Network configuration 39
Network configuration
Set up the system clock
1 Specify the system reference clock by entering one of the following commands:
CLK:L for looping the network receive timing
CLK:I for using the IDSU internal oscillator
Always use the loop timing option if the network receive signal supplies timing.
There should only be one timing source in the T3 or E3 circuit.
The default is loop timing.
Specify the network type and framing
2 Specify your network type and framing as one of the following. The type and
framing must match your network signal.
NM13 for T3 M13 framing
NCBT for T3 C-Bit Parity framing
NE3 for E3 framing
The default is T3 M13.
Specify transmit output level
3
Set the transmit output level as follows:
NLO for cabling distances less than 450 feet
NHI for cabling distances of 450 feet or greater
The default is NLO (no amplification).
Specify transmit line build out (T3 only)
4 Set the transmit line build out as follows:
LBO:IN for cabling distances less than 225 feet
LBO:OUT for cabling distances of 225 feet or greater
The default is LBO:OUT (no line build out)
You can only set this parameter if the network is set to T3; E3 line build out is always
set to out.
