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.
Note
5. Insert the PEMU (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors.(For DK40i, the REMU, PEMU can be
installed only in place of the RDDU per tables in
Important!
6. After installing, gently pull the PEMU outward. If the connectors are properly mated, a slight
resistance is felt.

PEMU, REMU Programming

Program 03: Specify Code 13 for slots that support PEMUs and make sure RRCS is enabled for
DTMF operation.
Program 04: Specifies [PDNs]. These are also the numbers that must be received by incoming Tie
lines to route calls to the proper telephones (see Program 17, LED 05).
Program 10-1: Enables/disables two-line conference.
Program 15: Assigns tandem connections and dial pulse option to Tie lines.
Program 17: Assigns immediate or wink start to REMU Tie lines.
Important!
Note
Program 30: Disables RRCS for dial pulse operation.
Program 71 (1~5) and Program 72: Tie/DID DNIS assignments.
Program *71~*73: DH/Tie/DID to [DN] ringing assignments.
Program 93: Assigns a name to a Tie line
9-44
The "GND" position is used to connect PEMU circuits back-to-back on premises only,
1000 feet maximum (E&M lead wires must be crossed).
Each PEMU decreases the maximum system CO lines by four. Tie lines do not use
station ports in DK40i, DK424 and DK424i in Release 4.0 and higher. See
Worksheets in the appropriate configuration chapter for recommended PEMU slot
assignments.
Also used to turn on Tie line dial tone return.
When a PEMU or REMU is installed in a system, it automatically assumes the next four
consecutive CO line and station port numbers.
