The PG-Flex 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.

ESCRIPTION AND
To support the DICOLU, a PG-Plus

PG-Flex Multiplexer Unit (PMX) must be installed in the PG-Flex

Switch
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
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
transmission and line powered RTs results in fast, cost-effective solutions to subscriber service deployment over
existing copper facilities.
