CXCELDEB Command - Cellular Connection Anti-bounce

Configures anti-bounce times for the CEL signal (GPRS/LTE connection status).

What is it for?

Use case	Description
🚫 Avoid false alarms	Ignore signal micro-cuts
📊 Connectivity monitoring	Alert only on real disconnections
🛣️ Routes with variable coverage	Tolerate momentary signal-free zones
⏱️ Report stability	Confirm status before notifying

Description

Allows defining time delays before a cellular connection status change generates a trigger in the event engine, avoiding false positives due to momentary disconnections.

Similar to the operation of IT Command for digital inputs.

Parameters

Parameter	Description	Range	Unit
aaa	Connection delay (positive edge)	001-999	seconds
bbb	Disconnection delay (negative edge)	001-999	seconds

Examples

Standard delay


>SCXCELDEB010060<
// aaa=010 → 10 seconds to confirm connection
// bbb=060 → 60 seconds to confirm disconnection

The longer disconnection delay avoids alerts due to momentary signal losses in tunnels or low coverage areas.

Fast detection


>SCXCELDEB005005<

Detects changes with only 5 seconds of stability.

Avoid micro-cut alerts


>SCXCELDEB010600<

Connection: Triggers after 10 seconds
Disconnection: Triggers after 10 minutes (avoids alerting on momentary cuts)

Use in Event Engine

The CEL signal can be used in conditions:


>SEVT1W;@ALL;WHEN;CEL;BECOMES;TRUE<

Generates alert when connection is established (respecting the configured delay).
