ZBTSI (zero-byte time slot interchange) - permalink - collapse

All > Technology > Telecommunications

A technique applied to a DS1 frame to ensure pulse density requirements are met, where bits 2 through 193 of each frame are scrambled to minimize the occurrence of all-zero octets. When an all-zero octet is contiguous to another octet with zeros and they would combine to violate the ones density requirement, an algorithm is invoked where some all-zero octets are replaced by an address chain. The reverse algorithms are performed by the receiving terminal.

Zeal - Volunteer Built Web Directory - permalink - collapse

All > Technology > Search > SEO / Search Marketing

First launched in 1999, Zeal was a volunteer-built web directory which was bought by LookSmart for $20 million in October 2000. Combining the work from LooksmartÂs paid editors with that of volunteers, they wrote profiles of websites and submitted them in relevant subcategories of the Zeal database. The directory content was downloaded and used by Looksmart and its partners including MSN, Lycos and Altavista. To become a Zeal volunteer, one needed to pass an introductory level test prior to submitting website profiles and being able to edit other peopleÂs work. As one gained more experience and kudos, an editor was able to create and maintain special categories of interests. The more experienced editors called Zealots and Expert Zealots were responsible for developing community and assist those people called "Community Members". Zeal had volunteer members from all over the world including USA, United Kingdom, Australia, India, Spain, Switzerland, Japan and New Zealand. When MSN pulled from the relationship, ZealÂs traffic had declined considerably which lead to its closure on 28th March 2006.

zero-bit insertion - permalink - collapse

All > Technology > Telecommunications

: A bit-stuffing technique used with bit-oriented protocols to ensure that six consecutive "1" bits never appear between the two flags that define the beginning and the ending of a transmission frame. Note: When five consecutive "1" bits occur in any part of the frame other than the beginning and ending flag, the sending station inserts an extra "0" bit. When the receiving station detects five "1" bits followed by a "0" bit, it removes the extra "0" bit, thereby restoring the bit stream to its original value. Synonyms zero insertion, zero stuffing.
