Installation Manual iSiteC ODU3601C CDMA Soft Base Station Safety Precautions　S-5 l Installation of AC power supply equipment must be implemented in compliance with local safety regulations, and the personnel engaged in AC power supply must be qualified for high-voltage and AC operations. l Electrical conductors such as watches, bracelets and rings must be removed before operation. l If the cabinet is found to be wet, please turn off power supply immediately. l Keep the equipment dry upon operation under humid environment. Warning: Improper high-voltage operations may result in fire accidents and electric shocks. Therefore, AC power cables must be laid in compliance with local codes and regulations. High-voltage operators should be trained and qualified. 3.2 Power Cables Caution: Live installation and removal of power cables are prohibited. Electric sparks or arcs may be generated when power cables get in touch with conductors, which may cause fire accidents or eye injuries. l Power must be switched off before installation and removal of the power cable. l Before connecting a cable, make sure that the cable and cable label to be used should match actual installation requirements. 3.3 Tools Warning: High-voltage and AC operations require special tools instead of general-purpose or makeshift tools.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Safety Precautions　S-6 3.4 Drilling Warning: Unauthorized drilling on the cabinet is strictly prohibited. Improper drilling may damage the connections and cables inside the cabinet and the metal filings produced during the drilling may cause short-circuits of the circuit boards if they fall into the cabinet. l Wear protective insulation gloves and remove the cables inside the cabinet before drilling holes on the cabinet. l Take care of your eyes when drilling holes. As the splashing metal burrs &scraps may hurt your eyes. l Prevent metal scraps from entering the cabinet inside. l Improper drilling will damage the electromagnetic shielding performance of the cabinet. l Clean up the metal scraps after drilling. 3.5 Thunderstorms Danger: High-voltage and AC operations and operations on the steel towers and masts are strictly prohibited in a stormy weather. l Thunderstorms can generate powerful electromagnetic field in the atmosphere. Therefore, equipment should be grounded properly in order to prevent the equipment from being thunderstruck. 3.6 Static Electricity Caution: Static electricity generated by the human body may damage the electrostatic-sensitive parts on the circuit boards, such as large-scale integrated circuit (IC). l The grating generated between human activities and the components is the rootage for electrostatic charge accumulation. In dry climate, the electrostatic
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Safety Precautions　S-7 charge carried by human body may go up to 30 kV, which will remain on the human body for a rather long period of time. The operator’s contact with the sensitive component and the resultant electric discharge will cause damage to the component. l Before contacting/touching any equipment such as holding plug-in boards, circuit boards and IC chips, put on the anti-static wrist strap with one end well grounded so as to prevent sensitive parts from getting damaged by static electricity on the human body. l Before operators touch the board or module, they should release the electrostatic charge in their body. That is, before the operator touches a board or a module, he or she must wear the anti-static grounded wrist strap. The connecting line between the wrist and the grounding point should connect in series with a resistance greater than 1 M¦¸ to protect people from being accidentally shocked. The resistance value greater than 1 M, is rather low in terms of electrostatic voltage discharging. The anti-static wrist strap should be checked regularly. Using other cable to replace the cable of anti-static wrist strap is strictly prohibited. l Electrostatic-sensitive board or module should not be in contact with the object with static electricity or the object that may easily generate static electricity. For instance, packaging bags, delivery boxes and conveyor belts made of insulating materials will generate static electricity by themselves, and can cause electrostatic charging when in contact with human body or the earth and might thus bring forth damages. l Electrostatic-sensitive boards or modules can only contact quality discharging materials, such as anti-static packing bags. The board in stock or in the course of transportation should be packaged with anti-static packing bag. l Before the measurement device is connected to boards or modules, first discharge its static electricity, that is, the measurement device should be grounded first. l The single board or module should not be placed near strong DC magnetic field, for instance, near the cathode ray tube of the oscilloscope. The safety distance should be at least 10 cm. l Damage caused by static electricity is accumulative. If the damage is slight, the component will not malfunction. However, as the number of damages increase, the components may suddenly fail. The electrostatic discharging damage to the component is of two types: obvious damage and hidden damage. Hidden damage is not shown when the damage occurs, whereas the component may become vulnerable and easily get damaged under the condition of over-voltage and of high-temperature. The correct way of wearing anti-static wrist strap is shown in Figure 1.

Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-6 2.2.2 Example of Indoor Plinth Installation Inside the equipment room, if ODU3601C cannot be installed on the wall (e.g. structure pole, hollow wall body, clapboard wall in the simplified equipment room), it can be installed on the plinth. The position of the plinth should be as close to the wall as possible. Figure 2-4 shows the indoor plinth installation of ODU3601C with IAFB. 1) Front view 2) Side view 3) ODU3601C 4) IAFB 5) Indoor grounding bar 6) Support 7) Feeder window 8) Jumper 9) Protection grounding 10) ODU3601C PGND cable 11) IAFB grounding bar 12) Power cable 13) GPS feeder 14) Wall Figure 2-4 Installing ODU3601C on the plinth 2.2.3 Example of Concrete Pole Installation This installation mode applies to such environment as fields, villages, towns, road sides, etc. to cover the locations like villages and towns. In this case, two poles must be used in the installation no matter that the ODU3601C to be installed is an omni BTS or a directional one. I. Facility requirements l The standard spacing between two poles should be 5m (not less than 3.5m at least), and horizontal diversity distance between two antennae should be 6m (not
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-7 less than 5m at least). For an omni BTS, a metal mast should be used to meet the requirements for horizontal diversity between two antennae. For a directional BTS, only a dual polarization antenna is required and the spacing between two poles should be determined for the convenience of platform establishment. l If the platform is established 3m above the ground, for an O(1) BTS, the platform should be strong enough to bear the load over 500kg; for an S(1/1/1) BTS, the platform is required to bear the load over 1500kg. l Between two poles, two or more metal fixing beams should be installed. And at the joints between beams and poles, the beams should be welded reliably with the down leads of pole lightning arresters. Dot welding is not allowed. It is recommended to install a metal fixing beam respectively on the platform and at the place 2m above the platform. And install two (according to the type of BTS) 2m metal holding supports between two beams by soldering so as to bear the ODU3601C and other equipment. The diameter of each holding support is 60mm~114mm, and the spacing between them is 80cm. l Install a vertical cabling ladder (300mm wide) via the metal fixing beam between two poles. The lower end of the ladder should be 1.2m away from the platform. Connect the fixing beams, on which the cabling ladder is fixed, to the flat steel (for lightning protection and grounding) by soldering. Dot welding is not allowed. l The antenna support is made of steel pipe with the diameter 60mm~114mm. The omni antenna should be 1m away from the antenna support horizontally. In the case of a directional antenna, its holding support may remain unextended. II. Layout Figure 2-5 shows the installation of ODU3601C by two concrete poles.

Note l To facilitate the introduction of power cables and trunk cables, first determine the metal holding support on which the ODU3601C is to be installed. IAFB or AC lightning protection box can be installed below the ODU3601C. The IABB can be fixed on the platform directly. If more than 2 battery boxes are needed, a platform should be established below the platform. l Equipment like the ODU3601C, IAFB, UPS, etc. should be installed between two poles via metal parts. It is not allowed to directly install them on poles. l When feeders are used, the antenna jumpers should be bound on the crosspieces of poles via cable ties. For the convenience of feeder connector preparation and maintenance, it is prohibited to lay feeders transversely. The feeders should be routed along the sides of the cabling rack. l If the poles are not long enough, it is recommended to connect the antenna and the ODU3601C via jumper. And the jumper should be bound at the sides of the cabling rack and on the crosspieces of poles via cable ties. Both ends of the jumper should be grounded. l Lightning arresters should be respectively installed on two poles, and the antenna of the ODU3601C should be in the protection range of the two arresters (pitch

The 40mm%4mm hot-gavanlizing flat steel should be used as the downleads of arresters. l The external shielding layer of the ODU3601C antenna and feeder should be grounded at the bottom of the antenna and at the front end beofore they are connected to the ODU3601C. The grounding cable should be connected to the cabling ladder or other metal grounding parts. The grounding cable should be made of yellow-green (or black) plastic insulation copper wire with the core diameter not less than 6mm2. l Grounding bar can be installed on the metal holding support, or fixing beam, or platform directly and reliable electric connection should be achieved among the grounding bar and the metal parts aforementioned. A dedicated grounding downlead should be installed on the grounding bar and be connected to the counterpoise. l Power cables and trunk cables should not be winded or bound on the arresters or their downleads, instead, these cables should be kept as far as possible from the downleads of arresters. Power cables and signal cables should be distributed horizontally and the spacing between any two cables should be at least 5cm. And they should not be routed vertically and crossly. 2.2.4 Example of Metal Mast Installation on Building-top Such installation of ODU3601C is applied for the coverage of villages and towns. I. Facility requirements l For an omni BTS, 3 masts should be used (one is used to install the lightning arrester and the other two to install two monopole omni antennae. The spacing between the latter two masts should be over 4.5m. Two masts are generally used for a directional BTS, as dual polarization antenna is adopted for the BTS. l The length of the mast should be determined by the height of the ODU3601C antenna. However, based on the conditions on building-top, the mast length should not be more than 8m. l The mast should be made of steel pipe with sufficient intensity and the dialmeter from 60mm to 114mm. Each mast must be secured by three steep ropes at least. l A cabling rack should be installed between the masts on which the antenna is fixed. Its height should be lower than 1.2m. l The PGND bar should be fixed to the AC lightning protection box or at the bottom of the IAFB mast and close to the building wall. Following are three methods to connect the PGND cables: a) If the equipment room is located in the building, lead the grounding cable from the building-top to the grounding bar in the equipment room; b) Connect the grounding cable to the counterpoise at the building bottom;

