Extreme Networks Offers Switches for IP Telephony

Extreme Networks introduced a new family of Layer 3 fixed Gigabit Ethernet switches designed for IP telephony, wireless and converged applications. The new Summit 400-24 family of switches delivers chassis-like availability with new "UniStack" stacking technology that incorporates Link Layer Discovery Protocol (LLDP) for simplifying device discovery and Extreme's "AccessAdapt" technologies to deliver native wireless LAN and IP telephony support.

The UniStack technology allows for up to eight Summit switches to be managed as one device, with throughput of 40 Gbps per switch. To further simplify configuration and management, Extreme Networks is now offering LLDP with its switches to automate the discovery of IP telephony devices, wireless access points and other Ethernet switches. This simplifies troubleshooting while allowing Extreme Networks' EPICenter management suite to discover and maintain accurate network topologies in multi-vendor environments.

The Summit 400-24p features Power over Ethernet (PoE) delivering 15.4 watts of power to every port along with optional redundant power supplies featuring instantaneous power fail-over that is transparent to users.

Extreme Networks is furthering support for its UAA wireless solution by extending its AccessAdapt technology to the Summit 400-24 switches. AccessAdapt allows the Altitude thin Access Points (APs) to automatically gain its identity and configuration characteristics from the Ethernet port. To enhance security, once unplugged, the AP does not store any critical network data.

The company said IP telephony applications running on the Summit 400 switches are enhanced with policy management capabilities including end-to-end QoS for prioritizing applications. Network authentication capabilities provide consistent security, over wired and wireless, for every individual and a diverse range of networked devices.

The new Summit 400-24 switch family supports Layer 3 routing capabilities including OSPF, VRRP and ESRP. Summit switches also come with standard support for Extreme Networks' Ethernet Automatic Protection Switching (EAPS), which delivers sub-50 millisecond service recovery should physical network connections be cut or interrupted.

The new Summit 400-24p and Summit 400-24t switches are available in April. Pricing begins at $4,495.00.
