communications A DS level and framing specification for synchronous digital streams, over circuits in the North American digital transmission hierarchy, at the T1 transmission rate of 1,544,000 bits per second (baud). DS1 is commonly used to multiplex 24 DS0 channels. Each DS0 channel, originally a digitised voice-grade telephone signal, carries 8000 bytes per second (64,000 […]
- Ds1c
communications A DS level and framing specification for digital signals in the North American digital transmission hierarchy. A DS1C signal uses 48 PCM channels and has a transmission rate of 3.15 Megabits per second, twice that of DS1. DS1C uses two DS1 signals combined and sent on a 3.152 megabit per second carrier which allows […]
