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 twisted­pair (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 Ω±10%

E1:

Gauge 24 to 22 AWG

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.

Refer to drawings below and at right
for four-position switch settings.

5. Is the AISTP LED on either media converter illuminated?
YES

• Determine and correct failure of remote unit connected to twisted-

pair interface that caused All Ones Insertion (AIS) on the twisted-

FAULT ISOLATION and CORRECTION

If the media converter fails, isolate and correct the failure by determining the
answers to the following questions and then taking the indicated action:

1. Is the Power LED on the media converter illuminated?
NO

• Is the power adapter the proper voltage and cycle frequency for the

AC outlet?
NOTE: Refer to the “Power Supply Requirements” on page 7.

• Is the power adapter properly installed in the media converter and

in the outlet?

• Contact Technical Support: [phone]/(800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the SDFiber (Signal Detect/Fiber) LED illuminated?
NO

• Check fiber cables for proper connection.

• Verify that TX and RX cables on media converter are connected to

RX and TX ports, respectively, on other media converter.

• Contact Technical Support: [phone]/(800) LAN-WANS.

YES

• Proceed to step 3.

3. Is the SDTP (Signal Detect/Twisted-Pair) LED illuminated?
NO

• Check twisted pair cables for proper connection.

• Check RJ-45 Pinning Switch for correct twisted pair cable

configuration.

• Check integrity of device attached to media converter by twisted-

pair cable.

• Contact Technical Support: [phone]/(800) LAN-WANS.

YES

• Proceed to step 4.

4. Is the AISFiber LED on either media converter illuminated?
NO

• Proceed to step 5.

YES

• Determine if broken fiber link has caused All Ones Insertion (AIS)

on the fiber interface and correct failure. If not, proceed to step 5.

Set switches 5, 6, and 7 to
enable test functions or to
permit normal network
operation. (Switch 8 not used.)

Set the MDI/MDI-X switch to use straight-through cable where crossover­configuration cable is required.
