FUNCTION
Unused.
Should be set = 0 for proper operation.
Monitor Mode 2.
Sets the internal linear gain boost (dB) for monitor
mode applications. Please refer to the table below for proper settings.
Monitor Mode 1.
Sets the internal linear gain boost (dB) for monitor
mode applications. Please refer to the table below for proper settings.
Monitor Mode 0.
Sets the internal linear gain boost (dB) for monitor
mode applications. Please refer to the table below for proper settings.
1:1.36 Transformer Select
0 = 1:2 transmit transformer
1 = 1:1.36 or 1:1.6 transmit transformer (see table below for details)
Analog Loopback.
Setting this bit internally connects TTIP and TRING to
RTIP and RRING. The external signal at the RTIP and RRING pins is
ignored.
Unused.
Should be set = 0 for proper operation.
Transmit G.703.
This control bit works with CCR5.5 to select G.703
functionality on the transmitter and receiver (
Table 8-2
). These bits
determine whether the line receiver and transmitter should receive/
transmit a normal E1 signal (Section 6 of G.703) or a 2.048MHz
synchronization signal (Section 10 of G.703).
