Dialogic Corporation
1.26.1 Feature Description
The FSK transmit (FM_ParmFSKTxSignalLevel) and receive
(FM_ParmFSKRxSignalLevel) signal level parameters are described below.
FSK Transmit and Receive Signal Level
Number: 0x2a (0x2a04 for transmit) (0x2a00 for receive)
Description: Two-way Frequency Shift Keying (FSK) and ETSI FSK allow the exchange
of small amounts of data between a telephone and the server using FSK as the transport
layer. The two-way FSK functionality allows products to transmit and receive half-duplex
FSK Bell 202 1200 bps data over the Public Switched Telephone Network (PSTN). ETSI
FSK functionality is based on the specification ETSI 201 912.
The Transmit and Receive Signal Level parameters allow you to adjust the signal level of
both the transmit and receive FSK signal levels.
Values:
• -50 to -5 dbm for FSK transmit signal level, -14 dbm (default)
• -60 to -5 dbm for FSK receive signal level, -46 dbm (default)
Guidelines for FSK Transmit: To set the signal level of the FSK transmit signal to other
than the default value of -14 dbm, you must edit the applicable CONFIG file.
Example: To set the FSK transmit signal level to a value of -20 dbm, you need to add a
new section [0x2a] at the end of the CONFIG file and include the FSK Transmit Signal
Level parameter in that section as follows (shown in bold):
[0x2a]
SetParm=0x2a04,-20 !FM_ParmFSKTxSignalLevel
Guidelines for FSK Receive: To set the signal level of the FSK receive signal to other
than the default value of -46 dbm, you need to edit the CONFIG file by adding the FSK
Receive Signal parameter to the new [0x2a] section.
Example: To set the receive signal level to a value of -15 dbm, add the line shown in bold
to the new section you created for the FSK Transmit Signal Level parameter:
[0x2a]
SetParm=0x2a04,-20 !FM_ParmFSKTxSignalLevel
SetParm=0x2a00,-15 !FM_ParmFSKRxSignalLevel