Note l For antenna jumper and feeder routed vertically, bind them on the metal masts with the spacing of 30cm via black cable ties; for antenna feeder routed along the cabling rack, fix them with the spacing of 1m or 2m via feeder clips. l Power cables from ODU3601C to ODU3601C should be protected by metal tubes, and fibers for cascading by currgated tube. Power cables and fibers routed vertically should be bound on the metal masts via black cable ties, and those routed horizontally should be bound to the cabling rack. l Power cables should be distributed along the outer side of the cabling rack, and far away from the fibers and feeders. 2.2.5 Example of Tower Installation This mode applies to such locations as fields, villages, towns, and roadsides to cover villages, roads, etc. In this mode, the hoisting of ODU3601C is involved.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-12 Caution: When hoisting the ODU3601C, try to avoid any collision between ODU3601C and the tower. I. Layout of tower installation The tower installation features in simple operation, lower cost and small installation area. Such installation applies to the coverage of roads and the case that the antenna needs to be installed over 15m in height. 1) Facility requirements l The support on which the directional antenna is installed should be extended out of the platform for at least 0.5m. Proper support length of the omni antenna should be determined to meet the requirements for the horizontal diversity distance (over 4.5m) between two antennae. l The diameter of the holding support on which the antenna is installed should be 60mm~114mm. The length (generally, omni antenna: 1m; directional antenna: 3m) of it should be determined according to the antenna type and sizes. l A square platform(3m % 3m) should be established 3m above the ground with the bearer capability more than 500kg. And a sun-shading shed should be established 3m above the platform. l A 2m holding support should be fixed to the tower body vertically above the platform so as to install ODU3601C,Lightning arrester, etc. The number of supports is determined by the number of ODU3601Cs, and the diameter of each support should be 60mm~114mm. 2) Installation layout Figure 2-8 shows the layout of ODU3601C installation on tower.

And all feeders should be fixed via feeder dual-clips. l Install AC lightning protection box and grounding busbar on one support, and the ODU3601C on the other. If the ODU3601C is cascaded with other ODU3601Cs, install them on other supports. l Install PGND bar on the tower directly. And its location should be close (the PGND cable length should not be more than 1m) to AC lightning protection box. It should have its dedicated grounding downlead (made of 40mm % 4mm hot-gavanlizing flat steel). PGND bar and its downlead should be connected via 35mm2 yellow-green plastic insulation copper wire or welded directly. Neither the bar nor the downlead should be insulated from the tower body. l The external shielding layer of ODU3601C coaxial feeder should be grounded on tower top and grounded before the feeder is connected to the ODU3601C. The grounding cable should be connected to the tower body. The grounding cable should be made of yellow-green (or black) plastic insulation copper wire with the core diameter not less than 6mm2. l Power cables and signal cables of ODU3601C should not be winded or bound on the tower. They should be cabled as horizontally as possible.

After the drilling, remove the dust inside and outside the holes with a vacuum cleaner, and then check the distance among the holes. Whenever big errors occur, the relevant holes must be relocated and drilled again. Caution: 1) Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it in the right direction, as vibrations may lead to damaged floor and the hole not straight. 2) The hole depth should be the length of the expansion bolt sleeve plus the drill bit. The hole depths of respective holes should be consistent. Before measuring the hole depth, remove the dust inside the hole and measure the hole depth. Remove the dust with a vacuum cleaner before drilling. 3) If the floor is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the hole. 4) Unfix the spring washer, nut and plain washer. Put the expansion bolt into the hole and knock directly on the bolt with a hammer (such as nail hammer) until the bolt is completely driven into the floor. Then, put the nut on the bolt and tighten it until the bolt is expanded slightly so as to avoid it getting loose.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-43 Caution: The proper length of the hole should be 55mm~65mm. Otherwise, the expansion bolt cannot be completely driven into the hole, which affects the reliability of the box. 5) Put in turn spring washers, and plain washers onto 4 M12%60 bolts, and pull 4 bolts through the holes at the bottom of the support, then put expansion sleeves and nuts onto the bolts. And then put the bolts into the holes made on the concrete floor and tighten the bolts with a spanner, as shown in Figure 2-43.

