Chapter 5 - Special Applications 63The DBS 576 is designed to accommodate a wide variety of features as described throughout thisdocument. However, this powerful phone system is also designed to support fast-emergingtechnological trends and specialized 3rd-party product integrations. Listed below are some examples.) Companies with two or more offices can benefit from the DBS 576’s powerful networking features byestablishing private phone connections between the sites. Typically, companies with multiple siteshave a high level of call traffic between them, resulting in astronomical phone bills if they’re using thepublic switching network (COs). In a private network, however, the company pays a fixed rental fee forthe private lines, regardless of how often they are used. In fact, the more they’re used, the moremoney the company saves. A private network also provides other benefits, such as increasedefficiency by allowing the user to dial an extension number instead of a long-distance number.The DBS 576 can provide networking features such as:Network Call Transfers. Allows a call at an extension to be transferred to an extension inanother network PBX.Network Extension Calling. Allows you to reach an extension on another DBS 576. Based onthe number you dial, the DBS 576 network routes the call automatically.Network Paging. Allows users on one DBS 576 system to page on another DBS 576, when theappropriate Class of Service allows.Network Call Routing (“Closed Numbering”). Allows multiple systems that are interconnectedin a network, to direct calls to a specific tie line based on the number dialed (the call does notleave the network). This allows intercom calls to be conducted between locations that wouldnormally be considered long-distance calling.Tandem Connection. Allows calls over network tie lines to be automatically routed to anotherPBX, out to the public network, or to internal extensions. The tandem relay function increasesnetwork efficiency via automatic routing methods between multiple PBXs, thus reducing thenumber of tie lines needed.Centralized Attendant. Via tie-line routing, operator calls and associated operator functions(paging, transfer, reversion for unanswered calls) are performed from one Attendant position inthe network.Centralized Voice Mail. One voice mail system, installed in one of the network PBXs, serves allextensions in the network. The functions needed for voice mail operation (Call Forwarding to theuser’s mailbox, Priority Message-Waiting to indicate the mailbox message on the user’s phone,and MSG ID Notification for accessing the mailbox and retrieving messages) are simplyprogrammed to be routed over the tie lines.These powerful networking functions are facilitated by the following DBS 576 hardware connections:E&M Tie Lines. Multiple DBS 576 sites can be connected over leased voice lines.T-1 Interface. Multiple sites (called “nodes”) can be tied together through network trunk lines, sothat (for example) when one site closes for the day, another node across the country can pick uptheir calls. Network users can also turn a long-distance call into a local one, by accessinganother (long-distance) node and then dialing the (local) number.!" -
