This dialing scheme is used to connect a VSB daughtercard to a generic Euro ISDN device 
using Euro BRI (E1 ETSI). Note that the two NT ports on Voice Daughtercard #1 are config-
ured as Point to Multipoint, whereas the two NT ports on Voice Daughtercard #2 are config-
ured as Point to Point. Each Euro BRI (Point to Point NT) interface connects only to one 
telephone line containing two B-channel lines.

The VSB daughtercard does not support static TEI assignments. The VSB daughtercard auto-
matically assigns TEI numbers, e.g., TEI 64, to BRI TE devices; these numbers will vary 
between 64 and 126. As per ITU-T Recommendation E.164 (1991), this VSB dialing scheme 
does not route based upon the ISDN subaddress supplementary service. Rather, the BRI 
devices connected to the VSB are responsible for ISDN subaddress routing. Subaddressing 
provides expanded addressing capacity beyond the standard ISDN number.

Installation of digital voice switching daughtercards, i.e., Euro BRI VSBs, must be installed to 
use this dialing scheme. VSB daughtercards also contain jumpers which must be configured in 
order to process VoIP calls using Euro BRI. See Chapter 2, “VoIP Daughtercards,” for details, 
and Chapter 4, “Setup and Installation” for further details on installation.
