l The bending radius of an E1/T1 cable must be at least three times its diameter.

l The bending radius of a signal cable must be at least five times its diameter.

Cable binding requirements

l Cables of the same type must be bound together.

l Different types of cables must be separately laid out and bound, with a minimum distanceof 30 mm (1.18 in.) from each other.

l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.

l The cable ties must face the same direction, and those at the same horizontal line must bein a straight line.

l The excess of the indoor cable ties is cut off. The excess of 5 mm (0.197 in.) of the outdoorcable ties is reserved, and the cut surfaces are smooth without sharp edges.

l After cables are installed, labels or nameplates must be attached to the cables at their ends,curves, and interconnection positions.

Security requirements

l When routing cables, avoid sharp objects, for example sharp edges on the wall. If necessary,use tubes to protect the cables.

l When routing cables, keep the cables away from heat sources and use heat insulationmaterials to insulate the cables from the heat sources.

l Reserve a proper distance (0.1 m or 3.937 in. is recommended) between equipment andcables especially at the cable curves to protect the cables and equipment.

Indoor cabling requirements

l Route each cable into the room through the feeder window.



31

l Reserve drip loops for all cables outside the feeder window before routing them into theroom. Ensure that the radiuses of the drip loops are greater than or equal to the minimumbending radiuses of the cables.

l When routing a cable into the room, ensure that a person is assisting you in the room.

l Apply waterproof treatment to the feeder window.

Outdoor Cabling Requirementsl Protect outdoor cables against potential damage. For example, put the cables through tubes.

l The cables to be protected include AC power cables, transmission cables, and cables laidout underground.

l When routing cables through tubes on the ground below the cabinet, put a 30 mm to 50mm (1.18 in. to 1.97 in.) length of the tubes into the base of the cabinet but do not put thetubes into the cabinet. Use waterproof tape or waterproof silicon gel to block both ends ofthe tubes and use sheet metal tabs to secure the tubes to the cable holes in the base.

l When routing cables through tubes along a metal cable trough below the cabinet, do notput the tubes into the base of the cabinet but cover the cable trough and connect the tubesto the cable holes in the base.

l Use clips to secure cables outdoors. For the method of installing a clip, see the installationguide delivered with the clip.

l Arrange cables neatly along the routing direction and use clips to secure the cables.

l Determine the positions where the clips are installed according to the actual situation. Forexample, 7/8" feeders are secured with clips at an interval of 1.5 m to 2 m (4.92 ft to 6.56ft), CPRI fiber optic cables and power cables are secured with clips at an interval of 1 mto 1.5 m (3.28 ft to 4.92 ft). Ensure that the clips are evenly spaced and in the same direction.

l When fastening cables with a clip, ensure that the cables are routed through the holes inthe clip and arranged neatly and straightly. Do not stretch the cables too tightly.

NOTE

There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows:
