Model 6511RC User Manual 3 • Configuring the Matrix Switch for operation
The Matrix Switch offers two formats for defining DS0 mappings:
• E1 port format—You will identify the 63 E1 signal streams within the STM-1 link using E1 port numbers
1-63. Those with little to moderate experience working with SDH network architecture will most likely
find E1 format to be the simplest and most straightforward method for defining DS0 mappings. Refer to
section “Defining DS0 mappings using E1 port format” on page 64.
• TU format—You will identify an E1 signal stream according to its location within the STM-1 hierarchy,
using the TU-12 number and TUG-2 number within an AUG-3 or within a TUG-3/AUG-4. Experienced
SDH engineers with a clear understanding of STM-1 architecture will most likely prefer to use TU format
to define DS0 mappings. Refer to section “Defining DS0 mappings using TU format” on page 69.
