What is ISDN?
ISDN stands for Integrated Services Digital Network. With ISDN, customers access the Allstream service through an ISDN Basic Rate Interface (BRI) line that is leased from their local phone provider. ISDN access offers speeds up to 128Kbps through a two-channel BRI line. The versatility of this option allows customers to choose how they are going to use the access – they can decide to apply the full speed toward their Internet connection or they can split the functionality between the two 64Kbps channels to accommodate voice and data traffic as well.
(Integrated Services Digital Network) This is a special telephone line that guarantees a connection speed of 64K. An ISDN line automatically connects whenever the user sends information requests to Wave Rider, and automatically disconnects when the data transfer is complete. Call costs are still applicable when using this service.
ISDN (Integrated Services Digital Network) is an all-digital communications network designed to bring the power of the digital network directly to the desktop. It is the ideal communications technology for the information age – perfect for students, cyberspacers, travelers, telecommuters, parents, business people, and corporate executives.
ISDN stands for Integrated Services Digital Network. It is a communication protocol defined by CCITT/ITU-TSS for telephone network to carry data, voice and other sources. ISDN is delivered from a digital switch through two types of user interfaces: the Basic Rate Interface (BRI) and the Primary Rate Interface (PRI). Each consists of two numbers of 64Kbps bearer or B channels, coupled with one data, or D channel. B channels are 64Kbps clear-channel connections, and can be used for dial-up voice and data connections. The D channel is defined as a packet-switched call set-up and signaling connection shared by all users of ISDN. Basic Rate Interface is defined as two 64Kbps Bearer (B) channels and one 16 KBPS Data (D) channel that carries both call set-up and users data packets across the network. The BRI interface is also referred as a 2B+d connection. BRI can carry a wide and flexible range of communications.
