PG-Flex
Plus
™
is a revolutionary new subscriber carrier platform that enables the cost-effective
deployment of multiple voice and data services over single or dual pair DSL transport
technology. The PG-Flex
Plus
system is comprised of a central office terminal shelf, 4 or 6 line
PG-Plus® NIDs, a 24/48 line PG-Flex® Remote Enclosure and an optional Universal Access
Platform (UAP) GR-303 concentrator shelf. This system can be used in a variety of applications
that will enable more efficient use of network facilities including:
• Copper pair relief in the feeder and distribution network
• POTS and data service extensions over unconditioned pairs
• Support for future growth including HDSL2 transport and ADSL G.Lite service

can provide incremental network capacity. PG-Flex RTs can be placed at existing copper fed cross
connect cabinets to provide 24/48 lines to the F1 side of the box. This incremental addition of capacity will

enable many sites to support added lines for several years.
“Help To The House”
PG-Flex
Plus
RTs are deployed on the side of a home or small business. The existing copper pair that provided a
voice circuit will now provide up to 6 POTS lines, ISDN or DDS. This additional network capacity will provide
pair relief back to the central office.
“Plumb The Network”
As ADSL services are introduced into the network, PG-Flex
Plus
can assist with several issues. Additional lines
strain the capacity of an existing copper network, and PG-Flex
Plus
can free up pairs that can be reused for ADSL
service.
56K Modem Support
Since PG-Flex
Plus
offers both a TR-008 or GR-303 digital interface to the switch, high-speed modem support is
possible as a result of the elimination of one analog-to-digital conversion.
Integrated Mode
PG-Flex
Plus
central office equipment is designed with a digital (DS1) switch interface. This interface can be
provisioned as TR-08/D4 for incumbent networks or GR-303 for developing networks.
Deployment Flexibility
Since PG-Flex
Plus
central office equipment is environmentally hardened, it can also be deployed out in the
network subtending DS1 tributaries from high-speed muxes or fiber-based terminals. As a result, pair gain can

be achieved further into the network. Integrated PG-Flex
Plus
Line Units are also being developed that can be
retrofitted into standard T1 repeater housing mechanics.
Relief To The F1 Network
Facility Relief provided to Cross
Connect by creating 24 new F1
cable pairs from two. Typical
installations will include 24 to 48
additional new lines.This additional
capacity may provide two or more
years of network capacity.
Relief To The F2 Plant
Each PG-Flex
Plus
access shelf placed
in a RT cabinet will provide up to
192 lines. This new capacity will
allow the cross connect box and F2
cable to have an extended life.
