&nbsp;I had to repunch it down to another split block. &nbsp;&#x1f625;<br \/>\nPac Bell did the installation of the key system in a bldg complex in Centennial Park. &nbsp;I took over the support in 1990. &nbsp;I found that a whole bunch of 100 pair underground cable was not being used, and the unused part was always on the right side of the blocks. &nbsp;But I could get dial tone on them. &nbsp;Short story is the 66 blocks they installed on the far end were not split, so the lines were going from the MPOE to the far end on pairs 1 thru 25, and going thru the unsplit blocks and back to the MPOE on pairs 51 thru 75! &nbsp;So half the 100 pair couldn&#8217;t be used because someone screwed up and used the unsplit blocks!&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From FB group Bell Telephone&nbsp; Yeah, that&#8217;s the problem. &nbsp;Them fans whining all the time, and having to rinse out the filters in the bathroom every 6 months to keep the PBXs from overheating. &nbsp;I had to get the a\/c guys to come to the phone room often and blow out the mold clogging the<a href=\"https:\/\/rustybolt.info\/wordpress\/?p=12478\"> <\/p>\n<p> (Read More&#8230;)<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-12478","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/12478","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=12478"}],"version-history":[{"count":3,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/12478\/revisions"}],"predecessor-version":[{"id":12481,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=\/wp\/v2\/posts\/12478\/revisions\/12481"}],"wp:attachment":[{"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=12478"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=12478"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rustybolt.info\/wordpress\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=12478"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
