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

TP Fiber TP

A loopback switch facilitates installation and network debug procedures. The path for the T1E1-CF-01 loopback is shown:

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 interface when signal detect is lost, which creates an alarm condition at the equipment connected to the interface.
