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 below.

Links (48 T1 Ports) Protection Switching |
Used to protect upto 16 T1 Links (48 T1

| E1
Protection Switch (1+1 APS) |
Allows the user to design 1+1 (protected)
redundant E1 routes on similar (fiber-fiber), or complementing (fiber-radio) transmission
mediums. It also allows the selection of only a few critical time-slots of the primary
route to be re-routed on the E1/T1 link on the redundant / standby route in the event of
the failure of the primary route, if the total carrying capacity of the stand-by redundant
route is smaller than that of the primary route. |

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.
Valiant's 4 Link (12 E1 Ports) E1 Protection / E1
Redundancy (Fail-Over) Switch allows the user to connect upto four E1 lines from the
telephone company to "active", as well as to "standby" terminal(s),
such as data servers / routers etc. at the customer premises.
In the event of the failure of the data server(s) /
equipment connected to the "A / active" ports, the E1 Protection (Fail-Over)
Switch shall automatically switch and connect the E1 line(s) from the telephone company to
the data servers / routers / equipment connected to "B / standby" ports. This
ensures minimum downtime -that would have otherwise occurred due to equipment failure.
Enhances the efficiency of that network.
Product Overview T1 Protection (Fail-Over) Switch
Valiant's 4 Link (12 T1 Ports) T1 Protection / T1
Redundancy (Fail-Over) allows the user to connect upto four T1 lines from the telephone
company to "active", as well as to "standby" terminal(s), such as data
servers / routers etc. at the customer premises.
In the event of the failure of the data server(s) /
equipment connected to the "A / active" ports, the T1 Protection (Fail-Over)
Switch shall automatically switch and connect the T1 line(s) from the telephone company to
the data servers / routers / equipment connected to "B / standby" ports. This
ensures minimum downtime -that would have otherwise occurred due to equipment failure.
Enhances the efficiency of that network.
