T1 PRI For PBX Telephony
A T1 PRI, also called an ISDN PRI, is a "Primary Rate Interface"
providing 23 individual digitized telephone lines plus data such
as Caller ID on a single digital telephone trunk line. A PRI line
is usually much less expensive than a dozen or more analog business
Digital Signage Bandwidth Options
Digital signs, including large billboards, are easily and instantly
updated with data downloads. T1 and fractional T1 lines or VSAT
digital satellite connections are available even in rural areas.
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
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.
T-Carriers Offer Digital Telephony
T-Carriers, which include both T1 and T3 lines, offer digital
telephone trunking with multiple phone calls on a single physical
circuit. T1 lines can support up to 24 simultaneous phone calls.
T3 lines have 28 times the bandwidth of T1 lines and can offer
