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.
Product Overview – 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.
Product Overview – 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.
Product Overview – T1 Fail-Over (T1
Protection) Switch
Valiant's T1 Fail-Over (T1 Protection) Switch (12 T1 Ports

router etc. at the customer premises.
How it works:

/ active" port of the T1 Protection (Fail-Over) Switch, it shall automatically switch
and connect the T1 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.
