-
- I promised a review of the Motorola "Blue Book" or "Cellular Subscriber
- Technical Training Manual." This book is the companion material for a
- two day course required of technicians in an authorized Motorola cellu-
- lar service shop.
-
- After a discussion of installations safety, the book opens with a
- Cellular Overview in which AMPS and NAMPS are explained in 23 pages.
- In block diagrams, flowcharts and text, the processes for going on the
- air, making calls, receiving calls and processing handoffs are
- presented. Band plans and channel layouts are also described.
-
- Next, Section 2 presents a detailed look at the Motorola line of
- cellular phones, both past and present. Model identification is
- presented, as is a look at the accessory lines for the telephones.
-
- Section 3 is probably the section in which most readers of this review
- have interest. Section 3 presents programming information for
- virtually every field programmable Motorola telephone including the
- 8000 series, 9000 series (Ultra Classic) and all forms of Micro-TAC
- Flip-Phones.
-
- Programming via the "security code method" is taught, and also entry
- into "Test Mode" and the steps for programming the phone this way.
- The implication here is that the holder of a Blue Book, who is
- manually dexterous enough, and has sufficient ingenuity, to get the
- phone into test mode, can get past the security and lock codes to
- program mode, read and change those codes.
-
- Another interesting feature explained in Section 3 is the Test Mode
- display. The test mode display, when first started, displays the
- cell's control channel number and signal strength (RSSI) are
- displayed. This alternates with (or on large displays is displayed
- with) a set of seven status bits for the phone's settings. If you are
- interested in knowing where the cells are and which cells are used in
- what locations, ride around in test mode for a while. Note that Test
- Mode will drain a portable's batteries in a few hours since the lamp
- and display never go out, and any power saving features of the
- Microprocessor are not enabled. Use a power adapter in the car, or
- carry extra batteries.
-
- Section 4 discusses installation of mobile telephones in vehicles.
-
- Section 5, Troubleshooting and Repair, is another gold-mine for the
- interested end user. While you won't want to open or adjust your
- phone, an understanding of the various signalling methods can be
- obtained by reading the tuneup procedures. At the end of this section
- is a complete list of Test Mode commands, which includes such things
- as opening the receiver on any channel, putting the transmitter on the
- air manually (a violation of many FCC regulations for the end user,
- I'm sure) and completely resetting the phone. Such a reset will clear
- the call counters (including the cumulative counter, I believe) and
- also the three (or fifteen) time programming counter.
-
- Section 6 descibes procedures for moving ESNs from one phone to
- another when loaners and spares are issued. There is a lot here that
- is _not_ said, but it seems that special loaner and spare phones are
- issued to shops that can receive the ESN of another similar phone.
- Note that the original phone is rendered useless until returned to the
- factory, so this is NOT a procedure that allows two phones to share
- one ESN, which would not be a proper setup according to the cellular
- carriers.
-
- Finally, Section 7 concerns requirements for service shops and warrantee
- exchange programs.
-
- The book concludes with five appendices and an index. The appendices
- are:
-
- Corrective Service Bulletin Index
- Tools and Parts
- Glossary of Terms
- Cellular Frequencies
- Warrantee Requirements
-
- The question arises whether a person should order this book. If you
- want to understand how cellular systems work, a good technical
- bookshop may be a better bet. If you have a burning desire to be able
- to active all the modes of your phone even if they are useless, then
- you are like me and will want this information. If you want to drive
- around tracking cell sites, you'll enjoy test mode, but I strongly
- recommend using a mobile telephone rather than a portable for about
- five good reasons.
-
- Ordering Info: Call Cellular Subscriber Service at 1-800-331-6456 (US
- Only) or fax to 708-523-3402. Asia-Pacific customers may fax to +1
- 708 523-8060. Order part number 688A60 (Training and Orientation
- Manual). The price is $30.00 and there was $5 shipping added for UPS
- Ground. Motorola also charged me sales tax, and the total was $37.48.
-
- Enjoy.
-
- PS: Another neat thing to ask for is the Cellular Accessory Catalog,
- which is free.
