5.11 G.703 Interface
The G.703 Interface supports three different G.703 rates (E3, T3, and STS-1). The physical
interface is a single Female BNC Connector. The data rate for the E3 Interface is 34 Mbps, 44
Mbps for the T3 Interface, and 51 Mbps for the STS-1 Interface. The interface complies with
G.703 electrical specifications.
5.12 HSSI Interface
The HSSI (High-Speed Serial Interface) complies with the HSSI Functional and Electrical
Specifications. The physical interface is a 50 Pin SCSI-2 Type Connector. Electrical levels are
ECL. The pinouts for this interface are listed in Table 5-9.
