Feeder Relief

Situation

Adding new voice service to exhausted rural cable routes, presents Local Exchange Carriers (LECs) with a unique set of challenges where (1) an immediate service order response is needed and (2) the demand for service, along the typically “long thin” rural route, does not justify extensive cable rearrangements, cable placements or a Digital Loop Carrier (DLC) installation Additionally, LECs must also ensure that any solution they deploy to meet these challenges must also be capable of delivering ADSL in the rural environment

Solution

The PG-FlexPlusField Shelf allows LECs to meet their voice service demands on rural routes at distances

of up to 144kft using HDSL service feed and greater distances using traditional T1 service feed The PG-FlexPlusField Shelf’s unique distributed facility relief architecture allows telcos to easily meet their demands for new services on long thin cable routes while solving underlying feeder, distribu-tion, and drop challenges The PG-FlexPlusField Shelf is an environmentally hardened system in out-side plant friendly packaging Each PG-FlexPlusField Shelf can deliver up to 96 voice lines to a wide range of line powered remote enclosures

The PG-FlexPlusField Shelf architecture also supports delivery of extended reach ADSL to remote areas

of the rural network

Result

• Immediate servicing of held orders

• Solve underlying feeder, distribution and drop problems

• Avoid expensive feeder cable reinforcement or rearrangments

• Provide voice services that support V.90 modems

• Deliver ADSL service with the PG-FlexPlusEdge RAM and Edge IAD

Implementation:

Field Shelf:

The PG-FlexPlusField Shelf supports standard (212 mechanics) T1, HDSL, or HDSL2 interface cards and provides a D4 or TR-08 interface to the DLC or Class 5 switch The Field Shelf may be located on a long thin route where a DLC cabinet or crossbox may be in place The field shelf is pole, wall or pedestal mounted and locally powered

Remotes:

Once the PG-FlexPlusField Shelf is in place, installation of the remotes is simple Most remotes can be physically installed in less than 4 hours Each PG-FlexPlusField Shelf can subtend 24-channel remotes,

or 4/6 channel remotes or a combination of both Each remote is line powered, and is available in indoor and outdoor versions The PG-FlexPlusField Shelf can also subtend Edge RAM and Edge IAD remotes to deliver ADSL service in the rural environment

Distributed facility relief architecture with PG-FlexPlus

The PG-FlexPlusField Shelf allows telcos to extend voice services without adding additional cable By fully utilizing the existing copper network, service can be delivered much more cost effectively The field shelf can be placed alone or adjacent to an existing DLC The example above demonstrates the service delivery distances over 22 AWG
