Siemon's Valerie Maguire Reappointed for Fifth Time to TIA TR-42.7


Valerie Maguire, global sales engineer, for infrastructure experts Siemon, has been elected for a fifth consecutive term on the Telecommunications Industry Association (TIA) TR-42.7 Copper Cabling Systems Subcommittee. Maguire takes the post of vice chair on the committee, which develops key standards for copper cabling systems.

Maguire previously served the maximum two terms as chair of the subcommittee as well as holding the vice chair position for two terms, beginning in 2001. She has actively participated in TIA standards formulation since 1995 and currently serves as document editor for multiple TIA standards.

TIA TR-42.7 develops standards for balanced twisted-pair cabling systems and is the formulating group that authored the ANSI/ TIA-568-B.2-10 (category 6A) and, recently published, ANSI/TIA-568-C.2 standards. The subcommittee specifies twisted-pair connecting hardware, patch cord, and cable requirements, including test procedures, performance limits, and test instrument parameters.

Within the TIA, more than 1,000 individuals, with representatives from manufacturers, service providers and end users, including the government, serve on the formulating groups involved in standards setting.

Valerie Maguire's expertise is focused in the fields of balanced twisted-pair and fibre optic telecommunications cabling, connecting hardware, and cables. She has authored over 45 technical articles and engineering papers, holds one patent and in 2008 received the Harry J Pfister Award for Excellent in Telecommunications. In addition to her post on TR-42.7, Maguire also serves as liaison to IEEE 802.3 on TIA TR-42.

Commenting on her re-election Valerie Maguire said, "Working to develop future standards is the most interesting and exciting aspect of my professional life; I thoroughly enjoy the technical process and the opportunity to share insight with other professionals from across the cabling industry".

Many of Valerie Maguire's papers are available for free download from the Siemon website. These include the ebook '10 Gigabit Network Cabling', the white paper 'Demystifying Cabling Standards' and guides on specific topics such as running video over structured cabling. Search the library at
