DEFINITY Enterprise Communications Server and System 75 and System 85 Terminals and Adjuncts Reference 555-015-201Issue 11 December 1999 Data Modules 21-45 The 703A Data Service Unit (DSU) 21 The 703A Data Service Unit (DSU) Figure 21-14. The 703A Data Service Unit The 703A DSU is used with the 7406D voice terminal to provide asynchronous data communications through the switch. The DSU replaces the desk stand under the 7406D voice terminal and allows a data terminal (such as a 610 BCT) to be connected to the 7406D and data calls to be made to and from the switch. (See Figure 21-15.)

The DEFINITY High Speed Link The DEFINITY HSL is a data service unit that allows data equipment to access the data services of System 75 and System 85 and the DEFINITY switch. It is used where the integration of voice and data is not required. The HSL suppor ts synchronous data transmission at speeds of 56 and 64 kbps, and provides a link to high speed data networks. The DEFINITY HSL provides access to various switched and dedicated (private) data networks, including Group 4 Fax, Video Teleconferencing, LAN Interconnect, and Cluster Controller/Front-End Processor Connections.

Display This 16-character LCD display shows the star t-up sequence, status, option information, and test information. NEXT/NO, BACK, and ENTER/YES buttons These buttons are used to step forward and backward through the menus. These buttons are also used for executing functions.

Routing, trunking and other administration considerations mirror those of the MPDM. The uses of the DEFINITY HSL are compatible with those of an MPDM. Switched Requirements The following sections describe switched requirements. Releases for Switched Applications The switch releases which support the applications of the DEFINITY HSL are: nSystem 75 R1V2 or later nSystem 85 R2V3 or later nDEFINITY Generic 1, Generic 2, and Generic 3 nDEFINITY ECS All versions of the switch do not provide the same level of suppor t. The biggest difference is in the type of network access arrangement that is suppor ted.
DEFINITY Enterprise Communications Server and System 75 and System 85 Terminals and Adjuncts Reference 555-015-201Issue 11 December 1999 Data Modules 21-53 The DEFINITY High Speed Link 21 Switched Endpoints The DTE must be capable of communicating at 56 kbps or 64 kbps. Proper switched operation requires that the DTE supports a Data Terminal Ready (DTR) lead on its V.35 interface. The DTR lead provides the signal to the HSL that it is ready to receive or originate a call. Before the High Speed Link can originate (dial) or answer a call, the DTR lead must be asser ted (high) by the DTE. In addition, the DTE uses the DTR lead to signal the HSL to drop a call. This is accomplished by turning off its DTR lead. Switched Applications Switched applications are applications using the switched network. ACCUNET Switched Digital Services (SDS) and Software Defined Data Network (SDDN) are examples of switched applications. See Figure 21-17 for an example of a switched configuration. For additional information on switched applications, implementations, and administration, refer to the DEFINITY High Speed Link User’s Manual , 555-020-711, Appendix D: Applications and Switch Administration.

DEFINITY Enterprise Communications Server and System 75 and System 85 Terminals and Adjuncts Reference 555-015-201Issue 11 December 1999 Data Modules 21-54 The DEFINITY High Speed Link 21 Permanent (Private Line) Requirements The following sections describe Permanent (Private Line) requirements. Releases for Permanent Applications Permanent applications require the switch to establish and maintain the connection. The switch release and corresponding feature that suppor t permanent connections are: nSystem 75 R1V2 or later - Permanent Switched Call (PSC) nSystem 85 R2V4 or later - Dedicated Switch Connection (DSC) nDEFINITY Generic 1 - Administered Connection (AC) or Permanent Switched Call (PSC) nDEFINITY Generic 2 - DSC nDEFINITY Generic 3 and the DEFINITY ECS - AC These various switch features provide different levels of suppor t for permanent applications. The DEFINITY G3 and DEFINITY ECS provide the broadest level of suppor t with the Administered Connection Feature. The Permanent Switch Call in System 75 and DEFINITY G1 and the Dedicated Switch Connection in System 85 and DEFINITY G2 provide a subset of that functionality. Permanent Endpoints If DTE does not suppor t the DTR lead, then the DTR IGNORE option must be used. This will allow a permanent connection to be established and maintained. Permanent Applications A permanent connection uses a DS0 channel on a private T1 between sites, or a DS0 channel on a DS1 to a private digital network such as ACCUNET Spectrum of Digital Services (ASDS). See Figure 21-18 for an example of a Front End Processor/Cluster Controller application in a permanent connection configuration. For additional information on permanent applications, implementations, and administration, refer to the DEFINITY High Speed Link User’s Manual, 555-020-711, Appendix D: Applications and Switch Administration.
