2.11 CALLER ID
Caller ID can be enabled/disabled using the +VCID command. When enabled, caller ID information (date, time, caller code, and name) can be passed to the DTE in formatted or unformatted form. Inquiry support allows the current caller ID mode and mode capabilities of the modem to be retrieved from the modem.

2.12.1 Programmable Parameters
The following parameters are programmable:
∙Dial tone detection levels and frequency ranges.
∙DTMF dialing transmit output level, DTMF signal duration, and DTMF interdigit interval parameters.
∙Pulse dialing parameters such as make/break times, set/clear times, and dial codes.
∙Ring detection frequency range.
∙Blind dialing disable/enable.
∙The maximum, minimum, and default carrier transmit level values.
∙Calling tone, generated in accordance with V.25, may also be disabled.
∙Call progress frequency and tone cadence for busy, ringback, congested, dial tone 1, and dial tone 2.
∙Answer tone detection period.
∙
2.12.2 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
2.13 DIAGNOSTICS
2.13.1 Commanded Tests
Diagnostics are performed in response to &T commands 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.
Analog Loopback with Self Test (&T8 Command). An internally generated test pattern of alternating 1s and 0s (reversals) is sent to the modem. An error detector within the modem checks for errors in the string of reversals.
Remote Digital Loopback (RDL) (&T6 Command). Data from the local DTE is sent to the remote modem which loops the data back to the local DTE.
Remote Digital Loopback with Self Test (&T7 Command). An internally generated pattern is sent from the local modem to the remote modem, which loops the data back to the local modem.
Local Digital Loopback (&T3 Command). When local digital loop is requested by the local DTE, two data paths are set up in the local modem. Data from the local DTE is looped back to the local DTE (path 1) and data received from the remote modem is looped back to the remote modem (path 2).
2.13.2 Power On Reset Tests
Upon power on, an MDP test is performed. If the MDP is not operational, an error indication is generated.
2.14 LOW POWER SLEEP MODE
When not being used, the MDP is placed in a low power state.
