Technical Reference for ZyXEL omni.net series

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 with no destination phone number (Called-Party-Number) which may happen on some switches when the calling site is on the PSTN (analog telephone). By default, the omni.net will route the global call to both the POTS ports (making them alert). The phone port that picks up the phone earlier answers the call.

German ZyXEL customers: The inner two pins of the RJ-11 are used for the Tip and Ring (or 'a' and 'b' signals in Germany, the two signals that connect to a telephone set). This is the standard pin assignment, but some BZT-approved telephones use the outer two pins for a and b. If this is the case, use the attached TAE adapter which has a unique interface definition or use an RJ-11 cable that connects the inner pins on one end and the outer pins on the other end.
