Our Metro access network is built using a unique "2 POP" design. Our Toronto network has 2 major metro Points of Presence (POPs), on opposite sides of the city. Each of these POPs can operate independently, and are fully capable of running the entire city by themselves. There are a minimum of 2 high-count fibre-optic cable routes between these two POPs that wind their way through the city, never crossing each other, and provide connectivity to buildings along their route. Each building is connected to both of these POPs, with active equipment in each building maintaining a relationship with both at all times. If a connection goes down, or an entire POP is lost, the traffic is automatically re-routed to the other POP where it is processed and sent on to its final destination. This all happens without the customer noticing that anything happened.
