Note 1: For the SILC port designations shown in this table, substitute Tx- Tx+ Rx+ Rx- for every
occurrence of T- T+ R+ R-.
Note 2: The cable pair designated Tx- Tx+ is the transmit pair. The pair designated Rx+ Rx- is the
receive pair. An SILC port supplies 2 watts of power at -48 V (-40 V for international), simplexed over the
transmit and receive pairs, where the transmit pair is negative with respect to the receive pair.
