Standard Telephone Interface Unit—An optional PCB (an older version
of RSTU2) with a built-in ring generator that provides interface for eight
standard telephones or optional hardware peripherals (voice mail
devices, Background Music source, fax machines, etc.) The PSTU2
has a square wave ring generator that can be set for 190V peak-to-
peak or 130 V peak-to-peak. The PSTU2 is also used with older Strata

ISDN Basic Rate Interface (BRI) Unit—Provides two circuits, each of
which provide two simultaneous voice and/or data connections with a
single interface. BRI uses the 2B+D transmission format which is
defined as two 64-kbps bearer channels and one 16-kbps data
(control channel). Available for Strata CT.
ISDN Basic Rate Interface (BRI) Subassembly—Attaches to the
RBSU to provide two additional BRI "U" circuits that can be used to
connect to Network BRI lines and/or station-side connections only.
Available for Strata CT.
Battery cable that connects reserve power batteries to RBDB battery
distribution box (3 or more cabinet installations).
Feature Key Upgrade—Subassembly that attaches to the common
control unit to provide the system with optional features. There are
three versions of the RKYS: the RKYS2, the RKYS3 and the RKYS4,
each of which provides a distinct set of features.
Remote Maintenance Modem Subassembly—A subassembly installed
on the RSIU Optional Interface Unit that allows the system to be
connected with a remote administration/maintenance terminal or DK
Admin personal computer.
