5. Click the Apply Trunk Settings button to apply the changes to the selected trunk (or
click Apply to All Trunks to apply the changes to all trunks); the Stop Trunk button
replaces Apply Trunk Settings and the ‘Trunk Configuration State’ displays 'Active'.
6. To save the changes to flash memory, see 'Saving Configuration' on page 482.
7. To reset the device, see 'Resetting the Device' on page 479.
Notes:
• If the ‘Protocol Type’ field displays 'NONE' (i.e., no protocol type is
selected) and no other trunks have been configured, after selecting a PRI
protocol type, you must reset the device.
• The displayed parameters depend on the protocol selected.
• All PRI trunks of the device must be of the same line type (i.e., E1 or T1).
However, different variants of the same line type can be configured on
different trunks, for example, E1 Euro ISDN and E1 CAS (subject to the
constraints in the device's Release Notes).
• BRI trunks can operate with E1 or T1 trunks.
• If the protocol type is CAS, you can assign or modify a dial plan (in the
'Dial Plan' field) and perform this without stopping the trunk.
• If the trunk can’t be stopped because it provides the device’s clock
(assuming the device is synchronized with the E1/T1 clock), assign a
different E1/T1 trunk to provide the device’s clock or enable ‘TDM Bus
PSTN Auto Clock’ in the TDM Bus Settings page (see Configuring TDM
Bus Settings on page 231).
• To delete a previously configured trunk, set the parameter 'Protocol Type'
to 'None'.
