HSSI Handshake Control
HSSI handshake control: (2 options)
TA-> CA loop (
v
)
Note:
This control setting is only applicable is the data interface type is HSSI.
Using the

RTS/CTS Control
RTS/CTS operation: (3 options)
Loop, RTS controls Tx-out (
v
)
Note:
This control setting is effective only if the data interface is set for
RS-422
or
V.35
.
Edit the RTS/CTS control using the
▲ ▼
arrow keys, then press
ENTER
. The possible options
are as follows:
RTS/CTS Loop, No Action
RTS and CTS are looped, so that CTS echoes the state of RTS, but RTS
does not control the ON/OFF state of the carrier.
Loop, RTS controls Tx out
RTS and CTS are looped, so that CTS echoes the state of RTS, and RTS
controls the ON/OFF state of the carrier (i.e., the modem will not bring up
its TX carrier until RTS is asserted).
RxEnable
RTS is ignored, and CTS is asserted unconditionally.

ADPCM Audio Volumes
ADPCM Tx1 = +0 dB Tx2 = -2 dB
Volumes: Rx1 = +2 dB Rx2 = -4 dB (
34v
)
This menu permits the gain (or volume) of the audio ESC circuits of both Receive and Transmit
to be varied. The permitted range of the volumes is –6 to +8 dB, in 2 dB steps.
Select the volume to edit using the