Put washers and nuts onto the bolt, and tighten the nuts reliably with a spanner. 6) Method to install the sun-shading cover is the same as that mentioned in "Installing the box on concrete floor". 2.5 Installing Cables During the installation of ODU3601C major equipment, the cables (excluding feeders) at the ODU3601C side have been distributed. Following is to introduce the cable connections between major equipment and auxiliary equipment, and those among auxiliary equipment in terms of varied networking modes. The installation of feeders is covered in Chapter 3.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-48 2.5.1 Cable Connection Requirements I. For power cables 1) Gists for indoor installation l Power cables should not be cross-connected or in parallel with signal cables. l Cables distributed on the wall must be protected by PVC cabling trough, which should be fixed on the wall with wall fixing clips. And cables should be distributed horizontally and straight. Even if turns are unavoidable, the minimum angle at each turn should not be smaller than 120°. l Power cables should be labeled after the connection. For the appearance and contents of the power cable label, refer to "Appendix F Engineering Labels for Cables ". 2) Gists for outdoor installation l It is strongly prohibited to tie AC power cable on the iron objects and then lead it into ODU3601C. Instead, the cable should be first connected to porcelain insulator, then to ODU3601C. l Power cables distributed along the iron object and pole must be protected by currgated tubes, as well as the transmission cables. The tubes should be fixed with black ties. Cables should be distributed as horizontally and straight as possible. If turns of cables are unavoidable, the turns should be be made smoothly via circular arcs. II. For grounding cables As the requirements for grounding cable connections are comparatively complicated. Following is to describe them in terms of varied installation modes. 1) Installing ODU3601C on tower l The grounding of ODU3601C system and tower lightning protection system must share the same grounding body. l When the ODU3601C is close to the transformer for power distribution (straight distance less than 30m), the counterpoise of the ODU3601C system should be connected to that of the transformer and form a unified counterpoise. l When an independent grounding busbar is adopted for the ODU3601C, it should be installed on the tower directly without any insulation processing. The grounding busbar of the ODU3601C should have the dedicated grounding downlead made of 40%4mm hot-gavanlizing flat steel. The PGND bar should be connected or welded to the grounding downlead via 35mm2 yellow-green plastic insulation copper core wire. The downlead should not be insulated from the tower body. 2) Installing ODU3601C on poles l The PGND of ODU3601C system should share the same grounding body with the lightning protection grounding of poles.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-49 l When the ODU3601C is close to the transformer for power distribution (straight distance less than 30m), the counterpoise of the ODU3601C system should be connected to that of the transformer so as to form a unified counterpoise. l The overlapped parts of the metal fixing beam (between the two poles) and the downlead of the lightning arrester should be soldered together reliably. Various equipment is installed on the metal holding support between fixing beams (the support is soldered on the beams). The mechnical parts of all equipment should contact the metal holding support directly without any insulation processing. Full-length welding should be adopted here, instead of dot welding, as the latter is unreliable. l The overlapped parts between the metal fixing parts of the platform and the downleads of the two lightning arresters should be reliably welded together. Or, instead, a 40%4mm hot-galvanizing flat steel should be installed on the platform. The two ends of the steel should be welded to the bench and the middle part of the steel to the downleads of arresters. If the platform and the downleads of arresters have not be welded together when the concrete pole is set up, connect them via 35mm2 yellow-green protection grounding cable and the grounding clip that connects the flat steel to the OT. Full-length welding should be adopted here, instead of dot welding, as the latter is unreliable. l Cabling ladder should be installed and fixed via metal fixing beam between two poles for antenna feeders. Good electric connection should be achieved between the cabling ladder and the fixing beam. Meanwhile, the overlapped parts of the fixing beam and the downlead of the lightning arrester should be welded together. l ODU3601C grounding busbar should be installed directly on metal holding support or platform without any insulation processing. A dedicated grounding downlead (made of 40%4mm hot-galvanizing flat steel) should be prepared for the grounding busbar. ODU3601C grounding busbar should be connected to the grounding downlead via 35mm2 yellow-green plastic insulation copper wire or be welded with it. And the downlead should not be insulated from various metal parts between the two poles. l Installing ODU3601C on metal mast of building-top l The PGND of ODU3601C system should share the same grounding body with the lightning protection grounding of the metal mast on building-top. l If the building containing the ODU3601C is close (straight distance less than 30m) to the transformer for power distribution, the counterpoise of the building should be connected to that of the transformer and form a unified counterpoise. l ODU3601C grounding busbar should be installed together with the ODU3601C directly on the metal mast without any insulation processing. At the same time, a grounding cable should be led from the metal mast to the ODU3601C grounding busbar, be fixed via bolts or be welded onto the metal mast. It should be made of yellow-green plastic insulation copper wire with the core diameter not less than 16mm2. Or, instead, a piece of 40%4mm hot-galvanizing flat steel should be
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-50 welded onto the mast and the wire hole should be reserved on the other end of the steel, so as to connect grounding cable to the ODU3601C grounding busbar. l If grounding bar or grounding point is available in the building-top or inside the building (e.g. the PGND bar of the communication euipment room), the downlead of the ODU3601C grounding busbar should be connected directly to the grounding bar available on building-top or inside the building. The grounding downlead should be made of yellow-green plastic insulation copper wire with the core diameter not less than 35mm2. l If no grounding point is available inside the building, the downlead of the ODU3601C grounding busbar should be led down to the building bottom and connected to the counterpoise of the building. The downlead should be made of 40%4mm hot-galvanizing flat steel or yellow-green plastic insulation copper wire with the core diameter not less than 35mm2. 3) Installing ODU3601C indoors l If the equipment room is close (straight distance less than 30m) to the transformer for power distribution, the counterpoise of the equipment room should be connected to that of the transformer so as to form a unified counterpoise. l If PGND bar is available inside the equipment room, the grounding busbar of the ODU3601C system should be connected via PGND cable to the grounding bar of the equipment room directly. The grounding cable should be made of 35mm2 yellow-green plastic insulation copper wire. l If PGND bar is available in other rooms (e.g. communication equipment room in the building) instead of the equipment room, the downlead of the ODU3601C grounding busbar should be connected to the grounding bar in such room. The grounding downlead should be made of yellow-green plastic insulation copper wire with the core diameter not less than 35mm2. If no groundign point is available in the whole building, the downlead may be led down to the bottom of the building then to the counterpoise of the building. The grounding downlead should be made of yellow-green plastic insulation copper wire with the core diameter not less than 35mm2. 2.5.2 Networking of AC Lightning Protection Box I. Plan without the IABB Figure 2-48 shows the connection between the ODU3601C and an independent AC lightning protection box.

