Ater Interface

In the Ater-interface, speech transcoders are moved from the BSC:s to the MSC, unlike in the more common A-interface where the transcoders remain in the BSC:s.

The advantages of the Ater interface are:

• The transcoder units can be more efficiently used
• More speech channels  can be transmitted on the available connection between the BSC and the MSC, because the un-coded speech takes up less bandwidth (16kbit/s channels instead of 64 kbit/s all the way to the MSC)

Solver is able to simulate most of the common bit rate formats between the BSC and the transcoders in the MSC. More bit rates can be added upon customer requests.
