The PG-Flex
Plus ™
PLL-735 is a Dual Integrated Central Office Line Unit (DICOLU) that drives two Remote
Terminals (RTs) to provide for Plain Old Telephone Service (POTS), Integrated Services Digital Network
(ISDN), and Universal Voice Grade (UVG) subscriber services.

EATURES
To support the DICOLU, a PG-Plus
®
Alarm Unit (PAU) or PG-Flex
Plus
Management Unit (PMU) and a
PG-Flex
Plus
Multiplexer Unit (PMX) must be installed in the PG-Flex
Plus
Central Office Terminal Shelf (COTS).
Figure 1, “Typical IDLC Configuration,” on page 1 , illustrates the components of a PG-Flex
Plus
system. When
operating in the IDLC mode, the RT determines the type of services being supported.
Figure 1. Typical IDLC Configuration
The PG-Flex
Plus
system provides bidirectional transport of multiple DS0s over a single, unconditioned wire pair
using High-bit-rate Digital Subscriber Line (HDSL) technology. Using existing cable, PG-Flex
Plus
provides for
higher bandwidth needs of residential and business customers by providing multiple subscriber services on a
single twisted-pair wire.
Each DICOLU is installed in the COTS and interfaces with two corresponding RTs. Digital lines from the Central
Office (CO) connect to the COTS and are sent by means of the DICOLU and the HDSL wire pairs to the two RTs.
As an example, a 23-inch COTS can interface with 32 different RTs providing 6 POTS lines each, for a total of
192 subscriber lines. The COTS operates on standard -48 Vdc CO battery and supplies power to the RT over the
HDSL pairs, eliminating the need and expense of providing local power. A PG-Flex
Plus
system with HDSL
transmission and line powered RTs results in fast, cost-effective solutions to subscriber service deployment over
existing copper facilities.
