Calls are answered based on the POTS Answer settings in Config 1 & 2. Adjustments to
these Config settings are not normally necessary when connecting between Tieline codecs.
They are usually adjusted when connecting to non-Tieline codecs over POTS (see
POTS Answering
5. Click the Max Bitrate drop-down arrow to adjust the maximum bit rate (dialing and answering).
The default setting is 28800 (28.8kbps) and this only affects POTS Codec calls. The range of
the setting is 9.6kbps to 33.6kbps. Even if the line is capable of establishing a connection at a
higher bit rate, the Max Bitrate setting is the highest bit rate that will be attempted. Reducing
this value can improve connection reliability on poor quality lines. If two codecs are not
configured with the same setting, they will attempt to connect at the lowest of the two Max Bit
rate settings.
Important Note: G5 POTS modems initially attempt to establish a link at the lowest
Max Bitrate setting configured in the two modules being connected. If the POTS line
doesn't support this bit rate, the modems will attempt to connect at the highest possible
bit rate to suit the prevailing line quality at each end of the link.
6. Click the drop-down arrow for Dialing Method to select Tone (DTMF) or Pulse dialing over
POTS Codec connections. Tone dialing is used always when the Answer Mode is Analog
Phone.
7. Click the drop-down arrow for Dial Tone Detect to select either:
·
Wait for Dial Tone: The module will only be allowed to dial when a dial tone is present
on the line.
·
Blind Dialing: Allows the module to dial when no dial tone is present.
