PG-Plus
Subscriber Carrier
System
PG-Plus® is a cost-effective subscriber carrier system that derives 2, 4, or 6 lines from a single
copper pair. ADC’s proven HDSL transmission technology provides reach 20% beyond that of
traditional Digital Added Main Line (DAML) solutions.
PG-Plus installs in minutes due to line powering and its plug-and-play design. Its unique
architecture supports POTS, UVG, DDS, ISDN, P-Phone, CLASS features, enhanced MLT
testability and network management all from the same platform. PG-Plus supports universal
and integrated mode connections to the local switch allowing deployment from the CO or
remote cabinets. Integrated mode enables feeder and distribution relief whereever DS1
bandwidth can be extended and makes an excellent tool for supporting 56 kbps modems.
Features:
• Line-powered remote terminal
• Two-, four- and six-channel systems
• Flow-through provisioning
• HDSL 2B1Q transmission over
unconditioned copper loops
• POTS, ISDN, DDS, P-Phone, UVG and more
• TR-008 and D4 integrated modes
• 56 kbps modem support
• Metallic fallback operation
• Low maintenance, single ended turn-up
• System software downloads to RTs
• NEBS Level 3 compliance
• Feeder and distribution
• Emergency and temporary services
• Internet services
• Residential, SOHO and business services
• Mixed POTS and data services