All boxes mentioned in the chapter are of 20kA. Three cables are used for the external connection of the AC lightning protection box: 1) External power supply input cable It is a twin-core cable (L, N). When AC power is led into the box via this cable, the live wire is connected to the "L" end and the neutral wire to the "N" end. The cable is provided by user and the ends of the cable can be distinguished via a multimeter, i.e. the one with lower voltage is "N" end, and the higher one is "L" end. 2) Cable connecting the box to the ODU3601C It is a complete three-core cable (L, N, and PE). The port at ODU3601C side is a round waterproof connector which has been installed during the instllation of major equipment. The output interface of the lightning protection box is an air switch. When connecting this cable, directly take off the cover of the cable and insert the copper-core wire into the switch. In terms of its appearance, if the cable comprises three wires, black one, white one and yellow-green one, the black is L end, the white is N end, and the last one is PGND wire. If it is made of coffee, blue, and yellow-green wires, the coffee wire is the L, the blue wire is the N, and the last one is PGND wire. Figure 2-49 shows the connection.

If the AC power cable carries PGND cable (PE wire), the PGND cable should be grounded together with the PGND of the ODU3601C system. The PE wire should be connected directly to the grounding bar of the box. AC lightning protection box should have a PGND, and the PGND cable should be made of yellow-green plastic insulation copper wire with the core diameter not less than 16mm2. The length of the PGND cable connecting to the ODU3601C grounding busbar should be less than 1m. Caution: 1) Generally, the only power cable provided by Huawei together with the ODU3601C is 3m. Users are required to prepare the extra cable if it is not long enough. 2) The external AC power cable to the ODU3601C should be connected to the AC lightning protection box. It is not allowed to connect the external power cable to the terminal for power distribution in the IAFB first, then to the AC lightning protection box. 3) Above principles for cable connection are also applicable to the IAFB (with AC lightning protection box built-in). II. Plan with the IABB Figure 2-50 shows the connection in this networking mode.

Following is to describe the cable connection between the IABB and the ODU3601C. 1) Cable connection between IABB and ODU3601C Two cables are led out from the IABB. One is of +24V and red, and the other is of GND and black. Two cables are connected to the DC power cable of the ODU3601C through a commutator. The +24V cable is interconnected to the red one of the ODU3601C DC power cable through the red plug of the connector; and the black GND cable is interconnected to the black one of the ODU3601C power cable through the black pulg of the commutator. After their interconnections, two types of tapes should be used for the waterproof of the connections. The detailed processing is available in Section 2.3.6. 2) Grounding of the IABB The battery box is generally installed on the platform. In this case, the metal shell of the box should be grounded, and the PGND wire should be connected to the ODU3601C grounding busbar from the PGND terminal. The wire should be made of yellow-green plastic insulation copper wire with the core diameter not less than 16mm2. The batteries inside the box should not be grounded. 2.5.3 Networking of IAFB I. Plan with backup power supply equipment Figure 2-51 shows the connection between the IAFB and the ODU3601C in the ODU3601C networking (without UPS and the IABB).

One IAFB can supply power for up to 3 ODU3601Cs at the same time. Please connect the relevant cables correctly according to the labels on them, the correspondence shown in Figure 2-52 and Figure 2-53, and the correspondence between labels and cables shown in Table 2-3. & Note: 1) Figure 2-53 shows the front view of cable connection on DDF shown in Figure 2-52. 2) The PGND cables of ODU3601C and other equipment in the system should all be connected to the grounding bar on the shell of the IAFB. And a PGND cable should be led from the grounding bar on the IAFB shell and connected to the grounding downlead of the counterpoise. This grounding cable should be made of yellow-green plastic insulation copper wire with the core diameter not less than 35mm2.

