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 TA128 can monitor the B channel signal sent by the calling site. The data call can be identified by the TA128 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 TA128 will send the first RING message to the DTE with a format as follows: RING [FM:[[Prefix]Calling-Party-Number][/Subaddress/]] [TO:[Called-Party-Number][/Subaddress/]] RING RING ...... The display of address information between the first RING and the second RING can be disabled by setting ATS84.4=1. The term [Prefix] is a predefined number string to be added in front of the Calling-party-number before sending it to the DTE. This is useful for some automatic dial-back-up systems. The number string can be assigned as follows: • ATCI - When and only when the type-of-number denotes an international number will this "Prefix" be added to the Calling-party-number before indicating it to the DTE. • ATCI - Disables the international number prefix-adding function.

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 TA128 can monitor the B

The data call can be identified by the TA128 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 TA128 will send the first RING message to the DTE with a
format as follows:
RING <CR><LF>
[FM:[[Prefix]Calling-Party-Number][/Subaddress/]]
[TO:[Called-Party-Number][/Subaddress/]] <CR><LF>
RING <CR><LF>
RING <CR><LF>
......
The display of address information between the first RING and the
second RING can be disabled by setting
ATS84.4=1
. The term
[Prefix] is a predefined number string to be added in front of the
Calling-party-number before sending it to the DTE. This is useful
for some automatic dial-back-up systems. The number string can
be assigned as follows:
•
ATCI<
Prefix> - When and only when the type-of-number
denotes an international number will this "Prefix" be added to
the Calling-party-number before indicating it to the DTE.
•
ATCI<>
- Disables the international number prefix-adding
function. (Default)
