ATM link with OAM + AAL5 + ABR

[Texugo Gundum]

Hello gurus, 

    I've a small and simple setup to deploy here and beside the excellent 
    FBSD documentation I didn't found a way so I'm asking for a help. 
    A ForeRunner HE 155 will be pluged (in SDH) into a Ascend switch
    signalling UNI 3.1 and talking ABR QoS (PCR=23584cps). 
    We will need to talk to a Cisco router also with AAL5 and OAM 
    management cells. 

    Is there a way to make it work with FreeBSD ? 

    Thanks !
