E1 Failover (E1 Automatic Protection) Switch

Get Data Sheet

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.

E1 Protection Fail-Over Switch 12 E1 Ports 4 Links

Features & Highlights

Allows the user to connect an E1 line from the Telephone Company and to switch it automatically between an "active" and a "standby" E1 terminal at the customer premises. The user programmable switching criterion may be Loss Of E1 Signal, AIS and Loss Of E1 Frame.
Can accommodate upto four E1 lines - may be used switch between "active" and "standby" E1 terminals connected to upto four (or fewer) E1 lines.
Independent switching for each of the four E1 lines.
User programmable switching criterion - independent for each E1 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 E1 line(s) between the "active" and "standby" E1 terminals, remotely, if required.
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 E1 lines from the telephone company.
Automatically switches the E1 line from the Telephone Company between the "active" and "standby" E1 equipment at the customer premises, according to the customer-programmed 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 E1 lines from the telephone company. The equipment may be used to create secondary/backup systems at the customer premises to provide virtually uninterrupted service..

Application Note

The E1 Fail-Over Switch should be used when the customer is using a E1 line to connect to and install "active" E1 equipment and "standby" E1 equipment (such as a ROUTER or a PBX) at the customers premises.
The E1 Failover Switch shall automatically switch the E1 line from the telephone company between the ACTIVE E1 data server / router and the STANDBY E1 data server / router. Should the ACTIVE E1 data server / router fail or be removed from service, the E1 line from the telephone company automatically switches to the STANDBY E1 data server / router without requiring any customer or user intervention.
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.
