PC Interface Issue 3 March 1996 3-947 1 and 2 can b e used b y administering them as an alias. Use terminal type BCT 510D for Release 2, Versions 2 and 3. Use 7405D with display module for Release 2, Version 1 switches. Wit h DE FI NITY system Generic 3, the feature name is changed to PC Interface to avoid confusion with the PC/PBX Connection software package which is part of the overall offering. PC Interface Group 3, the ISDN-BRI version of this feature, is first available on DEFINITY system Generic 2.1. The PC/ISDN Platform (Group 3) cannot be used with System 85 switches. User Operations User operations d e pend on the software used with the PC. For specific user operations, refer to the a p propriate PC Interface documentation set as follows: n555-016-715, PC/PBX Connection Documentation Set for the DCP versions (Groups 1 and 2) using the PC/PBX Connection software package. n555-016-101, PC/PBX Platforms Installation and Reference manual for PC/PBX Platforms. n555-016-102, PC/ISDN Platform Installation and Reference Manual for the PC/ISDN Platform (Group 3). Considerations nUse of Speakerphones Mo st DEFI NIT Y syst em Generic 3 sp eakerphones can be used with the PC Interface. nFunction Key Mo dule The Function Key Mo dule of the 7405D can be used with the PC Interface feature. nSPID (Service Profile Id entifier) On the DEFINITY switch Generic 3, BRI terminals are normally ‘‘initializing terminals’’ and require that a SPID be assigned ( see the Integrated Services Digital Network (ISDN) — Basic Rate Interfac e (BRI) feature). The PC/ISDN Platform (Group 3), in a stand alone configuration (no associated voice terminal), is a ‘‘non-initializing BRI terminal.’’ A non-initializing terminal does not require a SPID. When the PC/ISDN Platform is assigned as a stand alone non-initializing terminal, it is administered using a locally defined terminal type with General Terminal Administration, Procedure 50, Word 1 (see the Administration Procedures Manual , 555-105-506). When this is done, the terminal type is defined as a non-initializing terminal that does not supp ort MIMs (Management
Feature Descriptions 3-948Issue 3 March 1996 Information Messages). This requires a value of ‘‘0’’ in field 6 of Procedure 50, Word 1. Other specific characteristics of the locally defined terminal type will depend on the telephone manager applications software used with the PC. The PC/ISDN Platform can also be assigned with an associated (initializing) ISDN-BRI voice terminal (such as an ISDN 7505) that uses a SPID. In this case, the station should also be assigned using a locally defined terminal type to take full advantage of the capabilities of the PC Interface. This terminal type should also be non-initializing with no support of MIMs. nInternal Features Specific internal features available depend on the application package used. The PC/PBX Connection p roduct provides extensive local directory capability (up to 32,000 entries). They also provide a Last Number Dialed capability that is separate from the Last Numb er Dialed feature on the DEFI NI TY s yst em Generic 3. nData Mo dules Voice terminals with data mo dules are not recommended for use with the PC Interface feature (except for 3270 Data Modules when 3270 emulation is used). If a DCP data module (such as a DTDM) or ISDN data module (such as an ADM-T) is attached to the voice terminal used in conjunction with the PC Interface card (either DCP or ISDN-BRI), the d ata module will be bypassed (not used). All interface functions are performed by the interface card even if a data mo dule is present. nDisplay Modules and Terminals Display modules can be used. See ‘‘Feature History’’ for administration limitation. nCall Ap pearances The PC/PBX Connection package supports five a p pearances, one of which must b e dedicated to data use. This configuration limit may not be optimal for some users (such as attendants) who need many call appearances. The PC/PBX Platforms can support the maximum allowed by switch administration (52). The PC/ISDN Platform sup p orts many more call appearances. On the DEFINITY system Generic 3, the PC/ISDN Platform is limited by switch administration to a maximum of 208 call appearances (52 call appearances per interface card X a maximum of four interface cards = 208 a p pearances). Note that each extension number is limited to 12 appearances. This means that each interface card can accommodate four and one third extension numbers (without any bridged appearances). Special applications software must be installed on the PC to provide access to all these appearances.
