLINGPLACES

7. Capacity requirement for inbound and outbound termination traffic

What is the total number of minutes of terminating traffic which can be supported by the PTT switch?
What amount of minutes should CALLINGPLACES expect from the PTT switch?
The name, telephone and email address of the main technical contact for PTT installation?
The full address of the installation site and the details of the main site contact person?
The facilities provided at the installation site. The above sections contain the CALLINGPLACES requirements. We would require a list of facilities and services at the site, and consistency with documented requirements above to be provided to us in writing.
The level of technical support provided at the installation site. Are there 24 hours support at the site? Who can we contact in case of any problems?
It may be a requirement for CALLINGPLACES engineers to visit the site on regular basis. Who should they contact to arrange this?
It may be a requirement for at least one CALLINGPLACES engineer to be present at the site on a continuous 24 hour rotor. Who should we contact to arrange for permanent access?
