What is silence suppression? To help understand silence suppression technology, consider this example: Some people talk all the time. Even they have to take a breath and they sometimes listen and are quiet. On a phone call, it is quite common that there is silence in one direction of the call while there is speech carried in the other direction. The public switched telephone network ( PSTN ) does not take advantage of this condition. The PSTN opens up a path in both directions, between the speakers, and allocates 100% of the path capacity to the call, even when there is silence. IP networks operate differently. Packets are transmitted when there is data and control information. Packets are not sent when there is nothing to send. In essence, when there is data silence, no IP network bandwidth is consumed. Silence suppression, also called voice activity detection voice activation detection
Voice Compression (DCME): It will be present between two MSCs, Telco Switches or International Trucking Gateways to compress up to 8 E1 voice traffic voice channels to a single E1 link.
What is LCF? ABIS local connectivity feature (LCF) LCF will be introduced across Ericsson's base-station portfolio, and is scheduled for commercial release in mid-2008. The solution allows local calls originating and terminating at the same base station, or cluster of base stations, to be switched locally in the Ericsson GSM radio network. This reduces operators' transmission costs because there is no need for the backhaul network that traditionally carries mobile voice and data traffic from radio base stations to the nearest switching node. This solution will help bridge the digital divide and bring telecommunications to locations that currently lack mobile coverage
