Where to Use It
First, the Sonoma must be deployed in a
cellular
or
PCS
IS-95 CDMA coverage area.
Cellular
is a
commonly used term implying that the frequency band for the base station carrier transmissions is
824-895 MHz. This is in contrast to
PCS
, which implies operation in the 1850-1990 MHz frequency
band. If available, the Sonoma uses the cellular frequency band because it provides much better
propagation characteristics in regards to building penetration and maximum receivable range from
the transmitter. In regions lacking cellular coverage, the unit can be set to receive the PCS signals.
In general, if your CDMA telephone works where you plan to install the Sonoma, then your Sonoma
will work properly there.
Because the Sonoma has been designed to operate in conjunction with existing public domain NTP/
SNTP client software that has been created for use with similar time servers, it may be used in any
computer network environment that is using TCP/IP protocols. Although client software is available
for all platforms, for the most precise applications, the Unix-like operating systems are best sup-
ported.
Client/Slave Software
The Sonoma has been designed to operate in conjunction with existing public domain NTP/SNTP cli-
ent software and may be used in any network environment that is using TCP/IP protocols. Although
client software is available for all platforms, for the most precise applications, the Unix-like operating
systems are best supported. For more information see
Chapter 3 - NTP, Setting Up NTP Clients on
Unix-like Platforms
and
Setting Up NTP Clients on Windows
. There is additional information about
NTP Client software at this link:

For PTP/IEEE-1588 applications, the Sonoma can interoperate with a variety of Slave software and
hardware. For more information on PTP Slave Software go to this link:
