- DEFINITIONS
- -----------
-
- NOTE: Most manufacturers use a "1" to enable and a "0" to disable options,
- there are some exceptions and these are noted within the specific
- phone's file.
-
-
- ACCOLC ACCESS OVERLOAD CLASS
-
- A two digit field used by the Cellular carriers to determine who has
- priority access in the event of an emergency. This has not been widely
- implemented and the suggested entry is 0 and the last digit of the
- telephone number for general subscribers.
-
-
- EE END TO END
-
- A single digit (1 bit) entry that determines whether DTMF tones ("Touch
- Tones") are transmitted over the voice channel to allow access to remote
- services. Set to "1" under normal circumstances.
-
-
- GIM GROUP IDENTIFICATION
-
- A two digit/four bit field that determines how much of the SIDH is used to
- identify when the mobile is roaming. This number is normally 10 in the USA.
-
-
- HA HORN ALERT
-
- A single digit (1 bit) entry that enables the horn alert on mobile phones.
- When enabled ("1") most mobiles will send a ground pulse to the horn alert
- connector (usually a wire in the power cable) during the first few rings.
- This is designed to honk the horn or flash the lights, a relay must be
- used to avoid damage to the phone as the output pulse is low current.
-
-
- HF HANDS FREE
-
- A single digit (1 bit) entry that enables the hands free feature on phones
- so equipped.
-
-
- IPCH INITIAL PAGING CHANNEL
-
- A three digit number indicating the initial paging channel, normally set
- to 333 for non-wireline (A) and 334 for wireline (B) systems. A leading
- zero is common in this field.
-
-
- LU LOCAL USE MARK
-
- A single digit (1 bit) field that determines whether the phone transmits
- registration information as soon as it powers up, usually set to "1".
-
-
- MIN MOBILE IDENTIFICATION NUMBER
-
- This is in fact two entries, MIN1 and MIN2. MIN2 is the three digit area
- code and MIN1 is the seven digit phone number. On most newer phones this is
- entered as one ten digit number and is rarely referred to as MIN1 and MIN2.
-
-
- MM MIN MARK
-
- A single digit (1 bit) entry that determines whether the phone transmits the
- area code when accessing the system, usually set to "1".
-
-
- PS PREFERRED SYSTEM
-
- A single digit (1 bit) entry that determines whether the mobile scans
- channels 1 through 333 for the "A" system, or channels 334 through 666 for
- the "B" system. Set to "0" for A, and "1" for B system. This entry should
- match the last digit of the SIDH (see below).
-
-
- REP REPERTORY
-
- A single digit (1 bit) entry that enables repertory memory (speed dialing),
- normally set to "1".
-
-
- RM RADIO MUTE
-
- A single digit (1 bit) entry that enables the radio mute feature on mobiles
- so equipped. Generally only available when the horn alert feature is
- disabled as the radio mute often uses the same wire as the horn alert.
- When enabled the radio mute wire/connector will go to ground when the phone
- is in use. Use this ground to turn off or mute the car stereo, as with horn
- alert use a relay.
-
-
- SCM STATION CLASS MARK
-
- A 4 bit binary, 2 digit decimal field that designates the power output,
- number of channels and whether the phone is capable of VOX operation (voice
- operated, or push to talk transmission. Saves battery life on portables,
- only relevant when the Cellular system supports this feature). The most
- common entries for this field are:
-
- BINARY DECIMAL # OF CHANNELS POWER OUTPUT VOX
-
- 0000 00 666 3 NO
- 0010 02 666 .6 NO
- 0100 04 666 3 YES
- 0110 06 666 .6 YES
- * 1000 08 832 3 NO
- ** 1010 10 832 .6 NO
- 1100 12 832 3 YES
- 1110 14 832 .6 YES
-
- * Most common for all newer mobile phones.
- ** Most common for all newer portable phones.
-
-
- SIDH SYSTEM IDENTIFICATION (for) HOME SYSTEM
-
- A five digit decimal number that is specified by the system operator. The
- last digit corresponds to the Preferred System mark 0 or 1 (see above).

-
- PART II. DEFINITIONS
-
-
- The following is a list of commonly used abbreviations used in cellular
- phones.
