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 Installation

2.1.1 Installation Considerations

CAUTION! Only qualified technicians may install and maintain this product.

ALERT! These instructions presume you have verified that the Telect equipment being installed is compatible with the rest of the system, including power, ground, circuit protection, signal characteristics, equipment from other vendors, and local codes or ordinances.

ALERT! This repeater module contains static-sensitive components. To prevent equipment 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.

Page 6

Page 10

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 container 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 setting is T3.)

Page 11

5. Set the jumpers for the transmit and receive distances, as shown below. (Factory settings are

4.1 Service

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! 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 resistance, do not force the LED into position. Move it until it slides easily into the jack module.

4. When the LED snaps into place, the installation is complete.

5. To test the new LED, insert a plug into the “M” (monitor) jack. The LED flashes for about 30 seconds, then lights steadily.

This procedure is complete.

4.1.2 In Case Of Difficulty

If problems occur after initial installation, check all cable connections and the installation instructions in Chapter 2.

4.1.3 In-Warranty Service

Contact your Telect equipment distributor, or call a Telect Customer Service Representative: 1-800-551-4567

1-509-926-6000 Telect will repair or replace defective products within the limits of the warranty. See “Repacking

for Shipment” in this section. NOTE: Call a Customer Service Represent ative for a Return Material Authorization (RMA) before

returning any equipment.

4.1.4 Out-Of-Warranty Service

The procedure for out-of-warranty service is the same as for in-warranty service, except that Telect charges a processing fee, and you must submit a Purchase Order along with a Return

Page 13

Page 17

Material Authorization (RMA) before returning equipment. Call a Customer Service Representative for help getting these forms.

The processing fee guarantees a repair estimate and is credited against actual material and labor costs.

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, p ackage 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.
