Use the ◄ ► arrow keys to select the parameter to edit, and then use the ▲▼ arrow keys to
select its setting. Press ENTER when done.
5.2.1.10.3 CONFIG: Misc  HSSI
This control setting is applicable only when the Data Interface Type is HSSI.
HSSI handshake control: (2 options)
TA-> CA loop ()
Use the ▲▼ arrow keys to select HSSI handshake control as TA -> CA loop, RR cntl CA, or TA
cntl Tx, and then press ENTER.
5.2.1.10.4 CONFIG: Misc  RTS
This control setting is effective only when the Data Interface is set for RS-422 or
V.35.
RTS/CTS operation: (3 options)
Loop, RTS controls Tx-out ()
Use the ▲▼ arrow keys to set the RTS/CTS control, and then press ENTER. The available choices
are as follows:
Selection Function
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 C TS ar e l ooped s o t hat C TS ec hoes t he s tate of R TS, and R TS
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.
5.2.1.10.5 CONFIG: Misc  Audio-Vol (ADPCM Audio Volumes)
ADPCM Tx1 = +0 dB Tx2 = -2 dB
Volumes: Rx1 = +2 dB Rx2 = -4 dB ()
Use this menu to adjust the gain (or volume) of the audio ESC circuits for both Transmit (Tx) and
Receive (Rx). Use the ◄ ► arrow keys to select the volume to edit, and then use the ▲▼ arrow
