Wholesale Digital Access - ISDN30

ISDN (Integrated Services Digital Network) channels are, in effect, digital exchange lines. They allow the digital transmission of voice and data over ordinary copper telephone wires, bringing better voice quality and quicker data transfer speeds. ISDN30 comes in two variants; ISDN30e (the 'e' stands for European Telecommunications Standards Institute or ETSI signalling system), and ISDN30 DASS (Digital Access Signalling System).

Usually better suited to medium or large business customers, ISDN30 enables you to create and launch your own-branded digital telephone services. It provides access and support calls, including calls over the networks of other communications providers.

Key benefits:

  • Secure, dedicated, high-bandwidth connectivity similar to a private circuit service
  • Resilience options to keep your customers' connected
  • Take advantage of flexible number configurations helping manage end customers’ calls efficiently
  • Access to a full range of calling and network features, including debt management and fraud services
  • Common signalling standards enabling private circuits to be extended
  • Transmit voice, data, text and applications such as video-telephony all in one circuit, to help improve efficiency
  • Enhance your existing ISDN service, seamlessly upgrading from ISDN2 for additional functionality
