ISDN ANALYZER D1080 USER’S MANUAL REV. 5
For the PRIMARY (E1) access the TEI is always fixed since the
primary accesses are always of POINT-POINT type. The default
value is FIXED 0. Use the CHANGE option to select a fixed TEI
other than 0.

Profile: pto select the type of profile to be used for the
tests. The options available are:
− SPEECH: used to send voice information with a
connection in which although at 64Kbit/s at the user’s
interface, the signal can be properly manipulated within
the network (compression, coding, etc.). Press SPEECH
several times to select the audio coding between the A
and μ law (North America).
− 3.1K: used to send information for the 3.1KHz audio
band in transparent mode, that is without altering the
signal with the voice coding and compression techniques
that are typical of the SPEECH service (i.e. data
transmission with modem in voice band).
− FAXG3: used for FAX G.3 audio connections. It is a
teleservice that can be associated with the 3.1KHz carrier
service.
− 64Kb: for generic data connections at 64 Kbit/s. This
service supports the UDI (Unrestricted Digital
Information) transfer used for applications that need an
entirely numerical transfer from user to user at 64 Kbit/s.
The signal cannot be altered (i.e. compressed) during the
whole path. The word “Unrestricted” indicates that the
information is transferred with no alteration, that is the
service is transparent.
− 64K- OSI: for data connections with OSI protocols.
