over DS3 Switch (Ethernet to DS3 Switch) provides a four 100BaseT Ethernet and 100Base-FX
optical (optional) Ethernet interfaces on the user side which may be used to transport
Ethernet traffic over a DS3 link.
How it works?
In the event of the failure of
the data server / router connected to the "A / active" port of the DS3
Protection (Fail-Over) Switch, the DS3 line from the telephone company shall automatically
be "switched" to the data server / router on the "B / standby" port of
the DS3 Protection (Fail-Over) Switch. 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 DS3 Fail-Over Switch should
be used when the customer wishes to connect redundant (active and standby) DS3 equipment
(such as Routers) at the customers premises to a single DS3 service line from the
The DS3 Fail-Over Switch will automatically switch the DS3
service line from the telephone company between the ACTIVE DS3 data server / router and
the STANDBY DS3 data server / router. Should and whenever the ACTIVE DS3 data server /
router fail (or be removed from service), the DS3 line from the telephone company
automatically switches to the STANDBY DS3 data server / router without requiring any
customer or user intervention.
The DS3 Fail-Over Switch may also be accessed remotely by
the user to allow forced / manual switching between the two DS3 terminals through user
executable software commands using Telnet.
Allows the user to connect a DS3 line from the Telephone
Company and to switch it automatically between an active and a standby DS3 terminal at the

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 DS3 lines from the telephone company
Automatically switches the DS3 link from the Telephone

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
DS3 lines from the telephone company. The equipment may be used to create secondary /
backup systems at the customer premises to provide virtually uninterrupted service.
DS3 Switching Parameter
Loss of DS3 Signal (LOS)
The Loss of Signal condition
in a DS3 may occur due to:
The failure of the DS3 Port
of the customer premises equipment.
Or due to loss of power to
the customer premises equipment.
Or due to the disconnection of the DS3
cable between the protection Switch and the DS3 Port of the
customer premises equipment.
