What is a Trunk Gateway

What is a Trunk Gateway

The
trunk gateway is an important part of the NGN solution. It is located at the
edge access layer of the NGN network and connects the PSTN and NGN networks to
realize the function of IP packet to TDM. It carries the voice tandem task
between the IP domain and the circuit domain, and requires a good processing
mechanism for the echo on the circuit side. The functions of the trunk gateway
include: voice processing, call processing and control, maintenance and
management, etc.
