MP. 0 ] parm__omc_dm_originate_en Originate Enable
This parameter specifies whether this device uses originate or answer data modulation/data protocol procedures.
Range:
1 = TRUE, originate enabled / originate (org) mode
0 = FALSE, originate disable / answer (ans) mode
Default:
0 = FALSE, originate disable / answer (ans) mode
MP. 1 ] parm__dial_billing_delay_duration Billing Delay Timer
This timer specifies the delay from line seizer to the first tone generation.
A value of 0x0 disables this timer.
Range:
0 to 65535, units of 10(mS)
Default: 200 = 2(S)
Conversion:
Billing_Duration = 10(mS) * parm__dial_billing_delay_duration
MP. 2 ] parm__omc_dmdp_max_startup_duration Connect Timer
This timer specifies the maximum time allowed to achieve a successful data connection.
A value of 0x0 disables this timer.
Range: 0-65535, u(Units of 10 ms)
Default: 9000 = 90(S) = 1.5(minute)
Conversion:
Connect_Duration = 10(mS) * parm__omc_dmdp_max_startup_duration
This timer specifies the delay from data modulation connection to the data protocol startup.
Range:
0 to 65535 units of 10(mS)
Default: 3 = 30(mS)
Conversion:
Data_Protocol_Start_Duration = 10(mS) * parm__dp_start_delay
parm__dp_start_delay = Data_Protocol_Start_Duration / 10(mS)
This mask specifies which data protocols will be allowed for the current connection. The inherent order of precedence when all protocols are allowed is as follows:
1st - LAPM
2nd - MNP
3rd - buffered
4th - direct

- The reset default of 0x000F is shown.
- "1" = allowed, "0" = not allowed.
Bitfield Definitions:
Bit 3 "drct" = Enables direct mode. No data protocols are enabled. Direct data flow between data pump V.14 SART and network data FIFOs.
Bit 2 "bffr" = Enables buffered mode. No data protocols are enabled. Direct data flow between data pump V.14 SART and network data FIFOs. However, V.80 modem to modem flow control is supported.
Bit 1 "MNP" = Enables error correction data protocols MNP 1, 2, 3 & 4. This allows the use of MNP 5 data compression.
Bit 0 "LAPM" = Enables error correction data protocol V.42. This allows the use of V.42bis data compression.
In order for this parameter value to take effect for a given connection, it must be set before the Modem connect event is posted/issued.
This mask specifies which data protocols will have precedence outside the inherent precedence.
Note that if a lower precedence is specified that this does not preclude a higher allowed precedence from being used.
