Four-Station
Interface PCB
The B-STU-D PCB (P/N 15181) serves as an interface
between the KSU and single line telephones. The
B-STU-D may be installed in any B-STU slot except the
first one.
Since the B-STU-D is required for OPX and DISA use,
it is also called the OPX/DISA Interface PCB. The
B-STU-D PCB can be used with either DTMF or dial pulse
type telephones,but DISA lines must be DTMF type
lines.
The maximum number of B-STU-D  that can be
installed in a system is as follows:
SystemMaximum
BUSINESSCOM PLUS 24
3
BUSINESSCOM PLUS 364
BUSINESSCOM PLUS 648
The B-STU-D PCB provides:
0Interface circuitry for four single line stations
0Control of the ringing signal provided by an
external ring
0 for secondary lightning protection
0An OPX circuit that can be accessed either by tip
and ring or assigned by programming 
as a dial-in
station for DISA
0Crosspoint matrix for 12 lines, six intercom ports,
and six page ports
0Ten option straps for OPX/DISA and internal or
external battery
Multi-Frequency
Receiver Unit PCB
(B-MFRU-B)
The B-MFRU-B PCB (P/N  is a receiver daughter
board for the B-STU-D or the 
 PCB. The 
MFRU-B provides interface circuits to detect and
decode DTMF signals from a single line or dial-in
 line.
One B-MFRU-B PCB is required to accept DTMF from each
single line (2500 type) telephone 
or DISA port.
Four-Station
Interface PCB
The B-STU-G PCB (P/N 15126) is similar to the B-STU-A
PCB.In addition, it is compatible with Busy Lamp
Field 
 telephones.

and a negative impedance circuit to compensate for
losses on the line.
0Four  for secondary lightning protection
The B-COU-B PCB (P/N 
 is similar to the B-COU-A
PCB,but it provides interface circuitry for only two
 lines.
This PCB serves the first two of four
CO circuits.
Line Expansion PCB
(B-XPU-A)
The B-XPU-A PCB (P/N 15360) is needed for BUSINESSCOM
PLUS 64 systems only. I t  provides crosspoints for
lines 13 through 24 and 32 stations.

Door Chime Box
Interface PCB
(B-DDU-A)
External Music
Interface PCB
(B-HBU-A)
The first expansion PCB is required for access to
lines 13 through 24 from the first 32 ports. A second
Expansion PCB is required for access to lines 13
through 24 from ports 33 through 64.
The B-DDU-A PCB (P/N 
 provides an interface
for:
0Two Door Chime Boxes (P/N 15040)
0Two DSS Consoles (P/N 15151 or P/N 15351):
The B-HBU-A PCB (P/N  is a daughter board for: the B-TSU-A Tone Sender PCB that provides:
0Connections for two alarm sensors
0Connections for customer-supplied MOH and BGM
0External alarm signals to stations

lines
SMDR
INTERFACE PCB
The B-SMDR-LA PCB,required for SMDR on a BUSINESSCOM
PLUS 
 contains:
0Circuitry for controlling printing options and
formatting transmission data
0A buffer for storing station message data for a
maximum of eight calls per CO line when the
printer is busy.
SMDR on a BUSINESSCOM PLUS  requires the following
equipment:
0Installation of the B-SMDR-LA PCB
0B-SMDR-LA Cable Kit (P/N 15346 or 15347)
0Installation of a B-MPU-B or a B-MPU-C PCB
