Interconnection of the E1 card of AR routers

Methods of connecting the E1 interface of an AR router to other devices using cables are described as follows:

Devices of operators provide the BNC connector in general while AR routers provide the DB9 female connector (cards with 1 interface or 2 interfaces) or the RJ45 connector (cards with 4 or 8 interfaces). The connection methods are as follows:
- BNC connectors of operators' devices -- connectors of coaxial cables -- (BNC connector on the customer end -- E1 cables -- DB9 male connectors) -- DB9 female connectors of routers
- BNC connectors of operators' devices -- connectors of coaxial cables -- (BNC connector on the customer end -- E1 cables -- RJ45 connectors) -- RJ45 connectors of routers

Cables with BNC and DB9/RJ45 connectors are used.
