Which of the following statements about MS-OTN are correct?

The correct answers areA, B, and C. Here’s a detailed explanation of each statement:

A. MS-OTN is short for Multi-Service Optical Transport Network:This is correct.MS-OTNintegrates multiple technologies (e.g., OTN, SDH, Ethernet) into a single platform, enabling converged transport for diverse services.

B. MS-OTN supports SDH, PKT, and OTN services:This is correct. MS-OTN supportsSDH (Synchronous Digital Hierarchy)for legacy services,PKT (Packet)for Ethernet-based traffic, andOTN (Optical Transport Network)for high-capacity transport.

C. MS-OTN supports ODUk cross-connections:This is correct. MS-OTN leveragesODUk (Optical Channel Data Unit-k)cross-connections to efficiently switch and route traffic at the optical layer, ensuring high performance and scalability.

D. OSN 1800V, 1800II E, and 1800I E all can support MS-OTN:This is incorrect. While theOSN 1800Vand1800II Esupport MS-OTN, the1800I Eis a simpler device designed for access networks and does not fully support MS-OTN capabilities.