Each cable has one of its ends equipped with a four-core plug to connect to the UPS. On plugs, labels are attached to tell the positive end (+) and negative end (-). The other end needs to be prepared at site: There are two big OT connectors and heat-shrink tubes; cut the available cable (10m long) between the UPS and the IABB into the piece (with proper length according to the site conditions), then make the OT connector with a crimping piler and then connect the terminal to the connector at the battery. This cable should be led through the inlet at the bottom of the battery box and in. The cable length should be minimized for the sake of lightning protection. Caution: 1) The cables must be connected to the UPS and the battery box correctly with their polarities in correspondence with those at the plugs of the UPS and the battery box. Any incorrect connection will result in the damage of the UPS and batteries. 2) Relabel the cut cable correctly at once if the original label has been damaged when cutting the cable. 2) Cable connection among IAFB, ODU3601C and UPS
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 2 Installing Cabinet Hardware 2-58 It is required to connect cables among IAFB, ODU3601C and UPS according to labels on them, the correspondence shown in Figure 2-55 and Figure 2-56, and the correspondence between labels and cables described in Table 2-4. & Note: Figure 2-56 shows the front view of the cable connection on DDF shown in Figure 2-55.

The following gives description of feeder grounding points in different installation modes. I. ODU3601C outdoor installation mode l Within the range of 1m~2m under the antenna; l The front end connecting the ODU3601C. Caution: 1) When soft jumper is adopted for the feeder and the feeder is not longer than 5m, the shielding covering of the feeder may be grounded at the front end connecting the ODU3601C. 2) If the feeder is longer than 60m, feeder grounding clips should be applied in the middle of the feeder, with the clip spacing of 20m. II. ODU3601C indoor installation with the outdoor feeder longer than 20m l Within the range of 1m~2m under the antenna; l Within 1m range of the mast or of where the feeder is led from the tower platform; l At the outer side of the feeder window where the feeder enters the equipment room (connecting to outdoor PGND bar). l Close to the indoor protection grounding bar after it enters the equipment room. Others: l If the feeder is longer than 60m, feeder grounding clips should be applied in the middle of the feeder, with the clip spacing of 20m. l If the feeder is led into the room after being routed for a stretch of distance on the building-top, and the distance exceeds 20m, a feeder grounding clip should be applied on building-top. l For the feeder that enters the room from the building-top along the wall, if a cabling rack is used, the cabling rack should also be grounded. l Feeder grounding cable should be routed toward the ODU3601C antenna and feeder port along the antenna. The included angle between the feeder grounding cable and the feeder should not be greater than 15°. The feeder grounding clip should be directly secured to the steel board on the nearby tower body. III. ODU3601C indoor installation with the outdoor feeder shorter than 20m l Within the range of 1m~2m under the antenna; l At the outer side of the feeder window where the feeder enters the equipment room (connecting to outdoor PGND bar); l Close to the indoor PGND bar after it enters the equipment room.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 3 Installing RF Antenna and Feeder System 3-30 Caution: 1) When soft jumper is adopted for the feeder and the feeder is not longer than 10m, the shielding covering of the coaxial soft jumper may be grounded at two points, i.e., below the antenna and indoor. 2) When soft jumper is adopted for the feeder and the feeder is not longer than 5m, the shielding covering of the coaxial soft jumper may be grounded at one point indoor. 3.7.6 Leading Feeder into Equipment Room I. Feeder arrangement principle l There are 4 big holes in a 12-hole feeder window, and 3 small holes in each big hole. One feeder can run through a small hole. l The feeders should be arranged in sequence (i.e. clockwise or counter-clockwise) in the three small holes of the same big hole. l The arrangement of feeders in the feeder window should facilitate system expansion. The original arrangement of feeders should not be changed during system expansion. It is permitted to add feeders to the feeder window and change the jumper connection on the cabinet top only. l The arrangement of feeders in the feeder window should facilitate the routing of feeders on the cabling rack and the connection of feeders with the cabinet top. The feeders should be parallel to each other without any cross. l The length of the feeder entering the feeder window should be 30cm~50cm. If there is an indoor cabling rack, the feeder can be fixed with feeder clip. If not, the feeder may be hanged in air. Caution: The minimum feeder curving radius should not be less than 20 times of the feeder diameter. There should be no cross of the feeder when it is routed along the cabling rack and tower cabling ladder. And there should be no crossing or overlapping of the feeder entering the equipment room. Therefore, it is required to get an idea of the feeder routing prior to feeder distribution. It is best to draft the actual feeder routing on paper to avoid rework due to feeder crossing. II. Procedure 1) Make waterproof elbow for the feeder at the outer side of the feeder window.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 3 Installing RF Antenna and Feeder System 3-31 2) Direct the feeders into the equipment room via the feeder window. The corresponding personnel inside the equipment room should guide the operation so as to avoid damage to equipment in the room. 3) Mount sealing gasket and sealing gland. Place the hole for filling in glue on the sealing gland facing upward when mounting the sealing gland. 4) Cut the feeders correctly according to the design requirements. 5) Make the indoor feeder connector. 6) Encapsulate the feeder window and the unused holes with adhesive tape, plaster and glass cement, as shown in Figure 3-38. Figure 3-38 Encapsulation treatment of the feeder window after feeder enters the equipment room & Note: If the feeder needs to run though the window glass, remove the glass first. Cut a corner of proper size of the glass and then use rubber or adhesive tape to protect the edge, in order to avoid the feeder being cut. Measures should be taken to prevent rain after the feeder runs through the glass, that is, seal the connection between the glass and the feeder with glass cement. 3.7.7 Connecting Feeder and ODU3601C The feeder and ODU3601C should be connected with 1/2 jumper. Feeder connector at ODU3601C side has already been connected during the installation of major equipment. Just connect the feeder and jumper. In the case of outdoor installation of ODU3601C, 3-layer waterproof treatment should be performed in addition.

Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-1 Chapter 5 Software Installation and System Commissioning 5.1 Software Installation ODU3601C software indicates the running software of MTRM, which has been installed before delivery and supports the remote loading through OMC. The operation and maintenance of ODU3601C is realized through the upper-level BTS or remote OMC, i.e. the ODU3601C needs no special operation and maintenance software. 5.2 System Commissioning Before starting the ODU3601C, make sure that its upper-level BTS runs normally. Start certain basic operation and maintenance functions for system commissioning after the ODU3601C is power-on and various indicators are normal. Following is to introduce the contents of the system commissioning. 5.2.1 Test Equipment 　I. Call generator It is used to simulate multi-user call setup. II. Test MS 　It is used to test the service functions. 5.2.2 Service Flow Overview When switched on, an MS may be either in the idle mode or the dedicated mode. In the idle mode, the MS will monitor the radio surroundings and find a suitable service cell to stay; then the MS will monitor the paging channel in the service cell so as to receive the paging messages from the network side. In the dedicated mode, the MS exchanges signaling and data with the network. The basic flow is as follows: 1) Location update flow
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-2 2) Mobile Originated Call (MOC) flow 3) Mobile Terminated Call (MTC) flow 4) Handoff flow 5) Mobile originated SMS flow 6) Mobile terminated SMS flow 7) Mobile originated call packet data flow 8) MS packet data flow (downlink service rate) Flows 1), 2), 3), and 4) are of basic radio connection; while flows 5), 6), 7), and 8) can be independent flows, or be additional part of flows 1), 2), 3), and 4). 5.2.3 Test of Location Update Flow I. Test condition The test MS has been defined in HLR. II. Test steps 1) Make sure the network data setting is correct. 2) Switch on the test MS 3) Observe the signaling on Abis interface. III. Expected test result By tracing the signaling on Abis interface, the possible results of the location update include: 1) The network side accepts the MS location update request; 2) The network side rejects the MS location update request. 5.2.4 Test of MOC Flow I. Test condition This test should be conducted after a successful location update flow, when the MS should display the current PLMN No. or operator name. II. Test steps Call a PSTN subscriber with the MS. III. Expected test result In normal cases, the called PSTN subscriber establishes a bidirectional conversation with the MS after ringing and off-hook.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-3 5.2.5 Test of MTC Flow I. Test condition This test must be preceded by a successful location update flow. The called MS should reside in the coverage of the tested ODU3601C, and display the current PLMN No. or operator name of the network. II. Test steps Call the test MS from a PSTN telephone set. III. Expected test result In normal cases, the test MS establishes a conversation with the calling PSTN subscriber after ringing and off-hook. 5.2.6 Test of Handoff Flow　I. Test condition 1) This test should be performed after the above three tests and in the area covered by at least two cells. One of cell should be configured with several sectors, so that the test of the softer handoff can be conducted. 2) The sectors (or omni cells) that compose the overlapped radio coverage should be configured with different frequencies, so that the hard handoff can be conducted. 3) The related handoff data should have been configured; 4) Dedicated test MSs; 5) Change the IMSI of the MS, and redefine the subscriber. In this way, the MS can access the network by selecting a certain basic frequency or auxiliary frequency in the sector (or omni cell) that is configured with multiple frequencies. II. Test steps 1) Use an MS to call a PSTN subscriber and establish a conversation. 2) Move the MS from the source sector to the adjacent sector within the same cell to test the softer handoff performance. 3) Only when the adjacent sector is also configured with the frequency at which the MS has established the conversation in the source sector, and the frequency is available, can the softer handoff be achieved. 4) Move the MS from the source cell to the target cell to test the soft/hard handoff performance.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-4 When the MS establishes a connection at a frequency in the source cell, while the target cell is not configured with this frequency, the hard handoff will occur. If the target cell is configured with this frequency and this frequency is available, the soft handoff will occur. III. Expected test result 1) Soft handoff and softer handoff Normally, when the MS moves to the adjacent cell/sector, the target pilot channel will be shown in the active set of the MS pilot set. During the conversation, the mobile subscriber feels no interruption or call drop, and the voice quality is good. 2) Hard handoff Normally, when the MS moves to the adjacent cell or sector, it is visible in the active set of the MS pilot set that the source pilot channel is deleted, and the target pilot channel is added. The mobile subscriber will feel temporary conversation interruptions. & Note: If the actual test conditions cannot meet the standard, the test flow can be simplified like this: Make an MOC/MTC, and move the MS repeatedly between the adjacent cells, or between the adjacent sectors in one cell. Whether the handoff flow is normal or not can be judged by observing whether or not there are conversation interruptions, and by the voice quality. 