Combined T1 Telephone and Internet
Service
An Integrated T1 line shares bandwidth between digital phone lines
and broadband Internet service. Typically up to 12 phones lines
can be accommodated. If the T1 line is set up to be a dynamic
T1, then any bandwidth not used for telephone calls is automatically
available for Internet access.
Channelized and Unchannelized
T1 Lines
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.
T1 and T3 Lines for Wireless
Backhaul
A WISP or Wireless Internet Service Provider needs a way to connect
the Internet to the tower radios. T1 lines and bonded T1 lines
are widely used for this purpose, as well as cellular tower backhaul,
because of their almost universal availability. T3 lines offer
28x the bandwidth of T1 lines but are typically more available
in larger metropolitan areas.
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.
