MP.29 ] parm__vpcm_max_power V.PCM Maximium Transmit Power

This parameter specifies the maximum transmit power for the V.PCM modulation.

Range: ?
Default: 12

MP.30 ] parm__vpcm_reference_point V.PCM Transmit Power Reference Point

This parameter specifies the measurement reference point for transmit power.

Range: ?
Default: 0
V.PCM Reference Point Parm Rev. 981030
The following V.PCM reference point parameter value has the indicated initial setting:
parm__vpcm_reference_point = 0x0001 = 1
This sets the power reference point at the Telco line card. This allows attenuation pads to be taken into account.

MP.31 ] parm__k56_rbs_max Modulation k56flex Server Limit

TBD

MP.32 ] parm__k56flex_tx_data_rate_max k56flex Modulation TX Maximum Rate

This parameter specifies the allowed maximum transmit rate for the k56flex modulation.

Range: 1-15 corresponds linearly to rates 32000 bps - 60000 bps
Default: 8

MP.33 ] parm__k56flex_tx_data_rate_min k56flex Modulation TX Minimum Rate

This parameter specifies the allowed minimum transmit rate for the k56flex modulation.

Range: 1-15 corresponds linearly to rates 32000 bps - 60000 bps
Default: 1

MP.34 ] parm__dteif_big_endian DTE Big Endian Enable

This parameter specifies the network FIFO data alignment. Each FIFO location is a 16-bit word containing 2 8-bit characters. This parameter specifies the alignment of the 2 character.

Big Endian =

LR ( least recent ) character 1st; bit locations 15 to 8

MR ( most recent ) character 2nd; bit locations 7 to 0
Little Endian =

MR ( most recent ) character 1st; bit locations 15 to 8

LR ( least recent ) character second; bit locations 7 to 0.
Example: Given the character string "ADSP-mod870", the alignments would be as follows:

Big Endian		Little Endian

A	D	S	A
S	P	P	D
-	m	m	-
o	d	d	o
8	7	7	8
0			0

MP.35 ] parm__ppp_rx_mode_en PPP Rx Manual Enable

This parameter allows the PPP receive mechanism to be enabled manually by setting this parameter.

Range: TRUE, FALSE
Default: FALSE

MP.36 ] parm__ppp_tx_mode_en PPP Tx Manual Enable

This parameter allows the PPP transmit mechanism to be enabled manually by setting this parameter.

Range: TRUE, FALSE
Default: FALSE

MP.37 ] parm__fp_ppp_detect_en PPP Detect Mode Enable

This parameter allows the detection of PPP framing protocol by detecting a sequence of characters representing the start of a PPP frame. PPP is enabled separately in the transmit and receive direction. parm__fp_ppp_detect_en is used to enable detection. If this parameter is not enabled the DSP will be in transparent mode forever. This parameter can be turned on at any time. Once PPP is deteected on transmit and receive turning off the PPP detect parameter will not disable PPP. Note, the detection phase is conditionally compiled using DO_CFG_PPP_DETECT; otherwise, see section 4.2 for manually enabling PPP.

Range: TRUE, FALSE
Default: TRUE
PPP Auto Detect Parm Rev. 981030
The following PPP auto detect parameter value has the indicated initial setting:
parm__vpcm_reference_point = 0x0000 = 0
This disables the PPP auto detect feature.

MP.38 ] parm__fp_ppp_rx_accm Rx Async-Control-Character-Map

The Async-Control-Character-Map by default is 32 bits in size corresponding to all characters less than 0x20. Any character received that is flagged in this map is discarded. The receive ACCM is set to the default 0xffffffff on a new connection. After a connection, the receive ACCM may be negotiated. The receive ACCM can be changed by modifying this parameter.

Range:
Default: 0xffffffff

MP.39 ] parm__fp_ppp_tx_accm Tx Async-Control-Character-Map

The Async-Control-Character-Map by default is 32 bits in size corresponding to all characters less than 0x20. The transmit ACCM is set to the default 0xffffffff on a new connection. After a connection, the transmit ACCM may be negotiated. The transmit ACCM can be changed by modifying this parameter.

Range:
Default: 0xffffffff

MP.40 ] parm__report_event_mask Event Filtering

This parameter specifies the level of event reporting by the Modem. This parameters allows control over the flow of reported events from the Modem to the Host.

There are 2 allowed settings. The default setting reports an extended set of events. This setting is useful for debug purposes. The other setting reports a reduced set of events. This setting should be chosen for optimal performance.
The Modem uses the following criteria to determine if an event is reported:
if ( Event_Number & 0x3000 & parm__report_event_mask )

report( Event_Number ) ;

Range:

Debug parm__report_event_mask = 0x3000

Optimal parm__report_event_mask = 0x1000
Default = 0x3000

MP.41 ] parm__report_status_mask Status Code Event Filtering

This parameter specifies the level of status code event reporting by the Modem. This parameters allows control over the flow of reported status code events from the Modem to the Host.

There are 2 allowed settings. The default setting reports an extended set of status code events. This setting is useful for debug purposes. The other setting reports a reduced set of events. This setting should be chosen for optimal performance.
The Modem uses the following criteria to determine if a status code event is reported:
if ( Status_Code_Event_Number & 0x5000 & parm__report_status_mask )

report( Status_Code_Event_Number ) ;

Range:

Debug parm__report_status_mask = 0x5000

Optimal parm__report_status_mask = 0x1000
Default = 0x5000

MP.42 ] parm__tel_answer_tone_length Answer Tone Length

This parameter specifies the Modem's answer tone length.

Range:

1 to 65535 units of 1(mS)

Derivation:

parm__tel_answer_tone_length = Answer_Tone_Length / 1(mS)
Default:

parm__tel_answer_tone_length = 5000 = 5(S)

MP.43 ] parm__dm_v90_dpcm_data_rate_mask V.90 Data Rate Mask

This parameter is used to enable the use of particular Tx data rates for the V.90 modulation family. The range of rates is the following:
