Integrated Services Digital Network (ISDN) is part of the evolving end-to-end digital telecommunications network architecture which provides for the simultaneous access, transmission and switching of voice, data, and image services via channelized transport facilities over a limited number of standard user-network interfaces.

Integrated Services Digital Network (ISDN) is available from Ironton Telephone for both Business and Residential customers. ISDN is available as a Basic Rate Interface (BRI) or a Primary Rate Interface (PRI). Basic Rate Interface (BRI) provides two bearer (B) channels of 64Kbps each and a data (D) channel at 16Kbps. The two B channels are used for voice, video, or high speed data while the D channel is used for Signaling and low speed data transmission. Also commonly known as 2B+D.

Primary Rate Interface (PRI) provides 23 bearer (B) channels of 64Kbps each and a Data (D) channel at 64Kbps. This is the ISDN equivalent of a T-1 delivered to a customer's premise. Also commonly known as 23B+D.
