Six cables connect the Tx UL switchbox to the IFL. Twelve cables connect the Rx UL switchbox to the IFL. Why the difference in number?
What is both paths have 3 antennas with two polarities each (3x2=6). The receive path additionally is wired with two bands for each (6x2=12).

Methodology whereby a system is continually divided into two until the fault has been isolated.
What is half-split method?

Calculate the receive L-Band frequency when an STT has 1050 MHz programmed as their transmit L-Band frequency in Band 1 Ku.
What is 1300 MHz?

This burst is responsible for an NM requesting DCOM slots from the NC.
What is Assigned Return Order Wire?

The total number of input and output ports on the TX UL switchbox.
What is 32 inputs, 16 outputs.

Possible causes of "Contention Login Failed" Protocol Status Message in HCI software.
What is a transmit issue? (HPA off, Tx chain broken, Tx chain gain value too high, Contact EIRP too low, Max EIRP too low, RTD wrong, etc)

What are the 4 fundamentals of marksmanship?
What is Steady Position, sight picture, trigger squeeze and breathing?

What is the purpose of FEC?
What is to reduce transmission errors between modems by injecting additional bits representative of the original data?

Distant end STT calls and reports their SAT light on the Linkway blinks but will not go solid? Their bootfile is good, they've peak/polled and have confirmed their tx path is good. What are something that should be checked on the RHN side?
What is they are enabled in the NMS or their GPS coordinates are accurate?

This is the main factor in determining the gain of an antenna.
What is Aperture or Size?

This field in the HCI software configures the power a modem's initial burst into the network will be sent at.
What is Contact EIRP?

If using the front panel display, what should be programmed first on the transmit side vs the receive side?
What is Input first on TX, Output first on RX?
400
Distant end STT calls and says they have solid "TX" and "RX Lock" lights on their 2050E but aren't able to pull pages from the RHN. Upon further inspection, the RHN FDMA modem does not have Rx Lock on the STT. Looking at the frequencies on the Spectrum Analyzer, you notice their carrier occupies roughly 1/10th the BW that yours does. What is a likely cause for this (long-winded) issue?
What is the Distant end has "skipped" a 0 in their transmit datarate? (Ex. Cutsheet or SAA says 512 kbps. 51200 bps is programmed in the modem when it should be 512000 bps)

This is the Protocol Status Message(s) that can be seen when a NM inputs their passphrase incorrectly and attempts to join the network.

What input does the 10th TT in each enclave run to on their respective LL TX switchbox?
What is Input 42?
500
Distant End STT calls and complains that their Linkway wasn't getting a solid SAT light so they replaced it with a spare. Now they can't get their blinking SAT light back even though they've confirmed the software version on the modem, loaded their new bootfile and kept the antenna trained on the satellite. When they run the "rx" command, they see "Confirm2" under status instead of the typical "Search" when the TDMA modem is not receiving. What is a likely culprit of this symptom?
What is S2 modems that come from Linkway by default, have their Encryption Modules enabled? Need to bypass the encryption.

Who holds the distinction of holding the highest rank in US military history?
Who is George Washington (posthumously promoted on the 4th of July 1976 to the rank of General of the Armies of the United States of America to have "such grade to have rank and precedence over all other grades of the Army, past or present")?
