one PDKU circuit (See Paragraph 4.20 for digital
telephonewiring information and Section 200-096-
208 for instructions on how to connect peripheral
devices to PDIU-Dls).

standard twisted-pair jacketed telephone cable.
Single-pair wiring is sufficient, unless the system
must operate on reserve power. In this case, two-
pair wiring should be used (see Section 200-096-
208for more wiring information and instructions on
how to connect peripheral devices to PDIU-DSs).
