PRI Connection (RJ-48)
Caution: Always use standard telecommunication cables with a minimum of 26 AWG wire gauge.
PRI connections use two pairs of wires: one pair for transmission and the second pair for reception. It is wired so that pins 1 and 2 are on one twisted pair
and pins 4 and 5 are on a second pair according to common wiring standards which meet the TIA/EIA 568A and 568B requirements.
Note: The Mediatrix unit PRI ports can be used as a T reference point, but not as U reference points (2-wire). Never connect a U PSTN line or a U TE into
the Mediatrix unit PRI ports.

BRI S/T Connection (RJ-48)
Caution: Always use standard telecommunication cables with a minimum of 26 AWG wire gauge.
BRI S/T connections use two pairs of wires: one pair for transmission and the second pair for reception. It is wired so that pins 3 and 6 are on one twisted
pair and pins 4 and 5 are on a second pair according to common wiring standards which meet the TIA/EIA 568A and 568B requirements.
Caution: The Mediatrix unit ISDN BRI ports are configurable to operate as network or terminal ports. The pin-out of the sockets is switched according to
this configuration. Wrong port configurations, wrong cabling or wrong connections to neighbouring equipment can lead to short circuits in the BRI line
powering.
