Also consider O2/Be wholesale. Don't forget that in sparsely populated areas the only option may be 20CN (i.e. the exchange hasn't been upgraded) which means you need to commit to IPstream connect bandwidth on your WBMC link(s) as well as WBC/21CN. IPSC bandwidth is hideously expensive :s > The LNS would terminate both internet and private network subscribers, > so would have a dual purpose.

Dropping a customer into a VRF is usually pretty simple on most platforms. Unless you have a small number of VRFs using MPLS is certainly easier than bringing each VRF out onto its own .1q subint on each LNS (i.e. VRF-lite). Alternatively you could session steer or L2TP tunnel switch to a customer's own dedicated LNS (which could be Cisco/Linux/FreeBSD on physical hardware or a virtual machine). You mention PPPoE and unbundling, presumably then you want something that will act as both an LNS for terminating from telcos and PPPoE concentrator for direct connection to a DSLAM? We looked at unbundling some local exchanges a few years ago (with a view to taking FTTC GEA direct from Openreach where available) but the numbers simply didn't stack up. Rich.
