ACC TRX Mode for SMS

Hi 

With reference to the ACC documentation link, https://helpx.adobe.com/campaign/kb/sms-connector-protocol-and-settings.html we understand that ACC only supports separated TR-RX mode of in SMPP connector. 

Question is, is there any work around for this by going via a bridge middle ware solution to be able to connect to the end SMS Gateway via SMPP TRX mode? 

Any documentation/implementation suggestion is much appreciated. 

Thanks
