Select the line type for your model. Line type means how many wires you want to use on the CopperLink con-
nection. For example, you can select 2-wire, 4-wire or 8-wire line type for the 8-wire model.

TCPAM Type
TCPAM (Trellis Coded Pulse Amplitude Modulation) is the standard used for line coding. Select the TCPAM
type. Auto is the default option for TCPAM.

Maximum Main Rate
Select the line rate for your model. The main rate is the multiple of 64kbps, 128kbps, or 256kpbs- depending
on your model type. Use

to determine the best main rate for your model.
SNR Margin
SNR margin is an index of line connection quality. Generally, you won’t need to change the SNR Margin. You
can view the actual SNR margin in status command menu.You will experience better line connection quality
for larger SNR margin values.

for larger SNR margin values.
For example, if you set the SNR margin ias 5, the line connection will drop and reconnect when the SNR mar-
gin is lower than 5. On the other hand, the device will reduce the line rate and reconnect for better line con-
nection quality. You may select the SNR margin from the range -10 to 21.
