OVERVIEW
The PG-Flex®FRL-842 List 1C 24 Channel Remote Terminal (RT) Line Unit is located in a RT Enclosure. The
system uses High-bit-rate Digital Subscriber Line (HDSL) 2B1Q technology to transport 24 DS0s of Plain Old
Telephone Service (POTS) and Integrated Services Digital Network (ISDN) services between the
FLL-812 Universal Central Office (CO) Line Unit or the FLL-814 Integrated CO Line Unit and the FRL-842. The
FRL-842 is line powered from the Central Office.
The FRL-842 L1C RT Line Unit is compatible with the FLL-814 L1A and L2 or later CO Line Units. The
FRL-842 L1C cannot be used in conjunction with the FLL-814 L1 CO Line Unit unless the application
software on the FLL-814 L1 has been upgraded to 2.X or later.
If a single CO Line Unit or RT Line Unit has to be replaced, the new card does not have to be reconfigured
because the existing settings are maintained.
All screens in this manual were captured with an Integrated FLL-814 installed in the COT; therefore, the
screen banners and System ID reads PG-FLEXPLUS. When viewing screens with a Universal FLL-812
installed in the COT, the screen banners and System ID reads PG-FLEX.
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 FRL-842 through the Management Unit.
!
IMPORTANT Please refer to Appendix A on page 133 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 software compatibility information.

DESCRIPTION
When used with the PG-FlexPlus, a typical integrated system configuration is comprised of a FLL-814 in the CO, one
FRL-842 and three RT Channel Units at the RT (Figure 1). Up to eight integrated systems can be supported in a
PCS-719 Central Office Terminal (COT) Shelf. A management unit, common to all systems installed in the COT
Shelf, provides an interface for alarm relays and testing of subscriber circuits. A multiplexer card takes the DS0s
from the system and converts them to D4, ESF, or TR-08 DS1 signals at DSX-1 levels.
When used with the PG-Flex, a typical universal system is comprised of one line unit and three channel units at both
the COT and RT (Figure 2). The FCS-719 COT shelf supports up to four systems. The channel unit card in the COT
must be the same type of slot specific card (POTS or ISDN) as the channel unit 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.
The remote end of either system type is housed in a RT Enclosure. RT Enclosures are designed for indoor and
outdoor applications and are provided with a diverse selection of mounting options. These RT Enclosures support
one or more systems that include one FRL-842 and up to three RT Channel Units for each system.

FUNCTIONS AND FEATURES
The FRL-842 provides the following functions and features:
• Line powered from FLL-812/FLL-814
• HDSL line transceivers and power supply
• Front panel status indicators
• Downloadable firmware
• Environmental Alarms
• Support for FFU-865 (Fan Card) and associated alarm
• Mechanized Loop Test (MLT) test system compatibility
– TR-909
– Bypass
MLT components include bypass pair and TR-909 type testing. In TR-909 mode, an internal test head for
determining the condition of the subscriber drop calculates the results and inserts TR-909 resistive signatures for
MLT to read.
SUBSCRIBER DROP TESTING
The FRL-842 supports subscriber drop testing using an internal test head that eliminates the metallic bypass pair.
This test head reports its results through the Flex PGTC Interface Unit (FPI-829) (for universal systems) or
management unit (for integrated systems) using three-terminal signature resistors that are measured by MLT and
converted to subscriber drop condition messages that can be viewed on the VT-100 terminal as described in TEST
— Subscriber Drop Test on page 121.
Subscriber Drop Testing is not available on the FPI-729, FLL-712 or FRL-742.

HDSL TRANSMISSION
The system uses HDSL 2B1Q technology to transport 24 DS0s plus signaling over two copper pairs. The HDSL
circuits can be used without repeaters or loop conditioning. Adaptive equalization, scrambling, and a four-level
2B1Q line coding scheme are used to maximize distance and minimize crosstalk.
Table 1 shows the maximum distance between the COT and RT for various wire gauges with or without doublers in
the circuit. These distances are shown for a cable temperature of 68º F (20º C). As the temperature of the cable
increases, the distance decreases.

When the RT is powered from the COT, two auxiliary power pairs are required between the COT and RT
for each doubler installed in the HDSL circuit. Refer to the COT Shelf or RT Enclosure technical practice
for additional information on the power pairs.
