Pin Assignments

NOTE:

"SN" in "Cable and SN" is the print on the cable sheath.

A 75-ohm E1 trunk cable consists of the shield layer and wire.

In the following table, "Rx/Tx Channel" indicates that the transmitting is from the board and the receiving is to the board.

  • R0: receive end of channel 0 E1 signals
  • T0: transmit end of channel 0 E1 signals
