HOW DOES PRODYS IP FAMILY OF CODECS WORK?
Given the different nature of the three communication standards that the Prodys
IP Family codec supports, the device requires network specific settings for
matching the transmission media. What is more, in situations, Prodys IP Family
codec is capable of dealing with two independent communications at the same
time. This chapter is a practical guide to help in understanding just how the
Prodys IP Family codec unit works under different configurations, in particular
the non conventional ones.
V.1
Selecting the network interface
Firstly, when we refer to the ‘network interface’ we are always referring to the
communications port that is used for the transmission of ‘audio data’. The
NET
option from the top menu is applicable for this selection. There are three
settings available for the Prodys IP Family codec:
Prodys IP Family codec operating as “
IP CODEC
”: The codec will be
configured to establish communications via the Ethernet port using the
IP protocol.
Prodys IP Family codec operating as “
ISDN CODEC
”: The codec will be
configured to establish communications via a basic access ISDN
connection. The Prodys IP Family codec has a multi-protocol ISDN
terminal socket ready for connection to a basic rate 2B+D interface.
Prodys IP Family codec operating as “
X21 CODEC
”: The codec can be
configured to establish communications via dedicated digital lines at
64, 128, 192, 256, 384 and 576 Kbps.
