Applications
DS1 Distribution
DS1 Pipes
The SLC-2000 System can be configured to support up to 28 DS1 pipes without
using an external multiplexer. In a DS1 only configuration no MDS are provided
and the DS1 pipes can be used to support DS1 service or DS1 interfaces for
collocated
SLC Series 5 or SLC 96 systems. This configuration is used for those
applications that initially require up to 28 DS1s and anticipate future DS0 services.
Whenever DS0 services are needed MDS assemblies can be added.
DS1 Extensions
The DDM-Plus system provides both metallic and optical DS1 extensions. For
metallic applications the DDM-Plus can be used as a repeater shelf for T1
extensions. For optical applications the DDM-Plus provides multiplexed optical
transport of four DS1 pipes on multimode or single mode fiber.
