in the Remote Office. (This interface is a dual routed port.)
■ An IP router that is capable of supporting both interior and exterior gateway
routing protocols (RIP V2 and OSPF).
■ A Voice Over IP (VOIP) gateway to convert TDM-based audio streams (from DCP
and analog phone sets or incoming digital and analog trunks) into IP-based streams
for transport to/from the main DEFINITY site, or other IP-connected DEFINITY
remote sites and/or IP phones and IP softphones.
■ Support for CODECs including G.711 (A-law and U-law), G.729, and G.723

signalling. The International E1 interface is capable of supporting up to thirty, 64
Kbps bearer channels.
