Switch – PSTN Telephony Switch

PSTN Switches were originally introduced to improve efficiency of the telephony network and negate the requirement for every telephone in the network to be directly connected through dedicated connections. They enable the establishment and termination of voice calls to be enabled with networks external to the PSTN, e.g. in mobile networks the PSTN Switch will connect to the GMSC.
