Openreach Network

Just out of curiosity I was wondering what makes the Openreach network invisible to the end users when doing a tracert?

First hop on a trace route is your router, then next its your isp's gateway. Obviously the data must be routed through various switches in the openreach network to get from you to your isp, but you dont see any trace of it.

The GEA network (FTTC and FTTP) is essentially a Layer 2 network from the ONT in the case of FTTP right through until it gets handed off from the L2S/OLT - that’s the strict limit of the Openreach network.

Think of it as a very long Ethernet cable from the box in your house/business to the switch port in the parent / headend exchange where your ISP has their own backhaul connection to their network (or gets backhaul from that parent exchange to their core network from an intermediate provider like BT Wholesale or TalkTalk etc)

In reply to a post by Ripley:

The data is encapsulated inside your router (the PPP stuff) and that parcel is opened at your ISP end.

thanks both for the information
