Connecting to Legacy POTS Modules in G3 Codecs
These modules have slightly different characteristics when connecting. When dialing from a G5
POTS module to these older POTS modules the codecs will attempt to connect initially at
19.2kbps. If line quality is above 80% at this bit rate then the codec will 'retrain' the connection
up to a maximum of 28,800bps (depending on modem handshaking). The codec will then
renegotiate the link downwards to the highest possible bit rate where line quality is greater than
70%.
How to Configure ViA POTS G5 Codec Connections
To configure the codec to dial using POTS for the first time:
1. Ensure that the correct country setting is configured in your codec via Home screen >
System > Country. This ensures the correct settings are used by the codec when making
POTS connections.
2. When dialing between two Tieline codecs use the Dialer
program.
Other more advanced settings can also be configured:
1. Select Home screen > Settings
POTS module settings specific to your codec site.

2. If you are connecting to non-Tieline codecs you may need to create an answering "Config",
which determines the settings used when answering a non-Tieline POTS call:

Important Note: The phone input is used to Monitor Modem Tones (default setting On)
and for monitoring and adjusting audio in Analog Phone mode (default is POTS Codec
mode). These settings are configured via Settings

Making Analog Phone (Voice) Calls
The ViA POTS G5 module is capable of making analog voice calls. This may be useful to dial a
telephone hybrid, or to use for communications, or when there is no Tieline codec at the other end of
the link. Remember analog voice calls are only 3 kHz audio quality. To configure analog phone
answering mode navigate to Settings
Mode > Analog phone.
