The three-storey switchboard park programme for gateways

- Retard the gateways, simplify the route.

The three-storey switchboards are made on the assembly floor to make VLAN interroute and gateways, which are concentrated by meters and efficiently relayed. After consolidation, care is taken to keep the gateway redundant: back up with VRRP, etc., and single downfall terminals are not “not found”.
