T1/DS1 broadband in Indiana 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.

T1 services are usually available in DS0 fractions for private customers wanting access to broadband. Indiana providers will typically use a full T1 line to connect a small business to the Internet and a larger business may need multiple T1 lines bundled together.

There are three primary factors to consider when you compare T1 Internet providers in Indiana:

1. Prices for T1 in Indiana 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.
