T1/DS1 broadband in Hawaii 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 Internet providers in Hawaii 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 larger business may use multiple T1 lines bundled together.

There are three primary factors to consider when you compare broadband services in Hawaii:

1. Prices for T1 in Hawaii 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.
