SmartHSF Mobile Modem Data Sheet

2.8.2 Blacklist Parameters

The modem can operate in accordance with requirements of individual countries to prevent misuse of the network by limiting

repeated calls to the same number when previous call attempts have failed. Call failure can be detected for reasons such as

no dial tone, number busy, no answer, no ringback detected, voice (rather than modem) detected, and key abort (dial attempt

aborted by user). Actions resulting from such failures can include specification of minimum inter-call delay, extended delay

between calls, and maximum numbers of retries before the number is permanently forbidden ("blacklisted"). Up to 20 such

numbers may be tabulated. The blacklist parameters are programmable. The current blacklisted and delayed numbers can be

queried via AT*B and AT*D commands, respectively.

2.9 DIAGNOSTICS

2.9.1 Commanded Tests

Diagnostics are performed in response to the &T1 command per V.54.

Analog Loopback (&T1 Command). Data from the local DTE is sent to the modem, which loops the data back to the local

DTE.

Last Call Status Report (#UD). This command reports the status of the last call.

2.10 LOW POWER SLEEP MODE

When not connected in data, fax, or speakerphone mode, the HSD is placed in a low power state, i.e., Idle Mode.
