Umts installation

Cables should be straight and ordered, not cross each other. Their skin should not be damaged. If necessary, reserve additional length for the cables.

Every label should be affixed 2 cm away from one end of the cable. Label indicates the destinations of both ends: cabinet number plus slot number plus socket number. Remove the hole cap, lay the cables, cut the appropriate holes with side cuts to pass the cables and reinstall the cap in the engineering hole. Installation Procedure Do not pull the optical fiber cable from the inner side of the coil because the cable may get tangled.

If the cable is tangled, carefully Carefully release the untangle it and optical fiber cable coil make sure the after coil while is bending radius is gently pulled up the at least mm. To pass trough enginnering passtrough holes, two operators should cooperate at the two sides of the wall to thread the optical fiber cables through holes in the wall or feeder outlets smoothly: one pulls the cable and the other releases the cable coil after coil so that the cable will not get tangled.

Do not pull cable from the connectors. Do not bundle the optical cable too tightly. Otherwise, optical loss will be increased. Please unplug the LC thumb and the carefully distinguish the forefinger, and insert the connector. They can have a slight curvature. Step 2: Gently insert the inner sleeve into the optical port. Otherwise, redo Step 2. Keep the optical fiber cables from sharp Correct operation: The edges and make sure optical cable should be placed along the outer the bending radius is at side of the E1 cable so least 40 times of the that its bending radius cable external diameter.

Checking Installation n Cabinet installation location complies with the engineering design. If paint is lost, cabinet must be repainted with adequate paint for outdoor use, in the same color of the cabinet. The flat washers or spring washers are in place. Strap ties are evenly distributed, neither tight nor loose. There should be no cable clips or sundries left at the installation site. The hoisting operation is prohibited in windy, snowy, or rainy days.

Take out the cabinet, make its fixing board upwards, and lay it on the floor 2. Bind the fixing board with rope. Two persons stand at the foot of the tower. Install pole anchor clamp components. Screw down M10 bolts tightly.

Antenna Installation Parameters n Height The installation height of antenna on the tower is determined by network planning design. If two antennas in same sector, must share the same azimuth.

Lighting rod 3. Antenna 2. Default is 0. The effect of the rear and side lobes are critical when deploying UMTS networks. It is estimated an effective range of 50 cm to the back and back sides of the antenna. The basic installation consists of inserting a SIM card, entering the PIN code and connecting the existing analogue line device to the appropriate port on the gateway.
