The combined RCTUCl/Dl PCBs (Release l ) ,
(Release 3).
There are two versions of RCTUC: RCTUCI
and RCTUC3. RCTUCI can be used with
with RCTUD 1, 02 and 03.
Each of these units supports a distinct number of
cabinets, stations, and lines. The RCTUA (1 and 3)
PCB can support only one cabinet, and up to 32
stations or 16 CO lines. The RCTUB1, RCTUB2, and
and up to 80 stations or 48 CO lines. The
operate together to support up to six cabinets, and up
to 240 stations or 144 CO lines.
Additionally, each of the common control units can
support a separate set of features. Refer to
Chapter I-Configuration for more common control
unit capacity and feature information.

Each the common control units (except RCTU BB)
may be equipped with an RRCS (4, 8, or 12) to
interpret Dual-Tone Multi-Frequency (DTMF) signals
transmitted from tie/DID lines and standard telephone
ports. The common control units also provide an
interface (along with a volume control) for a Music-on-
hold (MOH)/Background Music (BGM) source.
RCTU controls, indicators, and interface connectors
are shown in Figure 4-4 through 4-14 and described in
Table 4-1 through 4-1 1.

There are three RRCSs: the RRCS-4 has four DTMF
receiver circuits; the RRCS-8 has eight receiver
circuits; and the RRCS-12 has 12 receiver circuits.
The RCTUAI and RCTUA3 can support up to 12
DTMF receiver circuits; the RCTUB, RCTUB2, and
RCTUBA have up to 12 circuits; and the
