Series 6 Model 70 PDF Print E-mail

An entry-level system designed for smaller sites, the Model 70 offers the same features and functions as higher capacity Series 6 models, but in a smaller, cost-effective package.

Because Centigram employed a single user interface and the same operating system for all Series 6 models, the Model 70 is ideal for small businesses and multi-site enterprises that want to network large and small systems at multiple sites. Since all Series 6 models incorporate the same high-density analog and digital port connectivity, the Model 70 provides the same speed and power formerly available only on larger Centigram systems.

And to meet the needs of small but growing businesses, the Model 70 allows customers to migrate easily to the larger Model 120R/S and the Model 640.


The Model 70 provides a powerful, feature-rich solution for today's leaner businesses. And by incorporating computer telephony integration (CTI) and digital signal processing (DSP) technology today, the Model 70 allows customers to implement advanced applications such as text-to-speech and voice recognition tomorrow.  In addition, the Model 70 supports all the same applications and features as higher-capacity Series 6 models, including:

  • VoiceMemo ®, a feature-rich voice messaging product.
  • FaxMemo, a mailbox-based fax management product.
  • OneView™, an integrated multimedia messaging product for the desktop.
  • CallAgent ®, an advanced call processing solution for individuals and organizations
  • MESA-Net, a digital networking option that can link up to 1,500 Centigram servers
  • Digital integration with virtually any PBX or Central Office or telephone system
  • Computer Telephony Integration (CTI) and Digital Signal Processing (DSP) technology for future application support.


Included as a standard feature, the Model 70 uses integrated drive electronics (IDE) technology to integrate controller functions into the disk assembly, making an interface card unnecessary. Hard Drive redundancy ensures that no system data is lost - even if one of the drives is removed from service. A primary drive and its redundant partner function as "mirror images" of each other; when a drive is put back into service, it automatically synchronizes itself with its "partner." As a result hard drive redundancy enhances system availability.
