ShoreGear™ Voice Switches
ShoreGear voice switches are highly reliable devices because they use flash memory for storing information rather than a mechanical hard disk, which can be prone to failure. In addition, since the switches use VxWorks, the leading embedded, real time operating system from Wind River Systems, ShoreTel IP telephony systems are not subject to the numerous attacks and viruses associated with server-based solutions. With embedded call control, you have confidence since dial tone is being delivered by the most reliable, robust platform on the market.
Call control on the ShoreTel system is distributed to every ShoreGear voice switch on the network, eliminating any single point of failure. In the unlikely event a ShoreGear voice switch fails or becomes isolated by a network fault, the other switches on the network continue to operate without being affected, picking up the load to compensate for the affected switch.
If a ShoreGear voice switch supporting IP phones fails or is isolated by a network fault, the phones automatically fail over to another voice switch, providing complete redundancy. Also, since call control is distributed, redundancy is delivered cost effectively with N+1 rather than Nx2 configuration required by centralized systems. Second, third, and fourth level redundancy can be configured by simply adding more voice switches.
If a ShoreGear voice switch connected to the PSTN fails or is isolated by a network fault, the system will automatically route calls out an alternative switch.
If the wide area network is down, or if admission control for voice traffic on the wide area network is reached, extension to extension calls between sites automatically route over the PSTN ensuring seamless communication.
ShoreGear voice switches feature redundant network uplinks. If the upstream network device fails, the ShoreGear voice switch will automatically failover to the redundant link ensuring continuous operation.
The ShoreGear-120, 90, 60, 50 and 40 voice switches all feature power fail transfer. In the event of a complete power outage that exceeds the duration of your reserve power, one analog trunk on the voice switch will automatically connect to one analog telephone, providing you with emergency dial tone.
