How to connect an OZX connection (video tutorial)

The following short video shows the steps you need to create to setup an OZX client connection in Ozeki 10 SMS Gateway. The video starts with the login form and takes you all the way to sending your first SMS test message over the newly created SMPP connection.

Detailed setup instructions

Setting up an SMS connection in Ozeki SMS Gateway is a relatively simple procedure. You need to login to the SMS gateway using a web browser as administrator, and you need to perform a few simple steps. For configuration we recommend to login using the administrator account. The administrator account username is "admin", and the password is the one you provided during install.

How to create a new OZX connection

To create a new OZX connection after login, you need to click on the 'Add new connection' link in the management console of the Ozeki 10 SMS Gateway app. This will bring up a list of available protocols. You will have to select OZX client from the list. Note, that an OZX client connection is used if you wish to connect your SMS gateway to an SMS service provider over the Internet. (If you wish to provide an SMS service, and you want your customers to connect to your SMS gateway over OZX, you need to setup an OZX user account and you need to configure an OZX service.)

Select the 'OZX Client Connection' from the list and click on install next to it.

Configure your OZX connection

In order to configure your OZX connection, you need to provide the host name and port number of the OZX service, your OZX credentials and you must specify telephone number associated with this connection. There could be more than one phone numbers associated with this connection. In this case provide the first one and check the overridable checkbox. If this checkbox is checked, you will be able to use all phone numbers as sender IDs.

OZX connection configuration steps:

1. Select the General tab on the OZX connection form
2. Give a name to this OZX connection
3. Enter the OZX hostname
4. Enter the OZX port number
5. Provide your OZX username
6. Enter your password
7. Assign a telephone number to this OZX connection
8. Click OK

It is important to mention that the OZX hostname and port plus the username and password are provided by your SMS service provider. For example, if you contact Vodafone, and ask for an OZX SMS service, you will sign a contract with them, and often an attachment of this contract will contain the connection following information. If you subscribe to an SMS service on-line, you will likely find this information in the on-line control panel of your SMS service provider. Of course, you can always ask your SMS service provider in e-mail and ask what the OZX server connection details are.

Check the OZX log

Once the OZX connection is configured, you should check the OZX connection log to see if the system connected properly to your SMS service provider. If the system connected properly, you would see the "Connection online" log entry. The SMS connection logs can be found in the following directory in Windows: C:\Program Files\Ozeki\Data\Logs\Connections\. In this Event tab of the OZX connection's details page, you can see a preview of the log. This page contains the last 100 log entries. Note that the OZX log files are rotated to save disk space.

Send a test SMS message

Once your connection is connected, you can check to see if it is ready to deliver SMS messages by sending a test SMS. To send a test SMS message, you need to open the Admin user, and you need to enter the phone number and message text. It is recommended to provide the phone number in international format. This means the phone number should start with a plus sign followed by a country code. If your local phone number starts with a 0, it is likely that you will need to drop the 0 prefix. For example, if your UK phone number 07958663698, you would send the test SMS to +447958663698.

You might ask why the message text should be less than 160 characters. This is because GSM system was designed to send 160-character long text messages. If a message is longer, it will be split into multiple message segments, and will be delivered in more than one SMS message.

After the message is successfully sent, you should check the OZX logs. The OZX logs will reveal the low level OZX messages, that are used to pass the message content to the SMS service provider. These messages are also called an OZX PDU (OZX protocol data unit). If there is a problem with message submission, your SMS service provider will ask for the OZX logs. In this case, you need to send the OZX PDUs to them. For every SMS submission, two OZX PDUs will appear in the log.

FAQs

What is an SMSC?

A Short Message Service Centre (SMSC) is a network element in the mobile telephone network which delivers SMS messages. It has SMS message forwarding and SMS message storing functionality.

