To configure the parameters of a specific trunk, from the trunks displayed on the top,
select the trunk you want to configure by clicking the Trunk's Status indicator. The first
parameter named 'Trunk ID' changes according to the trunk you click. The parameters
displayed are for the selected trunk only.
4 To modify the selected trunk's parameters, click the Stop Trunk button; the trunk is
stopped, the status of the parameter 'Trunk Configuration State' changes to 'Non Active',
the parameters are no longer grayed and can be modified and the Apply Trunk
Settings button appears at the bottom of the screen.
When all trunks are stopped, the Apply to all Trunks button also appears at the bottom
of the screen.
If the trunk can't be stopped because it provides the gateway's clock (assuming
the V6100 is synchronized with the E1/T1 clock), assign a different E1/T1 trunk
to provide the gateway's clock or enable 'TDM Bus PSTN Auto Clock' on the
TDM Bus Settings screen.
To assign a different E1/T1 trunk that provides the gateway's clock, access the
'TDM Bus Setting' screen and change the 'TDM Bus Local Reference' number
to any other trunk number (this operation can be performed on-the-fly).
5
Select the 'Protocol Type' you use. Note that different trunks can be defined with different
protocols (CAS or ISDN variants) on the same gateway (subject to the constraints in the
V6100 Release Notes).
When modifying the 'Protocol Type' field, the menu is automatically updated
according to the selected protocol (ISDN, CAS or Transparent). Additional
parameters are appropriate to the selected protocol type.
6 In the 'Framing Method' field, select the 'Framing Method' you use (for E1 trunks, always
set the Framing Method to 'Extended Super Frame').
