1 Scope
This European Telecommunication Standard (ETS) defines a data profile for Digital Enhanced Cordless
Telecommunications (DECT) systems conforming to ETS 300 175, Parts 1 to 9 [1] to [9]. It is part of a
family of profiles that build upon, and extend, each other, aimed at the general connection of terminals
supporting non-voice services to a fixed infra-structure, private and public.
This ETS defines the type C service, mobility class 1, as described in ETR 185 [13].
For the type C service, this ETS specifies a Link Access Protocol service for the DECT Link Access
Procedure for the User plane (LAPU) which adds full DLC functionality to the generic frame relay service
specified in ETS 300 435 [11]. LAPU is based closely on the existing LAPC service and, allied with the
generic frame relay service, offers a robust, non-transparent transfer mechanism for synchronous and
asynchronous bit streams. It builds upon the type A and type B generic frame relay services and is
therefore fully compatible with both.
This ETS is intended for use in closed user groups and therefore specifies mobility class 1. It contains no
requirements for Mobility Management (MM) or Call Control (CC) and, hence, requires no DECT Control
plane (C-plane) functionality.
This ETS defines the specific requirements on the Physical (PHL), Medium Access Control (MAC) and
Data Link Control (DLC) layers of DECT and on ETS 300 435 [11]. The ETS also specifies Management
Entity (ME) requirements and generic interworking conventions which ensure the efficient use of the
DECT spectrum.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
kbyte: 1 000 bytes.
mobility class 1: Local area applications, for which terminals are pre-registered off-air with one or more
specific fixed parts, and establishment of service and user parameters is therefore implicit, according to a
profile-defined list.
multiframe: A repeating sequence of 16 successive TDMA frames, that allows low rate or sporadic
information to be multiplexed (e.g. basic system information or paging).
service type A: Low speed frame relay, with a net sustainable throughput of up to 24 kbits/s, optimized
for burst data, low power consumption and low complexity applications such as hand-portable equipment.
service type B: High performance frame relay, with a net sustainable throughput of up to 552 kbits/s,
optimized for high speed and low latency with burst data. Equipment implementation the type B profile
shall inter-operate with type A equipment.
service type C: Non-transparent connection of data streams requiring Link Access Protocol (LAP)
services, optimized for high reliability and low additional complexity. This builds upon the services offered
by the type A or B profiles.

TDMA frame: A time-division multiplex of 10 ms duration, containing 24 successive full slots. A TDMA
frame starts with the first bit period of full slot 0 and ends with the last bit period of full slot 23.
