call gapping การใช้

For people around the country who heard the message " All circuits are busy, " call gapping was a likely cause.
In industry terms, the strategy is called " call gapping, " and it was employed with a few keystrokes by network managers at the control center.
This provided the call gapping control that stopped exchanges being overloaded by too many incoming calls ( an example being when newspaper competitions misprinted winning numbers or too many people calling Regent's Park Mosque during the start of Ramadan-both a frequent occurrence at North Paddington Exchange before it was modified to TXE4E ).
