Overview
You would like to know whether tp_stop and tp_start resets the m3ua connections. You were upgrading the MSC and saw that the m3ua connections were down. You tried to restart the connections on the server by restarting the application using the commands tp_start and tp_stop but the connections did not recover.
Information
Yes, tp_stop would disconnect m3ua connections. tp_start reads the m3ua configuration from the host config file on the smsc node and attempts to establish all m3ua connections defined.
Only the textpass process that uses tp_stop and tp_start can be stopped/started to re-establish m3ua connections:
- tp_stop --textpass
- tp_start --textpass
Other processes like tp_hub, tp_ams, tp_faf etc do not interfere in m3ua setup.
