Solutions
Does a school network room need a local GNSS NTP server?
Advantage
K–12, vocational, and university network rooms, teaching-building cabinets, labs, and one-card or exam systems need one inspectable LAN time base. SY-1231 delivers GNSS-disciplined NTP Stratum 1 with BeiDou+GPS and TCXO holdover on a single port sized for typical campus cabinets; campus security can share the same source. Specify coming 4096 only when a lab or campus TV plant requires IRIG-B / OCXO.
Primary: SY-1231 (school / campus)
Fit K–12, vocational, and university sites: network rooms, teaching-building cabinets, labs, exam systems, and campus security.
Not for Internet-only sync with no audit mandate; or must-have IRIG-B / multi-port dual supply (4096 / 8640).
Acceptance facts
- SY-1231-BG-T-S: BeiDou+GPS, TCXO, single 10/100M port, LAN NTP Stratum 1 after LOCK—sized for a campus network room or teaching-building cabinet.
- Lab PCs, exam/grading, one-card, and campus security can share one source. Planning cap 60; no IRIG, no OCXO, no PTP.
- Specify coming SY-4096 only if a physics/media lab or campus TV plant requires IRIG-B / OCXO. Ship 1231 for stock delivery.

FAQ
- Can the campus just use public NTP?
- Yes if egress is stable and there is no on-campus time-source mandate. Exam, one-card, and security search that must be auditable—or where UDP 123 is firewalled—should use a local GNSS NTP (SY-1231) in the network room.
- Which model should a school pick first?
- Primary: SY-1231. Look at coming 4096 only when a lab or campus TV spec writes IRIG-B / OCXO.
