RLXIOR INSTALLATION AND TESTING

Summary:

This procedure provides instructions for installing the Repeater Loop Extender

Intelligent Office Repeater (RLXIOR) module in the chassis. A typical deployment consists of
an RLXIOR module installed in a chassis that is connected to a repeater or a series of line
repeaters. There is no protection for this signal, and an MPU must be installed to enable
configuration and alarm reporting for this module.

The installation procedure consists of unpacking the RLXIOR, setting two configuration
switches, installing the RLXIOR in the chassis, and verifying that it is functioning
properly. The RLXIOR may be installed in either a Soneplex Broadband chassis or a
Soneplex Loop Extender chassis.

Caution:

To enable span power on the RLXIOR module, a proper connection must be

made between chassis ground and –48V return at a location in the central office,
following local practices. It is recommended that this connection be made outside the
Soneplex chassis.

Caution:

Electronic modules can be damaged by electrostatic discharge (ESD). Before

handling modules, wear an anti-static discharge wrist strap to prevent damage to
electronic components. Place modules in anti-static packing material when transporting
or storing. When working on modules, always place them on an approved anti-static mat
that is electrically grounded.

1. Open the shipping carton and carefully unpack the RLXIOR from the protective packing

material. See

Figure 524-1

2. Set the configuration switches on the RLXIOR to match the requirement of the work order.

See

Figure 524-2

for the location of switches. The following operating parameters are

switch-selectable:

•

Line Power (–130 Vdc or ± 130 Vdc)

•

Channel Blocking Idle Code (7Fhex or FFhex)