PC Interface Issue 3 March 1996 3-949 n7404D Voice Terminal The 7404D voice terminal with messaging cartridge cannot be used with the PC Interface. The 7404D is manufacture discontinued and may no longer be ordered. The 7404D with PC cartrid ge is used only with Group 1. Interactions With Other Features The PC Interface feature interacts with most other features in the same way as other DCP and ISDN-BRI voice and data terminals. nData Communications Ac c ess The PC Interface feature uses a digital interface (either DCP or ISDN-BRI) and is not directly compatible with the Data Communications Access feature which uses an analog interface. Modem Pooling like conversion must be applied if these two features are to be used together. nData Protection The PC Interface feature is used for data communications, therefore Data Protection—Permanent should be assigned. nHost Computer Access Both the PC Interface feature and the Host Computer Ac c ess feature use digital interfaces. These features are directly comp atible (no Modem Pooling conversion needed). nISDN-BRI (Basic Rate Interface) The ISDN-BRI feature must be active on the switch to use the PC/ISDN Platform (Group 3). With ISDN—BRI configurations, up to four PC/ISDN interface cards can be installed in one PC. When multiple cards are used, each card is assigned to a separate and distinct interface on the switch. Separate interface cards cannot share the same ELL (Equipment Line Location). Each separate interface card can have its own separate voice terminal or voice-calling device. When a voice terminal is used, special applications software is not required on the PC. However, to use a handset or headset alone, special applications software is needed. nModem Poolin g Modem Pooling is need e d if the PC Interface feature is used to p lace calls to, or receive calls from, off-premises stations over analog trunks. Restricting Feature Use The voice and data appearances used by the PC Interface are subject to the same general restrictions as other like appearances. These can be applied either as fixed restrictions through the extension c lass of service, or as temporary restrictions through the Attendant Control of Voice Terminals feature. Other

PC/PBX Connection Issue 3 March 1996 3-955 PC/PBX Connection Feature Availability This feature is available with all current Generic 3 releases exc ept new installations. Description PC/PBX Connection is a PC application that runs on the PC/PBX platform. Refer to the se ction PC Interface in this manual for more details. This feature brings the voice terminal and PC together into an integrated voice and data workstation. The PC can be any IBM-compatible PC. AT&T provides the hardware for this connection. The hardware consists of a PC expansion card and a 7-foot modular cord. The software includes a variety of packages available from different vendors. Contact your AT&T representative for more information. For information on the UNIX PC, see the section entitled PC Interface in this manual. Security Measures There are two areas where unauthorized use may develop with this feature. The first involves unauthorized users who come to a PC and attempt to make calls from it. The software in the PC installed by the feature has a security setting. A user can place the PC in Security Mode when it is to be left unattended. Automatic Security can also be o ptioned by the administration program on the PC. With Automatic Security enabled, when the software is executed, it brings up the program in security mode. This mode is password-protected on the PC. The password should be changed often, and record s of it should be secured. The second area involves remote access to the PC over its data extension. Files stored in the PC can be deleted or copied with this feature. This can also b e password-protected, and this password should be changed frequently and protected. Consult the GBCS Product Security Handbook, 555-025-600, for a d ditional steps to secure your system and to find out about o btaining information regularly about security developments. Considerations By providing PC users with the voice and data capabilities of a fully integrated voice/data workstation, the PC/PBX Connection feature makes communications more efficient. Also, PC users with the PC/PBX Connection feature are linked for easy access to other PCs, mo dem pooling, and on- and off-site comp uters.
Feature Descriptions 3-956Issue 3 March 1996 Interactions When a station is optioned for PC/PBX on the station form, and if the set is a display set, the call display is slightly altered. The ap p earance identifier (a= , b =, c=, d=) is omitted. If the Call Log feature is enabled in the PC/PBX Connection software, the display information is captured to disk. The log can be searched. The searc h criteria b egins at the left of the displayed information. By omitting the appearance designator, a user c an enter a search string without contending with the appearance identifiers in the displayed information. Administration The PC/PBX Connection feature is administered on a per extension basis by the System Manager. A PC is assigned to the system just as any other station would be with the station typ e administered as ‘‘pc.’’ An additional field is then specified for the type of digital voice terminal to be connected to the PC. Hardware and Software Requirements A port on a TN754 Digital Line Circ uit Pack (TN413, TN754B) is required for each PC to be connected.
