Frequently Asked Questions
-
What is a Virtual Tributary 1 (signal)?
-
It is a logical sub-channel defined in SONET/SDH networks that carries lower-rate digital signals encapsulated within higher-rate synchronous frames for flexible grooming and switching.
-
What does SCSI (LVD Ultra160) represent?
-
SCSI (LVD Ultra160) is a parallel SCSI interface using Low Voltage Differential signalling that specifies maximum data transfer bandwidth up to 160 MB/s between a host adapter and SCSI storage devices.
-
Why convert from Virtual Tributary 1 to SCSI (LVD Ultra160)?
-
To compare and translate asynchronous SONET/SDH channel capacities into legacy parallel SCSI storage bandwidth metrics, aiding planning and analysis across network and storage infrastructures.
