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.

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.

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.

III. 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

angle 30°C between them), as shown in Figure 2-5. 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;

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.

IV. Procedures
Installing the box on wall
1) Put the lightning protection box against the wall and mark the positions where the
four expansion bolts are to be installed. The sizes of holes for expansion bolts are
shown in Figure 2-33.
2) Drll holes with a percussion drill (drill bit v10) at the marked position on the wall.
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 hole must be relocated and drilled again.
Caution:
1) Hold the drilling bit vertical to the wall during drilling. Hold tight the drillstock with two hands to keep it in
the right direction, as vibrations may lead to damaged wall 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 wall is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the
hole.
3) Unfix the washer and nut from the expansion M8%80 bolt, put the expansion bolt
and the expansion sleeve vertically into the hole and strike the bolt with a rubber
hammer until the expansion sleeve is completely driven in the hole.
4) Pull the four expansion bolts through the four hangers of the box.
5) Put the plain washers, spring washers, and nuts onto the exapnsion bolts, revise
the location of the box, and tighten the nuts to a torque of 13.4 N$m. Figure 2-35

"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.

&
Note:
In terms of its discharging currents, the AC lightning protection box can be classified into three types: 20kA,
40kA and 100kA. 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.

3) Grounding cable of the AC lightning protection box
Inside the box, there is a grounding bar. 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).

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.

Following are their detailed cable connections:
1) Cable connection between UPS and IABB
UPS connects to the IABB via two cables, i.e. one is negative cable and the other is
positive cable. 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

3) Make sure that the installation direction of the antenna support would not influence
the receiving (RX)/transmitting (TX) performance and direction adjusting of the
antenna.
4) If necessary, take suspension measures to avoid distortion of the antenna support
as it will be in use for a long time.
5) Whirling arm should be reinforced by reinforcing arm. The length of expansion arm
and whirling arm may be determined according to the onsite situation. The fracture
should be soldered with cover plate to avoid leaking water.
6) All the soldered parts should be secure enough without dry joint and open solder
point. The surface of the support should be covered by anti-rust silvery paint.
Better choose zinc-coated steel for the support.
III. Installation procedure
1) Install a fast pulley on the tower top. Use one or two lifting ropes to hoist the
support to the tower platform via the fixed pulley. Besides, a rope is needed to
control the upward direction of the support;
2) Determine the installation position of the antenna support on building-top
according to the antenna and feeder installation diagram in the engineering design
drawing.
3) Fix the support on the tower with a U-shape fixing clip, as shown in Figure 3-14.

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.

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.

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.

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.

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.

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.

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.

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.
