Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Digital Enhanced Cordless
Telecommunications (DECT).
The present document is based on DECT Common Interface (CI) specification ETSI EN 300 175, parts 1 [1] to 8 [8], to
enable DECT terminals to interwork in the public and private environment.
In addition, for the purpose of interoperability and wherever it is found appropriate, the present document takes into
consideration requirements specified in various DECT profiles; reference to relevant profiles is provided whenever
appropriate.
General attachment requirements are based on ETSI EN 301 406 [9].
Further details on the DECT system may be found in ETSI TR 101 178 [i.1].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
Since its introduction in the early 90s the DECT technology has enjoyed world-wide acceptance with most of the
countries accepting in full the original DECT requirements specified in the extensive DECT standards set developed
and published by ETSI (www.etsi.org). Some regions, due to specific local requirements, have used the DECT standard
and modified it to comply with those specific requirements.

In September 2004 the United States (US) Federal Communications Commission (FCC), in FCC 04-219 [11],
Sixth Report and Order, Third Memorandum Opinion and Order, and Fifth Memorandum Opinion and Order,
introduced modifications to the requirements applicable to the 1 920 MHz to 1 930 MHz Unlicensed Personal
Communications Services (UPCS) frequency band. The modification enhanced the existing rules for isochronous UPCS
operations in the 1 920 MHz to 1 930 MHz band in order to provide additional flexibility, thereby permitting the
deployment of additional unlicensed devices in the band operating on a wider variety of technologies aimed at
providing "a wide array of mobile and ancillary fixed communication services to individuals and businesses".
The present document provides the necessary requirements to allow DECT terminals deployment in the US 1 920 MHz
to 1 930 MHz UPCS frequency band in accordance to the new rules. Clause 4 provides the basic DECT protocol
reference model and indicates the affected functionality areas. Clause 5 specifies the relevant requirements. Annex A
provides information on market acceptance and product availability of DECT.

1 Scope
The present document specifies that set of technical requirements for Digital Enhanced Cordless Telecommunications
(DECT) Fixed Part (FP) and DECT Portable Part (PP) necessary for the support and provision to the user of various
multimedia services in the 1 920 MHz to 1 930 MHz Unlicensed Personal Communication Service (UPCS) frequency
band in accordance with the modifications introduced by the United States (US) Federal Communications Commission
(FCC) FCC 04-219, Sixth Report and Order, Third Memorandum Opinion and Order, and Fifth Memorandum Opinion
and Order [11].

4 DECT protocol reference model
Figure 1 shows which of the layers of the DECT protocol stack are affected by the UPCS rules. The layers 2b and above
are not affected at all.
The layer 2a (Media Access Control layer) needs only some minor additions.
The layer 1 (Physical layer) is almost identical with standard DECT. For UPCS, the carrier frequencies used are within
the band 1 920 MHz to 1 930 MHz and are broadcast by the base station. The maximum allowed transmit power is
slightly lower than in standard DECT, but can also be broadcast by the base station, as specified in ETSI
EN 300 175-3 [3] ((V1.9.1) or later).

5.0 General
This clause provides a reference and/or explicitly specifies requirements to DECT terminals/systems implementations to
satisfy the specific UPCS 1 920 MHz to 1 930 MHz FCC requirements [12].
NOTE: Test and Certification Procedures for UPCS equipment.
For FCC approval there are two main steps:
 Testing at laboratory accredited to test to ANSI C63.17 [13] and is listed by the FCC as an
approved laboratory for UPCS testing; and
 Certi
