  • Page 9: Pg-Flex System Overview

    PG-Flex is a small-capacity, universal subscriber carrier system supporting up to 24 channels on two pair of existing copper wires. A PG-Flex system is comprised of one line unit and one (or more) channel units at both the Central Office and the Remote Terminals (Figure 1). The Central Office Terminal (COT) line unit takes the CO battery and converts it to the voltages necessary to operate the COT line units and channel units, and supplies power to the RT equipment.

  • Page 11: Central Office Terminal Equipment

    Channel Unit(s) COT Shelves COT shelves provide standard mounting configurations for PG-Flex systems and support both 19-inch and 23-inch equipment frames. The 19-inch shelf may be equipped with a maximum of two systems and the 23-inch shelf may be equipped with a maximum of four systems. Line, channel, and alarm units are installed from the front of the shelf;...

    Figure 3. Four 24-Channel PG-Flex Systems (23” Shelf) Alarm Unit PG-Flex supports two types of Alarm units, the FAU-728 List 1 and the FAU-728 List 2. Both Alarm units provide PG-Flex Shelf interface to the CO Audio and Visual Alarms, and provide at least one test jack for line breakout functions (Looking-In, Looking-Out, Bridging).

  • Page 13: Pgtc Interface Unit

    COT Line Unit A PG-Flex system is comprised of one line unit and one or more channel units at both the CO and remote terminals. The COT line unit takes the CO battery and converts it to the voltages necessary to operate the COT line unit and channel units, as well as for powering the remote terminal.

    On hook transmission is provided to support CLASS services. The 8-channel POTS units for PG-Flex support eight analog interfaces at both the CO and RT locations. Three channel units are required for a 24-channel system. The channel units provide the following features: •...

  • Page 15: Isdn Channel Units

    The ISDN Basic Rate Interface (BRI) channel unit provides an interface to North American Integrated Services Digital Network (ISDN) basic access services (see Figure 4). Each ISDN channel unit for PG-Flex supports four “U” interfaces with provisionable sealing current and performance monitoring on each channel. Line termination (LT) in the CO occurs at the ISDN switch.

  • Page 16: Remote Terminal Equipment

    RT Enclosure One RT Enclosure is required for each PG-Flex system, and provides mounting for one common line unit and up to three (3) channel units, supporting up to 24 channels. The enclosures provide termination points for subscriber circuits, power, and metallic bypass pair. AMP Quiet Front™ or RayChem terminations, with internal gas tube protectors, are provided on the backplane for High bit-rate Digital Subscriber Line (HDSL) and Bypass connections.

  • Page 17: Rt Line Units

    Regardless of the number of channels being transported by PG-Flex, two copper pairs are required between the CO and the RT to support the HDSL transport and provide power to the RT. As shown in Figure 6, both pairs are used for simplexing the power between the COT and RT.

  • Page 18: Rt Channel Units

    Channel units provide the interface between subscriber services (POTS, ISDN) and the PG-Flex system’s internal pulse code modulation (PCM) bus. The RT channel units must be installed in the same relative slot positions as the channel units on the CO-end of a PG-Flex system. The RT channel units provide the following features: •...

  • Page 19: Subscriber Drop Testing

    For subscriber drop testing from the CO, PG-Flex is able to select and connect any subscriber drop to the metallic bypass test pair at the RT. PG-Flex extends this connection back to the COT where it switches onto the metallic access bus or to the corresponding subscriber line on the COT channel card.

  • Page 20: Metallic Bypass Pair

    When testing subscriber drops through the metallic bypass pair, the length and quality of the bypass pair must be taken into consideration when analyzing the measurement results. Only one subscriber circuit in a PG-Flex shelf can be accessed at a time when an FPI-729 List 1 or an FAU-728 List 2 is installed.

  • Page 21: Craft Port Access

    Subscriber Drop Testing Craft Port Access Using an ASCII terminal connected to the Craft port, the technician can access a specific subscriber drop. Instead of connecting the metallic bypass pair back to the local test system through the CO switch, the metallic connection appears on the PGTC interface or alarm unit test jack. As shown in Figure 9, this method of metallic access does not require a local test system and provides the technician with a means to perform metallic testing of the subscriber drop without traveling to the remote location.

  • Page 22: Alarms

    Major Alarm. Major Alarms occurring within the PG-Flex system are propagated up to the COT line unit. The Fault LED illuminates at the respective line unit nodes and also at the COT FAU/FPI indicating a Major Alarm condition.

  • Page 23: Faults

    Faults Faults A fault on any unit shall be an indication of an abnormal condition that affects the functionality or performance of the unit itself or any units under its control. That is, a fault on an RT channel unit shall be indicated on the channel unit itself, propagated to the upstream RT line unit, and reported as a fault against the RT channel unit.

  • Page 110: Pg-Flex Metallic Test Access

    Troubleshooting PG-Flex Metallic Test Access PG-Flex provides a break-out function and automatic line test support used to diagnose a faulty subscriber connection. Manual subscriber line metallic access is activated and deactivated via the Craft Port Interface. Test Desk support for 4TEL line testing is handled via recognition of control voltages to the Channel Under Test.

  • Page 111: Subscriber Drop Testing

    Using standard metallic access techniques and equipment, you can access a specific subscriber drop and have a metallic test path back to the Central Office test equipment. Only one subscriber circuit in a PG-Flex shelf can be accessed at a time when an FPI-729 List 1 or an FAU-728 List 2 is installed.

  • Page 112: Craft Port Metallic Access

    Troubleshooting Craft Port Metallic Access Subscriber drop tests are accessed through a terminal connected to the Craft port of the line unit front panel, or through the RS-232 interface on the PGTC Interface Unit (FPI-729 List 1) or Alarm Unit (FAU-728 List 2). Refer to Terminal Management for procedures on accessing the craft maintenance port.

  • Page 119: Hdsl Transmission Distance

    Troubleshooting Using Standard Test Equipment HDSL Transmission Distance The distance limitation for HDSL transmission is based on a maximum signal attenuation of 35 dB at 196 kHz. Since signal attenuation decreases as cable size increases, the larger the gauge (i.e., 19 AWG vs. 26 AWG), the greater the distance between the COT and the RT. Table 35 identifies these distances (at a cable temperature of 68°F).
