5.1.3 FastE
The ETS2 supports FastE electrical interfaces. The customer cables are terminated on the rear of the shelf
using high-density 50-pin connectors for each direction of transmission. Refer to Table 5-3 for electrical
specifications for these inputs.
5.2 Synchronization Interface
The TE-2020 system supports synchronization from three source types:
• SONET interfaces
• BITS inputs
• Internal oscillator
The TE-2020 offers up to 6 user-selectable timing reference designations. Any SONET interface or each of
two available BITS inputs may be designated as the primary or secondary source. Two external clock out-
puts are also supported. The TE-2020 also contains a Stratum-3 internal oscillator source. Refer to Table 5-
2 for BITS input specifications. Diagram of the pins is also shown in Figure 5-1
Connection 64-pin Amp Champ
