Ambiguity Resolution Switch For Voice Calls; Multi Auto-Answering Of Data Calls - ZyXEL Communications Omni TA128 User Manual

with the address of the incoming call, the TA128 will, by default,
ignore the call as it may be intended for other devices that share the
same S/T interface (S0 bus) with the TA128.
If you want the TA128 to answer inbound calls using all possible
protocols, you can set the best-effort call answering bit as follows:
Command
ATS119.3=0
ATS119.3=1

Ambiguity resolution switch for voice calls

For a Speech or voice-band-data call, if the &ZI number assignment
can tell which of the analog adapters is being addressed, then the call
will be delivered to the proper destination. But sometimes, ambiguity
of address matching may exist. This may happen if the &ZIn numbers
of the various protocols are either unassigned or not matched. In this
case, users may wish to set answering priority to an analog port. The
AT&Ln command sets the address ambiguity resolution flag as
follows:
AT&L0 - Analog adapter 1 has the higher priority to answer a voice
or voice-band-analog-data call; if analog adapter 1 is busy, the call
will be routed to analog adapter 2.
AT&L1 - Analog adapter 2 has the higher priority to answer a voice
or voice-band-analog-data call; if analog adapter 2 is busy, the call
will be routed to analog adapter 1.

Multi auto-answering of data calls

When an ISDN data call comes in, the TA128 can determine the
protocol to be used in one of two ways:
1. By way of the information conveyed by the SETUP message (for
DSS1, these include the Bearer-Capability, Low-Layer-
Compatibility, or High-Layer-Compatibility information
elements; for 1TR6, these include the Service Indicator as well as
an Additional Octet of the Service Indicator)
Function
Answer call only when number matched. (default)
Best effort call answering.
