Ear and Mouth with 4 port network interface module was acceptable only with some countries?
How many ports used for calls and what about signaling? Is it similar to ISDN BRI?
If E & M port is inserted with voice gateway what is the dependency of DSP? What is recommended PVDM module?
How it process the calls with other location where E1 controller is deployed?
Any one implemented in multiple locations can share the sample configuration?
