Qwest DS-3 SHARP with a Central Office MUX (Customer Provided Access to IXC)

Case Study – Upgrade from IXC provided DS-1 access to fiber based Self Healing DS-3 providing DS-1 port access to multiple IXC’s

Customer Background

  • A leading provider of electronic payment and loyalty services. Processing transactions initiated for over 50,000 sites and over 70,000 point-of-sale systems across North America by credit, debit, EBT, proprietary, prepaid, fleet, checks and loyalty cards from stand-alone point-of-sale (POS) terminals, electronic cash registers, pump dispensers and unattended cardlocks systems
  • This customer operates two geographically separated data centers. All client transactions have both data and processing redundancy to ensure maximum system reliability and availability. Over the past six years, these redundant processing centers have had system availability exceeding 99.9%, surpassing industry standards
  • This customer had traditionally used IXC 800 service provided DS-1 access. The DS-1’s were provisioned on copper and did not have diversity (or self healing) from the customer’s serving wire center to the customer premise

Customer Need

  • Highly survivable DS-1 access to multiple IXC’s for Toll Free (800) service from the customer location in Plymouth, MN

Solution

  • Qwest DS-3 SHARP with a Central Office MUX in the Downtown Minneapolis Wire Center & DS1 Cross Connects to IXC DS1 ports
  • Monthly Recurring Charge $2,488.50. Less than $90.00 monthly per DS-1 port
  • SHARP is an optional feature and function on DS-1, DS-3 and Synchronous Service Transport (SST) Private Line Service that protects the channel termination or local loop and is transported over fiber-optic facilities. This feature provides a separate facility path for the protection system between the serving wire center (SWC) and the point of termination (POT) located in the same building as your customer-designated premises, when your customer or building owner provides the structure for diverse entrance facilities into the building
  • This added protection is provided by ensuring that backup electronics and two physically separate facility paths are used in the provisioning of the service. A primary (or working) service path is established between the SWC and the customer-designated premises. A secondary (or protect path) is provisioned between the customer designated premises and the SWC via a Company designated alternate wire center (AWC) when available. Due to constraints of the local network architecture, there may be occasions where the service will be provisioned without the use of an AWC
  • Should the working path or electronics fail, or the service performance becomes impaired, i.e., the bit error rate degenerates to less than or equal to 10 to the minus 6, the service will automatically switch to protect to maintain a near continuous flow of information between locations
  • The original DS-3 SHARP system was implemented in 2001. The customer is now implementing additional DS-3 SHARP systems

Results & Benefits

  • Customer controlled, cost effective, highly survivable DS-1 access to many IXC’s with points of presence in downtown Minneapolis
  • The customer, purchasing services at the DS-3 level, could negotiate for diverse fiber placement to be funded. An IXC would not have been able to cost effectively negotiate with Qwest for diverse fiber placement for less than a DS-3 capacity of service
