1.3 System-Level Application
The simplex repeater regenerates DS3, E3, and STS-1 signals to equal level point over a
distance of up to 900 ft (using RG-59/734 cable). Two repeaters are required to regenerate
both the send and receive signals and complete the cross-connect.
The repeater regenerates the signal that appears on the IX port and transmits it out the I port for
a length dependent upon the type of cable used. See Section “2.1 Installation” on page 6 to set
the module jumpers based on cable length.
The OX and O ports are passive; therefore, a second repeater is required to regenerate and
transmit the signal in the other direction. Each network element can be located up to 900 ft from
the far-end repeater’s IX port.

2.1.1 Installation Considerations
CAUTION
!
CAUTION! Only qualified technicians may install and maintain this product.
ALERT
!
ALERT! These instructions presume you have verified that the Telect equipment being in-
stalled is compatible with the rest of the system, including power, ground, circuit protec-
tion, signal characteristics, equipment from other vendors, and local codes or ordinances.
ALERT
!
ALERT! This repeater module contains static-sensitive components. To prevent equip-
ment damage, wear a properly connected grounding strap while handling the module and
store it in its original anti-static bag when not in use.
2.1.1.1 Location and Space
The BCS II Simplex Repeater module occupies one slot in any vertical BCS II chassis or in the
Vector chassis. Do not install more than five repeater modules in a BCS II chassis. The Vector
Chassis can be fully populated with repeaters. You must install two repeaters to complete the
cross-connect, one repeater for each network element.
2.1.1.2 Tools and Equipment
No special tools or equipment are required. Wear a grounding strap during installation.

2.1.1.3 Power
–42 Vdc to –58 Vdc power reaches the module through the backplane connector on the chassis.
Power to the backplane connector block is delivered from the power distribution panel using 16–
22 AWG wire. See the chassis user manual for additional information on power transmission.
Because the repeater is an active product, Telect recommends using a dual-feed power source.

2.1.1.5 Inspection
Compare the contents of the shipping container with the packing list. Call Telect if you are
missing anything.
NOTES:
Telect is not liable for shipping damage.
If the shipping container is damaged, keep it for the carrier’s inspection. Notify the carrier and
call Telect’s Customer Service Department: 1-800-551-4567 or 1-509-926-6000.
Keep the container until you have checked equipment operation. If you experience any kind
of problem, call Telect’s Customer Service Department. Use the original, undamaged con-
tainer if you are instructed to return the product to Telect.
2.2 Installing the Repeater
Procedure steps:
1. Identify the two network elements you wish to cross-connect.
2. Plan placement of the two repeater modules in relay racks, ensuring that
−The distance between the network element and the repeater is correct for the system, ca-
bles in use and office procedures. This can be up to 450 feet.
−The two repeater modules will not be more than 900 feet apart.
3. While wearing a grounding strap, remove the repeaters from their anti-static bags, touching
the module edges only.
4. Set the jumpers on each module for the appropriate data rate, as shown below. (Factory set-
ting is T3.)

5. Set the jumpers for the transmit and receive distances, as shown below. (Factory settings are
Low and Short.) See the tables following to determine the settings appropriate for the type of
cable being used.

CAUTION
!
CAUTION! Only qualified technicians may install and maintain this product.
4.1.1 Owner Maintenance
Telect’s BCS II Simplex Repeater module does not need preventive maintenance. The only part
you can replace is the tracer lamp LED.
4.1.1.1 Replacing the Tracer Lamp LED
Procedure steps:
1. Pull the defective LED straight out with your fingers.
2. Align the replacement LED with the LED socket in the faceplate. Notice that the socket is
keyed, and the LED enters only one way.
ALERT
ALERT! Do not bend the LED’s two metal leads.
3. Gently insert the LED into the socket, as shown on the next page. If you encounter resis-
tance, do not force the LED into position. Move it until it slides easily into the jack module.

4.1.5 Repacking For Shipment
1. Tag the equipment with owner’s name, address, and telephone number, together with a
detailed description of the problem.
2. Use the original shipping container if possible. If you do not have it, package the equipment in
a way to prevent shipping damage. Include the RMA inside the container and legibly print the
RMA number on the outside of the package, near the shipping address.
3. Insure the package.
NOTE: Telect is not liable for shipping damage.
