Site LAN Interface including Local O&M

A

External alarm interface

Transmission: E1/T1/J1 or STM-1 (unchannelized)

A site LAN is used to communicate with the RBS Element Manager (RBS EM) or Moshell, which in turn can be used to connect a thin client to the RBS3518 for configuration and service purposes. To connect to the site LAN, route a crossed transmission cable through the cable sealing module at the bottom of the RBS 3518 and plug its RJ-45 cable connector into the cable inlet located above the Surge Protection Device(SPD). See beside picture.

OIL Interface

The OIL interface carries traffic and timing signals between the RBS 3518 and each RRU. The OIL cable is routed to the OBIF2 (or OBIF4) board through the cable sealing modules at the bottom of the RBS 3518. see the beside picture.

Transmission Interfaces

The connection interface at the bottom in the RBS 3518 is equipped with a plate of cable sealing modules, with each module intended for sealing three cables. As the cables to be used can be of various diameters, it is possible to change the diameter of the hole in each module.

External Alarm Interface

The external alarm interface is a push-in connector. As shown in beside picture. Two OVP modules are used to make the external alarms available.

ESD Interface The Electrostatis Discharge (ESD) interface provides a connection point for the ESD wrist strap, which protects boards and units from being damaged by electrostatic discharge from anyone working with them.

Earth Grounding Interface The single earth grounding point for the RBS 3518 is the threaded stud.

Power Interface

The power interface accepts cables with a cross-sectional area of up to 4 mm2, and a minimum of 2.5 mm2 is recommended. Only multistrand cables can be used. The power is connected to the PDU through the SPD. The SPD and Connection Field are covered, as picture beside.

Optical Baseband Interface (OBIF) board


The connection between the MU and the RRU is made by an Optical Interface Link (OIL). There are several different lengths available for the OIL cables: 20, 70, 150, 250, 350 and 500 m. The OIL must have zero-dispersion in the wave length range 1302 – 1322 nm. For longer distances between MU and RRU an already installed optical fiber transmission network, e.g. Dark Fiber, can be leased and used to increase the total length of the OIL. The OIL cable(s) is connected to the leased optical fiber transmission network by a connection box. The maximum length of the OIL (OIL cable, or OIL cable and leased optical fiber) is 15000 m. It is important that the leased optical fiber has a fixed delay and that the uplink and downlink fiber have the same delay, within 8 ns. This corresponds to less than 1.5 m difference between uplink and downlink fiber. The total delay for the entire OIL connection must be less than 75 µs in each direction. This corresponds to 15 km fiber in each direction. The total optical attenuation for the entire OIL connection must be less than 15 dB, in each direction

ESD interface

Transmission Interface E1 or Ethernet The connection interface on the top of the MU is equipped with eight female RJ-45 connectors, see the figure below. An internal connection is made from the connection interface to the ET-MC1 or ET-MFX board in the MU subrack.

To support the 75 cable impedance, the MU can be delivered with one or two transmission adapters (Miniwift) installed on the top of the cabinet. The transmission adapter, consisting of eight BNC connectors, is a converter between the 75 coaxial interface and the 120 twisted pair aimed for the E1 interface. The signal is transformed to 120 in the transmission adapter, and distributed to the 120 transmission connector panel and then further to the ET board.

OIL Interface

The OIL interface carries traffic and timing signals between the MU and each RRU. The OIL cable is routed to the OBIF board through up to three holes on the top of the MU.

Site LAN Interface Including Local O&M

SiteLAN is used for communication with the Base station Element Manager (BEM). A Thin Client can be connected to the MU for configuration and service purposes by using the BEM. The interface consists of an RJ-45 connector.

Power Interface

The power interface is protected by a plastic cover. The cables can be connected without removing the cover. The power interface accepts cables with an area up to 6 mm , a minimum cable area of 2.5 mm is recommended. The cable should be a multi strand cable. The power is connected directly to the CUX board using the DC input terminals.

External Alarms Interface

The external alarm interface consists of a 37 poled female D-sub connector

Connection Interface Top View Cabinet This section provides information about the interfaces on the RBS. The Connection Field (CF), the interfaces for earth grounding, power and antennas are located on the RBS cabinet top. The CF includes 22 slots beginning from the left. The CF is used as the interface to the cabinet boards. The CF is modular and contains the interfaces for transmission, local Operation and Maintenance (O&M) and Auxiliary Unit Hub (AUHub).

Power Connection Interface The power connection interface is located on the cabinet top in a black protective box, called DCCU (DC Connection Unit). The maximum dimensions for each power cable is 70 mm and the power connectors are two M8 screws with washers and M8 cable lugs.

Antenna Connection Infterfaces

The antenna connection interfaces are located on the cabinet top; three antenna feeder connectors on each side. The connectors are 7/16 IEC-169-4 female connectors. The connectors are labelled H1 to H3 and J1 to J3, see beside picture. The antenna cables must be connected as follows:      

The E1, T1, J1 connection interface in the CF is equipped with eight female RJ-45 connectors for the ET board cables, see beside picture. The ET-M1 board and the ET-MC1 board each has support for up to eight T1, J1, or E1 transmission lines connected in four RPV 431 connectors in the board front

STM-1 The STM-1 connection interface, located in the CF in positions T09 and T11, is equipped with two pairs of female SC connectors. An internal connection is made from the CF to the ET-M4 or ET-MC41s board in the BB Subrack.

Site LAN Interface

The connector for local O&M is an 8-pin, non-keyed, female RJ-45 connector located in the CF in position T17A. See beside picture. Ethernet cables can be connected to the O&M interface. The connector in position T17B is provided for redundancy
