Speed-Up Eb/N0 Range
The Speed-Up Eb/N0 Range parameter provides a means of decreasing the
power adjustment period when an excessive delta occurs between the E
b
/N
0
receive level and the target value. This ensures that an optimal receive level is
maintained.
Normally, the DPC message is sent every 30 seconds from each terminal in the
network. Should the received E
b
/N
0
level at the demodulator ever fall outside
the specified range, the terminal increases its message send rate to every 10
seconds until the receive level is again within the range set value. This provides
a speed-up loop to rapidly regain link quality.
The default value for this parameter is 3 dB.
Target IP Address
The Target IP Address identifies the modem that is transmitting to this
SLM-5650A, and will be receiving the DPC messages that provide the current
E
b
/N
0
value for this unit. Typically, all Remotes will specify the Hub modem
that is supplying the TDM outbound. The Outbound IP address is sent out to all
