Twisted-Pair Copper Cable
Twisted pair connection requires two active pairs. The two active pairs in a T1/E1
network are pins 1 & 2 and pins 4 & 5. Use only dedicated wire pairs (such as
blue/white & white/blue) for the active pins.
Category 3 or better twisted-pair copper wire is required. Either shielded twisted-
pair (STP) or unshielded twisted-pair (UTP) can be used.

Switch-Selectable Configurations
T1 COPPER RJ-45
Configured as either "long haul" or "short haul" on 100 ohm cable, with
a variety of selectable distance settings.
E1 COPPER RJ-45
Configured as either "long haul" or "short haul" on 120 ohm cable.
E1 COPPER COAX
Configured as either "long haul" or "short haul" on 75 ohm cable.
STRAIGHT-THROUGH/CROSSOVER RJ-45
Allows straight-through cable to be used where crossover-configuration
cable is required.
Switch-Selectable Functions
LOOPBACK TEST FUNCTION
A loopback switch facilitates installation and network debug procedures.

TRANSMIT ALL ONES FUNCTION
A selectable Transmit All Ones switch on the fiber interface and on the
twisted-pair interface allows for insertion of an "all ones" pattern on that
