Description and application
The Fiber Link T-1 Model 2 (backwards compatible with the Model 1) System processes incoming bipolar signals
(7.2 V P-P Max) within a bandwidth of 100 KHz to 10 MHz T-1 (1.544MbpS) or (CCITT 2.048MbpS), optically
transmits these signals over fiber optic cable and converts the signal to the original electrical signal with minimal
gain or loss.
Output to the copper line is automatically maintained at a nominal level. The Fiber Link system is compatible with
European E1. Transient voltages appearing on or between the 4-wire pairs and/or power supply input are limited by
thermistors, gas tubes and MOVs.

Before installing
1. Observe special handling requirements
1.1
Be careful when handling electronic components
ATTENTION
ELECTROSTATIC
SENSITIVE
DEVICES
•
This product contains static sensitive components.
•
Handle the T1 cards at their edges only.
•
Follow proper electrostatic discharge procedures.
This card utilizes circuitry that can be damaged by static electricity. When transporting the card, carry it in an ESD safe
container such as the antistatic bag provided with the card. Before handling cards, discharge yourself of static electricity by
physical bodily contact with earth ground. When handling cards, hold by outer edges and avoid touching circuitry. Failure to
follow ESD precautions may cause serious damage to the card and prevent proper operation.

Guidelines for handling terminated fiber cable
•
Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber.
•
Keep dust caps on fiber optic connectors at all times when disconnected.
•
Do not remove dust caps from unused fiber.
•
Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause signal
loss.
•
Do not touch fiber ends.
•
Store excess fiber on housing spools or fiber spools at site
•
Do not staple fiber cable to back boards or over tighten cable ties. Excess pressure on fiber can cause damage.

different parts of the system during installation.
Isolating the source of trouble is essential to determining the steps needed to fix the problem. Most installation
problems can be easily fixed in the field once the problem is properly identified.
Common Issues
Most problems encountered during installation and testing can be attributed to these 4 issues:
•
Problems with the CO side or incoming T-1 signal
•
Problems with the Sub side or T-1 signal output
•
Problems providing correct power to the cards
•
Problems with the copper connections wiring due to nicking, scoring or poor terminating
•
Problems with the fiber optic cable
RLH T-1 cards are built to the highest standards and fully tested before leaving the factory.
Isolating and ruling out common issues with the installation will help determine if there is a problem with the card
itself.
Troubleshooting 31
CO side troubleshooting
Cannot set gain.
The incoming T-1 input peak-to-peak voltage is out of range.
If the P-P voltage is out of range you may not be able to set the gain correctly for the CO card to function normally.
This can result in an output level on the Sub side card that is either too weak or too hot. If the Incoming T-1 P-P
voltage is too high on the incoming side, it may need to be attenuated before setting the CO card gain.
•
Refer to the Installation Section 2 for setting the CO card gain.
Each jumper position on the CO card is equivalent to approximately 6dB gain. Setting the gain correctly ensures
the correct signal strength for transmission over fiber and a matching output signal on the Sub side output.
Fiber loopback doesn’t turn on green RCV LED.
A signal isn’t being received at the fiber connection.
•
Check the incoming power to the card with the BLU LED.
•
Verify that the GRN XMIT LED is ON, indicating that a T-1 signal is present.
•
Check that the fiber jumper isn’t damaged or contaminated.
Sub Side troubleshooting
The green XMIT LED remains OFF with copper loop-back jumper
Indicates that no T-1 signal is being transmitted back to the CO card
•
Check the correct connection of the fiber cable. The fiber connections must be flipped for correct operation.
•
Verify that the fiber cable is good. Check that the GRN RCV LED is ON, indicating a fiber signal is being received
from the CO card. See the section on testing the fiber.
•
If using multimode system over 4,000 ft., verify that the CO and Sub multimode switches (SW1) are ON.
The output P-P V is out of range
•
Check for correct T-1 signal input at CO card.
•
Check the GAIN jumper setting on the CO card.
The Sub card reproduces the signal transmitted by the CO card. If the Sub card output is too high or too low, the
loss select jumper position may not match the CO side, or the CO gain may be set incorrectly. Refer to the
Installation Section 2 for setting the CO card gain.
•
Make sure the LOSS SELECT jumper on the Sub card matches the CO card.
Refer to Installation Section 6.3 Set loss select jumper for setting the Sub card gain.
Refer to the Specifications section for output signal (Sub side card).
32
Troubleshooting
Power supply issues
Blue PWR LED remains off
The T-1 card isn’t receiving proper power.
•
Check power by using a multimeter on the top of the screw-down terminals.
If using Span power
•
Check across the INPUT and OUTPUT terminals. Power must be 22VDC minimum.
•
Check the NIU compatibly chart for NIU systems providing span power.
•
If Span power is too low or not provided, repair the T-1 line or use an auxiliary power source.
•
Check wiring for nicking, scoring or poor termination.
Use 22~24AWG solid wire for power supply connections.
Refer to the power supply connection and use information for fuse or circuit breaker requirements. Use caution
when handling copper wiring. Power connections may carry high voltages.
Fuses must be installed within a finger safe housing to prevent electric shock from accidental contact or during
fuse replacement.
If using auxiliary power
•
Check the AUX P.S. terminals for 24-56VDC, 55-75mA.
•
No AC power can be detectable on the DC power line.
•
Check wiring for nicking, scoring or poor termination.
Troubleshooting 33
Verifying fiber cable
When T-1 signal is present
Verify the fiber cable when the CO card fiber loopback test is good, but the Sub side GRN RCV LED will not go on,
indicating that a fiber signal is not being received. Refer to Installing into working environment step 5.5, or
Installing prior to T-1 service step 5.4 for information on the CO fiber loopback test.
Use the accessory test kit coupler to verify fiber cable continuity. The CO card must be powered and connected to
a T-1 signal.

Troubleshooting
When T-1 signal is not present
The T-1 cards have a fiber signal test system built-in. You can verify the fiber cable when there is no T-1 signal
present. Both the the CO and Sub cards need to be powered (a battery may be used) and the fiber cables need to
be connected correctly to the cards. Refer to the installation sections for power and fiber connection information.
You may use either the CO or Sub card to send the test signal. On the send side, set the SW2 FIBER SIGNAL
switch to ON. At the receive side, the yellow FIBR LED will go ON, indicating that the fiber cable is OK. You may
repeat this test from the opposite side.
Set the SW2 FIBER SIGNAL switch to OFF once the test is completed.
If the receive side LED does not turn on, test the fiber cable using a fiber optic test set with light source and meter.
See the T-1 System Fiber Test Specifications chart on the previous page for test specifications.
Troubleshooting 35
Connecting T-1 service after installation
When connecting T-1 Service AFTER the Fiber Link has been pre-installed, make sure to check the following.
•
Verify span or auxiliary power to the CO card at the card terminals (page 15)
•
Set the gain using the GAIN jumper on the CO card (page 16)
•
Set the LOSS SELECT jumper on the Sub card to the same setting as the GAIN jumper on the CO card (page 19)
•
Verify auxiliary power to the Sub card at the card terminals (page 20)
