The DMS-500 Local and Long Distance Switch is a SuperNode application that combines local services of the DMS-100 switch, toll and operator services of the DMS-100/200 Traffic Operator Position System (TOPS), and long distance services of the DMS-250 switch. In addition to the trunk connections supported by the DMS-250, the DMS-500 delivers all line types currently supported by the DMS-100 system for residential and business applications.

• Ability to quickly generate new revenue through new services, new markets, and new end-to-end telephony offerings

• Maximum market flexibility for service providers:
  • selling or reselling long distance services
  • operating with or without operator services
  • offering business and residential line services
• Cost and operational efficiencies gained in combining DMS-100/200 and DMS-250 services:
  • reducing front-end hardware requirements
  • reducing office site and environmental requirements
  • centralizing operations, administration, maintenance, and provisioning (OAM&P)
• Expanded pre- and post-sales service support to build a network, train the staff, and operate the network, if needed
• Multi-vendor network operability ensured with the DMS-500 SuperNode system's open architecture
