A quick question on usage details (screenshot is included)

Hey guys I'm new here. I recently changed from UL750 to Combo 500(a.k.a. Home 500C ). For the past 3 days I couldn't view my usuage details, however I was able to today.
My question is will I be charged for the 298MB under the NU column in the pic i attached?

Also in the morning around 5:30 a.m. there are frequent disconnections taking place, is this normal? It doesn't happen at any other time of the day or night

The Last column total ( less NU) if it exceeds 1536 MB ( for Home500C 1.5 GB) you have to pay.
Say this shows 1736 MB full month. less 1536 Pay for 200MB.
This month wef 3rd. so another 100 MB less.

Always ensure modem is Switched OFF at about 0155AM and 0755 AM, so that continous data usage recording is avoided.

So the "Chargeable Units" column is important to keep a track of rather than the "total volume" column and for values above 1.5GB in it is what I would have to pay for. Another thing, is the last column reliable? I know the dataone site is usually down/unstable for the first 5-7 days of the months since the billing records are taken during this time & the usage details are not consistently updated. But is the usage that it shows on the last day of the month, the final usage of the entire month?

Apart from that, regarding switching ON the modem at 2:00 a.m. I'm using Imran's Broadband Helper for it. It reboots the modem for me. I have a D-Link router (GLB-802C) which acts as a modem as well as a router but I primarily use it as a modem. I'm not instantly connected to the internet when I switch it ON (ADSL led gets connected & stays stable however), I have to dial-up(verify id & password) to get connected & be able to browse/download/upload, I use the Windows Task Scheduler to connect & disconnect at particular time intervals. The router configuration page shows that i'm using "Bridged" WAN type, however earlier when I had setup a new connection windows never showed an option for bridged interface, it was showing "PPPoE" type for DSL connections. So what type of connection is mine?
