It will be opened via their <strong>Adastral Park<\/strong> building in Ipswich (Suffolk, England) and is expected to be available from <strong>20th August 2013<\/strong>. <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/go\/britishtelecom\" rel=\"nofollow\" target=\"_blank\">BT<\/a> has traditionally used this facility for its own internal testing and some PR.<\/p>\n<blockquote class=\"bq1\"><p><strong><a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/openreach\" target=\"_blank\">Openreach<\/a> Statement &#8211; NGA Test Facility<\/strong><\/p>\n<p>&#8220;<em>A room within the facility may be booked out by a CP for a short period of time during each network testing window so that they can run their own tests and checks before changes roll out to the live network.<\/em><\/p>\n<p><em>CPs must have first gone through a product establishment procedure on one of the NGA products before using the facility since access line orders are placed using our Equivalence Management Platform (EMP).

ISPs will have to provide a <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/vdsl\">VDSL2<\/a> filter that plugs into the Metallic Line NTE (i.e. to separate the PSTN\/phone and <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/vdsl\">VDSL2<\/a>\/broadband signals on the same line) and a modem device which plugs into the filter.<\/p>\n<p>However it should be noted that the downside of this approach is that \u201c<em>the use of microfilters may result in reduced speeds when compared to an engineer-based installation<\/em>\u201c (Openreach), which partly occurs because the engineer is no longer present (i.e. some of the work they do helps to reduce interference). Some fear that the speed detriment could be significant but we&#8217;ll have to wait for the imminent <strong>summer 2013 trial<\/strong> to see (note: engineer installs should still be an option).<\/p>\n<p>The new SIN document notes that two possible connection topologies exist for these filters, which we&#8217;ve pasted below. Take note that these are intended for the more telecoms minded among you.<\/p>\n<blockquote class=\"bq1\"><p><strong>2.4.2 Filter Installation topology<\/strong><\/p>\n<p><em>In the cases outlined in Figure 8 and Figure 9, the filters are classed as Customer Premises Equipment (CPE) and could be deployed in two distinct topologies. Either multiple jack-connected CPE filters can be used as in the arrangement shown in Figure 8, or a single centralised in-line filter can be provided as in the arrangement shown in Figure 9. In all cases, there must be a filter function between the line-box and any item of PSTN CPE, including modems, fax machines, set-top boxes etc.<\/em><\/p>\n<p><em>When CPE <a href=\"https:\/\/www.ispreview.co.uk\/index.php\/link\/vdsl\">VDSL2<\/a> filters are used, the network termination point (NTP) for VDSL2 services to which this SIN relates, is located at the Line-box. However the physical VDSL2 modem may be connected into one of the VDSL2 CPE filters as shown in Figure 8, or into a centralised filter as shown in Figure 9.<\/em><\/p>\n<p><em>Note that when a centralised CPE VDSL2 filter is in use as shown in Figure 9, the VDSL2 modem can ONLY be connected at the line-box, as the filter prevents the VDSL2 signal reaching the extension sockets.<\/em><\/p><\/blockquote>\n<p>Now the diagrams..<\/p>\n<div align=\"center\"><img decoding=\"async\" class=\"ngg-singlepic ngg-none\" alt=\"fttc self install filter topologies\" src=\"http:\/\/www.ispreview.co.uk\/wp-content\/gallery\/2013-article-illustrations\/fttc_self_install_filter_topology.png\" \/><\/div>\n","protected":false},"excerpt":{"rendered":"<p>BTOpenreach has launched a new Next Generation Access (NGA) test facility to help UK ISPs conduct live network tests of new broadband services and devices before making them available.
