2 Click the ISDN settings button. The ISDN Settings dialog opens.
Note: The Switch Variant ‘ETSI EuroISDN’ is automatically selected and cannot be
changed. You do not need to modify the Service Code Table during initial configuration—
the defaults should be sufficient for connecting to a local exchange carrier.
3 Enter the following information:
•
User/Network Mode. Select one of the following:
• Select
User (the default) if you are configuring this port or ports to communicate
over an external BRI trunk to the CO.
• Select
Network if you are configuring this port or ports to communicate over an
internal BRI trunk to an ISDN device such as a fax machine, modem, and so forth.
•
B Channel Negotiation. Select Exclusive or Preferred from the drop-down list.
•
Send Calling Name. Select this checkbox if you want Wave to send the name
specified in the General Settings applet when calls are sent over this trunk.
• Specify the TEI (Terminal Endpoint Identifier) to use. TEI is a code supplied by an
ISDN device and is used by the service provider switch to identify the calling device.
Select one of the following:
•
Auto TEI. Auto TEI is obtained from the network via a message protocol, and is
typically used for point-to-multipoint configurations.
•
Fixed TEI. Enter a value between 0-63 inclusive in the text box. Typically, a TEI
value of 0 is used in a point to point configuration.
•
Stable in state 4. This option is not supported in this version.
