The duplexer (see Figure 1) acts as an isolation filter and separates the transmitted (Tx) signals from the received (Rx) signals.
The duplexer assembly is an integral part of the wireless transverter and has an N-type, female, weatherized connector for attaching the antenna cable (see Figure 2).
The duplexer is shipped as a separate unit. The duplexer you receive is based on the RF channel plan you have selected for your installation.
This section provides a list of parts and tools that you need to remove and replace the duplexer in the wireless transverter. This section also includes safety and ESD-prevention guidelines to help you avoid injury to yourself or damage to the equipment.
To remove and replace the duplexer assembly, you need the following tools and parts. If you need additional equipment, contact a service representative for ordering information.
|
Note Some N-type connectors require specific tools. Obtain this information from your cable vendor. |
|
Note If the optional hail shields have been installed, remove them first. Refer to the instructions that shipped with the shields. |
The following are safety guidelines that you should observe when working with any equipment that connects to electrical power or telephone wiring.

Follow these basic guidelines when working with any electrical equipment.
Use the following procedures to remove and replace the duplexer in a wireless transverter.
|
Note You can remove and replace the duplexer without removing the transverter from the antenna mast. |
 |
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. This equipment contains an energy hazard. Disconnect the system before servicing. To see translations of the warnings that appear in this publication, refer to the "Translated Safety Warnings" section of this document. |
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. To see translations of the warnings that appear in this publication, refer to the "Translated Safety Warnings" section of this document. |
To remove an installed duplexer from a wireless transverter, complete the following procedures:
1. Shutting Down the Wireless Link
4. Removing the Duplexer from the Transverter
|
Note If the duplexer will be replaced in the wireless transverter before the transverter is installed on the antenna mast and power is applied to the system, proceed to the "Removing the Duplexer from the Transverter" section. |
The duplexer should be removed only when the transverter is not transmitting a signal. Use the procedures established at your installation and the shut command to shut down the appropriate sector in the wireless link.
To disconnect the DC power from the individual transverter, complete the following steps:
Step 2 Tape the power/breaker switch for the transverter in the OFF position.
|
Warning Before performing any of the following procedures, ensure that DC power to the transverter you will be working on is turned OFF. To ensure that the power to the specific transverter is OFF, locate the power/breaker switch on the front of power feed panel that services that transverter, push the switch into the OFF position, then tape the switch in the OFF position. To see translations of the warnings that appear in this publication, refer to the "Translated Safety Warnings" section of this document. |
Remove the antenna cable from the N-type connector on the duplexer (see Figure 4).
To remove the duplexer from the transverter, complete the following steps:
Step 2 Remove the duplexer assembly (see Figure 6), and set it aside, being careful not to damage the internal RF connectors.
To replace the duplexer, complete the following procedures:
Make sure that you install the replacement duplexer in the correct orientation. When it is installed in the transverter, the orientation of the duplexer determines its transmit and receive frequencies for that transverter sector.
|
Note The choice of Tx Hi or Rx Hi must match the frequencies configured for the multipoint wireless modem card using the command-line interface or CiscoView. |
To install the duplexer in the transverter, complete the following steps:
Step 2 Detach the bottom portion of the label affixed to the underside of the duplexer (see Figure 7) and record the duplexer orientation. This label can be attached to equipment records and used for reference when configuring the system or performing maintenance.
Step 3 Depending on whether that sector is transmitting or receiving on the high-frequency band, match the notched end of the duplexer with either the Tx Hi or Rx Hi side of the duplexer receptacle in the transverter (see Figure 8).
Step 4 Verify that the gasket is aligned in the groove in the transverter chassis (see Figure 9).
Step 5 Carefully line up the duplexer and plug it into the chassis, being careful that the internal RF connectors are properly aligned.
Step 6 Verify that the cover of the duplexer housing is flush with the transverter housing.
 |
Caution If the cover is not flush, check the alignment of the internal RF connectors. In order to avoid damage, never tighten the captive screws until the cover is flush. |
Step 7 Using the torque driver with the number 2 Phillips bit, follow the numeric sequence in Figure 10, and lightly seat the screws.
Step 8 Repeat the sequence in Figure 10, tightening the screws to between 16 and 20 inch-pounds of torque.
|
Note If you removed the transverter from the mast before replacing the duplexer, the remaining steps do not apply. To install the multipoint wireless transverter on an antenna mast, refer to the instructions shipped with the transverter or to the Cisco uBR7200 Series Multipoint Wireless Modem Card and Subsystem Installation document that shipped with your multipoint wireless modem card. |
Connect the antenna cable to the N-type connector on the duplexer (see Figure 11).
|
Note After connecting, apply cable-connector weatherproofing to the antenna cable connection. |
To reinstate the power, complete the following steps:
Step 2 Reinstate power by moving the power/breaker switch to the ON position (see Figure 12).
To reinstate the wireless link, complete the following steps:
|
Note Entering the insertion loss parameter is optional. If this parameter is omitted, the value 1dB will be assumed. |
Step 2 Using the procedures established at your installation, reinstate the wireless link with the no shut command.
This completes the procedure for removing and replacing the duplexer in a Cisco broadband fixed wireless multipoint system headend wireless transverter.
