isdnIntegrated Service Digital Network Primary Rate Interfaces are configured with 23 bidirectional channels and one data channel and facilitate transmission speeds of up to 1.5 megabytes per second. Additionally, ISDN PRIs offload all signaling and call control requirements onto D channels, leaving the remaining B channels free for data, voice or a combination of the two services.

Unlike analog trunk lines, ISDN PRIs also include caller ID delivery and all-digital technology that allows for simultaneous, integrated voice and data capabilities over standard telephone lines and PBX phone systems.

We offer affordable ISDN PRI packages that come with an array of value-added features, including:

  • Assignable direct inward dialing numbers for workstation or desks.
  • T1-enabled voice and data access.
  • Call center and PBX system support features.
  • Customizable channels.
