Combined T1 Telephone and Internet
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
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.
Fractional T1 Service as a
Not all businesses need the full 1.5 Mbps of a T1 line, but want
higher availability and the dedicated bandwidth offered by T-carrier
digital service. In many cases, fractional T1 services offers
a fraction of the bandwidth at a lowered monthly lease price.
Fractional T3 service may also be available for bandwidth needs
between 1.5 and 45 Mbps.
T1 Line Bandwidth Explained
A T1 line is typically referred to as having a bandwidth of 1.5
Mbps. The precise line speed is 1.544 Mbps. However, the usable
bandwidth or payload is actually 1.536 Mbps. The difference is
8 Kbps which is used for line framing to keep the transmitting
and receiving ends of the circuit in synchronization.
