4.3. Using the Call Book in Point-to-Point Networks
Using the Call Book offers both security and flexibility in determining how FreeWave radios
communicate with each other.
Important!: The Call Book is required in Point-to-Point networks.
FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,
FreeWave strongly recommends using the Network ID feature in most applications.
If a large MultiPoint network is implemented using the Call Book and a radio needs to be added to or
replaced in the network, each radio in the network must be physically reprogrammed and the new
serial number entered in the radio's Call Book.
This can be a time consuming process and can cause a delay in getting the network back up and
running.
Because the Network ID does not use serial numbers, MultiPoint Master radios and Repeaters may
be added or replaced without reprogramming each Slave radio in the network.
l The Call Book allows a maximum of 10 FreeWave radios.
l Designate 1 to 4 Repeaters to use with each radio.
l Designate which Slave the Master calls.
These settings are required for two FreeWave radios to communicate in Point-to-Point mode:
1. The Master radio serial number must be listed in the Slave radio's Call Book or Slave
Security is turned off in the Slave.
2. The Slave serial number must be listed in the Master Call Book .
3. The Master must be programmed to call the Slave (Entry to Call option).
a. Select the number in the Entry to Call field, select All to direct the Master to call all
Slave radios.
Note: To set the Entry to Call option in the terminal interface, press <C> at the Call Book
menu, followed by the menu number corresponding to that Slave.
To call any available Slave in the list, press <C> then press <A> to direct the Master to Call
All.
It is important that the Call Book slots (0-9) are filled sequentially starting with slot 0.
l When a Master is instructed to Call All, it calls all Slave radios listed until it reaches the first
serial number of 000-0000 (or a blank slot).
l If a serial number is entered after the all zero number or as a Repeater, the Master does not
recognize it as a valid number.
Note: When entering numbers into the Call Book, define only the Repeaters in the Master's Call
Book.
The Slave's Call Book only requires the Master serial number.
A Repeater need not have anything listed in its Call Book.
