*Actual distance dependent upon physical characteristics of network installation.
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.
T1:
Gauge 24 to 22 AWG
Attenuation 2.6 dB/100 meters @ 1.0 MHz
Differential Characteristic Impedance 100 ±10%
E1:
Gauge 24 to 22 AWG
Attenuation 2.6 dB/100 meters @ 1.0 MHz
Differential Characteristic Impedance 120 ±10%
Coax Copper Cable
E1:
Gauge 24 to 22 AWG
Attenuation 2 dB/100 meters @ 1.0 MHz
Differential Characteristic Impedance 75 ±10%

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.
