## Check on configuration data for trunks

When checking configuration data for trunks verify the following:

- That the selected line signalling diagram agrees with the public network for the relevant trunk and the country specific session is loaded.
- That the country specific RASC session is loaded.
- This can vary depending on the type of public exchange which type of trunk is connected.
- Signalling to public exchange; decadic, DTMF, MFC/MFE or ISDN.
- Supervision times.
