that Administrations should use Tables\ 1/F.64 or\ 2/F.64

Administrations should aim for full availability of
circuits on intercontinental and ARQ radio routes operated with signalling
in accordance with Recommendations\ U.1, U.11, U.12 and\ U.20. Where an

service) it is desired to obtain values for offered traffic in
erlangs, these may be determined by adding the respective values
of lost traffic to the figures for carried traffic in Table\ 1/F.64.
.PP
1.2
Table\ 1/F.64 is directly applicable only to
full\(hyavailability groups of circuits
that are operated either wholly as bothway circuits,
or wholly as undirectional circuits.
.sp 9p

.PP
1.3
Table\ 2/F.64 shows values for traffic offered in the automatic
service and is directly applicable to full\(hyavailability groups
and groups with availabilities between 10\ and\ 50.
.LP
Given the traffic offered\ (A) in erlangs and the availability
(K), the number of circuits required to provide a loss
probability\ (B) of\ 0.02 may be determined from Table\ 2/F.64.
Groups of up to 200 circuits and availabilities of 10, 20, 30,
50\ and N\ circuits (N\ circuits corresponding to full availability)
are covered. The method of applying the table is shown in
Figure\ 1/F.64.
.PP
1.4
Where groups of circuits are divided into bothway and
unidirectional components, the division and number of circuits in
each component will be agreed between Administrations.
