Chapter 1 Understanding ISDN and the ISU 2x64 ISDN OVERVIEW The Integrated Services Digital Network (ISDN) is a public or pri- vate switched digital network. ISDN is an international standard for digital communications, allowing a full range of enhanced ser- vices 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

Chapter 1.Understanding ISDN and the ISU 2x64 The ISU 2x64 features two RS-530/EIA-232 DTE interfaces and two RS-366 dial interfaces (see Figure 1-1). An RS-530/EIA-232- to-V.35 adapter is available to support V.35 DTE interfaces. Syn- chronous data transfer rates from 2400 bps to 128 kbps and asyn- chronous rates from 1200 bps to 115.2 kbps are supported on a single DTE interface. Synchronous data transfer rates from 2400 bps to 64 kbps and asynchronous rates from 1200 bps to 57.6

Chapter 1. Understanding ISDN and the ISU 2x64 The ISU 2x64 allows the user to migrate ISDN into existing net- work services and data communications equipment. The ISU 2x64 interoperates with ISU 128s, Switched 56 DSUs, various ISDN terminal adapters, and BONDING inverse multiplexers (for example ASCEND®, PROMPTUS, and Teleos®). For instance, in a video conferencing application, this compatibility allows the ISU 2x64 to interoperate with networks utilizing two Switched 56 DSUs.

Chapter 1.Understanding ISDN and the ISU 2x64 When the ISU 2x64 is used on an existing ISDN line that is not multipoint, with one SPID or no SPID numbers, additional con- siderations should be addressed. If DTE specific operation is desired, the ISDN line must be converted to multipoint operation (2 SPIDS). If not, the following applies: 1. If a single SPID is assigned, it must be entered under SPID DTE#2. 2. When no calls are active, the first incoming call is always di-
