Control of EAZ (ENDGERÄTEAUSWAHLZIFFER)
EAZ (or terminal selection code) is the last digit of an ISDN phone number in 1TR6. Usually
EAZ=0 indicates that a global call (any terminal on the S0 interface), which is service-compatible
with the incoming call, can answer the call.
Other values of EAZ (1,2,....,9) provide the possibility for assigning multiple ISDN numbers to
a single ISDN BRI line. A calling user can select, via the public network, one or more distinct
terminals on a single BRI line.
With its highly integrated, multifunction features, the Model XM128 modem can be imagined as
a “black box” containing multiple distinct terminals. Each of these “internal terminals” can be
assigned one EAZ using the command AT&ZIn=m, where n=0-7 and m= 0-9.
Command Function
The following commands are used for assigning EAZs:
• &ZI0=massigns EAZ for X.75
• &ZI1=massigns EAZ for V.110
• &ZI2=massigns EAZ for V.120
• &ZI3=massigns EAZ for PPP, MPPP
• &ZI4=massigns EAZ for ISDN data, protocol auto-detection
• &ZI5=massigns EAZ for PPP, MPPP
• &ZI6=massigns EAZ for PHONE 2
• &ZI7=massigns EAZ for PHONE 1
The default EAZ of each protocol is as follows:
• &ZI0=1 for data
• &ZI4=2 for data
• &ZI6=3 for the analog adapter, PHONE 2
• &ZI7=4 for the analog adapter, PHONE 1
• T&ZI? for displaying the EAZ numbers assigned by the AT&ZIn=m commands
