PG Flex Subscriber Carrier System.qxdmicro-DLC System
ADC's PG-Flex micro-DLC provides feeder (F1), distribution (F2) or
drop "pair relief" in areas of the network suffering from copper
pair shortages. It enables Local Exchange Carriers (LECs) to
quickly and cost-effective- ly meet held order demands for POTS or
ISDN services in these areas. PG-Flex is a far superior alternative
to expensive and time consuming alternatives of cable rearrange-
ments, laying more cable or installing a large capacity Digital
Loop Carrier (DLC) system.
The PG-Flex micro-DLC is a highly versatile platform supporting
both indoor and out- door pair relief applications. Remote termi-
nals (RTs), which are deployed in 24-channel increments, are
available in 24, 48 and 96- channel configurations. Outside plant
hard- ened enclosures include 24/48-channel ver- sions with
complete lightning protection for installation at crossboxes or
existing
DLC/SLC cabinets. Indoor RTs, available in 24/48/96-channel
versions, provide a cost- effective alternative to standard D4
channel banks. All PG-Flex remotes are line-powered reducing the
need for costly batteries and UPS systems.
Features:
• Traditional HDSL transmission architecture • 24-channel system
architecture • Extended temperature rating • Supports POTS and ISDN
services • Supports MLT testing (TR-909) • Indoor and outdoor
specific remotes • TR-57 (VF) switch interface • Supports
crisis/temporary service needs
