Quick Start Guide TM Before configuring the ISU 512, the telephone service provider must supply the switch type, service profile identifier (SPID), and local directory number (LDN). For example, for one ISDN BRI 2B+D line: Switch Type National ISDN-1 SPID1 20455512120100 SPID2 20455512130100 LDN1 5551212 LDN2 5551213 To configure the ISU 512 from the front panel press Enter from the initial sta- tus screen and continue entering the appropriate numbers until the Switch type,

Press Cancel to exit to the status screen and verify Ready conditions for each BRI line configured. If the status screen reads SYNC, DOWN, TEI, or SPID, either the configuration of the switch type and SPIDs are incorrect or there may be a problem with the ISDN line or translations; see the chapter Trouble- shooting. Outside of the U.S. and Canada, only the LDNs will need to be en- tered. Service Profile/ Line Maximum Directory Number Interface Bandwidth SPID1/LDN

Chapter 1 Understanding ISDN and the ISU 512 ISDN OVERVIEW The Integrated Services Digital Network (ISDN) is a public or private switched digital network. ISDN is an international standard for digital communica- tions, allowing a full range of enhanced services supporting voice, data, and image applications through standard interfaces over a single pair of telephone wires. ISDN provides a means of integrating these services and modernizing communication networks for information mo

Chapter 1: Understanding ISDN and the ISU 512 The ISU 512 transmits data over an RS-530 or V.35 interface, selectable from the front panel. The ISU 512 performs at synchronous data transfer rates of 56 kbps to 512 kbps. At rates over 64 kbps, the BONDING Mode 1 inverse mul- tiplexing protocol synchronizes data over up to eight 64 kbps B channels. By supporting BONDING, the ISU 512 interoperates with other BONDING-com- patible inverse multiplexers and ISDN terminal adapters. The I

Chapter 1: Understanding ISDN and the ISU 512 ISU 512 INTEROPERABILITY Telephone networks are evolving from analog technologies to digital technol- ogies such as ISDN. This transition is time-consuming and costly for tele- phone companies and upgrading all locations and facilities is a lengthy process. The ISU 512 bridges this transition by supporting communications with exist- ing and future network services and equipment. The ISU 512 supports com- munications with Switched 56 (SW56)
