DS3 Failover (DS3 Protection) Switch - Upto 2xDS3 Links


Product Overview

AceCom'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.


Ethernet 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 data network.


Application Note


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 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.


Features

  • 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.

Benefits

  • 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.

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.

DS3 Switching Time

  • Change over time from Main Link to the Standby Link is user configurable from 10ms to 3000ms

  • Recovery Switching time from Standby Link  to Main Link is also user configurable from 10ms to 9999ms.


System Management and Access

  • Windows XP and Windows 7 compatible GUI

  • Telnet - CLI (Command Line Interface)

  • SNMP V2 (MIB File provided with the equipment)

Monitoring and Control Port

  • Serial Management Port (RS232) COM Port

  • USB Serial Interface COM Port

  • 10/100 BaseT for remote management over a LAN / TCP/IP network
