Changing line modes won't really help your situation. The problem is noise in the line.
If you also have phone service (wet loop), check any filters first. If it happens often, try keeping an eye open if something you're doing coincides with the disconnect, ie., interference from another device (treadmill, AM radio, halogen lights, speakers, PSUs, etc..), or if it's windy or raining (usually it's only affected in aerial plants). Also check your modem logs if there is a pattern.
You must rule out your inside wiring first before calling your ISP to send a tech out, or else you can be charged. Hooking the modem up directly at the NID or demarcation point can also help you determine whether it's their network that's the problem, in which case you won't be charged anything.

Set Mode to G.DMT only for a line under 6Mbps.
You should not have connection drops aka disconnections with having a downstream SNR of around 16 dB. Look for interference issues or wiring issues.

SN Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. 6dB is generally the lowest dB manufactures specify in order for the modem to be able to synch. In some instances interleaving can help raise the noise margin to an acceptable level. Generally speaking, as overall bandwidth increases, your signal to noise ratio decreases. A customer that upgrades from 1.5 to 6.0 (or provisioned with the MaxSync Profile) will typically see a corresponding decrease in the signal to noise ratio. This is normal and nothing to worry about. The higher the number the better for this measurement.
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding
Important MaxSync Information: MaxSync customers will rarely have SN Margins above 20dB and should not be concerned unless it is below 9-10dB.
Measure of how much the signal has degraded between the DSLAM and the modem. Maximum signal loss recommendation is usually about 60dB. One of the biggest factors affecting line attenuation is distance from the DSLAM. Generally speaking, bigger distances mean higher attenuation. The lower the dB the better for this measurement.
20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues
