The device can
effectively utilize the redundant bandwidth of telecom operators’
existing TDM network to transport Ethernet data with low investment.
This equipment may be
used for the following purposes:
Bridging Ethernet LANs over existing TDM (E1) telecom network.
Extending Ethernet Networks utilizing TDM (E1) landline based
Using telecom network of E1s / PDH / SDH Microwave etc. carrying
E1s to transport Ethernet Data.
In all these cases the
equipment be always installed and used in pairs, with one terminal
being installed at either end (each side) of the network.
Typical Application 1:
Shared Link Mode:
In the “shared link
each LAN can view and talk to other LANs. Example: each LAN can
view and talk to all other LANs at same site or the corresponding
remote side. This mode may be selected for use if bandwidth
optimization and usage is of prime importance and the user is not
averse to sharing the E1 link resources with the other LANs being
transported on the same E1 link.
NOTE: In the “shared
link mode”, the VLAN switch must be OFF (The ethernet ports
are not isolated to each other on both sides of the E1 link.
Please refer to page 6 for VLAN switch settings.
Discreet Link Mode:
In the “discreet link
mode” each LAN is bridged to, and can only talk to its
corresponding LAN on the remote side. It can not talk to any other
LAN either at same side or the remote side. This mode may be
selected for use if the users do not wish to share the E1 link
resources with the other LANs being transported on the same E1 link.
Example: In the
discreet link mode, the LAN 1 (Ethernet Port 1 of the
equipment) only can talk to the corresponding LAN 1 (Ethernet Port
1 of the equipment) at remote side and can not talk to any other
LAN, either on remote side or same side.
