DEFINITIONS 8PSK

8 states Phase Shift Keying modulation. The modulation used for EDGE is a 8PSK with an additional constant shift of 3 Π/8 at each symbol change.

Abis

ETSI generic name of BSC-BTS interface. The Abis covers both the physical interface (PCM) and the protocols. Protocols are splitted in a TMG part and an O&M part, the former being mostly compliant with GSM 08.58, the latter being NMC

BTS 18000 GSM Indoor Outdoor Engineering Rules proprietary. Abis PCM

2.048 Mbit/s for E1 (or 1,544 Mbit/s for T1) physical link (HDB3 or B8ZS) where the clock is synchronous with the radio transmission.

Cabinet/shelf/rack In the document, the term cabinet point out the total enclosure of the equipment, as well as the entire equipment (enclosure+cabling+modules). Two versions of cabinet is described in this version of document BTS18000 Indoor cabinet and BTS18000 Outdoor. The term Rack is used to point out two physical sub-assembly: •

Combiner Rack: one stage of combiners equipments

•

Digital rack: one stage of digital and radio modules.

The term Shelf is used to point out the association of these two racks. Cavity

An association of ive RF frequency selective filters to combine a

dB

number of Transceivers onto one antenna. It includes a Diplexer unit. decibel. Dimensionless, it expresses a ratio.

dBm

decibel milliwatt. A logarithmic unit to express a power level, with reference to 1 mW. In radio, this reference is taken on a 50 Ohm load, while in telephony this is 600 Ohm.

Diplexer A frequency band selective circulator. Used, as any multiplexor, to minimise the number of physical transmission lines. For radio, transmission line are antenna system. DLU

A DLU contains all the hardware characteristics of the configuration of the BTS. This parameters are ed to the BTS and are used at initialisation stage.

Drop & Insert A technique allowing to daisy chain several components on a common physical bus, each components ensuring data integrity and positioning. DRX

Driver + Receiver + Frame Processor. A stand alone low RF level TRx ( No PA) Note that “DRX” describes any generation of DRX, including eDRX

EFT

“Ensemble de Fichiers Transferables”, french abbreviation for “set of transferable files”. An EFT contains a list of software (and DLU) files to to a BTS and their associated catalogue file; this catalogue file contains information about the software version and the files to , that are used by the BSC to manage the BTS ing.

Extension BTS18000 BTS18000 cabinet installed as “extension” cabinet synchronized with S8000 CBCF main cabinet (with CMCF_ph2) or with a S12000 main cabinet. Granularity

Module granularity is defined as its number of TRXs capacity in a sector. Example: DRX has a granularity of 1, RM in O3 mode configuration a granularity of 3. RM in S111 mode configuration a granularity of 1.

Greenfield

BTS site made of only BTS18000 cabinets

GMSK

Gaussian Minimum Shift Keying. The modulation used in GSM system for air interface (except for EDGE)

HYBRID (3 dB combiner). A ive two input ports device INDOOR Equipment to be installed at locations that are protected from the local weather influences. However some conditions may not be totally excluded. LNA

Low noise amplifier. An RF amplifier used to enlarge very small useful received signals with a minimum added noise.

OUTDOOR

Equipment to be installed at locations that are totally open to local weather influences.

Private PCM

2.048 Mbit/s physical link (V11) where the clock is synchronous with the radio transmission.
