Check SMPP SMSC trunk connection status

Check whether DIDWW is bound to your SMSC with an SMPP SMSC trunk. In an SMPP SMSC trunk, DIDWW connects and binds to your SMSC as an ESME. The status shows each session that DIDWW opens to your SMSC. Checking it does not reconnect the trunk.

Before you begin

• An active DIDWW account is required. Sign in to DIDWW.

• An SMPP SMSC trunk is required. If you do not have one, see Create an SMPP SMSC trunk.

• Your SMSC must accept the bind requests from DIDWW. See Accept SMPP SMSC bind requests.

Step 1: Open the status window

1. In the DIDWW User Panel, go to SMS > SMS Trunks.

2. Locate the SMPP SMSC trunk and click the Actions button next to it.

3. Select Check Status.

Step 2: Review the connection status

The Status Information window shows one entry for each session that DIDWW opens to your SMSC. When Transceiver mode is off, it shows a transmitter session (Type TX) and a receiver session (Type RX). When Transceiver mode is on, it shows one transceiver session (Type TRX).

Field	Description
Status	While DIDWW is bound, the bind type, for example BIND_TRX for a transceiver bind. While DIDWW cannot connect or bind to your SMSC, CONNECTING.
Sent, Received, Pending	Message counters for the session.
Type	Session type: TX (transmitter), RX (receiver), or TRX (transceiver).
System ID	System ID that DIDWW binds with, as entered in the trunk.
Connected	Date and time when the current bind was established. Shown while DIDWW is bound.
Online	How long the current bind has been active. Shown while DIDWW is bound.
Connection	IP addresses and ports of the DIDWW SMPP server and your SMSC.
Last Error	Reason for the last failed connection attempt, for example Connection timed out. Shown while DIDWW cannot connect or bind.

Next steps

• If Status shows CONNECTING, check the Last Error, the trunk’s connection details and credentials, and your firewall. See Accept SMPP SMSC bind requests.

• To receive SMS, assign the trunk to one or more DIDs that support inbound SMS.
