Why a hospital needs cabinet NTP: six must-haves
Mismatched HIS/LIS/PACS report times are the first hospital NTP driver. Monitors, connected devices, OR records, facilities, and accreditation/MLPS need one inspectable source.

Decision
Hospital weak-current: SY-1231. Clinical hosts use NTP; infusion pumps and ventilators typically enter via a time-synchronized gateway.
Notes
Primary need: one clock for HIS, LIS, and PACS. Disagreeing lab, imaging, or pathology times affect diagnosis and liability. Those servers and EMR hosts use UDP 123 to cabinet SY-1231.
Monitors / vitals: ECG, ICU, and telemetry need one clock to overlay waveforms and trends; anesthesia and medication times need the same base. Central stations use NTP; most bedside modules take the host clock.
Connected-device events: pump, ventilator, anesthesia, and dialysis alarms need accurate time for incident and nursing review. Most of these devices are not NTP clients; they enter via a time-synchronized clinical gateway or nurse station. List actual interfaces in the RFQ—do not treat every bedside device as an NTP client.
OR: video, anesthesia, and instrument logs should align with electrosurgery, anesthesia, and light-control stations. NTP-capable recorders and NVRs point to the cabinet time source.
Facilities / admin: access, attendance, fire, NVR, ward call, nurse intercom, pharmacy, and supplies can share the same 1231 if UDP 123 reaches.
Compliance: informatics rules, accreditation, and MLPS often require a shared time base; EMR, orders, and nursing times are legal evidence. This unit is an inspectable source plus Web CSV—not an MLPS assessment, accreditation verdict, or metrology certificate. Shipping SY-1231: design reply 3840 req/s; no IRIG, no OCXO, no PTP. Do not accept HIS against 1PPS nanoseconds. Commission with the hospital 10-step note.
