The TWOx12 has 2 Desktop Director™ ports in Interface slot F. Power is provided on pins 7 & 8 for
one Director per port. If more than one Desktop Director™ is required on a single port an external
power supply will be required (see below).
This interface is a standard modular RJ-45 style jack and is has the data pairs
exchanged as compared to an ISDN S interface or the Desktop Director. Therefore a
“straight through” (non-crossover) cable is used between the TWOx12 and the Desktop
Director as follows.
