Dear Mr. Howden:

        The following information is being submitted in response to your September 3,
2004 letter with respect to the three above-referenced pending satellite earth station
applications. For ease of reference, your comments are included in the order in which
they appeared in your letter, followed by our responses which include corrected and
clarified information.

       First FCC Staff Comment:

         Intelsat 511, 603 and 605 requested as Points of Communications by Telco 214
are not at the locations specified in the application. Specifically, Intelsat 511 is no longer
operational, Intelsat 603 is currently located at 340 E.L., not at 335.5 E. L., and Intelsat
605 s at 33 E.L., not at 332.5 E.L. Consequently, we are not able to determine the
satellites with which Telcon 214 seeks to communicate. If Telco 214 re- files, it must
accurately identify the satellites with which it seeks to communicate, the orbit location at
which they are operating or are authorized if not yet launched, and the frequency bands in
which operations to and from each satellite will occur.




                                          Page 1 of 4


       Telco 214 Response:

         Telco 214 clarifies that in its intended bands of operation (3700 to 4200 MHz for
the downlink and 5925 to 6425 MHz for the uplink) ALSAT operation, if the applications
are approved by the Commission for routine authorization, would automatically be
inclusive of all Intelsat satellites within the approved arcs of the respective antennas. It is
such operation that Telco 214 requests. Intelsat 511 is no longer operational and
therefore is not being requested as a point of communication. Further, Telco 214 clarifies
that it does not intend to utilize Intelsat 603. Rather, it intends to communicate with
Intelsat 905 (located at 335.5 E.L.). Neither does Telco 214 intend to use Intelsat 605.
To summarize: In view of the fact that Telco 214 is herein modifying its three subject
applications to qualify for routine processing, ALSAT operation will include all
reachable Intelsat satellites. Accordingly, ALSAT operation is respectfully requested for
all Intelsat satellites within the requested operational arcs of the Telco 214 earth stations
as well as all other satellites licensable under the ALSAT designation and located within
the proposed operational arcs of the three subject applications.

       Second FCC Staff Comment:

         For application SES-LIC-20040528-00747 [Universal 13 Meter], the EIRP
density of 56.8 dBW/4KHz entered into for the emissions 2M46G7W and 205KG7W in
Item E49 of Schedule B, with gain of 56.8 for the antenna, results in an input power
density of 0.0 dBW /4KHz, which exceeds the criteria for routine authorization for digital
signals for the proposed transmit band 5925 to 6425 MHz. For application SES -LIC-
20040528-00748 [Andrew 9.1], the EIRP density of 53.9 dBW/4KHz entered for the
emissions 2M46G7W and 205KG7W in Item E49 of Schedule B, with gain of 53.9 for
the antenna, results in an input power density of 0.0 dBW/4KHz which exceeds the
criteria for routine authorization. Also, the emission 2M46G7W shows an eirp of 81.8
dBW, which is greater than possible with the stated maximum input power of 200 watts,
or 23.01 dBW, and gain of 53.9. For application SES-LIC-20040528-00749 [Vertex
9.0], the EIRP density of 53.9 dBW/4KHz entered into for the emissions 2M46G7W and
205KG7W in Item E49 of Schedule B, with gain of 53.5 for the antenna, results in an
input power density of 0.4 dBW/4KHz, which exceeds the criteria for routine
authorization. To allow us to continue with review of these applications, you will need to
either (1) amend the values for eirp density or other variables to values that meet criteria
for routine authorization or (2) provide data in the form of charts or tables that clearly
show that the off axis eirp that would result from an operation conforming to our criteria
for routine authorization, or (3) obtain affidavits from operators of satellites adjacent to
the points of communication for your proposed operation stating that those operators are
aware of the particulars of the proposed operation and have no objection. In any case,
you will need to insure that all data provided is consistent.

       Telco 214 Response:

        Telco 214 hereby modifies its previously stated values for eirp density or other
variables to values that meet criteria for routine authorization, as follows:

       Third FCC Staff Comment :

         We also note that for the frequency bands listed, 3700 to 4200 MHz for the
downlink and 5935 to 6425 MHz for the uplink, ALSAT would include Satmex 5,
Solidaridad 2, and all Intelsat satellites, and that, if the values for eirp and eirp density
result in power density conforming to our criteria for routine authorization, then ALSAT
is permissible for points of communications, but not otherwise.

       Telco 214 Response:

        The foregoing Telco 214 clarifications result in the three subject applications
being subject to routine authorization. For that reason, ALSAT authority is respectfully
sought.
