Hi Ibrahim,

It all depends upon the customer infrastructure which is looking for AToM Services.

>If Customer Infrastructure has WAN facing link mix of multiple technologies like Ethernet, PPP, HDLC, ATM, FR etc, it will require Interworking AToM Service from ISP. Please note it can provide you only Point-to-Point links.

>If customer infrastructure is using only Ethernet on WAN Access side then Ethernet mode L2VPN services will be the solution.

>If customer is sending VLAN tagged traffic, in that case VC Type-4 will be required which is again VLAN Mode service.

You can refer below link to get clarity on Type-4/5 VC
