DIGIUM TDM2400P - BLANK BOARD AND MODULES IN BARKLY WEST

Using Digium's Asterisk Open Source PBX software and standard PC hardware, one can create a telephony environment that includes all the sophisticated features of a high-end business telephone system. Using an industry-standard bursting, bus-mastering PCI interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus™ technology, the TDM2400P eliminates the requirement for separate channel bank and T1 interface cards, at an industry-leading price. The quad-FXO and quad-FXS modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior echo cancellation on both FXO and FXS interfaces. Scaling of this solution is accomplished by adding additional TDM2400P cards. 24 Port Analog Features: Up to 24 Ports through a combination of FXS and FXO modules Full-length Analog Card Up to 6 Quad FXS or FXO Modules RJ21X Connector High Performance Echo Cancellation (HPEC) Software (Optional) VoiceBus™ technology TDM2400 for use with a PCI 2.2 compliant slot - Bundled with VPMADT032 as TDM2400E AEX2400 for use with a PCI-express 1.0 compliant slot - Bundled with VPMADT032 as AEX2400E Digium VPMOCT032 Module For Asterisk users who connect to the PSTN, the most common type of echo is hybrid echo - the echo introduced by the impedance mismatch between 2-wire and 4-wire telephone circuits. The echo manifests as a distorted and delayed reflection of the users voice while in conversation with an external party through the PSTN. Asterisk itself offers a range of software-based open source echo cancellation routines that are moderately effective in eliminating the hybrid mismatch echo that most Asterisk users experience. However, there are cases in which these algorithms are not effective. To combat this, Digium introduced DSP-based echo cancellation modules for our multi-port T1/E1/J1 cards and our 24-port analog card. Now, Digium is pleased to make available the VPMOCT032 echo cancellation module. This module, which offers 128ms (1024 taps) of echo cancellation across all of its channels and provides the same toll-quality G.168 compliant echo cancellation found in Digium's HPEC software-based commercial echo canceller. The VPMOCT032 is immune from any system CPU spikes that might otherwise affect a software-based solution.
