Description: Relevant only for T1 ISDN NFAS trunks indicates the group number of the NFAS group. ;Valid NFAS group numbers are only 1 to 4, 0 indicating that this trunk is not NFAS (in this case the ISDNNFASInterfaceID and DchConfig parameters are ignored).

What is acIsdnNfasGroupNumber?

This integer (0-4) identifies which NFAS group a T1 ISDN trunk belongs to for coordinated multi-trunk operation. Setting it to 1-4 enables NFAS (NFAS) bonding; 0 disables NFAS for standalone trunks. Example: value 2 groups this trunk with others in NFAS group 2 for load balancing.
