Note
The Strata DK40 system assigns one station port number to each Tie Line connected. These
station port numbers are only available in order to program certain attributes to the Tie Lines
connected to the PEMU, PACU PCBs, (i.e. Toll Restriction and Least Cost Routing). For a
list of the station port numbers assigned to each PEMU PCB/Tie line circuit

PEMU Installation

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.
