10/100/1000 Ethernet extenders allow you to extend Ethernet services beyond the general IEEE 802.3 limits of 328-foot/100 m using any existing copper wiring previously used in alarm circuits, E1/T1 circuits, RS-232, RS-422, RS-485, CCTV and CATV applications. For environments where the 10/100/1000 LAN is being extended and network security is critical, Perle offers Managed Gigabit Ethernet extenders that support all authentication, authorization and accounting (AAA) security services used in corporate networks, including TACACS+, RADIUS, LDAP, Kerberos, NIS and RSA. To further protect IDs and passwords from someone 'snooping' on the network, Perle Managed Ethernet extenders provide secure management sessions by supporting SSH, SNMPv3, Telnet and HTTPS. These types of features are used when managing your corporate firewalls, switches and routers.
Plug and Play operation
Perle Ethernet extenders will automatically configure your VDSL interlink connection. The CO/CPE peer association will be determined automatically by the Ethernet extender. No need to set CO/CPE VDSL pairing.
With link pass-through the state of the 10/100/1000Base-T Ethernet connection is "passed through" the VDSL link to the 10/100/1000Base-T Ethernet connection on its remote peer. A managed switch on the remote end can then report the state (link up or link down) to its network management system so that any errors can be detected and recovered early.
Interlink fault feedback
Similar to the link pass-through feature, a loss of VDSL Interlink will drop the 10/100/1000 Ethernet ports on each end until the link recovers.
Some Ethernet equipment require a fixed speed and duplex be used or cannot auto-negotiate. By disabling auto-negotiation on the Ethernet extender, a fixed speed of 10, 100 or 1000 mbps as well as full or half duplex can be configured through DIP switches.
Detailed port statistics
To assist in troubleshooting links, an extensive list of ingress and egress counters for both copper and VDSL ports are available. These statistics can be viewed locally via the management module or from a central SNMP NMS on the network.
Pause (IEEE 802.3xy)
Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The Ethernet extender supports pause negotiation on the 10/100Base-TX copper connection.
The Ethernet extender is capable of performing a loopback on the copper VDSL Interlink port.
