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 phone lines.

Channelized and Unchannelized T1 Lines
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.

Medical Imaging Transmission
Medical images, such as those generated by Teleradiology equipment, have large file sizes due to high resolution. Rapid transmission between hospitals and medical centers requires high availability, high bandwidth telecommunication services. For smaller offices or infrequent use, a T1 data line might easily suffice. For medium and larger facilities, T3 lines and fiber optic carrier services are recommended.

T1 Digital Cross Connect Systems
A digital cross connect system, often abbreviated DCS or DCAS, allows you to switch traffic among your T1 lines. It will even reach into the line to connect individual channels or timeslots rather than the entire circuit. A manual device that cross connects T1 lines is called a DCX or patch panel.

What is POTS mean?
POTS is a telecommunications industry acronym for "Plain Old Telephone Service." POTS lines are the analog telephone lines that have been trenched or dropped into nearly every business and residence in the country. POTS service is based on standards that have been well established for over a hundred years.
