Digitally modulated radio-frequency (RF) signals manifest unique characteristics at personal communications (PCS) frequencies when they are reflected. Reflections add out-of-phase data symbols that cause bit errors. Paradoxically, simple signal-strength measurements at PCS frequencies (using signals with a narrow bandwidth, such as a continuous wave [CW]) can be deceptive because, although the ...

Muxponders offer service providers a more efficient use of wavelengths on CWDM and DWDM systems. Muxponders multiplex lower rate signals into a higher line rate. For example, a muxponder would multiplex four OC-48 client rates into an OC-192 line rate or eight GbE client rates into a 10 Gb/s line rate. This would provide a 4:1 or 8:1 efficiency gain in fiber or wavelength utilization in the ...

Voice over IP (VoIP) will become the dominant means of transmitting telephony conversations in the coming years. This move from traditional circuit-switched to packet-switched technology will have a significant impact on the systems used to record communications.
This white paper discusses and explains recording of Voice over IP (VoIP) telephony traffic. How can a company deploy VoIP ...

This document pertains to high end Asterisk-based IP-PBX telephony configurations. The load test results, which reflect months of optimization efforts and repeated testing, provide factual evidence of the capacity of different configurations of the IP-PBX to handle telephony traffic with various codecs and echo cancellation tail sizes. In a recent Webinar, which was recorded and is available for ...

The solutions you choose for media ingest and encoding (taking live or tape-based video and audio sources and converting them into compressed file formats for distribution), transcoding (converting existing media files into new file and compression formats) and streaming (taking live video and audio sources, encoding them, and distributing them as live streams) do not monetize content in and of ...
