SIST EN 300 908 V7.5.1:2003 is the Slovenian adoption of EN 300 908 Version 7.5.1, published by SIST. It covers Digital cellular telecommunications system (Phase 2+) (GSM) and defines how the radio path is multiplexed and accessed, including the physical channels, burst formats, timing structure and channel-mapping rules used in GSM radio subsystems for GSM900 and DCS1800.

Engineers, network planners, and equipment suppliers use SIST EN 300 908 V7.5.1:2003 to align base station and mobile station behavior with GSM channel structure. It is also relevant for packet services and CTS functions where exact time and frequency mapping matters.

What does SIST EN 300 908 V7.5.1:2003 specify?

SIST EN 300 908 V7.5.1:2003 specifies the physical channels of the GSM radio subsystem that support the logical channels. It also covers frequency hopping, TDMA frames, timeslots and burst formats, and it explains how logical channels are mapped onto physical channels.

The document is organized into:

• Clause 1 - scope, references and abbreviations
• Clause 2 - general overview
• Clause 3 - logical channels
• Clause 4 - physical resource
• Clause 5 - physical channels and bursts
• Clause 6 - mapping of logical channels onto physical channels
• Clause 7 - mapping tables used by the clauses

Annex	What it covers
Annex A	Phase 2 mobiles in a Phase 1 infrastructure
Annex B	Multislot capability
Annex C	CTSBCH timeslot shifting example
Annex D	Change control history

What are the key requirements of SIST EN 300 908 V7.5.1:2003?

Logical channel families and service types

SIST EN 300 908 V7.5.1:2003 divides logical channels into traffic channels and control channels in clause 3. That matters because the same radio resource carries speech, circuit-switched data, packet data, paging and access signaling, but each service uses a different channel type.

The document defines full-rate and half-rate traffic channels, packet data traffic channels, and several speech and data variants. In practice, implementers must choose the right channel family for the service and then follow the corresponding mapping rules.

Physical resource, timeslots and TDMA frames

Clause 4 defines the radiofrequency channels, the cell allocation (CA), the mobile allocation (MA), timeslot number (TN) and TDMA frame number (FN). A time slot lasts 3/5200 seconds, eight timeslots form a TDMA frame, and the frame numbering continues cyclically up to a hyperframe.

This structure matters because GSM behavior depends on exact frame timing. Base stations and mobiles must share the same frame reference, and hopping sequences depend on the FN, MA, MAIO and HSN parameters.

Burst formats and guard periods

Clause 5 defines the main burst types: normal burst (NB), frequency correction burst (FB), synchronization burst (SB), dummy burst and access burst (AB). It also explains the guard period between bursts and the role of ramp-up and ramp-down.

This is the practical interface between symbols and time slots. Equipment designers use these burst definitions to build transmit timing, receiver synchronization and measurement behavior.

Mapping in frequency and time

Clause 6 explains how logical channels are mapped onto physical channels in both frequency and time. It covers hopping sequence generation, the use of BCCH carrier C0, packet mappings on PDCHs, and CTS-specific mapping rules.

This matters because one logical channel may move across RF channels from frame to frame, while its timeslot number stays fixed. The mapping tables in clause 7 show the exact repeating frame patterns used for traffic, control and packet channels.

Control-channel operation and paging groups

Clause 6.5 defines how mobiles determine CCCH_GROUP, PAGING_GROUP, PCCCH_GROUP and CTS_PAGING_GROUP, and how they monitor paging and access blocks. It also covers BCCH and PBCCH scheduling, SMSCB on CBCH, NCH for voice group and voice broadcast calls, and CTS paging behavior.

In practice, this tells a mobile when to listen, which blocks to decode, and where the network may place paging or access information. It is important for battery life, call reachability and packet access behavior.

Multislot use

Annex B defines multislot classes, the maximum number of receive and transmit timeslots, and timing constraints such as Tta, Ttb, Tra and Trb. Clause 6.4 also lists permitted multislot combinations.

This is the basis for higher-capacity devices and services such as HSCSD and packet multislot operation. A network must check the mobile’s class before assigning more than one timeslot.

What terms does SIST EN 300 908 V7.5.1:2003 define?

• Traffic channel (TCH) - A channel used for encoded speech or circuit-switched user data.
• Packet data traffic channel (PDTCH) - A channel used for packet-switched user data, with separate uplink and downlink forms.
• Common control channel (CCCH) - The set of paging, random access, access grant and notification channels used for common access control.
• Packet Broadcast Control Channel (PBCCH) - The packet control broadcast channel that carries packet-access parameters and repeats BCCH information for GPRS attached mode.
• Packet Common control channels (PCCCH) - The packet paging, random access, access grant and notification channels used for packet-switched access.
• Hopping sequence number (HSN) - A parameter that selects the hopping sequence generation method.
• Mobile allocation index offset (MAIO) - An offset used when deriving the hopping channel index.
• Training sequence code (TSC) - The code that selects the training sequence in a burst.

Who uses SIST EN 300 908 V7.5.1:2003?

SIST EN 300 908 V7.5.1:2003 is used by GSM radio engineers, base station and mobile station designers, interoperability test teams, and network operators. It is also useful for quality managers and buyers checking that equipment supports the right GSM channel types, multislot behavior, packet channels and CTS operation.

What changed in SIST EN 300 908 V7.5.1:2003 from the previous edition?

SIST EN 300 908 V7.5.1:2003 is the publication of Version 7.5.1. The change control history records clarifications to PBCCH message scheduling and FCCH decoding for multislot MS as the latest listed changes before publication.

Which standards are used with SIST EN 300 908 V7.5.1:2003?

SIST EN 300 908 V7.5.1:2003 refers to several companion GSM specifications:

• GSM01.04 - abbreviations and acronyms
• GSM03.03 - numbering, addressing and identification
• GSM04.03 - channel structures and access capabilities
• GSM04.08 - MS-BSS layer 3 signaling and many broadcast parameters
• GSM05.03 - channel coding
• GSM05.04 - modulation
• GSM05.05 - radio transmission and reception
• GSM05.08 - radio subsystem link control
• GSM05.10 - synchronization
• GSM03.64 and GSM04.60 - GPRS radio interface and RLC/MAC behavior
• GSM03.52, GSM04.56 and GSM05.56 - CTS lower layers, layer 3 and CTS-FP radio subsystem

What does the SIST EN 300 908 V7.5.1:2003 document contain?

The document contains the channel definitions, timing rules, mapping algorithms and allowed channel combinations needed to implement GSM radio access. Clause 7 provides the tables that assign each logical channel to timeslots, frames, burst types and repeat patterns.

It also includes figures for the physical resource, burst formats, frequency hopping, TDMA mapping, and CTS timing structures. Annex C gives a worked CTSBCH timeslot shifting example, and Annex D records the change history.
