I wonder if I'm getting induction on my isdn line ? The Tengleman shop under me shares same cellar & cable runs I believe, & my log shows this: isdnd.log:05.01.2002 13:50:43 CHD 00199 Call from NotAvailable to 23269369 isdnd.log:05.01.2002 13:50:47 CHD 00200 Call from NotAvailable to 23269369 isdnd.log:08.01.2002 15:57:30 CHD 00218 Call from "TW Tengelmann" to 23269369 isdnd.log:08.01.2002 15:57:34 CHD 00219 Call from "TW Tengelmann" to 23269369 isdnd.log:08.01.2002 15:57:54 CHD 00220 Call from "TW Tengelmann" to 23269369 isdnd.log:08.01.2002 15:57:58 CHD 00221 Call from "TW Tengelmann" to 23269369 I had a word with the manageress of Tengelmann just after the last event, & she said yes she or someone had been phoning from 26022660 (which is aliased to TW Tengelmann in my alias file). +49.89.23269369 answerphone announces as "something & Thomas Lange" She said she knows that number too ! We are both puzzled ! I'm intrigued, All I can think of is : - line induction from paralle cables - I've registered for DSL, maybe D.Telekom have changed my line impedance at the exchange end (& as I live in middle of city, it'll be a short cable, so inpedance my end will have changed too. ( I got an envelope today with T-Online software (that I presume & hope will be fully irrelevant under Unix) so they're getting ready to switch my line I guess, though I haven't received a splitter yet.) I've also wondered what the security is on ISDN lines. On analogue, people sometimes break into cellars, put an active switcher on cable, & make calls at neighbours expense for years before if ever anyone has a clue, What's the feasability for ISDN ? & DSL ? How safe are we ? OK, I dont expect Tengelman (a big food chain in Germany) is up to tricks, but there's something strange happening & it reminds me about those cables in the common cellar area of this big building.
