The Ethernet services are presented in different ways depending on the link speed you have requested.
===1Gb/s (

===100Mb/s (
For 100Mbit/s links
IMPORTANT the port on the Openreach supplied unit is sometimes configured as fixed full duplex. This means that if it is connected to an un-managed switch or un-configured port on a switch, router or firewall then it will not work correctly. It will seem to work, but as soon as any reasonable level of traffic flows there will be dropped packets seriously hindering upload speeds. You must have a managed switch or port connected to the link and configure the port to be fixed full duplex 100Mbit/s for it to work correctly. We can supply a small managed switch for this purpose if you require.
==VLANs==
At the customer side the service is presented on a VLAN. The VLAN ID will be discussed during the order process. This would then be set on your router as the VLAN on interface that is connected to the Openreach NTE.
The link you have can carry one or more service - the common one being for internet access. However the same link can have internet access and site-to-site access
Where a dedicated site-to-site fibre is used then any packets simply go to the other end including any VLAN tags. This link is effectively a very long Ethernet cable, though still subject to packet size limits.
