# WHATPORT(1076)

## NAME

port 1076 — DAB STI-C — The control half of the DAB digital-radio Service Transport Interface, registered by WorldDAB.

Protocol: TCP  
IANA registry

## DESCRIPTION

The Service Transport Interface (ETSI EN 300 797) carries audio, data, and service information from a service provider to a DAB ensemble provider. It splits into STI-D, the unidirectional data part that carries what gets broadcast, and STI-C, the bidirectional control and monitoring part that is not broadcast; 1076 is registered to WorldDAB for STI-C. You will only see it inside a broadcast contribution network, between playout and multiplexer equipment.

## EXPOSURE

**Do not expose.** STI-C controls what a DAB multiplex transmits. It belongs on a dedicated contribution link or broadcast VLAN, never on a public interface.

## CHECK

```sh
nc -vz -w 3 TARGET 1076
```
