WHAT IS (CAN) CUSTOMER ACCESS NETWORK ?
 
   

The line distribution network between a telephone exchange and the customer premises is called the (CAN) "customer access network". Specifically, the CAN extends from the main distribution frame (MDF) in the telephone exchange to the lead-in cable termination points (telephone sockets or building/campus distributors) in the customers' premises.

 

The CAN cables coming out of the telephone exchange are called "main" cables. Main cables may terminate in the distribution devices called 'cross-connection units (CCU's), otherwise known as the street 'cabinets' or 'pillars' you commonly see.

Some parts of the CAN maybe aerial (installed on poles), however, aerial cabling is generally confirned to distribution and lead-in cabling.
