Decoding the names of derivatives

Hi guys, I am absolutely new to this stuff, so please bear with the basic question.
I trade on reliance money, and wanted to set up a market watch for options on Reliance Industries - when I searched for the ticker, there were two choices:
1) Relianceeq
2) Reliancebe

What's the difference between the two?

Thanks

The BE series was used for rolling settlement before July 2001 and is now used for T2T.

So this just means that the BE series cannot be traded intra-day? Thanks
