#### 2. Function Description

The **SMPP (Short Message Peer-to-Peer)** protocol allows direct, high-volume SMS communication between your system and our messaging gateway. It's ideal for enterprise-level applications requiring stable, low-latency delivery.

**Key Features:**

* **SMPP Account**: A unique account name assigned to your SMPP connection (e.g., `DEV_YQ_MKT` for Marketing SMS).
* **SMPP Key**: The authentication key used to connect securely (keep it confidential).
* **Connection Address**: The server endpoint (IP + Port) where your system connects (e.g., `161.117.191.226:10776`).
* **TPS (Transactions Per Second)**: Maximum message throughput allowed per second (e.g., 100 TPS for Marketing, 10 TPS for OTP).
* **Connection Whitelist**: Restrict connections to specific IP addresses for security.
  * Default: `0.0.0.0` (allows all IPs)
  * Recommended: Add your server’s IP to enhance security
* **Online Count**: Number of active connections currently established.
* **Last Heartbeat Time**: Last time a heartbeat was received from the client (indicates connection status).

**Operations:**

* **Modify Whitelist**: Edit the list of allowed IP addresses for this SMPP account.
* **Refresh**: Reload the current configuration status.

> ⚠️ **Security Notice**: Never expose your SMPP Key or Connection Address. Use secure network configurations and firewalls.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc1.antgst.com/help-center/technology-access/smpp.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
