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.
