TEAMLINK 3101 Managed Fast Ethernet Over E1/T1 Converter/Router is an intelligent converter connecting 10/100mbps Fast ethernet over fractional or full E1 circuits, that enable service providers and ISP's to supply transparent ethernet services over SDH and PDH circuits.

SNMP based element management software provides SNMP traps, status polling, and configuration download. Remote configuration is also possible through Telnet & SNMP using in-band management.

The devices are Managed inband from the Fast ethernet user port or via the TDM port. Management traffic and user Ethernet traffic are transported together on the same Ethernet flow, seperated by different VLANs, thus ensuring traffic security.

     Remote and local loopbacks are used for problem isolation at the physical layer.
     Abuilt-in ping utility checks IP connectivity by pinging remote IP hosts.

Sends alarm notification to Manager IP addresses for the following
     Ethernet: Up/Down
     Loopback : On/Off
     If the ethernet error packets or collusion packets are reached more than threshold values.

     Teamlink 3101IETH Managed Fast Ethernet Over E1 Converter
     AC/DC power cord or adapter plug

       Product Features     

Key Features

HDLC / GFP-F Encapsulation

Supports CRC - 4 multiframe auto adoption

Loopback detection at WAN or E1 side and discards the ethernet packets to protect the ethernet network from jamming.

Complying GFP (G.8040, G7041/Y.1303)HDLC framing compatible with the RJ-107.

Discards over sized and undersized packets

Support STP/RSTP

The fast ethernet bridge handles 1784 bytes frames supporting for VLAN applications and other protocols requires large frame sizes

4k Mac address table learning.

Broadcast storm filtering support

Mac table display for each ethernet port and E1 side also

The teamlink 3101 ethernet to E1 converter can interoperable with third party converters with standard HDLC or GFP framing that can eliminate pair of converters for each link

Auto MDIX for auto TX/RX

4 levels of Qos based on four priority queues.

VLAN tagging and Untagging

Ethernet transmit, receive, Collision and error packets display.

Inband and out of band management access via

     ASCI terminal
