Board Configuration
68 AltiWare OE System Administration Manual
The choices in the list depend on the specific switch and your long distance
service provider. An example of such service includes AT&T Megacom.
If your CO requires specific NSF features to be present in the
call setup packet, please contact AltiGen’s Technical Support
department with such information from the CO and they will
help you configure it.
Setting a TEI
The TEI (Terminal Endpoint Identifier) defines which terminal device
is communicating with the CO switch for a given message. PRI messages
involve point-to-point configuration in which each side already knows the
source of any message received. ISDN messages involve point to multi-
point locations in which the source can only be identified by the TEI.
Select one of the following TEI settings:
• Default setting - this is the recommended setting
• Manually set to - should always be set to 0. Typically, a zero (0) is
used for TEI on a PRI connection. In some cases where a shared D
channel is used, other TEI values might be required to identify
which span will be used for a call.
• Assigned by CO switch - do not use this setting unless advised by
your CO.
