CommSync II- D® Model 407

CommSync II- D® Model 407

The CommSync II -D can provide a wide variety of time and frequency output signals with 8 I/O Module slots and 200+ available Option Modules.Utilized as a Primary Reference Source (PRS), the CommSync II-D provides either Standard Positioning Service (SPS) or the very latest in GPS military technology; SAASM Precision Positioning Service (PPS) (for authorized users only).

Description

Product Description:

The CommSync II-D delivers all the performance and functionality of the CommSync II in a 2U chassis. The heart of the CommSync II-D is the GPS Time and Frequency (GTF) reference module. The GTF is a hot-swappable, front panel plug-in module (with two slots available for redundancy). It is a self-contained module with Quartz Crystal (OCXO) or Rubidium Atomic oscillator options, as well as Civil or SAASM MPE-S GB-GRAM, or SAASM Force 22E MRU GPS receiver options. Dual Power Supplies and Reference Modules provide redundancy with uninterrupted automatic switchover.

Like our flagship CommSync II, the CommSync II-D provides a frequency accuracy of 1E-12 and a time accuracy of
< 50 ns Peak to UTC.  Additional I/O slots can be utilized by configuring a slaved CommSync II-D with Distribution Time and Frequency (DTF) modules.

For Monitor and Control functions there is an RS-232 communications port on the front panel of the GTF/DTF module, a front panel keypad and display, as well as optional Gigabit Ethernet plug-in modules providing Telnet, SNMP, PTP v2 (1588-2008), and Network Time Protocol. Zyfer Monitor (FEI-Zyfer’s remote access utility) provides complete remote control, including system status, setup, alarm logging and user management over a standard TCP/IP connection.