5.2.7 Test of Mobile Originated SMS Flow I. Test condition 1) The test should be performed after the location update flow test; 2) The system must be configured with Message Center (MC); II. Test steps Use an idle MS to send an short message through the specified MC.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-5 III. Expected test result In normal cases, the MS that originates the short message will prompt that the short message has been transmitted successfully. The corresponding short message can be queried at the MC. 5.2.8 Test of Mobile Terminated SMS Flow I. Test condition Location update flow test is completed. II. Test steps Input an short message to MC properly. The receiver of the short message is the test MS that is in the idle status. III. Expected test result In normal cases, the called MS will ring to indicate that the MS has received the short message and is ready to display the content of the SM. 5.2.9 Test of Mobile Originated Packet Data Flow I. Test condition 1) A cdma2000 1X MS, a set of BlueRose and a ready FTP server; 2) The system adopts dynamic rate allocation. II. Test steps 1) Use the BlueRose to control the process of the test MS logging in to FTP server, and originate the FTP downloading; 2) Observe the signaling flow and the status transition of MS on BlueRose; 3) Check the channel setup of the sector. III. Expected test result 1) The MS successfully logs in to the FTP server, and transits from the idle status to the downloading status. 2) After the Fundamental Channel (FCH) is set up, ODU3601C repeatedly issues the ESCAM message and performs the Supplemental Channel (SCH) setup or SCH extension.
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-6 5.2.10 Test of MS Packet Data Flow (Downlink Service Rate) I. Test condition 1) The system adopts dynamic rate allocation; 2) A cdma2000 1X MS, a set of BlueRose and a ready FTP server; II. Test steps After the MS logs in to the FTP server under the control of the BlueRose, originate the FTP file downloading, and test the downlink rate of a single subscriber under the following conditions respectively: --The adjacent cell and target sector are not loaded. The MS is stationary, and is within short distance to the ODU3601C. --The adjacent cell and target sector are not loaded. The MS is stationary, and is within long distance to the ODU3601C. --The adjacent cell and target sector are not loaded, and the MS is moving (15, 30, 70km/h), and is within short distance to the ODU3601C. --The adjacent cell and target sector are not loaded, and the MS is moving (15, 30, 70km/h), and is within long distance to the ODU3601C. --The adjacent cell is 100% loaded. The target sector is 50% loaded. The MS is stationary, and is within short distance to the ODU3601C. --The adjacent cell is 100% loaded. The target sector is 50% loaded. The MS is stationary, and is within long distance to the ODU3601C. --The adjacent cell is 100% loaded. The target sector is 50% loaded. The MS is moving (15, 30, 70Km/h), and is within short distance to the ODU3601C. --The adjacent cell is 100% loaded. The target sector is 50% loaded. The MS is moving (15, 30, 70Km/h), and is within long distance to the ODU3601C. III. Expected test result In normal cases, the downlink data service rate keeps stable. & Note: There are multiple test conditions listed in the test steps. It does not mean that all of them are necessary during the actual test. 　
Installation Manual iSiteC ODU3601C CDMA Soft Base Station Chapter 5 Software Installation and System Commissioning 5-7 5.2.11 Processing of Abnormalities in the Test In normal cases, the above flows can pass the test. When abnormalities occur in the test, they cannot be all attributed to the fault of ODU3601C. The service flow test does not only test ODU3601C, but also the whole CDMA 1X system. The parts tested include BTS3612, ODU3601C and BSC6600 of BSS. Besides, also tested are MSC/VLR, HLR, and AUC of the NSS and their interfaces to PSTN and Internet. The fault of any part of the system may result in the failure of the flow. Therefore, the analysis should be made based on the actual conditions when a fault occurs. ODU3601C is responsible only for the radio transmission. If the MS can access the network and set up the radio service link, then we say the ODU3601C is in normal operation. Take the location update flow as the example. If a location update request is rejected, basically it is due to the abnormality of the network equipment, or to be more specific, the problem with the data setting of HLR. Based on the rejection reason in the message for the rejected location update, further cause for the rejection can be figured out.
