Functional Description
The MRC module is a daughter card installed on top of the MCB Office card. The
MRC module provides media channels used to convert digital media streams into IP
Packets and vice versa, thereby converting standard Coral “talk” into Internet Protocol
“talk”. Media channels are also used when one of the calling parties is not an IP host.
No media channels are needed for pure IP-to-IP connections (direct-connects). See
Figure 8-12 for an illustration of IP-to-IP connections versus non IP-to-IP connections
in the Coral. Each Coral IPx Office main unit may be equipped with one MRC module.
