Lucent Technologies 555-230-024 manual Series Data Modules

Data Management Solutions

There is an interface that can be configured as an RS-366 Automatic Calling Unit or an RS-232 asynchronous data interface that supports a limited AT command set for call control.

All options are software definable and stored in nonvolatile memory. The reset options feature makes it easy to load default options. Designed to be easily upgraded, the High Speed Link has a memory cartridge interface for firmer upgrades to support new features.

The unit is externally powered, and it can be rack mounted with up to eight units and located up to 5000 feet (1525 m) from the DEFINITY ECS.

7000-Series Data Modules

The 7000-series data modules are designed to give you simultaneous voice and data access in a single, low-cost data module. The single DCP connection means you will never miss a voice call when you are on a data call.

The 7400B Plus and 7400A dual-function data modules provide full-duplex, asyn- chronous connectivity for DCP applications. They emulate the industry-standard Hayes modems and work with host-connection software packages that use the Hayes command set. Priced competitively with Hayes-compatible modems (that operate at 1200-2400 bps), the modules give you a choice of transmission speeds ranging from 300 bps to 19.2 kbps.

The 7400B Plus provides integrated, simultaneous, voice/data communications over twisted pair wiring. It is easy to install and operate and plugs into any modu- lar DCP telephone outlet. It features two ports: a modular DCP port for a digital telephone and an RS-232 port for a personal computer or terminal.

In desktop configuration, the 7400B Plus provides twisted-pair connectivity for personal computers and asynchronous computers at transmission speeds rang- ing from 300 bps to 19.2 kbps. It operates with all 7400-series digital telephones, including the CallMaster Voice Terminal. On the trunk side, the 7400B Plus can connect to asynchronous host computers at speeds as high as 19.2 kbps.

The 7400A simplifies modem-pooling connections. It offers an alternative to the modular trunk data module in environments where only asynchronous communi- cations capabilities are required. When used with the 7400B Plus on the desktop, the 7400A in the modem pool can raise system speeds while supporting Hayes-compatible communications packages. The 7400A features simple con- nections: one for a DCP line to the DEFINITY ECS, another for an RS-232 connec- tion to Hayes-compatible modems.

The 7500B data module gives you synchronous or asynchronous connectivity for ISDN-Basic Rate Interface applications such as video conferencing, FAX, and personal computers at speeds up to 64 kbps. The 7500B features three connec- tions: one to the Basic Rate Interface line to the DEFINITY ECS, one to a

7500-series telephone, and one (RS-232) to the computer. The module may be used stand-alone or in conjunction with a 7500 series telephone.
