Cabling
To meet Part 15 of EMC Rules, ISDN PRI equipment must be connected using CAT5,
Shielded Twisted-Pair (STP) cabling between the NTE and the RPTU. CAT5 STP protects
against cross talk, Radio Frequency Interference (RFI), and/or Electro Magnetic Interference
(EMI). STP protects ISDN signal data while being transmitted through the cable and keeps
the cable itself from emitting EMI and RFI.
Important!
To avoid ground loops, connect only the RPTU end of the shielded cable to
earth. The NTE earth should not be connected to the cable shield.
A detailed pinout diagram for the RJ45 jacks and the modular cords/adaptors is shown in
Toshiba will ship a 5 metre shielded patch cord terminated with BS EN28877 connectors with
each RPTUIF.
Cable Installation
The RPTU PCB is shipped with a Toshiba RPRI cable kit for connection of the RPTU to a
CSU. Install the kit as shown in
