DETAILED TYPE 99 OPERATION

For example, assume the paging number to be 123. The first digit of the paging number is a 1. Look in Table 3 and read down

Table 4 - Tone Generator Frequencies

The Motorola tone format is illustrated as follows:

AND PROGRAMMING

The original Type 99 programming provides individual, group and super group call decode. The Motorola format two- tone sequential signaling schemes can also be decoded.

The MDS Conventional radio can be PC programmed with up to two separate tables of tones. Either the GE Type 99 format or the Motorola format can be assigned to each tone table. The tone decoder (Individual, Group and Super Group for the GE format or Individual, Group and Quick Call for the Motorola format) can be enabled individually for each channel. Once enabled, one of the two tone tables can be selected for each channel.

The Group Call format allows communication with all radios within a subgroup. The Super Group Call (in GE tone systems) or Quick-Call (in Motorola tone systems) allows com- munications between all radios in a system.

the column labeled "100’s Digit" to a 1. Read horizontally across the column labeled "10’s Digit". The tone group is B. The second digit of the paging number is a 2. The tone number is B2. Look in Table 4 and down the column labeled "Tone Designa- tor" to find B2. Read horizontally across the column labeled "Tone Frequency". The first tone frequency is 787.5 Hz.

To determine the second tone frequency look in Table 3 and as before, find the first digit of the paging number (1). The second tone group is A. The third digit of the paging number is a 3 and the tone Designator is A3. In Table 4 read down the column labeled "Tone Designator" and find A3. Read horizontally across the column labeled "Tone Frequency". The second tone frequency is 802.5 Hz. For different paging numbers, locate the first digit in the "100’s Digit" column and determine the tone frequencies as described in the example.

GE TYPE 99 FORMAT

Tone frequencies in the GE tone system fall within the range of 517-5 to 997.5 Hz.

In the GE tone format, the first tone may be from tone group A (for Individual or Group calls) or from tone group C (for Super Group calls). The second tone may be from tone group B (for Individual calls) or from tone group D (for Group and Super Group calls).

Individual Call

Tables 5 and 6 may also be used to determine the tone frequencies. The first digit of the code determines the tone group used in the code (see Table 5). Then Table 6 is used to determine the actual tone frequencies. For a code of 124, the tone groups used are shown in Table 5. Tone A and Tone B are both located in tone group 1 and Tone B is a tone number 4. Refer to the following examples for additional information.

Example 1 - Code 098:

The digit "0" in Table 5 (First Digit of Code) shows that Tone A is in Tone Group and Tone B is in Tone Group 2 (see Table 6).

Tone D

Tone D is a diagonal tone used (in GE tone systems only) when the first and second tone frequencies are the same. The standard frequency for Tone D is 742.5 Hz, but may be programmed with any tone frequency.

MOTOROLA FORMAT

Tone frequencies in the Motorola tone system are within the range of 288.5 to 1433.4 Hz. In the Motorola tone format, the first tone may be one of three tones: A for Individual Call, B for Quick Call and C for Group Call. The second or final

Tone number 9 in Tone Group 4 is 524.6 Hz. Tone number 8 in Tone Group 2 is 879.0 Hz.

Example 2 - Code 265:

The digit "2" in Table 5 shows that both Tone A and Tone B are in Tone Group 2.

Tone number 6 is 788.5 Hz.

Tone number 5 is 746.8 Hz.

tone is B in all cases.

NOTE

The MDS radio is able to recognize the A,B, and C tones. Individual, Group and Quick Call formas may be used simultaneously.
