T1/DS1 broadband in Ohio uses two pairs of copper wire for transmission over telephone lines. An ordinary telephone line uses the DS0 transmission protocol, which carries 64 Kbit per second. A T1 line uses the DS1 protocol to combine the equivalent of 24 telephone lines for a total bandwidth of 1.536 Mbit per second.

Ohio broadband providers usually sell T1 lines to private customers in DS0 fractions. However, a small business will typically use a full T1 line to connect to the Internet and a larger business may use multiple T1 lines bundled together.

There are three primary factors to consider when you compare broadband carriers in Ohio:

1. Prices for T1 in Ohio vary in part according to your distance from the carrier’s Point of Presence. The further you are from the carrier’s POP, the more your T1/DS1 line will cost.

2. Major carriers usually own and operate their own networks, generally resulting in the best actual transmission speeds.

3. A channel bank is necessary to separate the DS1 data stream back into the 24 DS0 data packets. This device is relatively expensive to purchase or lease and represents a substantial investment for a small business.
