Presumably the teleswitching is a little like "slow Morse" in nature, requiring little bandwidth and power to be effective. It might be that dispensing with the pesky speech modulation bit and leaving a whisper of carrier for teleswitching and legacy 198kHz-referenced devices could carry on for a few years hence at somewhat lower cost until all dependent devices are out of service, or a big sender/mast maintenance problem comes up and the plug gets finally pulled.
