Recommendation
When possible we recommend that you use the same pair of modules when
connecting between two codecs. This is not always possible, so please note
the following differences in dialing with different module combinations.
10.11.2.
POTS G3 Module Dialing Screen
The new POTS G3 module dials a little differently to the original POTS
module. The dialing process explained in this section will occur when dialing
from a POTS G3 module to a POTS module, or a new POTS G3 module.
When dialing is initiated from the codec the screen displays as shown in the
following image.
Figure 21: New POTS G3 Module Connecting
The codec dials out and displays a countdown timer and the word
‘Connecting’ until a call has been established and retraining and
renegotiation has been completed. Once this process is completed the
standard connection screen is displayed.
Figure 22: Standard POTS Connection Screen
This is a little different to dialing with the original
T
ieline
POTS module.
When dialing with this module the codec displays intermediate connection
states such as answering,
negotiating and stabilizing in real-
time for each connection, as well
as
Rx
and
Tx
numbers - as shown
in the right-hand image.
Very Important Notes:
Quick Negotiation is not necessary with the new POTS G3 module and it has
been removed from the POTS G3 module menus.
In addition, the
Auto
and
Up
options have been removed from the
Reneg
(Fast)
POTS G3 module menus.

Dialing from a POTS G3 Module to a POTS Module
When dialing from the new POTS G3 module to an old POTS module, the
codec will attempt to connect initially at 19,200 bps. If line quality is above
