Tyco Electronics M/A-COM, M7300 Series 9.14 MOBILE DATA

1. Follow the procedure in Sending a Telephone Interconnect Call (Trunked Mode Only) to

establish a connection to the telephone system or consult the system administrator for the procedure

to access a dial tone on the trunked or conventional system.

2. Overdial numbers are transmitted using either method as follows:

METHOD 1: Press and hold PTT while entering the overdial number sequence from the keypad.

This method sends DTMF tones during individual, telephone interconnect, trunke

group, or conventional channel calls. Anytime the PTT button is pressed and held,

the keypad is enabled for DTMF entry.

METHOD 2: Press PHN to enter the overdial select/entry mode and follow the selection mode

rules to call up a stored number from the phone list or to directly enter the overdial

digits. Press PTT to send the overdial sequence once. If the number needs to be

transmitted again it must be selected or entered again (this prevents unwante

numbers from being sent the next time the PTT button is pressed during the call).

This overdial select/entry mode remains active until the call is dropped, cleared, or MENU is pressed. The

overdial select/entry mode can be re-entered if the call is still active by pressing PHN.

Individual call ID numbers, telephone numbers and other number sequences for overdialing are stored in

the special call lists when programming the radio. The first ten entry locations of these lists can be

changed by the radio operator. The keypad is used when adding, changing and storing numbers in these

entry locations.

Use the following procedure to store a number in one of the first ten entries of a special call list:

1. Press IND or PHN to enter the individual call list or the phone call list. The selection mode rules

apply.

2. Scroll through the list using the ramp control until one of the first ten entries is reached. NO

ENTRY is displayed if the location is empty.

3. Enter the desired number. If necessary, a pause can be entered by pressing and holding 0-9, (*), or (#)

until an underscore appears in the display. The individual call list entries will accept up to 5 digits.

The phone call list entries accept a combination of up to 31 digits and pauses.

4. Press and hold MENU until the display changes indicating that the number has been stored.

5. Repeat the steps above if the number stored in an entry location needs to be changed.

9.14 MOBILE DATA

The M7300 Series mobile radios, when operating in the EDACS configuration, permit either voice or data

calls to be transmitted or received. The radio can handle only one type of call at a time; however,

selection of either data or voice is selected transparently by the operator through normal usage of the

radio. Data communications is not supported in the conventional mode.

The mobile radios can be connected to Mobile Data Terminals (MDT) or to a host computer. Any RS-232

compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) can be

connected to the mobile radio. Support for MDTs or host computers is a programmable option per radio.

Additionally, radios programmed for host computers can also be programmed for data only operation (no

voice calls transmitted or received).
