Distributor and consumer terminals are connected by the service mains. A distributor is an intermediary entity between the product producer and another entity in the supply chain or distribution channels, like a retailer, a system integrator (SI) or a value-added reseller (VAR). The distributor performs some of the same functions that a wholesaler does but generally takes a more active role.
