3 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 V7122 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).
4
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
Mediant & TP Series SIP Digital Gateways Release Notes).
5
Modify the relevant trunk configuration parameters according to your requirements.
6 To configure the different behavior bits: either enter the exact hexadecimal value of the
bits in the field to the right of the relevant behavior parameter, or directly configure each
bit field by completing the following steps:
a) Click the arrow button (-->) to the right of the relevant behavior parameter; a new
window appears.
b)
Modify each bit field according to your requirements.
c)
Click the Submit button to save your changes.
