4.5.6 RING GENERATOR INSTALLATION
The Ring Generator Unit is needed in the
Aria
-34e KSU when any Single Line Telephone
Devices are supported. This includes a modem, fax or an industry standard AUSTEL approved
SLT. These devices interface with the 4SLI or SLIB cards in the system. The RGU is used to
provide ringing and message wait source power for the SLT devices.
The RGU is mounted on the bottom right side of the KSU with two (2) screws and is connected
to the Main Board Unit (MBU) on CN5 connector. A ferrite core (supplied) must be fitted to the
connecting cable from the RGU to the MBU for EMI suppression.
