4.2.5 Optional Modules Characteristics

4.2.5.1 External Alarms Module (Optional)

A specific Alarm distribution frame should be considered. It must be grounded.

The external alarm kit provides up to 16 external alarms and up to 6 remote control. This kit consists of one module (IEA) equipped with 2 digital cables and one ground cable. This external alarm module is located in the MCPA shelf on the right hand side slot when viewed from the front of the cabinet (see Figure 3) to adapt the alarm 2 remote control loops to the internal alarm bus.

The 16 external alarms and 6 remote control are shared on 2 cables (8 external alarms and 3 remote control per cables). The normal state (no alarm) is a closed loop. That means when the loop is open, an alarm appears at OMC. As a consequence, each equipment connected to the external alarms should be "closed" in a normal state.

Regarding the remote control, when the contact is closed, the maximum current is 150 mA and the serial resistor is 10 Ohms. When the contact is open, the maximum switching voltage is 60V.

Dc Power Source Requirements

The NAM has an integrated 300W power supply. The terminal block for the -48V dc power input is located on the rear panel of the shelf.

In -48 V dc installations (typically North American), power feeds into the system require a 60 V dc rated circuit breaker or fuse.

In -60 V dc installations (typically European), power feeds into the system require an 80 V dc rated circuit breaker or fuse.

In all cases the circuit breaker or fuse must be rated for 10 A dc and have appropriate regulatory approvals.

Dc Power Input and Wiring Requirements

You must supply your own 12 AWG or 14 AWG dc power wiring. Wiring must be

• approved for use in the country of installation

• rated for 10 A dc

• protected with a 10 A circuit breaker or fuse

The nominal input voltage can be -48/-60 V with an input operational range of -39 to -72 V. The maximum output power for each dc supply is 300 W.

Input voltage under minimum battery operating conditions must supply a minimum of -36.0 V to the power supply. The maximum dc wire length for a voltage drop of 1 V using 14 AWG wire is 12.2 m (39 ft) and for 12 AWG wire is 19.6 m (62 ft).

Note: A length of 12.2 m is the distance from the power source to the unit. Total loop length (battery and battery return) is double this length.

North American installations must use plain crimp ring lugs (insulated) with a #8 stud size and either a 12 AWG or 14 AWG wire to connect to the power supply terminal strip.

European installations must use plain double crimp ring lugs (insulated) approved for European requirements with a #8 stud size and either a 12 AWG or 14 AWG wire.

Note: Ring lugs must be insulated to prevent accidental electric shock.


July 25, 2003 Method 06-9434

Grounding Requirements

Passport is grounded to protect both personnel and equipment and contains a separate ground stud located on the rear housing.

For further information on grounding, see 241-7401-240 Passport 7400 Hardware Installation, Maintenance and Upgrade.

Cabling Requirements

If you have a fully-configured switch with 13” rear-mounted termination panels, you will get the best cable routing between the lower cable organizer and the cable-support guide if:

• cable diameters do not exceed 0.8 cm (5/16 inch)

• cable flexibility allows for a bend radius of 2.5 cm (1 inch).

For more information see 241-7401-200 Passport 7400 Hardware Description "cables."

Compliance to Electrical and Safety Standards

Passport switches comply with both North American and international regulatory safety requirements.

4.3 Co-Location Issues

4.3.1 Co-Location Particularities

As the UMTS network is a new coming system, the operators might be looking for solutions of co-location between GSM BTS and new UMTS BTS on the same site for different reasons: Difficulty of finding new sites, cost reduction, environmental issues...

In the analysis of co-location, different interferences occur (like spurious emissions, wideband noise, blocking, intermodulation products, or electromagnetic problems). For each type of interference, the necessary isolation between different systems should be achieved to avoid any disturbance. The isolation can be obtained by different ways (antenna decoupling, use of filters…).

CAUTION/WARNING:Damage to equipment by electromagnetic interferenceTo meet electromagnetic interference (EMI) regulatoryrequirements and thermal specifications, all blank slotsmust be fitted with a blank function processor faceplate.


Method 06-9434 July 25, 2003

Some co-siting phenomena must be studied concerning the existing GSM sites which are in compliance with GSM specification fixed before the arrival of UMTS. As the spurious emissions from GSM BTS within the UMTS receiving band have not been specified at a controlled level, the potential interference risks from GSM BTS to UMTS BTS in co-location case exist: Anyway, these problems cannot be forecasted and must be treated on site, case by case. For more information, refer to your site engineering prime.

Figure 24 – Example of GSM – UMTS Co-location

4.3.2 Sharing Particularity

The iBTS Indoor 2 could be divided between two (or several) different operators (customer) with intend to optimize the site.

4.4 Site Requirements

4.4.1 Site Access

Once a site has been selected, access conditions should be evaluated to determine whether the cabinet should be delivered populated (easy-access site) or depopulated (difficult-access site).

The access conditions must comply with cabinet dimensions and the available moving equipment.

