Pin 8: (Port 2) R - Receive from network

Pin 7: (Port 2) T - Receive from network

Pin 6: (Port 2) R1 - Transmit to network

Pin 5: (Port 1) T1 - Transmit to network

Pin 4: (Port 1) R1 - Transmit to network

Pin 3: (Port 2) T1 - Transmit to network

Pin 8

To access Trunk 1, Trunk 2, or both Trunks 1 and 2, connect a shielded T1 or E1 RJ-

45 cable to one or both 8-pin modular jacks on the board.

To access all four trunks, use two dual T1/E1 120 ohm trunk adapter cables. Each

trunk adapter cable separates the 8-pin modular jack on the board into two RJ-48C

interfaces.
