"Notes on the Network" was replaced with "Notes on the BOC Intra-LATA Networks - 19nn" where "nn" indicates the year released. The latest edition I have is 1986. There could well be a more recent release. The '86 edition does not give information on ordering "Notes" itself. The following address was listed for "Technical Advisories": Bell Communications Research Information Exchange Management 435 South Street, MRE 2J-155 Morristown, NJ 07960-1961 The '86 edition is Technical Reference TR-NPL-000275. The price is not stated, and I don't remember what it was ... but expect well over $100. The book is indispensable if you live in the telecom industry. Floyd L.
