      Re: How does LLU Work?

      Hello again,

      I've moved this post to start a new thread as the discussion was in danger of hijacking someone else's thread.

      Ok, so keeping things simple here is a simple guide to how LLU works:

      <The Internet> -> ISP Servers -> Backhaul network -> Main Exchange -> Local Backhaul -> Satellite Exchange

      In both the main exchange Sky will have their own Kit. In addition Sky may also have their kit in the smaller satellite exchange.

      Exchange -> BTO Green Street Cabinet (where used) -> Home

      The final leg uses that same local infrastructure which is maintained by BTO. Since this is the part which will affect the connection speed, the same rules for diagnosing faults and getting them fixed will apply, but it is important to know whom to contact.

      Since the person whom you are paying the line rental to is responsible for contacting BTO to get any repairs completed, it might be necessary to call BT Retail or Sky. So it is important to understand that a broadband fault might not be the responsibility of Sky if someone has their line rental with BT Retail.

      Sky have the ability to access and control remotely their LLU kit in each exchange. This means that they can adjust the connection speed manually for a specific connection or trigger DLM to adjust it automatically.

      As for contacting BT Wholesale, you and I as customers of an ISP must NEVER attempt to contact BTW. Sky is a customer of BTW and it is they, not you or I who contacts them if required. With this in mind Sky will need to liaise with BTW where a customer has Sky Broadband Connect as this is a BTW re-badged product. Connect is only provided where Sky doesn't have their LLU kit in an exchange or all the connections on their kit are full. However if FTTC is available Sky can provide SFU or SFUP provided the main exchange has Sky's LLU kit.
