How it works?
In the event of the failure of the data server / router connected to the "A /
active" port of the E3 Protection (Fail-Over) Switch, it shall automatically switch
and connect the E3 line from the telephone company to the data server / router on the
"B / standby" port. This ensures minimum downtime - which would have otherwise
occurred due to equipment failure connected to the "A / active" port.
This equipment may be used to enhance the reliability and the efficiency of the customer's
The E3 Fail-Over Switch should be
used when the customer is using a single E3 line and install
"active" E3 equipment and "standby" E3 equipment (such as a
ROUTER) at the customers premises. The E3 Failover Switch shall
automatically switch the E3 line from the telephone company
between the ACTIVE E3 data server / router and the STANDBY E3
data server / router. Should the ACTIVE E3 data server / router
fail or be removed from service, the E3 line from the telephone
company automatically switches to the STANDBY E3 data server /
router without requiring any customer or user intervention.
Allows the user to connect a E3 line from the Telephone
Company and to switch it automatically between an active and a standby E3 terminal at the
customer premises. The switching criterion is Loss Of Signal.
Available in a single E3 line and a two E3 line version.
Independent switching for each E3 line (in 2 x E3 line
Built-in real-time clock / real-time logging maintains a
history of all events.
Remotely accessible over a TCP-IP networks. Allows the user
to access and carry out maintenance, or / and switch the E3 line between the
"active" and "standby" E3 terminals, remotely, if required.
Dual AC (1+1 AC), or Dual -48VDC (1+1 DC) power supply
Allows the users to install and maintain
active/standby/duplicate customer premises data networks/data servers, without bearing the
recurring $$ expense of leasing additional expensive E3 lines from the telephone company.
Automatically switches the E3 link from the Telephone
Company between the "active" and "standby" E3 equipment at the
customer premises, according to the customer-defined criterion
Improves equipment and data security.
Allows the user to co-locate the "backup /
standby" equipment in a different room/building and prevent any data loss arising out
of conditions of natural calamity such as fire, flooding etc.
Increases the reliability of the customer's data/IT networks
without having to bear the recurring and additional cost of leasing additional E3 lines
from the telephone company. The equipment may be used to create secondary/backup systems
at the customer premises to provide virtually uninterrupted service.
