5: BSC 2780/3780 DLI Functions
DC 900-1340I 133
FNo answer tone (DLI_ICP_ERR_NO_ANSWER)
E No dial tone (
DLI_ICP_ERR_NO_DIALTONE)
C Invalid command or configuration (
DLI_ICP_ERR_BAD_MODEM_RESP)
V.25bis Support
If the modem type option is set to V.25bis, the Autodial Start command causes the
BSC 2780/3780 software to insert the character string “CRN” at the start of the autodial
string. The BSC 2780/3780 software then sends the autodial string to the modem and
waits up to 60 seconds for CTS to be detected. The BSC 2780/3780 software recognizes
the following responses from the V.25bis modem type:
INC Incoming call (DLI_ICP_ERR_INCOMING_CALL)
CFI FC Forbidden number (DLI_ICP_ERR_BAD_MODEM_RESP)
CFI ET Engaged tone (DLI_ICP_ERR_DEVICE_BUSY)
CFI DT No dial tone (DLI_ICP_ERR_NO_DIALTONE)
CFI NS Number not stored (DLI_ICP_ERR_BAD_MODEM_RESP)
CFI AB Abort Call no carrier (DLI_ICP_ERR_DSR_DOWN)
CFI NT No answer tone (DLI_ICP_ERR_NO_ANSWER)
CFI RT Ring tone or modem does not answer (DLI_ICP_ERR_NO_ANSWER)
CFI CB Local DCE busy (DLI_ICP_ERR_DEVICE_BUSY)
INV Invalid command or configuration (DLI_ICP_ERR_BAD_MODEM_RESP)
CFI Generic call failure (DLI_ICP_ERR_INVALID_RESP)
AT Support
If the modem type option is set to AT, the Autodial Start command causes the
BSC 2780/3780 software to insert the character string “ATE1VD” at the start of the
autodial string. The BSC 2780/3780 software then sends the autodial string to the
modem and waits up to 60 seconds for a response from the modem that signals success
or failure of the call. The BSC 2780/3780 software recognizes the following responses
from the AT modem type:
