STS 3192–9P Short Loop Office Repeater
■Document Purpose
▲This document provides general and testing information for the Charles Industries 3192–9P Short Loop Office Repeater
■Equipment Function
▲The 3192–9P is an optionless repeater intended for applications where T1 service is provided to a customer premise via a lightwave multiplexer and short non-repeated metallic extensions are provided beyond the normal DSX range. In this application, a STS shelf equipped with 3192–9P units is co-located with the fiber multiplexer providing up to 3000 foot repeaterless metallic extensions. The 3192–9P contains a –48 volt current regulator that provides simplex current at a constant 60mA to power a DS1 Connector located at the Network Interface. The 3192–9P cannot be used in T1 service applications where the Local Exchange Carrier provides network power to operate the customer's T1 CSU.
■Equipment Features
▲ Provides a wide range ALBO (Automatic Line Build-Out) that will regenerate incoming signals that have experienced from 0 to 35dB of loss. No optionable padding of the incoming signal is required.
▲Transformer-coupled passive transmit path with a fixed insertion loss of approximately 1.0dB.
▲Provides a fault locate output. A resistive network on the secondary of the fault locate transformer provides the proper termination to the repeater when fault locate filters are not being deployed; eliminating the need to short the fault locate output when not in use.
▲When the 3192–9P's internally-located fuse opens, the front-panel-mounted FA LED will illuminate and –48 volts will appear at the Fuse Alarm output (pin 10). The fuse will only open if the module is damaged and the fuse is not field replaceable.
▲Front-panel-mounted bantam jacks that provide split and monitor access to the DSX.
▲Front-panel-mounted pin jacks for measuring span current and voltage.
▲Provides a fixed pre-equalization for up to 110 feet of 22 gauge cable or 90 feet of 24 gauge cable.
