Programming
84 025-9368H
Program the radios for each user group with the proper sub-audible tone/code. Verify dispatch
operation (for 127.3 and D031). Verify proper decode of 74.4 in the Diagnostic menu.
Next we need to program our user groups for interconnect operation. Since we are using short sign-
on, we will have each user group in the Interconnect User database twice. Once for Mobile-to-Phone
operation and again for Mobile-to-Mobile operation. Our database will look like this:
User # User Group Function or privilege
User 10 Maintenance (Mobile-to-phone)
User 11 Maintenance (Mobile-to-mobile)
User 20 Manufacturing (Mobile-to-phone)
User 21 Manufacturing (Mobile-to-mobile)
User 50 Security (Mobile-to-phone)
User 51 Security (Mobile-to-mobile)
First, we need to remove an ANI conflict with User 1. Since we will be using short sign-on and “*”
for one of the ANIs, a conflict will occur since User 1 has no sub-audible decode for validation. To
do this we simply disable User 1 in the Interconnect User database.
Second, since we are on a PBX, we need to set PBX outside line digit to the digit(s) required to place
an outside phone call. This is in the Interconnect Telco System menu. The Model 748 will now
allow inside calls to be placed (typically three digits) with no restrictions. Outside calls (those that
start with the PBX outside line digit to follow all the normal toll restriction rules.
Now we are ready to setup our first user, Maintenance as User 10. Select User range and set the
range to “10”. Set Enabled to “Yes”. Our default ANI is correct, “*”. Set Answer type to “PTT”. Set
CTCSS/DCS decode and CTCSS/DCS encode to “127.3”.
