When used with the PG-Flex Plus , 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.
