Teamlink 3101 Ethernet over PDH converter uses the next generation PDH technology such as generic framing procedure(GFP G.8040), Virtual concatenation (VCAT G.7043) and link capacity adjustment scheme(LCAS G.7042).

  SNMP-based element management software provides SNMP traps, status polling, and configuration. Remote element management is available in Teamview EMS.
  The Devices are managed in-band or out band 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, separated by different VLANs, thus ensuring traffic security based on port based or tag based VLAN.

Diagnostics :
  Remote and local loopbacks are used from problem isolation at the physical layer.
  A built in 511 test pattern generation and checking for the E1 circuits.
  Ping utility checks the health condition of the local and remote units.

       Product Features     


Teamlink-3101EE is intelligent converter connecting fast ethernet LANs over E1 circuits. They enable service providers and ISPs to supply transparent ethernet services, without interfering with user traffic.

Teamlink-3101EE have one E1 port and one 10/100 base TX port and 100mbps FX porrts. Packets are forwarded from the ethernet network to the TDM network at wire speed, fully utilising the expensive TDM circuit bandwidth.

The 802.1 priority scheme enables users to define four different QoS levels, according to the application requirements.

The fast ethernet handles frame size setting to 1522, 1526, 1654, 1784 bytes


Connects fast Ethernet LANs over E1 circuits.
