-
Actual throughput may differ due to encapsulation and equipment aspects.
-
Virtual Tributary 1 and Fast Ethernet have distinct clocking and framing systems.
Frequently Asked Questions
-
What is Virtual Tributary 1 (signal)?
-
It is a logical sub-channel in SONET/SDH that carries lower-rate digital signals within a synchronous transport frame, allowing independent management of that sub-channel.
-
What does Ethernet (fast) represent?
-
Fast Ethernet refers to IEEE 802.3 standards providing a nominal 100 Mbps data rate, typically used in local-area networks over twisted-pair or fiber cables.
-
Why is this conversion useful?
-
Converting helps translate SONET/SDH transport capacities into equivalent Ethernet speeds for integrating telecom networks with LAN environments.
Key Terminology
-
Virtual Tributary 1 (signal)
-
A logical sub-channel in SONET/SDH carrying a lower-rate plesiochronous digital signal within a synchronous frame, allowing independent grooming and switching.
-
Ethernet (fast)
-
An IEEE 802.3 Ethernet standard family offering a nominal 100 Mbps data rate, typically used in local-area networks over Category 5/5e cables or fiber.
-
SONET/SDH
-
Synchronous optical networking standards that define transport hierarchies and frames for telecom-grade data circulation.
