Data Management Solutions

■Default Dialing enhances computer dialing by allowing a computer user to place a data call to a pre-administered destination by simply entering a carriage return at the “DIAL:” prompt. This gives computer users who dial a specific number the majority of the time a very simple method of dialing that number.

■Data Call Setup enables you to set up data calls (at any of the industry-standard rates) using a telephone or a computer keyboard.

■Data Hotline enables you to administer a data module so that when the module goes off-hook the data call is immediately placed to the preassigned number. This feature may also be used to restrict a data module to the assigned number only.

■Data Protection prevents disruption of data transmissions by DEFINITY ECS’s other features or tones. Both the originating and terminating ends of the call are protected.

■Data Communications Access allows you to communicate with a computer via analog trunks.

■Host-Computer Access allows data endpoints with data modules to access a computer directly.

■Modem Pooling allows conversion resources to be grouped into pools and shared for access to analog facilities, eliminating the need for a dedicated modem at every terminal.

Digital Interfaces

Lucent Technologies DEFINITY ECS offers powerful digital interfaces for high-speed voice, data, and integrated voice/data transmission.

■Lucent Technologies Digital Communications Protocol, a key part of DEFINITY’s digital architecture, provides integrated voice and data communications between terminals and the system.

■Lucent Technologies Digital Multiplexed Interface is a high-speed, economical interface for terminal-to-host, switch-to-host, and host-to-host communications.

DEFINITY ECS supports a wide variety of bit-oriented signalling formats on Digi- tal Signal Level 1 (1.544-Mbps) facilities, compatible with local CO services, AT&T nodal network services (such as AT&T MEGACOM services), and services conforming to European Conference of Postal and Telecommunications stan- dards in the international marketplace (2.048-Mbps).

DEFINITY ECS implements both standard ISDN interfaces: ISDN-PRI and ISDN-BRI. It is one of the first systems to make both ISDN interfaces available at all line sizes — small, medium, or large. With both interfaces, Lucent Technolo- gies delivers the advantages of full end-to-end ISDN connectivity to every desk- top.
