\fB1\fR \fBIntroduction\fR
.sp 1P
.RT
.PP
1.1
Under the provisions of Recommendations D.42, D.67
and\ D.170, Administrations engage in international accounting for telephone,
telegram and telex traffic handled each month.
.sp 9p
.RT
.PP
1.2
A growing number of Administrations are processing this monthly
international accounting data using computer based accounting systems.
Information is drawn from traffic history tapes or manually encoded from
data such as inward international accounts and statistical summaries
prepared by manual abstraction from copies of telegrams and telephone and
telex tickets.
.PP
1.3
It is usual at present to complete computer processing by
producing conventional printed accounts following the specifications described
in the various accounting Recommendations (D.42 for telegram; D.67 for
telex; D.170 for telephone). Where the receiving Administration also uses
computer
facilities, however, this information has to be re\(hyencoded for processing
through its system.
.PP
1.4
Transmission of data in encoded form avoids the
decoding/re\(hyencoding step. It also offers a faster transfer of information
than by printed forms through the mail. The latter remains true even if
the forwarding Administration has prepared the data by manual/mechanical
means.
.LP
\fB2\fR \fBAim\fR
.sp 1P
.RT
.PP
2.1
The aim of this Recommendation is:
.sp 1P
.RT
.PP
2.1.1
to enable Administrations using computer based accounting
systems to transfer information to each other in encoded form, without
the need for decoding into conventional printed form and subsequent encoding
into
machine\(hyreadable form;
.sp 9p
.RT
.PP
2.1.2
to enable other Administrations, if they so desire, to benefit
from the greater efficiency of speedier transfer of information to them
and to prepare themselves for the introduction of computer working by introducing
transmission of data in encoded form in advance of installation of a
computer.
.bp
.PP
2.1.3
to facilitate provision of printed output from computer based
systems in a format suitable for manual/mechanical processing where it
is to be forwarded to Administrations not using computer facilities;
.PP
2.1.4
to facilitate provision of printed output from manual/mechanical accounting
systems in a format suitable for data encoding where it is to be
forwarded to Administrations employing computer processing.
.LP
\fB3\fR \fBMethod\fR
.sp 1P
.RT
.sp 2P
.LP
3.1
\fIData record\fR
.sp 1P
.RT
.PP
3.1.1
The aim of this Recommendation can be met by use of a standard data record
format for the various elements of information to be transferred. The information
elements and their sequence must be compatible with the
provisions of the various accounting Recommendations so that decoding to and
encoding from printed output for exchange of information with Administrations
using manual/mechanical systems will be as simple as possible.
.sp 9p
.RT
.PP
3.1.2
Between Administrations operating computer based accounting
systems, adherence to the standard data record format for data transmission
purposes will ensure that only one interface programme will be needed to
enable any one computer installation to generate suitable input for, and
accept output from, other computer installations.
.sp 2P
.LP
3.2
\fIData transfer\fR
.sp 1P
.RT
.PP
3.2.1
Procedures already exist for transfer of data in conventional (printed)
form through the mails. Data in encoded form could be transferred by mailing
of magnetic or paper tapes, paper tape transmission by telex or data
transmission over circuits utilized for this purpose.
.sp 9p
.RT
.PP
3.2.2
While mailing of tapes avoids the encoding task for the receiving Administration
there can be delays and loss in transit. In addition, there can be difficulties
caused by the fragility of paper tape and incompatability of
various forms of magnetic tape recording.
.PP
3.2.3
Transfer of data via the telex service using paper tape
transmission and reception can be advantageous for Administrations whether
they have computer based accounting systems or manual/mechanical systems.
As both
page copy and punched paper tape can be generated at the receiving point
users of either type of accounting system can benefit. Page copy can be
used for
checking paper tape, with the latter becoming input to a computer. Page copy
can also be used as the incoming international account avoiding the need for
use of the postal service.
.PP
3.2.4
Where large volumes of data are to be exchanged, transmission over higher
speed circuits offers significant benefits. Where suitable data links
are in use for service transmissions these could be utilized. Data terminals
and modems capable of transmission speeds in the range 600 to 2400\ bits per
second should be sufficient but higher speeds could be used. For
manual/mechanical systems data received on data terminals can be reproduced
as page copy representing an incoming international account. For computer
based
accounting systems data transmission offers the possibility of complete
automation of the process by computer\(hyto\(hycomputer transfer.
.LP
\fB4\fR \fBSpecific recommendations\fR
.sp 1P

.PP
4.1
It is recommended that:
.sp 1P

.PP
4.1.1
where possible data transferred in printed form should be
placed in the order shown in \(sc\ A.2;
.bp
.sp 9p
.RT
.PP
4.1.2
for transfer of data in encoded form, the standard data
record format detailed in Annex\ A should be followed;

