undo isdn two-tei

View BRI interface view

Parameter None

Description Use the isdn two-teicommand to have the router requests the connected switch for a new TEI value before calling for a B channel.

Use the undo isdn two-teicommand to restore the default TEI handling practice on the BRI interface.

This command applies in the situation where the switch with which the router works is an ISDN NI compliant switch (the DMS100 for example) in North America. In this case, you must ensure that the TEI value assigned to each B channel is unique to ensure a successful MP channel call. Otherwise, only one B channel can be brought up and calling for MP fails.

By default, all the B channels on the BRI interface use one TEI value.

Example # Configure the router to request the connected switch for a new TEI value before calling to bring up a B channel.