The packaging can be remove to get over an obstacle (door or staircase...) but keep some protection of the iBTS Indoor 2 (Antistatic bag or vapor barrier or blanket...)

iBTS Indoor 2 UMTS


July 25, 2003 Method 06-9434

The iBTS Indoor 2, the User/Option Rack 19" and the DC/DC Converter with its Shelf are delivered separately.

4.4.1.1 Easy Access Site Characteristics

• The site access conditions allow the mechanical handling of a populated cabinet throughout the distance separating the delivery point from the mounting location without manual carrying.

• The mechanical means used to carry and/or hoist the fully populated cabinet (e.g. dolly system, elevator, ...) must be qualified to bear the fully populated cabinet weight (about 320 kg/ 706 lb) in compliance with standard security requirements.

4.4.1.2 Difficult Access Site Characteristics

• For this type of site mechanical means cannot cover the entire delivery to mounting location distance; part of the way (as small as it might be) requires manual carrying. As a consequence, the cabinet can be depopulated to reduce its weight and height (by swinging).

• Even though the cabinet can be carried manually, the maximum use of mechanical means is encouraged to enhance the safety and security of both staff and equipment.

4.4.2 Cabinet Handling

Otherwise specified the term ‘the cabinet’, in this chapter, refers to an iBTS Indoor 2 cabinet without User/Option Rack 19" and DC/DC Converter option.

The iBTS Indoor 2 cabinets are delivered upright with a corrugated cardboard sleeve on a wooden pallet in case of road transport. They are delivered lying in plywood crates in case of air and sea transports. In all cases, the specific packing allows their handling by means of a fork-lift truck.

The equipment should be unpacked as close as possible to their precise mounting location.

The path from the delivery point to the mounting location should be clear of any obstacle.

The cabinet can be carried either in vertical or horizontal position (in populated or depopulated configuration (refer to IM 53-9404 Univity UMTS iBTS Indoor 2 Depopulation, Repopulation Procedure).

4.4.2.1 Lifting

The populated iBTS cabinet must be handled with mechanical devices (the cabinet may only be guided manually during lift-off or during final


Method 06-9434 July 25, 2003

positioning, provided that basic safety rules are observed by the personnel).

All other handling methods must be specified and validated if required by the project. The cabinets are hoisted with 4 hoisting rings type, by a lifting vehicle suited to the cabinet weight and to the site characteristics (height...).

• No specific tool to lift the iBTS Indoor 2.

• 4 hoisting rings (M10) with strap (useful load 500kg/1102Ib) are the tools for the top of the iBTS Indoor 2 cabinet.(see Figure 51 and Figure 3).

• A specific manual carrying by 4 installers (mover profile) or a specific mechanical carrying by 2 installers means is needed to install this iBTS Indoor 2.

4.4.2.2 Horizontal Moving

• A standard forklift/dolly is used to move the cabinet, secured to its wooden pallet.

• The path should be clear of obstacle (gravel’s, cableway, conduits ...).

4.4.2.3 Moving a Depopulated Cabinet

The access to reach the building entrance from the truck should respect the following minimum dimensions are given under. :

Note: Lift / Elevator: Capacity of 650 kg for a populated cabinet. Capacity of 400 kg for a depopulated cabinet. Check that the lift / elevator max. load is sufficient to lift the cabinet, its means of handling and personnel simultaneously.

4.4.3 Floor

The iBTS Indoor 2 cabinet can be installed either on a concrete floor or on a raised floor.

The floor covering must be antistatic (about 1MOhms) or the technician must use an antistatic bracelet.

In case of raised floor installation, all raised floor supports must be earth equipotentialized.

In seismic regions, where raised floors are mandatory, cabinets are installed on the same metallic support with additional vibration absorbers.

The site which receives the iBTS Indoor 2 must comply with standard rules for installation in indoor premises (refer to [R1], [R2], [R5], [R6]).

4.4.3.1 Resistance

iBTS cabinet: In accordance to cabinet weight, the minimum floor resistance should be: 700 kg/m², 123 lb./ft².

Note: In case of floor resistance value close to the previous one, an additional securing point to the wall or a load spreading structure on the floor is advised.

4.4.3.2 Floor Flatness

The iBTS Indoor must be installed on a level floor surface. The maximum tolerance for floor flatness is 5mm over 2m (~ 0.2’’ over 78’’). In other words, the vertical tolerance shall not exceed 5mm over a 2m horizontal length.

If the BTS pad does not respect this maximum tolerance, the cabinet once installed may be ‘twisted’ and the cabinet door might be impossible to open. The adjustable feet can be used for taking up of play.

4.4.4 Site Dimensioning Rules

The criteria governing the size of the site are:

• The cabinet dimensions and the distance constraint,

• The relative positions of cabinets,

• The input constraint of coaxial cables,

• The use of the User/Option Rack 19" with the DC/DC Converter.

4.4.4.1 Cabinets Positions and Distance Constraints

Each site can be constituted of one iBTS cabinet plus one optional User/Option Rack 19" with the DC/DC Converter. The clearances considers the clean surface which is the minimum surface required to install the cabinet and allow the different field technicians to move along the cabinet when installing or servicing it. The clean surface is described in the given sample layouts.A minimum clearance is required around the cabinet.

