 The
ESN310 is a full-featured Layer2 Fast Ethernet switch with built-in
Power over Ethernet (PoE). It is ideal for concentrating IP telephony
and data traffic for Converged Enterprises with MD110, MX-ONE, Business
Phone and MD Evolution. Dialog 4000 IP terminals are powered directly
from the ESN310, thus elliminating the need for separate power supplies
for IP phones. The ESN310 integrates seamlessly into the existing IT
infrastructure to offer an end- to- end solution for your corporate
IP telephony and data needs.

ESN310 has 24 tributary (downlink) ports of the 10/100 Mbps Fast Ethernet
type and two aggregate (uplink) ports of the 10/100/1000 Mbps Ethernet
type. It has built-in Power over Ethernet (PoE) functionality for power
distribution to the connected our Dialog 4000 IP terminals, via the
downlink Ethernet ports. ESN310 is designed for 19” rack mounting.

| 802.1p based CoS is supported, enabling
Priority queues to be used to guarantee the Quality of Service (QoS)
needed for delay-sensitive applications like IP telephony or video conferencing.
Each packet going through the switch can be assigned a queue priority,
allowing delay sensitive traffic to pass through the switch first (strict
scheduling or WRR). |

By use of the VLAN technology, it
is possible to create separate logical networks within the Ethernet
LAN. In this solution, VLAN is used to separate traffic types or different
services and to improve security. Up to 256 different VLANs can be defined
in the ESN310. |

| |
ESN310 supports the use of IGMP snooping
(IGMP; the Internet Group Management Protocol). The switch listens to
IGMP messages to build a mapping table and associate forwarding filters.
It dynamically configures the switch ports to forward IP multicast traffic
only to those ports associated with multicast hosts. |

ESN310 is SMNPV2c compliant for alarms
and traps towards SMNP clients such as HP OpenView. For configuration
management, the ESN310 can be managed through an RS-232C console port
or via any of the Ethernet ports via telnet or SSH sessions. IP address/management
VLAN allocation, as well as, authentification control can be enabled
via the local RC232 port to authorise/manage remote access. |
