Digium VPMADT032 - Thirty-two (32) Channel Hardware Echo Cancellation Module
The VPMADT032 echo compensation module works with Digium IP telephony cards and provides latency reduction on configured tails up to 128 ms (1024 hours) simultaneously for all board ports. For all IP-PBX Asterisk servers connected to telephone networks (PSTN) via analog lines, the main problem was the “hybrid network” - an echo that arises due to the difference in importance in two-wire and four-wire telephone lanyards. It appears that the voice of the IP-PBX Asterisk subscriber appears blurred and blurred during the hour of communication with TFZK subscribers.
The module, which appears to be a replacement for the outdated VPM100M echo compensation module, can produce tail processing in less than 32 ms. VPMADT032 is fully compliant with the G.168 specification and is based on the Digium HPEC program. VPMADT032 is independent of the productivity and importance of the central processor of the system, in addition to software solutions.
The VPMADT032 can be used with 8- and 24-port analog Digium boards, TDM800P and TDM2400P kits and will be compatible with Digium boards in the future.
