Section 319–29E–202 1. GENERAL 1.1 Document Purpose This document provides general, circuit, and testing information for the Charles Industries Span Termination System (STS) 3192–9E Powering T1 Network Interface Unit (NIU), shown in Figure 1. The 3192–9E is a member of the Charles Industries STS–3192 family of high density span termination equipment. For additional information on the STS–3192 System, see sections 319–211–100 and 319–211–200. 1.

Section 319-29E-202 2. APPLICATION ENGINEERING The 3192–9E is ideally suited for use in provisioning T1 High Capacity Digital Service (HCDS) from lightwave-fed building Remote Terminals located at customer premise locations. See Figure 2 for a typical application. The 3192–9E, used as adjunct equipment to the Lightwave Multiplexer, provides transmission loopback for maintenance activities.

Section 319–29E–202 The 3192–9E input current is highly dependent on application. Those applications that require the 3192–9E to power a customer’s CSU will require a greater input current. Table 1 shows input current and heat release versus the equivalent series simplex resistance (at 60mA) present on the CI side of the unit. Table 1. 3192–9E Power Consumption and Heat Release Typical Application Option S1 Position Equivalent External Simplex Resistance –42.5 Volt Battery I W 48.0 Volt Bat- 56.

Section 319-29E-202 3.1 Signal Transmission Paths In the idle (Looped down) mode, the signal from the network is coupled to the unit and routed through the transmit pad circuit. Switch S4 mounted on the circuit pack is used to adjust the transmit pad which consists of two cascaded 7.5dB sections, allowing transmit path losses of 0, 7.5 and 15dB. The signal from the customer is routed through the receive side of the 3192–9E.

Section 319–29E–202 3.5 Transmit And Receive Signal Detectors The 3192–9E provides Monitoring Signal Detectors on the transmission paths. These detectors provide a maintenance aid for installation and troubleshooting. 3.6 Network Side Signal Detector This detector monitors the unit’s transmit path and looks for signal activity from the network. When a LOS (Loss Of Signal) is detected, as indicated by receipt of 175 +75 consecutive zeros, it will illuminate the front panel NET LOS LED.

Section 319-29E-202 4. INSPECTION Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately report the extent of damage to the transportation company. Wescom equipment is identified by a model and issue number imprinted on the front panel or located elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue number is advanced by one number on any subsequent models that are manufactured.
