TEI Topology
The Terminal Endpoint Identifier (TEI) can be configured to either:
■Automatic - The Terminal Endpoint Identifier (TEI) is negotiated
automatically between the 833IS and the carrier.

Directory Number1, Directory Number 2
To have the router verify a called-party number in the incoming setup message for
ISDN BRI calls, the directory numbers need to be configured. For the US-NI-1 and
DMS-100 switch types, both directory numbers must be set. For the 5ESS switch
type, you may need to set none, one, or both directory numbers depending on your
ISDN subscription. For the NET3 and NTT switch-types, all incoming calls will be
accepted if the directory numbers are not specified.
