1. If this switch on the Primary Clock source RPTU is pressed (Program *42-1), the clock source will automatically
revert to the Secondary Clock source PCB (Program *42-2).
Resets or initializes the RPTU firmware. Press this switch
to correct an out-of-service condition, or just prior to
connecting to the Network PRI.
JP1 & JP2 (Loop-back jumpers)
Makes loop-back tests of the cabling between the ISDN
Network switch, CSU, and RPTU.
J1 8-pin Modular Connector (RJ45)
Connects the RPTU to the CSU/network PRI ISDN line.
J2 6-pin Modular Connector (RJ11)
Connects the RPTU to a terminal or PC to monitor
