Atm bridges syntax is dslX ? (On DM200 modem)

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi
I'm using openwrt on DM200 adsl/vdsl modem (ADSL mode).
I create 2 (two) ATM bridges with different VCI and different Bridge unit number but same ATM device number , now i need to bridge them with two different VLAN , what is the syntax to specify what ATM bridge to use ?
I suppose dslX.Y with X = ATM device number and Y=Bridge unit number but i cannot find documentation on Bridge unit number usage.

It might be nas0 , nas1

option nameprefix 'dsl'
