STS 3192–9M ASPR Office Repeater
■Document Purpose
▲This document provides general information for the Charles Industries 3192–9M Automatic Span Regulator (ASPR) Office Repeater.
■Equipment Function
▲The 3192–9M provides T1 span regeneration and powering in STS mountings. The fully temperature hardened (–40 to 149F [–40 to 65C] ambient temperature range) 3192–9M can be located in central offices, and outdoor or customer premises cabinets and CEVs.
■Equipment Features
▲This unit provides the following features.
◆An automatic span regulator (ASPR) to derive the necessary span line voltage (10 to 130Vdc) to maintain a 60mA loop from –48Vdc office battery. The ASPR automatically compensates for variations in cable, repeater tolerances, temperature and routing.
◆A wide range automatic line build-out (ALBO) that will regenerate incoming signals that have experienced from 0 to 35dB of loss. No optionable padding of the incoming signal is required.
◆A fixed 4.5dB transmit side LBO pad.
◆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.
◆Aupports spans operating at 60mA. Provision is made for bidirectional span powering only. The design of the T1 span, including repeater spacing and cable pair selection, should be done according to standard T1 span design or local company practice. Bell Operating Companies can use the DILEP II System described in Bellcore Practice BR-902-200-120.
◆Delivers up to –130 volts to the span into a maximum DC simplex span resistance of 2100 ohms. Consideration should be given to back-powering spans that exceed the 2100 ohm limit, or use a 3192–9L which delivers up to 260 volts to the span.
◆When the 3192–9M'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. The fuse is not field replaceable.
◆Front-panel-mounted pin jacks for measuring span current and voltage.
◆Fixed DSX pre-equalization for up to 110 feet of 22 gauge cable
