Orion’s DS3 Protection (Fail-Over) Switch allows the user to connect a single DS3 line from the telephone company to an "active", as well as to a "standby" DS3 terminal, such as data server, router etc. at the customer premises. In the event of a terminal equipment failure at the customer premises, the DS3 Protection (Fail-Over) Switch automatically "switches" the DS3 line from the service provider to the standby (working) DS3 terminal.

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 data network.

• 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 customer premises
• LOS (Loss of DS3 Signal) is the switching criterion between "Active" and "Standby" DS3 Ports
• Fail-Safe switching to Main (Port A) link in to event of equipment or power failure
• Available in a single DS3 line and a two DS3 line version
• Independent switching for each DS3 line (in the 2, DS3 line version)
• 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 DS3 line between the "active" and "standby" DS3 terminals, remotely, if required
• Dual AC (1+1 AC) or Dual - 48V DC (1+1 DC) power input.

• 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 Company between the "active" and "standby" DS3 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 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.

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 telephone company.

The DS3 Fail-Over Switch shall 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.
