DESCRIPTION
The PA-2H dual-port HSSI port adapter provides two high-speed serial interfaces. The interfaces on the PA-2H are considered to be data terminal equipment (DTE) devices.
The PA-2H conforms to the BABT/TC/130, EIA/TIA-612, and EIA/TIA-613 standards for HSSI. The PA-2H provides two interfaces. Each interface provides a full-duplex high-speed synchronous serial interface (HSSI) for transmitting and receiving data at rates of up to 52 megabits per second (Mbps). The HSSI, which has been standardized as EIA/TIA 612/613, provides access to services at T3 (45 Mbps), E3 (34 Mbps), and Synchronous Optical Network (SONET) STS-1 (51.82 Mbps) rates. The actual rate of the interface depends on the external DSU and the type of service to which it is connected. Each HSSI port on the PA-2H is a female 50-pin SCSI-II-type receptacle. You must use an HSSI interface cable from Cisco Systems to connect the interface to an external data service unit (DSU).
