In general users are knowledgeable and receive any training as required. Both customers on this
system are sub-contractors in the building trades and have similar needs. The main office needs to
reach individual crews for job scheduling and changes. Individual crews need to reach the main
office to arrange for delivery of materials. Occasionally individual crews need to contact each other
to exchange tools or materials.
For consistency, all radios for each customer should be on the same sub-audible tone/code. Each
radio has a individual ANI, with DTMF ANI microphones and the ability to decode DTMF selective
calling. This provides the ability to selectively call the radio of interest. The goal is to provide
reliable operation with room to grow as customer requirements change. Operation must be logical
and consistent for the users. Programming must be setup to allow room for growth.
Multi-digit ANI is the way to go here. Phone-to-mobile, Mobile-to-Phone and Mobile-to-Mobile
calls are required. Multi-digit ANI gives individual addressing for identifying radios and additional
billing data.
Format of ANI:
•
ANIs should be fixed length (6)
•
ANIs include 4 digit Customer number and two-digit User number
User numbers are used for Overdial (Phone-to-mobile, Mobile-to-Mobile).
First we need to assign a Customer number for each user group. This identifies the user group each
radio belongs to. We also need to assign a block of user numbers for each user group with some
room for growth.
Customer number User numbers ANI numbers
1040 10 - 29 104010 - 104029
2040 50 - 59 204050 - 204059
User group 1040 has 11 radios now and will need more soon. We have allocated a block of 20 to
accommodate that expected growth. User group 2040 has seven radios and has no future growth
plans.
To keep the selective calling simple, we will use each radio's ANI for the Selcall capcode.
We now have our ANI numbering established, our user number blocks chosen and selective calling
format chosen. Let's go program up some users.
