Nortel Networks DCT1900 manual Area Coverage Test, Radio Coverage Verification

Technical Product Manual - DCT1900

Commissioning, Radio Coverage Verification

3.Move closer to each Base Station and check that the Portable Telephone locks to it (the DCA should display the correct Base Station number).

After having checked that all Base Stations are operational, proceed to the area coverage test.

4.3Area Coverage Test

The purpose of this test is to verify that the field strength is sufficient within the coverage area and that the Base Station delay values are correct. Sufficient field strength and proper Base Station delay values enable good speech quality everywhere within the covered area (rooms, elevator shafts, staircases). This test is executed with two Portable Telephones and requires two persons.

Test

1.Place the Portable Telephone in the DCA mode (refer to Section 7, "Maintenance" in this manual).

2.Call the other Portable Telephone.

3.One Portable Telephone user should now start moving around in the covered area.

4.Both users must check that a good speech quality is maintained everywhere. Pay special attention to areas such as edges of a building and areas behind metal structures where reduced speech quality is likely.

5.Mark areas where RQI is not stable on 20hex and where cracking sounds or mutes are heard.

4.4Radio Coverage Verification

This test procedure is in addition to 4.3, "Area Coverage Test."

Test
