Downstream (Rx) Receive Power Level:
This is the amount of signal received by the modem from the transmitter in the cable company head-end.
For all modems:
-15 dBmV to +15 dBmV maximum.
-12 dBmV to +12 dBmV recommended.
0 dBmV is the "optimal" level.
Upstream (Tx) Transmit Power (a.k.a. Return Signal) level:
This is the amount of signal transmitted by the modem to reach the receiver in the cable company head-end.
+8 dBmV to +58 dBmV maximum for QPSK. (DOCSIS 1.x)
+8 dBmV to +55 dBmV maximum for 8 QAM and 16 QAM. (DOCSIS 1.x)
+8 dBmV to +54 dBmV maximum for 32 QAM and 64 QAM. (A-TDMA DOCSIS 2.0)
+8 dBmV to +53 dBmV maximum for S-CDMA DOCSIS 2.0 modulation rates.
Recommended upstream signal levels are +35 dBmV to +52 dBmV.
void main() doesn't work?
A: It has been reported that programs using void main() can crash.
Q: The book I've been using, _C Programing for the Compleat Idiot_,
always uses void main().
A: Perhaps its author counts himself among the target audience.
