Fax Applications

Introduction

The DSP Series 2 card supports a suite of intelligent fax capabilities that are compliant with the ITU T.30 fax protocol, recognized worldwide. You can use the T.30 Fax suite to develop applications that transmit and receive Group 3 facsimiles concurrently on all channels, at rates up to 14,400 bps.

Fax Messaging Applications

Supported Fax Applications include:

• LAN Fax

• Fax Broadcast

• Fax-on-demand

• Fax Messaging

Fax Server Products

Fax server products can be key components of large-scale, media server-based fax applications for the enterprise (for example, fax servers) and for large-scale Fax Service Provider systems. Dedicated fax servers serve more users while reducing hardware cost. Fax servers let companies distribute information to large audiences for pennies a page, and to eliminate bottlenecks associated with the limited capacities of traditional fax machines.

T.38 Support

The T.30 Fax suite can also be used to produce fax server products for IP telephony gateways when used with T.38. You must use the IP Signaling Series 3 card for T.38. The DSP Series 2 card does not itself support or terminate T.38.

Store and Forward

A host application running on the CSP with the T.30 Fax suite can use ITU T.37 fax store and forward. Although the T.30 Fax suite does not explicitly support ITU T.37 fax store and forward, the suite does support the T.37 page format, which is specified as 1D encoding, LOW resolution, and A4 page width.
