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.

Dry-Contact Relay

RJ-45 dry-contact relay opens if power, signal detect/copper or signal
detect/fiber are lost.

Operational rating on pins 3 and 6: 0-30VDC maximum 1A

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.
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.
