PCB Chapter Layout
Each PCB outline begins with the PCB’s designation and title (the outline appears in the
chapter in alphabetical order by designation). A brief synopsis of the PCB appears next and
includes a notation of the system(s) that the PCB can be used in, the circuits supplied by the
PCB, what equipment the PCB interfaces with, and a list of the PCB’s older version(s) with a
brief description of their differences.
Installation and programming instructions follow the synopsis with a table showing the
PCB’s controls, indicators and connectors and an illustration of the board.

PCB Title
System:
Circuits per PCB:
Gives the type of system that is
compatible with the given PCB. Be
sure to read this information before
attempting to use a PCB with your
system application.
Type and number of circuits
available on the PCB.
Type of line/hardware the PCB can
accept.
Interfaces with:
Describes older version or versions
of the PCB.
Older Version(s):
Only one telephone (or device) can be connected to a RSTU2 port. If more than one telephone
or device is connected to a port or ringing may not function.
Notes
●
For the system to recognise the DTMF tones generated by a standard telephone (or
any other device connected to a standard telephone port), a DTMF receiver Unit
(K5RCU) must be installed on the Strata CT.
●
Most standard telephones and two-wire devices require the 190VP-P level; however,
some devices may experience ring-trip with 190VP-P and should be set for 130 P-P.
See Figure 3-4 for an illustration of the PSTU2. Figure 3-5 shows the RSTU2. See Table 5-4,
for details of the PSTU and RSTU2 controls and indicators.
Which system slot(s) the PCB can
be installed into.
