Parameter Description
seconds.
 A special CAS table can be used to report call status events
(Active/Idle) to the PSTN side during Cut Through mode.
 This feature can also be configured in a Tel Profile and therefore,
assigned to specific B-channels that use specific CAS tables.
58.10.5.8 TTY/TDD Parameters
The TTY (telephone typewriter) or telecommunications device for the deaf (TDD) is an
electronic device for text communication via a telephone line for those with impaired
hearing. The TTY/TDD parameters are described in the table below.
Table 58-52: TTY Parameters
Parameter Description
[TTYTransportType]
Defines the device's transferring method of TTY signals during a
call.
 [0] = (Default) Disable.
 [1] = Bypass - entering HBR on TTY tone detection. The HBR
coder is selected by the FaxModemBypassCoderType
parameter. The network packets that are generated and
received during the bypass period are regular voice RTP
packets (per the selected bypass coder), but with a different
RTP payload type (103). You can change this payload type by
using the ModemBypassPayloadType parameter. When TTY
signal transmission ends, reverse switching from bypass coder
to regular voice coder is performed.
 [2] = Relay (signals sent over the EVRC/B or AMR codec) -
TTY
phone device transfer using In-Band Relay mode for TTY signal
transport. The following TTY relay standards are supported:

3GPP2 C.S0014-0-3 and 3GPP2C.s0028-0 v2.0 over
EVRC and EVRC/B.

Text over Cellular Text Modem (CTM) over an existing
speech path when using AMR or GSM EFR coders.
Note: To support TTY Relay (2), you must configure the device to
use the EVRC/B, AMR, or GSM EFR coder.
58.10.5.9 Character Conversion Parameters
The Character Conversion table parameter is described in the table below.
Table 58-53: Char Conversion Table Parameters
Char Conversion Table
Char Conversion
[CharConversion]
Defines Unicode-to-ASCII character conversion rules. The format of the
ini file table parameter is as follows:
[CharConversion]
FORMAT CharConversion_Index = CharConversion_CharName,
CharConversion_FirstByte, CharConversion_SecondByte,
CharConversion_ConvertedOutput;
