Hi Phillip

On the SP end, its delivered on a vlan per customer. (double tagged).

You will see the customer VLANS looking something like this.

SVID 14, CVID 130

Another customer on the same ISAM will show up SVID 14, CVID 145. This assumes the customer is using PPPoE/DHCP on PVC 0/110

The SVID, CVIDs are unique per handover. However if you aggregate your handovers into one port, you will have clashes.

If the customer is using PPPoA  on PVC 0/100, then you need to add 1600 to the CVID. The SP end will show up as PPPoE. The ISAM does the translation for you.

I’m hoping someone can clarify my understanding of this Telecom Wholesale product.

>From the Telecom wholesale web site I can see that each customer is delivered on a separate VLAN.  What I’m not sure about is the encapsulation of the data being presented form the client.

At the SP end, do they then need to provide a PPP layer (so effectively the VLAN replaces L2TP), or is it delivered ready for you to process like any “standard” VLAN circuit (aka, just needs L3 configuration added)?
