The functions of MG-SDH digital single-core can be expanded through software upgrades.

Question

Options

• ATrue
• BFalse

• A
  14% (4)
• B
  86% (24)

Explanation

Option B is correct because the MG-SDH digital single-core is a hardware-defined platform - its functional capacity is fixed at the hardware level by its physical chip and circuit design, meaning software upgrades alone cannot expand its core capabilities. Unlike software-defined or modular SDH platforms that support feature licensing or firmware-level function expansion, the single-core variant has a rigid, non-extensible architecture. This means adding new functions requires a hardware replacement or upgrade to a more capable platform, not just a software patch or license key. Option A is incorrect because it assumes the single-core behaves like a software-configurable system, conflating software configuration (which is possible) with functional expansion (which is not).

Memory tip: Think of the single-core as a fixed-function ASIC - just as you can't turn a basic calculator into a smartphone with a software update, you can't expand a single-core SDH unit's functions through software alone. "Single-core = single set of functions."
