Digium TE122B

Digium TE122B Digital PCI Card

The Digium TE122B is a single span, selectable T1 (24-channel), E1 (32-channel), or J1 (24-channel) card. The card utilizes Digium's VoiceBus™ technology. VoiceBus technology allows the TE122 to use an industry standard bus-mastering PCI interface, as found in millions of PCs worldwide, to maximize system compatibility and eliminate system conflicts. Improving upon the prior TE120P which does not offer expansion capabilities, the TE122 may be combined with a Digium VPMADT032 echo cancellation module to deliver 128ms of echo cancellation across 30 channels in E1 mode or 24 channels in T1 mode. Bundled with the VPMADT032, the product SKU is TE122B.

Digium TE122B Digital PCI Card Overview

The Digium TE122B supports both voice and data modes on its single span. For example, the card can support 12 channels dedicated to voice, routed directly to the Asterisk Open Source PBX, and 12 to data, handled by the underlying Linux operating system, thus eliminating the need for an external router. The TE122 works in both 3.3V and 5V PCI slots by auto detecting the slot's voltage.
