Quick Negotiation Enable: Old POTS Module Only
When this box is checked the modem will attempt to connect at the highest bit-
rate automatically. If this box is not checked the modem will attempt to connect
initially at 19,200 bps and then negotiate the highest bit-rate.
Very Important Notes:
Quick Negotiation Enable
is not necessary with the new POTS G3 module and it
has been removed from the POTS G3 module menus. It is still visible in
Tool
Box
software but has no impact if you are using a POTS G3 module.
In addition, the
Auto
and
Up
options have been removed from the
Reneg (Fast)
POTS G3 module menus.

Dial Method
This pull-down menu selects either
Tone
(DTMF) dialling or
Pulse
dialling.
25.12.
Leased Line
This option needs to be checked for operation over leased 2-wire bi-directional
lines. As the codec modems require a loop voltage source for correct operation,
an optional line interface unit is available for use with dedicated 2-wire circuits
where the loop voltage is not present.
Important note on operating in Leased Line mode:
When leased line mode is enabled the dial tone and progress tones are disabled.
In this mode it is necessary to manually answer the call at the remote codec
initially. If you want the remote codec to automatically re-answer after losing a
connection, you should enable
Auto Reconnect
on both the remote and local
codecs. Then if you lose a connection for some reason, after you have already
made a successful call, the codec should auto-reconnect.
To enable
Auto Reconnect
using the codec menus, press
SOFTKEY 4 Menu
,
then select [Configuration] > [Auto Reconnect] > [Enable]. The
Auto Reconnect
function will now be enabled.
If
Auto reconnect
is enabled in the codec menu or via
Tool
Box
software, it will
attempt to redial indefinitely in the manual default profiles. If you wish to adjust
the redial setting in the codec to only dial a certain amount of times, you will
need to use the
Automatic Redial
function in
Tool
Box
software. Do not enable
both the
Automatic redial
and the
Auto reconnect
functions at the same time as
they will conflict with each other. For more information please see the sections
on
Automatic Redial
and
Auto reconnect
in this manual.