-
- SIDH
-
- A 15-bit field in the NAM designating the System Identification for the Home
- System. Bit 0 of the SIDH corresponds to the Preferred System flag used
- elsewhere in the NAM. Bits 6 and 5 of byte 0 are international code bits.
- Normally the SIDH is entered during programming of the phone as a 5 digit
- decimal number. Enter 0's to the left-most unused positions when
- reprogramming.
-
- L.U.
-
- Local Use Flag. Tells the cellular phone user if it must preregister with
- the system. Preregistration with the system means that a mobile must
- transmit its parameters to the Cellular System as soon as the power-up
- task and the control channel tasks are completed. "1" enables the flag.
- Usually set to "1".
-
- MIN MARK
-
- A 1-bit flag designating that MIN2 (area code) is always sent when making
- system access. "1" enables the flag. Usually set to "1".
-
- MIN2
-
- A 10-bit field representing the area code of the mobile ID number.
-
- MIN1
-
- A 24-bit field representing the mobile telephone number. MIN2 plus MIN1
- equals MIN, the 10-digit phone number.
-
- SCM
-
- A 4-bit field designating the Station Class Mark. A (3-Watt) 832 channel
- mobile unit typically will be 1000, a 1.2 Watt portable 1001 or a 0.6 Watt
- handheld 1010 or 1110 (discontinuous transmission, meaning push-to-talk).
- These are class I, Class II and Class III power levels respectively.
- With the SCM the cellular system determines whether or not a cellular phone
- can be switched to one of the 156 channels.
- Bit-1 is "0" for 666 and "1" for 832. (See cellular freq. list)
- Bit-2 is "0" for a mobile unit and "1" for a voice-activated
- transmit.
- Bit-3 and -4 identify the power class of the phone:
- "00" = 3.0 watts
- "01" = 1.2 watts
- "10" = 0.6 watts
- "11" is not assigned
-
- IPCH
-
- An 11-bit field designating the initial paging channel to be used if in
- the home system. Normally it is 334 for wireline systems, 333 for non-
- wireline systems. But most phones allow other settings for test purposes.
-
- ACCOLC
-
- A 4-bit field designating the overload class for the cellular phone. The
- intention of this entry is to allow the Cellular System to be able to
- determine priority in the event of a system overload, however it is currently
- useless as the system operators have generally not provided guidance for
- thier installers. The usual (and correct) system now in effect (in U.S.) is
- to use a "0" plus the last digit of the phone number. Test phones should be
- set at "10",emergency vehicles at "11","12" through "15" are reserved.
- (A class 15 system is supposed to be police, fire, or military).
- P.S.
-
- 1 1-bit flag designating the preferred system. If PS is "0", channels 334
- through 666(EVIL!!!) are used. If PS is "1" then channels 1 through 333 are
- used. Even numbered system numbers (B systems) require a PS of "0", odd
- system numbers (A systems) require a "1".
-
- GIM
-
- A 4-bit field designating the Group Identification Mark. This number tells
- the Cellular system how far to look in the SIDH to determine if it is roaming
- in a system which may have a roam agreement with the phone system. It is
- usually set to "10".
-
- LOCK DIGITS
-
- A 4-bit field designating the unlock code. The digit "0" in the lock code
- is represented by an "A" in the actual NAM hexidecimal data. A lock code of
- all "0" sometimes unlocks the cellular phone.(Note: Lock codes are 3 digits.
- When programming a phone use "0" as the first number.)
-
- E.E.
-
- A 1-bit flag designating that end-to-end signaling is enabled. End-to-end
- signaling means that the DTMF tones will be transmitted on the voice channel
- as well as being echoed on the handset. This feature in necessary for
- such services as Bank by Phone, activating answering machines and in third
- party long distance services such as Sprint and MCI. A "1" enables the flag.
- Usually set to "1".
-
- REP
-
- A 1-bit flag designating that repertory memory (speed dialing) in the
- cellular phone is enabled. And once a again a "1" enables the flag.
-
- H.A.
-
- A 1-bit flag designating that the horn alert feature in enabled. "1" enables
- the flag.
-
- H.F.
-
- A 1-bit flag designating that the handsfree option is enabled. A "1" enables
- the flag. Often, transceivers supplied as hands-free units require that
- this flag be left at "0".
