Note:
Disconnect supervision (DS) it’s required to disconnect the telephone lines when some one hang-up the lines so its doesn’t hold the lines for longer time and doesn’t release the lines and by this way the line will not be available for use. It’s very important to use DS system with DS software if the customer utilizing voice mail. If not then the system will encounter a lot of messages with hang-up tones due to non release of the CO –line after the customer hang-up.with DS cabinets the system will send the DS signal to the central office (if its equipped) to notify when the lines was drooped in order to release the line and make available right away.
