1+1 Automatic Ethernet Link Protection / Ethernet Failover Switch,
E1, T1 and DS3 Failover / Automatic Protection Switching (APS) Solutions

Valiant offers a wide range of Automatic Protection Switching (APS) and Failover Switches.

VCL-SafeComm-E, Ethernet Link Protection Switch provides 1+1 Network Protection between an "active” and "standby" IP networks. VCL-SafeComm-E can be used to provide link protection between IP networks across diverse domains such as fiber-radio; or fiber-satellite; or fiber-PSDN (Public Switched Data Network) to provide automatic fail-over protection to the “standby” network in the event of failure of the “primary” network.

VCL-SafeComm-E, Ethernet Link Protection Switch shall automatically switch and reroute all Ethernet traffic to "secondary” / “standby" IP network in the event of the failure of the “active” / “primary” network. This ensures minimum downtime that would have otherwise occurred upon the failure of the “primary” network.

Valiant also offers E1 Fail-Over (E1 Protection) Switch (12 E1 Ports - 4 Links) allows the user to connect a single E1 line from the telephone company to an "active", as well as to a "standby" E1 terminal, such as data server / router etc. at the customer premises.

In the T1 domain, T1 Fail-Over (T1 Protection) Switch (12 T1 Ports - 4 Links) allows the user to connect a single T1 line from the telephone company to an "active", as well as to a "standby" T1 terminal, such as data server / router etc. at the customer premises.

E1 and T1 Automatic Protection Switching equipment and solutions:

Application Note: 8/16 E1/T1 Links (24/48 E1/T1 Ports), 1+1 Automatic Protection Switching Equipment: This equipment is to be used when the customer wants to use two different E1/T1 links of the network to establish a 1+1 redundant path to ensure continued E1/T1 service between two points even if one of the network E1/T1 link fails. This example is also illustrated in the product data sheets for the respective products, provided below.

E1 and T1 Automatic Protection Switching equipment and solutions:

Application Note: 8/16 E1/T1 Links (24/48 E1/T1 Ports), 1+1 Automatic Protection Switching Equipment: This equipment is to be used when the customer wants to use two different E1/T1 links of the network to establish a 1+1 redundant path to ensure continued E1/T1 service bewteen two points even if one of the network E1/T1 link fails. Example - the customer may want to use E1/T1 Optical Fiber and an E1/T1 Radio link and to provide an ACTIVE and a STANDBY link between a BSC and a BTS so that when the E1/T1 Optical Fiber (ACTIVE) link goes down the STANBY / REDUNDANT E1/T1 Radio link automatically gets connected to provide continued connectivity and service between the BSC and the BTS. This example is also illustrated in the product data sheets for the respective products, provided above.

E1 Protection / E1 Redundancy (Fail-Over) Switch:

Application Note: The E1/T1 Fail-Over Switch should be used when the customer is using a single E1/T1 link to provide protection equipment to the customers premises by using one E1/T1 ACTIVE and one E1/T1 STANDBY equipment (such as a ROUTER or a PBX). The E1/T1 Failover Switch shall automatically switch the E1/T1 that is being received from the telephone company between the ACTIVE E1/T1 equipment and the STANDBY E1/T1 equipment. Should the ACTIVE E1/T1 equipment go bad or be removed from service, the E1/T1 link from the telephone company automatically gets switched to the STANDBY E1/T1 equipment without any customer or user intervention.

E1 Fail-Over (E1 Protection) Switch: Valiant's E1 Fail-Over (E1 Protection) Switch (12 E1 Ports - 4 Links) allows the user to connect a single E1 line from the telephone company to an "active", as well as to a "standby" E1 terminal, such as data server / router etc. at the customer premises.

How it works: In the event of the failure of the data server / router connected to the "A / active" port of the E1 Protection (Fail-Over) Switch, it shall automatically switch and connect the E1 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 data network.