In the world of mobile communication, a fundamental yet often unseen element plays a vital role in ensuring the smooth delivery of text messages: the Short Message Service Centre (SMSC). Functioning as a central hub for a wireless network or SMS service provider, the SMSC acts as the conductor of the entire messaging process. When a text message is sent, it is first directed to the SMSC. This intelligent intermediary then determines the most efficient route for the message to reach its intended recipient, potentially involving other SMSCs within the broader network infrastructure. Importantly, the SMSC possesses storage capabilities. In situations where the recipient's device is unavailable, the message is held for a predefined period (typically up to a week) to ensure successful delivery once connectivity is restored. While network operators often maintain their own SMSCs for optimal control, the use of third-party SMSC services is also a possibility. Although the SMSC address, formatted similarly to an international phone number, serves as a unique identifier for a network's messaging centre, user intervention is generally not required. Most mobile phones come pre-configured with the correct SMSC address stored on the SIM card, allowing for a seamless text messaging experience for users.

Can I operate my own SMSC?

Yes, you can.

Setting up a private SMSC requires a computer connected to the mobile network and specialized software. This software acts as the brain of the operation, routing messages efficiently and communicating with the network using industry-standard protocols like SMPP, UCP, or CIMD2.

Benefits for Businesses:

• Cost-Effectiveness: For companies sending a high volume of SMS messages, private SMSCs can offer significant cost savings compared to traditional SMS services.
• Customization: Private SMSCs provide greater control over message delivery and security compared to relying on third-party providers.
• Integration Flexibility: The software often integrates with various applications using APIs (Application Programming Interfaces) like HTTP, C#, or PHP, allowing businesses to automate SMS communication within their existing workflow.

Do I have to pay for SMS messages if I operate my own SMSC?

Yes

While SMSCs handle the magic behind sending text messages, there's a cost involved when your message reaches the mobile network. This fee is typically charged on a per-message basis. You'll pay this fee either to the mobile network operator directly or to the SMS service provider who allows you to connect your system to the network.

To send SMS messages from your SMSC, you need a way to connect to the mobile network. This connection isn't possible without signing up for a service offered by a mobile network operator or an SMS service provider. Think of them as the gatekeepers to the network, ensuring proper routing and billing for your messages.

This rephrases the text to be more user-friendly and avoids technical jargon. It emphasizes the per-message cost and the necessity of a connection service.

Can I connect to the SMSC of a mobile network operator (MNO)?

With the right tools in place, you can connect your system to a mobile network operator's SMSC (Short Message Service Centre) and start sending SMS messages. Here's what you'll need:

• Internet or Leased Line Connection: A reliable internet connection or a dedicated leased line provides the pathway for your messages to reach the network.
• IP SMS Protocol: Specialized protocols like SMPP, UCP, or CIMD2 enable communication between your system and the SMSC. These act like a common language for message exchange.
• Mobile Network Operator Agreement: To ensure proper routing and billing, you'll need a formal agreement with a mobile network operator. This agreement grants you permission to connect to their SMSC and send messages through their network.
• SMS Sending Fees: Be prepared for per-message fees associated with sending SMS messages through the network operator's SMSC. These fees cover the cost of delivering your messages to their destinations.

Can I connect to the SMSC of a mobile network operator through SS7?

When you send a text message, it relies on a hidden communication system within the mobile network. Here's a breakdown of two key protocols involved:

• SS7: Imagine a special language used by phones and network components to talk to each other. This protocol, called SS7, coordinates various tasks behind the scenes, including routing SMS messages between the SMSC (Short Message Service Centre), the HLR (Home Location Register), and mobile phones. Traditionally, SS7 uses dedicated E1 ISDN lines for communication. However, a newer version called SIGTRAN transmits data over the internet.
• IP SMS Protocols: For connecting your system (like a business application) to send SMS messages, SS7 isn't the right fit. Instead, you'll need a more user-friendly option. This is where IP SMS protocols come in. Think of them as universal translators. Protocols like SMPP, UCP, or CIMD2 allow your system to communicate with the SMSC over the internet, eliminating the need for the complex SS7 environment.

SS7 plays a crucial role within the mobile network, but for connecting an external system to send SMS messages, IP SMS protocols are the way to go. They provide a simpler and more accessible way for your system to interact with the network's messaging centre.
