NOTE:
All circuits on the PSTU and RSTU cards provide off-premises station (OPS) capability. On the PESU card, only cir-
cuits 1 and 2 support OPS. PSTU/PESU cards must use OL13A or equivalent line conditioning for OPS connection.
RSTU cards must use OL13A or OL13B if providing -24 volt loop voltage; or if equipped with the -48 volt loop option
card (R48S), either OL13A, OL13B, or OL13C may be used for OPS connection.
