Single Channel Per Sample Clauses

Single Channel Per. Carrier (SCPC) Traffic ----------------------------------------- Special considerations must be observed for SCPC traffic in addition to those contained in the access procedures in Paragraph 9. Since a large number of carriers share the available bandwidth and power of the transponder, any change to assigned allocations can affect all traffic in the transponder. When an order is accepted by GE Americom for SCPC service, the allowable power and bandwidth that may be used by the customer is precisely specified. It is very important that SCPC power level, center frequency and deviation must not be made by the user without coordination with GE Americom's TOC. Uncoordinated adjustment of carrier parameters can cause interference and degradation of service to other communications in the transponder. Some customers are given a percent of total transponder power and bandwidth or are assigned a specific power level to be used within a specific frequency range. These customers are responsible for insuring that their individual carriers do not exceed their contracted allocations or cause interference to other customers. GE Americom will conduct sweeps of the transponder to check power and bandwidth assignments. As an aid to setting and checking SCPC power levels, there are 10 dBW unimodulated reference carriers transmitted by GE Americom on the following transponders with their respective frequencies: Transmit Receive -------- ------- Satcom K-1, transponder 1 14012.20 MHz 11712.20 MHz Satcom K-2, transponder 2 14058.55 MHz 11758.55 MHz Satcom C-5, transponder 3 5985.00 MHz 3760.00 MHz Satcom C-5, transponder 21 6346.00 MHz 4121.00 MHz When using these reference carriers for comparison, the carrier under test must be unmodulated.

Single Channel Per. CARRIER (SCPC) TRAFFIC ----------------------------------------- Special considerations must be observed for SCPC traffic, in addition to those contained in Section 7 above. Since SCPC carriers share the available bandwidth and power of the transponder, any change to assigned allocations can affect all traffic within the transponder. When an order is accepted by GECEL for SCPC service, the allowable power and bandwidth that may be used by the customer is precisely specified. It is very important that SCPC power level, center frequency and carrier bandwidth be initially adjusted while being monitored and under the direction of the TCC. The user may not, without prior coordination with GECEL and the TCC, make any modifications to their SCPC power, center frequency or bandwidth. Uncoordinated variation of carrier parameters can cause interference and degradation of service to other carriers within the transponder. Some customers are allocated a percent of total transponder power and bandwidth or assigned a specific power level to be used within a specific frequency range. These customers must submit and maintain traffic plans to GECEL and the TCC summarizing their proposed operations within the allocated space segment. These customers will be responsible for assuring that their individual carriers do not exceed their contracted allocations or cause interference into other customers. The Satellite's transponders will be monitored continuously to verify SCPC power and bandwidth assignments.
