Note
Standard telephones connect to circuits on the Standard Telephone Interface PCBs: RSTU, RSTU2,
RDSU/RSTS and PSTU via the MDF with standard twisted-pair jacketed telephone cable. (See single-
pair wiring in Chapter 6 – MDF PCB Wiring
The standard telephone cable's overall loop resistance, connected on- or off-premises, is 300 ohms
max. for PSTU; 600 ohms for RSTU and RDSU/RSTS with -24VDC (no R48S), and 1200 ohms for
RSTU and RDSU/RSTS with -48VDC (R48S installed on RSTU, RSTU2, or RDSU PCB), including
telephone resistance. This applies to all devices connected to standard telephone circuits.
A standard telephone connected off-premises via the telephone network should interface with OL13A,
OL13B, or OL13C lines (or equivalent) and connect to an RJ21X, FIC jack or equivalent.