4.1.3
transmission of data in encoded form should be by the following
means:
.LP
a)
use of the telex system;
.LP
b)
use of data transmission over telephone circuits,
dedicated telegraph circuits or special data links;
.PP
4.1.4
transmission speeds, operating practices and technical
standards should be agreed between the Administrations concerned and should
conform with the appropriate CCITT\ Recommendations.
.sp 2P
.LP
\fB5\fR \fBCode maintenance\fR
.sp 1P

These charges should in principle be determined on the basis of
the network resources and any additional functions required to provide the

Bearer services provide for information transfer between ISDN
access points. They are characterized by a set of low layer attributes
including information transfer and access attributes depicting the bearer
capability associated with each bearer service, and general attributes. The
attribute method of characterizing services is described in
Recommendation\ I.130.
.PP
Teleservices provide the full capability for communication by means of
terminal equipment functions and network functions and possibly functions
provided by dedicated centres. Teleservices are characterized by the low
layer attributes used to describe bearer services, and a set of high level
attributes. The high level attributes generally relate to the functions and
protocols of layers\ 4 to\ 7 of the Open Systems Interconnection (OSI) model.

Supplementary services modify or supplement bearer services and
teleservices. They cannot be offered as stand alone services and must be
offered in association with bearer services or teleservices.

that although STP facilities are likely to be limited initially, as use
of SS\ No.\ 7 grows, it is likely to become a common and
important feature both for primary and reserve signalling;

that use of STPs will increase network reliability and resilience, and
enable the advantages offered by common channel
signalling to be fully realized. Accounting should therefore be
on as simple and reasonable basis as possible, so as not to
discourage STP working;

that the ISDN offers the capability of
non\(hytraffic\(hyrelated information transfer, and user\(hyto\(hyuser
information
transfer, which could be expected to have considerable impact on the signalling
network in general, and the STP in particular, and therefore may in the
longer term justify a more precise method of accounting;

purposes, but also for route dimensioning and STP capacity purposes.

on a flat rate basis. The level of remuneration will be determined by the
STP provider, on the basis of an apportionment of the various cost elements;
.sp 9p

that where STP facilities are provided by Administrations on a reciprocal
basis including temporary routing via STP facilities, for example in the
case of network failure, Administrations may bilaterally agree to dispense

\fB3\fR
that as the usage of STP facilities increases, and experience of the pattern
of traffic over the signalling system is gained, a requirement to account

The present Recommendation deals only with user\(hyto\(hyuser information
exchanged over the signalling channel in association with a communication
on
the information channel [B\(hychannel(s)]. The question of the offering of
services on the signalling channel independently of the use of the information
channel is for further study.

.PP
1.1
User\(hyto\(hyuser information exchanged over the signalling channel
during call set\(hyup and clear down as well as during clear set\(hyup
only, should be charged by one of the following methods:
.LP
a)
by inclusion in the subscription or rental charges raised
against customers;
.LP
b)
by setting an appropriate minimum call charge for
communications originated over the information channel;
.LP
c)
by a per call fee
.FS
In principle, this charge should not apply to unsuccessful call attempts
due to congestion or a
fault in the Administration's equipment.
.FE
(for further
study);
.LP
d)
when appropriate, by a combination of methods a) and b)
or a) and\ c) above;
.LP
The determination of the volume unit is for further study. One
simple solution would be to charge for the number of user\(hyto\(hyuser data
blocks exchanged.
.FE
In practice, the introduction of a charge will be determined by the extent
to which user\(hyto\(hyuser information actually will be exchanged, and
initially at least, Administrations may deem the facility to be covered by
the normal bearer service or teleservice charges, or by the subscription
or rental charges raised against customers.
.FE
e)
for the user\(hyto\(hyuser information exchanged during call
set\(hyup it may also be appropriate to charge according to the
volume of information exchanged.

User\(hyto\(hyuser information exchanged over the signalling channel

be charged according to the volume of information (data) exchanged over
the signalling channel.

2.1
To minimise the costs associated with recording and processing, it is desirable
that the traffic units used for accounting purposes should be compatible
with those used for customer charging.
.sp 9p
.RT
.PP
2.2
User\(hyto\(hyuser information exchanged over the signalling channel
during call set\(hyup and clear down or during set\(hyup only should be
accounted for by one of the following methods to be agreed between Administrations,
as a
supplement to the normal accounting rates for the bearer service, or
teleservice, with which the user\(hyto\(hyuser information supplementary
service
is associated:
.LP
a)
a monthly flat rate (for further study),
.LP
b)
a per call rate.
.PP
2.3
User\(hyto\(hyuser information exchanged over the signalling channel
while the associated bearer service or teleservice communication is in
progress should, in principle, be accounted for according to the volume
of information exchanged over the signalling channel. Alternatively, Administrations
may agree to adopt the method\ 2.2 | ) or\ b) above for this category of
user\(hyto\(hyuser
information.
.PP
2.4
The accounting rate established by agreement between
Administrations should be divided into terminal shares and, when appropriate,
into transit shares.

2.5
Administrations may bilaterally agree not to account for
user\(hyto\(hyuser information service (or mode).
