can select, via the public network, one or more distinct terminals on
a single BRI line.
With its highly integrated, multi-function features, the TA128 can
be viewed 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
&ZI0=m assigns EAZ for X.75.
&ZI1=m assigns EAZ for V.110.
&ZI2=m assigns EAZ for V.120.
&ZI3=m assigns EAZ for PPP, MPPP.
&ZI4=m assigns EAZ for ISDN data, protocol auto-
detection.
&ZI5=m assigns EAZ for PPP, MPPP.
&ZI6=m assigns EAZ for Phone 2.
&ZI7=m assigns 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.
AT&ZI? can be used to display the EAZ numbers assigned by the
AT&ZIn=m commands.
The EAZ (last digit) of the destination address in an incoming
SETUP message will be checked with each protocol's EAZ. If there
is a match and the service indicated is compatible with this
protocol, the call will be accepted using the protocol.
O O NOTE
: EAZs must be assigned in exact order.
