Configuration.).
Note
For the system to recognise the DTMF tones generated by incoming Tie lines a
DTMF Receiver Unit (BRCS) must be installed on the Strata CTProcessor PCB(s).
The Strata CT system assigns one station port and one trunk port number to each Tie Line
connected.
PEMU controls, indicators, and interface connectors are shown in
in
Table

1.
Determine if the E & M tie lines will be configured for 2- or 4-wire transmission.
2.
Set the 2W/4W jumper plugs P103, P203, P303, and P403 to the appropriate positions.
3.
Set the FG jumper plug P3 to the "2-3" position.
4.
Set all GND/BAT jumper plugs to the "BAT" position for connection to the telephone
network.
5.
Insert the PEMU (component side facing right) into the appropriate Expansion KSU
cabinet slot and apply firm, even pressure to ensure proper mating of connectors.
Important!
Each PEMU decreases the maximum system exchange lines by four each.
6.
After installing, gently pull the PEMU outward. If the connectors are properly mated, a
slight resistance is felt.
