1 Scope
This ETS specifies simple file transfer as a teleservice over the Integrated Services Digital Network
(ISDN) using File Transfer Access and Management (FTAM - EN 30607 Parts 1 to 6 [5] (incorporating the
corrigenda) and ISO/IEC 8571, Parts 1 to 5 [6]).
A basic ETS, fully compatible with the Simple File Transfer ETS as described in ISO/IEC ISP 10607 Parts
1 to 3 [1], [2], [3] & [4], the equivalent European Norm, EN 30607 [5], and in ISO TR 10000-2 is described.
Conditional extensions which cover additional ETSI requirements are also specified. An implementation
claiming full conformance to this teleservice is to support all of these conditional extensions. Basic and full
implementations may interwork, as the extensions can be negotiated out in the initialization phase. The
specification of the mapping between ISO Session Service and a Transport Service running over ISDN is
based on ETS 300 080 [13].
This ETS is presented in a number of clauses. Clauses 6 to 9 specify the FTAM specific part of the ETS
and is based on "Simple File Transfer", EN 30607, Part 3 [5]. It could become the first of a family of ETSs
for the use of FTAM over ISDN, with additional, more powerful ETSs based on ISO/IEC ISP 10607, Parts
4 to 6.
Clause 10 gives the "Specification of the ACSE, Presentation and the Session protocols for the use by
FTAM", and notes the additional constraints to EN 30607, Part 1 [5].
Clauses 11 and 12 give lower layer application rules for the Transport Service to be used based on ETS
300 080 [13]. Again it notes the additional constraints in this ETS for the support of the teleservice "File
Transfer Access and Management (FTAM) over ISDN, based on simple file transfer".
The ETS also contains three annexes. Annex A (normative) is a delta ETS Implementation Conformance
Statement Requirements List for FTAM, based on annex A of EN 30607-3 [5], the second (annex B
(informative)) is a set of recommendations on parameter combinations through the lower four layers to
achieve optimum throughput and the third (annex C (informative)), provides a bibliography of non-
normative references given in this ETS.
The ETS is, therefore, structured as follows:
Clause(s) Title
6 - 9 FTAM (this part plus the PICS);
10 ACSE, Presentation and Session;
11 - 12 Lower layers and Transport based on ETS 300 080 [13];
annexes A+B ISPICS for the FTAM specific part and lower layer parameters.
The FTAM part of the ETS is based on (and conformant to) EN 30607-3 [5] which has additional
European specific text preceding the ISO ISP text. It also, however, references ISO/IEC ISP 10607-3 [4]
for international completeness. It is also aligned with the recommendations in the CEC European
Procurement Handbook for Open Systems (EPHOS). For example, EPHOS defines that for a general
purpose system for terminal-to-terminal or to host, all four possible roles (initiator and responder, sender
and receiver) are implemented as is needed for a system claiming full conformance to the teleservice.
Basic conformance to the teleservice can be claimed for specialized systems as identified in subclause
6.1.
Additional restrictions are defined for the specific ISDN environment and these are clearly identified in
clause 9.
Some of the European Workshop for Open Systems (EWOS) conformance Abstract Test Suites (ATS)
will be selected and can be applied to the teleservice FTAM Simple File Transfer over ISDN with a few
changes and additions. This is used with ISDN specific additions for the Transport mapping.

'p' = partial support of the attribute is permitted, as defined in ISO/IEC 8571-2 [6].
5 Conformance
This ETS states requirements upon implementations to achieve FTAM simple file transfer teleservice
terminal interworking. A claim of conformance to this ETS requires that all requirements in the relevant
base standards are satisfied, and that all the requirements in the following clauses are satisfied. Clauses 9
to 12 state the relationship between these requirements and those of the base standards.
5.1 Conformance statement
For each implementation claiming conformance to this ETS, an appropriate set of PICS shall be made
available stating support or non-support of each option identified in this ETS. In addition, for an
implementation claiming basic conformance, the status of each conditional option which has not been
implemented shall be explained. An implementation claiming full conformance shall support all conditional
options.
6 FTAM Services
6.1 Classes of service
The most widely implemented Service class is the File Transfer and Management class (no file access).
This is the preferred class (as restricted in Simple File Transfer, EN 30607-3 [5]) and is the basis for the
rest of the detailed recommendations. The File Transfer Class shall also be implemented with the Limited
File Management functional unit as mandatory. All future references are to EN 30607-3 [5] which is
textually identical to ISO/IEC ISP 10607-3 [4] with the addition of a European foreword.
EN 30607 [5] allows optionality in the roles of initiator and responder, and in the ability to send or receive
files. The main requirement is for symmetric PC-to-PC and this also requires all four roles to be available.
Specialised systems, for example, file or print servers need only ever act as a Responder. Conversely,
specialised simple terminals accessing a server or a host need only ever act as an Initiator. These basic
styles of usage are common and considerably simplify implementation. In support of such usage this ETS
distinguishes between the full conformance of general purpose systems and basic conformance of
specialized systems being capable of interworking with general purpose systems.
6.2 Functional units
For the full requirements of terminal access, the Limited File Management functional unit (the ability to
read attributes such as file size, Create files and Delete files) shall be mandatory.
The Enhanced File Management functional unit (the ability to change attributes) is optional in the basic
service but mandatory in the full service. It allows the user to modify attributes of selected files such as
rename a file. This is required for an implementation claiming full conformance. However, it can also allow
the ability to change the Access control security attributes. This is not considered to be safe. Therefore,
the Security Group of Attributes should not be negotiated in conjunction with this functional unit.
FTAM allows automatic Recovery from a network failure, or even an end system or terminal system
failure. The Restart (warm recovery) and Recover (cold recover) functional units are, therefore, highly
desirable for general purpose systems and Recovery shall be mandatory for full automatic mode.

ETS 300 388: February 1995
6.3 Document types (or file types) supported
The support of the Document types FTAM-1 (unstructured text file) and FTAM-3 (unstructured binary)
shall be mandatory as specified in EN 30607-3 [5].
The Document type (file type) NBS-9, which is the definition of a Directory file, shall be mandatory in this
ETS for implementations claiming full conformance. This is to allow the ability to List Directory. The use of
this is defined in EN 30607-3 [5], clause 6.
The FTAM 2 document type (sequential or record oriented text) is optional but should be used (strongly
recommended) as it is useful for word processing and other common applications and widely
implemented. FTAM 4 (sequential binary) is outside the scope of this ETS.
INTAP-1, the Japanese document type for very large binary record files (image processing for example),
is optional in EN 30607-3 [5]. It is not useful in a terminal-to-terminal environment and is, therefore,
outside the scope of this ETS. Presentation abstract syntax for INTAP Document Type is, therefore, also
outside the scope of this ETS.
In this environment, only a simple Presentation service shall be required. The ability to perform context
management ( P-Alter-Context ) shall not be necessary. All required file/document types to be used on
this session shall be negotiated at connection time. This is sufficient for normal terminal use. This is
reflected in the Presentation Service requirements.
6.4 Attributes
The Storage group of attributes is still optional for the basic service but strongly recommended. In addition
to the requirements of EN 30607-3 [5], it shall be mandatory for implementations claiming full
conformance.
The security group of attributes are optional for the Responder. Given the problems with the ability to
change securi
