The default MSN sub-address (or EAZ) for 1TR6 (Old German
ISDN) of the a/b adapters are as follows:
Phone 1: EAZ = 4 (&ZI7=4)
Phone 2: EAZ = 3 (&ZI6=3)
A global call is an inbound voice call without the information of
destination phone number (Called-Party-Number) which happens
more often than not on some switches when the calling site is on
the PSTN (analog telephone). By default, the TA128 will route the
global call to both the POTS ports (make them alert). The one that
picks up the phone earlier answers the call.
