DCS Primer Types of Digital Cross-connect Systems
N-DCS or 1/0 DCS
- DS1, DS0 interfaces
- Cross-connects at DS0 level
- Provides DS0 test access
W-DCS or 3/1 DCS
- 3/1 DCS cross-connects at DS1 level and provides DS3 muxing and termination
- A SONET W-DCS cross-connects at VT1.5 and provides SONET signal muxing and termination
B-DCS or 3/3 DCS
- Interfaces with a combination of SONET signals and DS3 and cross-connects at DS3, STS-1, or higher
- A SONET BDCS cross-connects at STS-1 and provides SONET signal muxing and termination
- A 3/3 DCS cross-connects at DS3 level
