Trouble isolation and correction 9-55
With multi-party ringing, the SMS sends the RCS signals to execute a loss
and ANI/coin test after the ringing test. These tests determine if the correct
termination connected at the RCS.
Coin collect and coin return
The coin collect and coin return test checks the ability of RCS coin cards to
provide coin collect and coin return functions. The SMS sends the RCS an
A- and B-bit pattern to execute a coin return or coin collect function.
For coin collect, the RCS provides an absorb-PTPG termination. For coin
return, the RCS provides a reflect-NTPG termination. When a
reflect-NTPG is present, the RCS must perform the following actions. The
RCS must detect coin presence and send the SMS an A- and B-bit that
indicates coin presence. The loss and coin presence tests can determine if
the correct terminations occurred in the RCS.
Product specified test tools
Many tools can test components from peripheral modules and remote
terminals. There are no product-specified test tools that test the SMS-RCS
configuration.
