About the Call Book
The Call Book is required in Point-to-Point networks. While the Call Book is an option in Point-to-MultiPoint
networks, FreeWave strongly recommends using the Network ID feature in most applications. The
instructions provided in this section are for Point-to-Point mode only. Use of the Call Book for MultiPoint
networks is explained later in this chapter.
Using the Call Book offers both security and flexibility in determining how FreeWave transceivers
communicate with each other.
You must set the following for two FreeWave transceivers to communicate in Point-to-Point mode:
1. The Gateway's serial number must be listed in the Endpoint's Call Book (Endpoint column).
2. The Endpoint's serial number must be listed in the Gateway's Call Book (Endpoint column).
3. The Gateway must be programmed to call the Endpoint (Entry to Call option).
The Call Book allows you to incorporate up to 10 FreeWave transceivers, designate 1 to 4 Repeaters to use
with each transceiver, and designate which Endpoint the Gateway calls. To set the Entry to Call option,
select the number in the Entry to Call field, select All to direct the Gateway to call all Endpoints.
If a Call Book entry uses 3 or 4 Repeaters, then the total number of available Endpoint entries is reduced, as
an extra Call Book line would be in use for Repeaters #3 and #4. To set the Entry to Call option, select the
appropriate Entry number in the Entry to Call drop-down menu.
It is important that the Call Book slots (0-9) are filled sequentially starting with slot 0. When a Gateway is
instructed to Call All, it calls all Endpoints listed until it reaches the first serial number of 000-0000 (or a blank
slot). If a serial number is entered after the all zero number or as a Repeater, the Gateway does not recognize
it as a valid number.
To call an Endpoint through one or more Repeaters, that Endpoint must be called individually. The line
containing the Endpoint and Repeaters must be specifically selected in Entry to Call. With Call All selected,
the Gateway will not connect with any Endpoints through Repeaters. This is because, when Call All is
selected, the Gateway calls every Endpoint in the list and will connect with the first Endpoint that responds.
When calling through a Repeater, the Gateway must first call that Repeater and establish a communication
link with it prior to making contact with the Endpoint.
Programming Point-To-Point Extended Call Book to Use Three or Four Repeaters
In a Point-to-Point configuration, FreeWave transceivers can use up to four Repeaters. To use three or four
Repeaters, program the Call Book with the Endpoint's serial number, followed by the first two Repeaters. On
the next line enter 999-9999 as the transceiver to call. When prompted for the Repeaters enter the third and
fourth Repeaters in the link.
The illustration below shows a Point-to-Point link where an Endpoint is called through four Repeaters. In this
example the Gateway is calling the Endpoint, 571-3872, through Repeater 1, 901-1234, then Repeater 2,910-
0234, then Repeater 3, 571-3456, and finally Repeater 4, 571-4567. Entering the serial number 999-9999 in
line 1 instructs the Gateway to continue calling through the Repeaters programmed on that line.
