2.14.16 Spectracom Technical Support for NTP
Spectracom does not provide technical assistance for configuring and installing NTP on Unix-
based applications. Please refer to www.ntp.org for NTP information and FAQs. Another help-
ful source is the Internet newsgroup at news://comp.protocols.time.ntp.
Spectracom can provide support for Microsoft
®
Windows-based time synchronization. See
spectracom.com for additional information, or contact Spectracom Technical Support.
Spectracom also offers an alternate Windows NTP client software package called PresenTense.
PresenTense software provides many features and capabilities not included with the limited func-
tionality of the Windows W32Time program, including alert notification and audit trails for the
PC’s time.
For more information on PresenTense, please visit spectracom.com or contact your local Spec-