• -48Vdc: Nominal DC voltage range: -57Vdc< V < -40.5Vdc.

• +24Vdc: Nominal DC voltage range: +20Vdc< V < +31Vdc.(iBTS Indoor 2 with a DC/DC Converter)

4.5.4.1 iBTS Indoor Customer DC Power Supply Box

For a site with several cabinets, one protected power supply branch is required for each equipment installed on the site.

The DC customer box is not provided by Nortel. The location of the DC customer box must take into account the length of the cables connected to the BTS (max 16 m / 52.5ft for the cables provided with the ancillaries kit).

The DC boxes must contain an appropriate disconnect device, easily accessible by the service personnel and marked as the disconnect device for the equipment.

The cables used for powering each BTS cabinet must be able to hold at least 50 Amps (AWG 1/0), and are dimensioned according to the distance between the cabinet and the customer DC box.

The voltage drop due to cable resistance must be so that the voltage at the cabinet level is in the window given in the power supply paragraph.

The DC boxes must be dimensioned according to the connected systems characteristics. The insulated earth conductor for the product must be green/yellow.

The DC box feeding one cabinet must be dimensioned to feed one fully equipped BTS cabinet in the worst case configuration (cooling / heating on, all equipment broadcasting, max current drawn on DC plug, dc input voltage variation).

During the start-up of the climatic system, the current drawn by the BTS may be higher for a short period of time. This is why the site breaker must be time delayed.

Method 06-9434 July 25, 2003

Power supply cables must be labeled (see "4.6.4 External Cables Marking").

4.5.7 DF for PCM Connection

The iBTS Indoor 2 is not connected directly to the telecommunication network, but by means of a DF. This DF is a connection point between the PCM cable from the iBTS, and the transmission network. Refer to Figure 49 – Example of DF for PCM and Alarm Cables. A DDF must be grounded.

For isolated bonding network (IBN) the PCM screens cable and pairs are connected to the ground on one end only (equipment side).

For the common bonding network (CBN) the PCM screens cable and pairs are connected to ground on both ends (equipment and DDF sides).

There are two major cases for the connection to the PCM link:

• Or the telecommunication network is 120 Ω E1 or 100 Ω T1, in that case the only equipment necessary to ensure the PCM connection between the DF and the iBTS is the PCM cable.

• Or the telecommunication network is E1 75 Ω, in that case, as the iBTS works in 120Ω, it is necessary to ensure an adaptation from the iBTS’s 120 Ω to the customer network’s 75 Ω. As a consequence, the PCM cable should be equipped with Mini-Baluns male, and the DF should be able to receive it.

1 type of cable is supplied according to the site configuration E1 or T1 :

• 8 Twisted pairs 120Ohms E1 PCM cable (+ balun 75Ω if E1 75Ω ).

• or 8 Twisted pairs 100Ohms T1 PCM cable.

For lightening protection it is important that the radio lines from the antennas to the cabinet are regularly grounded with dedicated grounding kits. (refer to Figure 50).

Figure 50 – Lightning Protection on Feeders

Note: In case of TMA are employed, the site should be equipped with specific surge arrestor as "gaz tub" in order to avoid short circuit between the inner and outer connector of feeder (the TMA is supplied in DC voltage thanks to its RF cables).

4.5.13 Feeders

Feeders are used to establish the link between the iBTS Indoor 2 cabinets and the antennas or TMAs.

The feeders are located on the top left or right of the radio cabinet, ready to be connected to the jumpers.

It is recommended to use the jumpers between the iBTS and feeders.

A female 7/16 connector equips each feeder end.

In case of site with dual band configuration, label the feeders with a specific marking for each frequency band.

The position of the antenna feeders must respect the bending radius of the cable and of the antenna jumpers.

On the iBTS side, the feeders should arrive as close as possible to the iBTS Indoor 2 cabinet mounting location.

The number of feeders depends on the configuration type. (refer to IM 04-9405 Univity UMTS iBTS Indoor 2 Cabling Referential) in order:

• To allow an easier installation: depends on the size of feeder used, it might be very difficult to position correctly the feeder in front of the RF connector on BTS side.


Method 06-9434 July 25, 2003

• To avoid excessive efforts on the RF connector on the BTS side: risk to damage the connector and potential waterproofing issue with the time.

• To allow easier maintenance operation.

The Cable used for feeder should have a maximum attenuation of 6.99dB/100m at 2300Mhz. Couple connector losses = 0.2dBmax.

In all cases, network designer must be informed about the end to end attenuation measured at the end of the installation: it might be necessary to modify parameters at the OMC-R.

4.5.14 Antennas

The customer must foresee and install the antennas and the feeders. The antennae are installed in compliance with the radio engineering studies by trained staff.

The UMTS iBTS Indoor 2 could used TMA, refer to "4.2.5.3 TMA Equipment (Optional)".

4.6 Site Wiring

4.6.1 IBTS Indoor External Connectors
