Tight security
Secure routers include the features you need to protect your data from unauthorized access or corruption.
Virtual Private Networks (VPNs) provide secure communications for your offices over public infrastructures such as the Internet.
Network Address Translation (NAT) enables the router to “hide” the IP addresses on your private network from the Internet.

Technically Speaking
If you require reliable network connections between remote sites, T1 or E1 can fit the bill.
Both T1 and E1 are foundations of global communications. Developed more than 35 years ago and commercially available since 1983, T1 and E1 go virtually anywhere phone lines go, but they’re much faster. T1, used primarily in the U.S., sends data up to 1.544 Mbps; E1, used primarily in Europe, supports speeds to 2.048 Mbps. No matter where you need to
T1 and E1 are versatile, too. Drive a private,

Scaling T1
Basic T1 service supplies a bandwidth of 1.536 Mbps. However, many of today’s applications demand much more bandwidth. Or perhaps you only need a portion of the
1.536 Mbps that T1 supplies. One of T1’s best features is that it

can be scaled up or down to provide just the right amount of bandwidth for any application.
A T1 channel consists of 24
If you don’t need 1.536 Mbps, your T1 service provider can rent you a portion of a T1 line, called Fractional T1. For instance, you can contract for half a T1
If you require more than 1.536 Mbps, two or more T1 lines can be combined to provide

T1 lines multiplexed together for a blazing throughput of 44.736 Mbps, consisting of 672 DS0s, each of which supports 64 kbps.
T4 consists of 4032
These various levels of T1 service can by implemented simultaneously within a large enterprise network. T1’s cousin, E1, can also have multiple lines merged to provide greater throughput.
