Frequently asked questions from XPANDAcell

 

 

Q: What is a Tmedia Gateway?
A: The Tmedia Gateway is a next generation media and VoIP gateway supporting TDM interfaces up to OC-3/STM-1, Transcoding, SS7/C7 termination and "Any to Any" switching. In addition, the Tmedia Gateway is the first to address low power consumption in a high density platform providing more return on investment while aiding the environment.

 


Q: What is a Tdev Gateway?
A: The Tdev Gateway contains all the capabilities of the Tmedia Gateway. In addition, the Tdev gateways allow you to run applications on external servers with carrier grade redundancy options. The Tdev gateways allow up to (16) TMP6400 gateways to act as a single system.
