Even supposing i've got a print replica of the ebook, I commute much so I placed all my "working reference books" on my kindle, so i don't need to hold loads of books ( WCF and Biztalk quite often ), So Amazon and writer, please post this e-book for kindle. .. .

Scr 78 39 The Underlying Causes There are Three Fundamental Causes of Imperfect Modem Connections, the First Two Causes are Just Corollaries of Each other: • Poor circuit quality (relative to the desired modulation/speed) • Excessive modulation/speed (relative to the circuit quality) 210 1081_06F9_c2 © 1999, Cisco Systems, Inc. ) The Third Underlying Impediment to Perfect Modem Connections is What One Can Call Modem Quality. Quality There are Several Aspects to Modem Quality: • The ability of the modem optimally to resolve the data from the analog signal received • The ability of the modem to select the optimal receive modulation/speed for the given circuit • The ability of the modem to interoperate nicely with the vast and evershifting range of peer modems (of various quality) encountered in the field 210 1081_06F9_c2 © 1999, Cisco Systems, Inc.
