T1 Lines As Studio Transmitter
Using point to point T1 lines offers radio stations a digital
STL that does not require FCC licensing or line of site between
studio and transmitter.
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.
Channelized T1 vs ISDN PRI
T1 lines can support two protocols of switched circuit telephony.
Channelized T1 lines offer 24 phone lines using in-band signaling.
ISDN PRI, or Primary Rate Interface, offers 23 phone lines and
common channel signaling that can include data such as ANI Automatic
Number Identification or Caller ID.
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.
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
up to 672 simultaneous phone calls for large enterprise or call
