Zhone 5620 インストール手順

When a POTS splitter is used at both ends of the local loop, wiring is connected:

From the demarcation point to the CP POTS splitter, and

From the demarcation point to the DSL jack.

— End-user system is used to represent any PC with an Ethernet connection and

DSL-based service.

— Network Service Provider (NSP) is used to represent any Internet Service

Provider (ISP) or remote LAN access provider.

When the 5620 RTU is installed without a POTS splitter, a second telephone wiring pair
is needed for DSL access.
