Initiatives

• Operational Guide– Open item regarding Scope

The TIA Engineering Manual requires elections of Formulating Group Chair’s and Vice-chairs. These elections provide a method of having peers choose their leadership. However, when leadership changes, it can cause difficulty in understanding the needs of the committee and TIA process. This guide is offered to enhance the smooth transition of leadership and provide a structure to the Engineering Committee.

The TIA Engineering Manual and its Advisory Notes, along with the TIA Style Guide take precedence over this guide.

Initiatives

• TAG meetings being held in conjunction with TR-42 meetings– US TAG to TC86, SC86A, SC86B and SC86C

• These TAGs are becoming more “correspondence only”

– US TAG to ISO/IEC JTC1 SC25 WG3• These meetings began this year and are found to be beneficial towards

harmonization

6

Initiatives• Loss Budget Task Group (TR-42.11)• Encircled Flux Round Robin (TR-42.11)

– TSB is being worked on• Bend insensitive multimode fiber

– Being worked in TR-42.11 and TR-42.12– Attempting to ensure encircled flux compliance

• Task Group is pursuing the next edition of premises standards in TR-42 (e.g., 568-D Series)

• Next generation balanced twisted-pair cabling Task Groups have identified objectives– Developed Editor's draft 0.2 of PN-568-C.2-1 (to be

published as ANSI/TIA-568-C.2-1, "Specifications for 100Ω Next Generation Cabling”) to work with 40GBASE-T

7

Initiatives• Educational Facilities

– Draft under review by Subcommittee• Large facilities (e.g., stadiums, airports)

– Task Group established beginning investigations• Ensuring security of cabling (physical)

– Task Group draft established– Includes Electronics, cabling, physical damage, terrorism,

industrial sabotage, data security for wired and wireless• Fabric architecture for data centers

– Document out for ballot• STEP will be proposing a new Subcommittee within TR-42

at June meeting

8

Initiatives• M2M will be monitored (joining TR-50)• Telecommunications Cabling Guidelines for Wireless

Access Points– Written in 2006 and will be revised to include current and

future wireless access points (e.g., 802.11ac)• Distributed antenna systems (DAS)

– Currently included in educational facilities document• Energy Management Systems

– Will be discussed in TR-42.1 to determine whether an addendum to TIA-862-A is favorable.

• Addendum to TIA-607-B, Bonding and Grounding– Grounding electrodes and their testing

9

Initiatives• Began working with BICSI Standards to coordinate efforts

on standards development– TIA developing requirements– BICSI developing “best practices”

10

Issues being worked on by TIA

• Document management (processing)– What documents are due for committee action?

• Hundreds of documents are the responsibility of TR-42 and its Subcommittees• System is needed to alert Subcommittees or Engineering Committee of pending

action (notification after 3-year mark and 5-year mark)

– Assigning ballot numbers• Keep the list current on TIA WEB site• Allow automated ballot numbers for new projects

– What is the status of a publication?• Is the document in TIA? ANSI? Projected publication date?

• Voting member status– Expand to have primary and alternate

• Allow as a choice of each company• Useful for operational efficiency of member company

11

Issues being worked on by TIA

• Document searches (numbering)– Difficult to search

• Need specifics to search (TIA-, TIA/EIA-, EIA/TIA-, EIA-)• Some documents have additional punctuation (TIA/EIA-492.AAAC)

– Better (more forgiving) search engine may be needed• Resolving issues will likely free-up Standards Secretariat’s

time, ease work-flow in Subcommittees, allow timely updates to standards documents

Training session after February Opening Plenary; will likely continue at each meeting

12

Standards being published

• ANSI/TIA-568-C.0-2, Generic cabling• ANSI/TIA-942-A, Data Centers• ANSI/TIA-570-C, Residential• ANSI/TIA-606-B, Administration• ANSI/TIA-1183, Test fixtures for balunless network

analyzer measurements

• Some glitches had been fixed by TIA to further the process of publication
