T1 vs DSL for Business Broadband
T1 lines set up as T1 Dedicated Internet connections give business
users guaranteed bandwidth of 1.5 Mbps both upload and download,
plus a SLA service level agreement to assure line reliability.
DSL is a "best effort" Internet service that is offered
without any service guarantee on a shared connection. Bandwidth
varies depending on how heavily other businesses are using the
Channelized and Unchannelized
A T1 line may be configured as a single large pipe offering 1.5
Mbps data transport or as 24 individual channels of 64 Kbps each,
ideal for use as individual outside telephone lines to support
Key or PBX business telephone systems.
What Are Pseudowires?
A pseudowire is a virtual "circuit" that emulates a
traditional digital telecom service but on a packet switched network.
MPLS networks are especially suitable for pseudowires. By using
a pseudowire circuit, you can get the point to point connectivity
you desire without having to re-engineer your facilities to accommodate
a different protocol network.
Virtual Private Networks Link
Many businesses now have more than one office location or need
to include other facilities such as warehouses and remote data
centers. A VPN or Virtual Private Network allows you to use dedicated
Internet connections as private network connections through data
encryption. A VPN solution is generally much less expensive than
extensive dedicated point to point circuits.
Bandwidth to Support Convergence
Convergence means combining or converging voice, data and video
onto a single network. Enterprises usually need to expand their
LAN bandwidth and set up a QoS or Quality of Service priority
system to give priority to real-time streams such as telephone
calls or video conference feeds, which are more sensitive to network
delays than data transfers. Most often, the common protocol for
convergence is IP.
