TCPAM Type

TCPAM (Trellis Coded Pulse Amplitude Modulation) is the standard used for line coding. Select the TCPAM type from the drop-down list. Auto is the default option for TCPAM. You can also manually set the TCPAM type.

Main Rate

Select the DSL rate for your model from the Main Rate drop-down list. The main rate is the multiple of 64kbps, 128kbps, or 256kpbs- depending on your model type. Use Table 8 to determine the best main rate for your model.

Table 8. Main Rate Chart

Model Type	Multiple	TCPAM-16	TCPAM-32	TCPAM-64
		= 3–60	= 12–89	= 90–177
2-wire model	64	192–3840	768–5696	5760-11328
4-wire model	128	384–7680	1536–11392	11520-22656
8-wire model	256	768–15360	3072–22784	23040-45312

SNR Margin

Select the desired SNR Margin value from the drop-down list. SNR margin is an index of line connection quality. You can see the actual SNR margin in STATUS. You will experience better line connection quality for larger SNR margin values.

For example, if you set the SNR margin is 5, the DSL 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.

Line Probe

For adaptive mode applications, set the Line Probe to Enable. The Model 3202 will adapt the data rate accord- ing to the line status. The screen will prompt the parameters that will be written in NVRAM. Check the parameters before writing in NVRAM.

For all other applications, set the Line Probe to Disable.

Click Restart to reboot the Model 3202 with the new settings. Click Continue to configure other options.
