An operations layer that complements your TOS.
PreGate does not replace the systems your port runs. The TOS stays the source of truth; each connection is built, tested and accepted at your site.
Where each connection stands today.
The named systems are connection targets. No connector has passed customer acceptance yet; we will show version, message scope and acceptance result here as each one does.
| System | Direction | Data | Today |
|---|---|---|---|
| TOS: GullsEye, Navis N4, TOPS, Tideworks, CyberLogitec; others through an adapter | TOS → PreGate | Work orders, hold and release | Interface in the product, tested against a simulator |
| TOS, writing back | PreGate → TOS | Gate events, pre-notification | Interface in the product, tested against a simulator |
| TOS, park charges | PreGate → TOS | Park charge accrual | Interface in the product, tested against a simulator |
| Customs systems: BİLGE, Guichet Unique and others | ↔ | Approval and hold status | Interface in the product, tested against a simulator |
| PMIS, port authority | ↔ | Entry and exit approval, fee sharing | Interface in the product, tested against a simulator |
| SMS, e-mail and other messages | PreGate → | Notifications to hauliers and drivers | Interface in the product, tested against a simulator |
| OCR, ANPR, RFID, barrier, weighbridge | ↔ | Readings and barrier commands, through Edge | Interface in the product, tested against a simulator |
| Maps and live traffic | → PreGate | Expected arrival | Interface in the product, tested against a simulator |
| ERP, payment, SSO, EDI, webhook | ↔ | By agreement with the site | Interface in the product, tested against a simulator |

How a connection is built
Interface first
Every external system sits behind an interface in the product; the gate logic never talks to a vendor API directly.
Adapter per site
The adapter for your TOS, customs or PMIS is commissioned during deployment and tested against your environment.
Last known state
If the TOS cannot be reached, the gate uses the last known hold status instead of stopping.
Decisions recorded
Every gate decision is an append-only event with its reason.

Next step
Make your port's flow
measurable.
For a pilot scope we need daily and peak trucks, number of gates, park capacity, transaction types and TOS version.
