Here's a used Symmetricom XLi Time/Frequency unit in good cosmetic condition. This unit has the Telco version of firmware installed, and that most commonly acts as a slave PTP IEEE-1588v2 device for sync purposes. It will also sync to an IRIG serial timecode signal if required (as shown in the screenshots). If the telco functionality is not required then the Telco Slave Card can be ignored and the unit will function as a standard XLi. This unit has the upgraded OCXO oscillator installed. It does not have a GPS card installed so it is shown being tested using an IRIG-B timecode source (as a PTP source was not available for testing). It has all the software based additional capabilities enabled - NTP server, Time Interval/Event Timer (TIET), Frequency Measurement, Programmable Pulse Output. The photos show the actual item for sale. The firmware supports a web based configuration interface. No unpictured cables, accessories or documents are included. Rack ears are provided as shown. In my testing I was able to achieve lock to IRIG-B 1344 timecode and screenshots of the results of my testing are provided below.

One of the great design benefits of the XLi is that, because of its variety of option cards, a company can customize it to fit to their specific application needs. Whether your application demands redundancy in power supplies, GPS, or any other function, all it takes is the proper configuration of cards.
XLi Option Cards The wide range of XLi option cards make it easy to tailor your system to support nearly every possible output/input needed for time and frequency applications, by combining option modules, oscillator upgrades, and two GPS receivers per unit. Plug-and-play cards and built-in XLi option card recognition software lets you swap out modules without modifying your operating system.
Plug and Play Configuration Configuration recognition software automatically detects the units setup, without modifications to the operating system, providing plug-and-play configuration capability for current and future application needs.
Freedom to Configure Modularity delivers the freedom to configure the XLi as a GPS timing receiver [GPS option not included], or a time code unit (TCU).
Seamless Integration The XLi seamlessly integrates into a network centric environment. The 10/100 Base-T interface is standard. Remote management is facilitated with the intuitive HTML web based interface as well as SNMP with an enterprise MIB. Command line interface is also supported via Telnet or the RS-232/422 serial port. The XLi can function as a Stratum 1 NTP server with addition of the NTS option.
Wide Range The standard XLi provides a wide range of time and frequency inputs and outputs such as: 1PPS output; time code input/output (IRIG A, B; NASA36) in both modulated (AM) and demodulated (DCLS) formats; programmable pulse rates; open collector alarm; front panel keypad and display; and more.
Modular Architecture for Easy Extensions The modular XLi architecture allows easy extension of the software and hardware in the field. Software updates are remotely administered. Existing and future hardware option modules can be added as needed by the user. The GPS timing interface is also modular which facilitates future upgrade to alternate Global Navigation Satellite Systems (GNSS), such as Galileo, when available.
