SMPP accounts associated with each customer are defined in the Customers > SMPP accounts section. These are the SMPP accounts that customers can use to connect to your SSG instance and send or receive SMS.

Each SMPP account dialog has the following tabs:

• Main - customer, SMPP credentials
• Parameters - submission rate
• TLVs - TLV handling
• Security - allowed IPs
• Rules/Blocking - rules specific to account, blocking of content
• Webhooks - MT SMS web hook, MO and DLR webhooks
• Reporting - graph of traffic
• MO SMS - inbound numbers associated with account
• CUG - closed user group of MSISDNs
• Routing - routing for the service used by the account
• Other - other information, master account enable/disable

Account information to give to customers

After you have set-up a customer's SMPP account, you should provide them with the following information as a minimum:

• system ID
• password
• hosts and port
  • all of the SSG's customer endpoints are available to your customers and we recommend that you provide the details for at least two of these to your customers
  • port 2775 should be used for SMPP and port 8775 should be used for SMPP over TLS
• maximum submit TPS (SMS/sec) configured on customer's account

Advice for reliable customer connections

To ensure that your customers are minimally affected by any node/server failure on the SSG platform or internet issues, they should connect to your SSG instance in such a way that they:

• remain connected to two separate sites of the SSG platform at all times, or
• failover to a different site of the SSG platform when unable to connect to their preferred site.

When failing over to a different site, attempts should be made to connect to the preferred site before and after a connection is made to the secondary site.

Give your customers two SMPP account that they can use with a single site (failing over to another site when necessary) or at the same time with two sites.

Where a customer requires that they are connected to your service at all times, give the customer four SMPP accounts that they can use to connect from two separate sites on their side to two separate SSG sites.
