decrease – different

(PRESS RELEASE) – Recent emotional statement of General Director of
ArmenTel Mr. Klimko, publicized on the website of one of the agencies,
on Friday 25/12/2009, confirms that Mr. Klimko still did not
understand the most important thing: ADC has no obligation to ArmenTel
in terms of mirroring international resources.

Nevertheless, assuming that the Mr. Klimko is in unintentional
confusion, and being interested in the awareness of market
participants and the public, ADC is committed to provide all
interested parties a comprehensive technical explanation with
illustrations.

Let us mention that ADC does not limit the bandwidth of the exchange
channel between the networks of our companies. The service of
mirroring international resources was simply turned off at the time of
the work to re-equipment the network of ADC. Switching off the
mirroring resources has been made in the best interests of the other
operators, otherwise the users of these operators would experience
inconvenience because of periodic interruptions of access to mirroring
resources during the re-equipment period.

Switching off the mirroring resources in no way limits access to
resources by users of any operator, since in the absence of mirrors
the original resources become available through international channels
of communication of the operator.

As it is clear from the illustration, that ArmenTel users had access
to the mirroring resources through the exchange channel of
communication between networks of ADC and ArmenTel. The bandwidth of
the exchange channel is 100Mb/s, utilization of the same channel at
the time was 97 Mb/s. As it is obvious from the illustration, users of
ArmenTel used mirroring resources.

It is also quite clear from the second illustration, that after the
switching off the mirroring resources, the same users were
automatically redirected to the main resources available in the
Internet. This access to the resources is already provided by
international communication channels of ArmenTel, to which our company
has nothing to do. As it is clearly visible in the same illustration,
the bandwidth of the exchange channel between our two companies still
is 100Mb/s but utilization is already 4Mb/s, which is quite natural,
since users of ArmenTel were no longer using mirroring resource and
thus do not load exchange channel.

We consider it necessary with regards to the statement of Mr. Klimko,
where he says – «ADC in fact recognized that the bandwidth of the
exchange channel between our two companies was limited, as I said at
the press conference. Moreover, we have shown in the chart, how it
happened, so it is impossible to deny that», to re-reiterate that this
has nothing to do with reality and may be justified in the best case
that the Director of ArmenTel was incorrectly informed by his own
staff. There is a fundamental difference between the limited bandwidth
of the exchange channel and natural decrease of the load of exchange
channel. If the General Director of ArmenTel at the press conference
shows to the journalists the decrease of the exchange channel, it does
not mean that the bandwidth of the channel was limited. He is either
very misled, or attempts to mislead the public.

The question remains: why users of ArmenTel had difficulties in
accessing main resources through international communication channels
of ArmenTel?

With the continuing interest of the public we announce that works to
refurbish a network are finished and service of mirroring
international resources as of yesterday has been activated, so if he
ArmenTel not limited the bandwidth of the exchange channel, then load
exchange channel will naturally increase and reach its maximum already
during the second half of the day.

P.S. Despite the fact that the above material was successfully tested
from the number of target audiences including housewives, ADC as a
socially responsible company that cares about its reputation, declares
its readiness and invites the Director of ArmenTel at any convenient
time to conduct a logical debate on the television to reveal the truth
regarding this issue.
