If you want the TA to answer inbound calls as often as possible, you can set the best-effort call answering bit as follows:
∙S119.3=0 - Answer calls only when numbers match (by default).
∙S119.3=1 - Best effort call answering.
Ambiguity Resolution Switch for Voice Calls (non-data)
For a voice 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. Sometimes, ambiguity of address matching may exist. This may happen if the &ZI numbers of the various protocols are either unassigned or not matched. In this case, users may wish to set the priority of answering a call by the analog adapter, Phone 1, or the analog adapter, Phone 2 (omni.net). The AT&Ln command sets the address ambiguity resolution flag:
Multi-Auto-Answering of Data Calls
For an ISDN data call, if the TA can exclusively determine the protocol to be used by means 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 the Additional Octet of Service Indicator), then the indicated protocol will be used. Otherwise, the Multi-Auto answering process will be invoked. The omni can monitor the B channel signal sent by the calling site.
The data call can be identified by the TA to be X.75, V.110, V.120, or PPP Async-to-Sync, conversion and MPPP.
Data Call Indication
Data calls are accepted the same way as in any TA. When alerted, the omni will send the first RING message to the DTE with a format as follows:
RING <CR><LF>
