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
Advantage of Colocation Bandwidth
Colocation is locating your servers in a colocation facility,
also known as a carrier hotel. Advantages of this approach include
ready availability of low cost bandwidth including T1, DS3, Carrier
Ethernet and SONET Fiber Optic options. These data centers also
offer backup power, environmental control and high levels of security.
Logistics and Transportation
Trucking, warehousing, railroads and similar businesses need reliable
voice and data bandwidth. Point to Point T1 lines provide exclusive
and secure transmission between facilities for data transfers,
PBX telephone tie lines, and IP telephony.
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.
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.
