OVERVIEW
The PG-Flex®FLL-812 List 1A 24 Channel Universal Central Office (CO) Line Unit is located in a PG-Flex Central
Office Terminal (COT) Shelf. The PG-Flex system uses High-bit-rate Digital Subscriber Line (HDSL) 2B1Q
technology to transport up to 24 DS0’s of Plain Old Telephone Service (POTS) and Integrated Services Digital
Network (ISDN) service between the FLL-812 and a PG-Flex FRL-842 Remote Terminal (RT) Line Unit. The RT Line
Unit can be line-powered from the COLU or locally powered.
DESCRIPTION
The universal system is comprised of a line unit and channel units at both the COT and RT (Figure 1 on page 2).
Line units and channel units can be hot-swapped without affecting other systems in the same shelf. The POTS
channel units support dial-up modem and group 3 facsimile on all channels.
The COT shelf supports up to four systems, where each system is comprised of one COLU and up to three Central
Office Channel Units (COCUs). The channel units must be the same type of card (POTS or ISDN) as the channel
units installed at the RT. A PG-Flex FPI-829 Pair Gain Test Controller (PGTC) Interface Unit (common to all systems
installed in the shelf) provides an interface for maintenance, alarm relays, and metallic access to the remote
subscriber lines.
RT enclosures support up to four systems, where each system is comprised of one RT Line Unit and up to three
PG-Flex Remote Terminal Channel Units (RTCUs). The channel units must be the same type of card (POTS or
ISDN) as the channel units installed at the COT. RT enclosures are designed for indoor and outdoor applications
and are provided with multiple mounting options.
The FLL-812, in combination with the FRL-842, eliminates the need for a metallic bypass pair for subscriber drop
testing by using a test head in the FRL-842. Results of subscriber drop tests are reported back to the central office
test equipment through the FPI-829 with three-terminal resistive signatures complying with TR-NWT-000909
specifications. The FLL-812 and FRL-842 can optionally be configured to support the metallic bypass pair instead of
using the test head..
If an FPI-729 is installed in the system, craft sessions must be initiated through the front of the FLL-812
because craft sessions with the FLL-812 are not supported through the FPI-729. However, if an FPI-829 is
installed in the system, you can log into the FLL-812 through the FPI-829.
The FLL-712 and FLL-812 COLUs can reside in the same COT shelf and function normally. FLL-812 alarm
reporting is compatible with the FPI-729; however, the FLL-812 critical alarms are mapped to the FPI-729
major alarms. The FLL-812 is not compatible with the FAU-728.
All references to a VT-100 terminal imply that a Personal Computer running VT-100 terminal emulation
software can also be used for accessing the COLU through the Management Unit.
!
IMPORTANT Please refer to Appendix A on page 139 to facilitate proper system configuration. The Feature
Matrix identifies the major features in the CO and RT line units. The Compatibility Matrix provides
CO and RT line unit compatibility information.

FUNCTIONS AND FEATURES
The FLL-812 provides the following functions and features for each 24-channel system in a single COT shelf:
• HDSL line transceivers and power supply
• Front panel status indicators
• Front panel craft terminal interface
• Downloadable software for product maintenance
• Eliminates the requirement for a metallic bypass pair (though supported when needed) for subscriber drop testing
If the FLL-812 is connected to an FRL-842 List 2, the power pairs (as shown in Figure 1) will not be needed
since the FRL-842 List 2 is locally powered.

HDSL TRANSMISSION
The FLL-812 card uses HDSL 2B1Q Technology to transport 24 DS0s plus an operations channel for management
control over two copper pairs. Adaptive equalization, scrambling, and a four-level 2B1Q line coding scheme are
used to maximize distance and minimize crosstalk.
The line interface is a two-pair, 784 Kbps full-duplex 2B1Q transmission format. The signal characteristics on the
carrier pairs comply with TR-NWT-001210, Generic Requirements for HDSL Systems.
Table 1 shows the maximum distance between the COT and the RT for various gauge wire with up to two doublers
in the circuit. Because of HDSL transmission technology, the HDSL pairs require no special conditioning and may
include unterminated bridge taps; however, they cannot include load coils.
Table 1. HDSL Distances
When the RT is powered from the COT, two auxillary power pairs are required between the COT and RT for each
doubler installed in the HDSL circuit. These power pairs should meet the same criteria as the HDSL pairs. Refer to
the COT Shelf and RT Enclosure technical practices for additional information on the power pairs. The RT can also
be locally powered to eliminate the need for auxiliary power pairs.
SEALING CURRENT
The FLL-812 provides line powering voltage even if the RT Line Unit is locally powered. In this configuration, the
locally powered RT Line Unit draws no current on the HDSL pairs. In order to allow the operating company to “wet”
the HDSL lines, the locally powered RT Line Unit provides a provisionable sealing current load circuit. This feature is
provisionable as ENABLED or DISABLED. The default is DISABLED. Refer to CONFIG — System Options section
for a description of provisioning the sealing current feature.
DISABLED
If a single span system is used, no current flows in the span between the RT and the COT. If doublers are used, no
current flows in the span between the last doubler and the RT. Current does flow in the spans between the CO and
doublers since the doublers are still line powered.
ENABLED
The Sealing Current load is automatically applied for a period of 15-20 seconds, once every 24 hours at the system
clock time of 00:05. A minimum of 20 mA is drawn through each conductor of HDSL (side 1 + side 2) during the time
the sealing current feature is active. The current flow is ramped at a rate less than 20 mA/second to meet industry
standard requirements for pulsed sealing current.

SUBSCRIBER DROP TESTING
Test results on POTS subscriber drops can be displayed through a maintenance screen during a craft session or as
three-terminal resistive signatures (compliant with TR-909) reported back to the MLT system through the FPI-829.
Wire the PG-Flex COT Shelf to the FPI-829 per local procedure. Table 2 shows the signature resistances that are
presented to the CO test system for various line conditions.

The resistive signatures on the FPI-829 List 3 are biased to -14 Vdc.
The resistive signatures shown in Table 2 are typical. Refer to the FPI-829 technical practice for specific
resistive signatures provided by the various models of the FPI-829.
The FLL-812 can be configured to use a metallic bypass pair for subscriber drop testing in cases when MLT
does not support TA-909 resistive signatures.
