DFXS Interface connections
The subscriber interface connects the terminal to the customer's 2 wire
telephone via a 2 wire line.
Each 2 wire channel has two access points: one connects to a customer; the
other is a local test port.
Warning: If there is a power failure at either terminal, any
telephone connected at the DFXS will not operate.
Please ensure that a separate telephone that is not
dependent on local power is available for use in an
emergency.
