Ground start is used in PBX environment , it fixes the problem of glare. Digital Signals are of two types: Channel associated signaling (CAS): Signaling information is transmitted using the same bandwidth as the voice. ■ Common channel signaling (CCS): Signaling information is transmitted using a separate, dedicated signaling channel.

A Codec also known as Coding Decoding is a compression mechanism which reduces the bandwidth required for the call. Bandwidth required for a normal PSTN call ==64kbps MoS Mean Opinion score is a Value which tells about the quality of a call. G711 is uncompressed codec. It uses 64 kbps and has the highest MoS. G729 is widely used compressed codec and has a MoS of 3.9.
