Technical Reference for ZyXEL omni.net series

The ZyXEL Multi-Auto feature allows your omni.net to automatically detect calls, to identify calls as analog or digital and to route them accordingly.

When an analog call comes in, the omni.net sends the call to the analog port as the factory default, Phone 1 and then Phone 2 (for omni.net LCD/ LCD+M/Plus).

When a data call comes in, the omni.net automatically detects the PPP, V.110, V.120, and X.75 protocols, and negotiates a connection using the proper B-channel protocol, thereby freeing users from manual protocol configuration.

Answering a Call Using MSN

When answering an incoming call, the omni.net will first be identified if the calling number matches the MSN settings.

The Multiple Subscriber Number (MSN) supplementary service enables multiple ISDN numbers to be assigned to a single ISDN BRI line. It allows the caller to select, via the public network, one or more distinct terminals from a variety of terminal choices. Since the omni.net supports many different communication protocols and two analog adapters, each of these ports can individually be assigned to a different ISDN number using the following [AT&ZIn=s] AT command:

AT&Zin=s (where 's' is the MSN)

&ZI0=s

 

Assigns MSN 's', phone number for X.75

 

 

 

&ZI1=s

 

Assigns MSN 's', phone number for V.110

 

 

 

&ZI2=s

 

Assigns MSN 's', phone number for V.120

 

 

 

&ZI3=s

 

Assigns MSN 's', phone number for PPP, MPPP

 

 

 

&ZI4=s

 

Assigns MSN 's' for ISDN data, protocol auto-detection

 

 

 

&ZI6=s

 

Assigns MSN 's', phone number for Phone 2 (for omni.net LCD/Plus) and modem (for

 

 

omni.net LCD+M only)

&ZI7=s

 

Assigns MSN 's', phone number for Phone 1 (for omni.net LCD/ LCD+M/Plus)
