Voice Circuits

OET can help you get connected.



Telephone system circuits are used to connect various types of premise-based business telephone systems (PBXs, softswitches, key systems) to telephone company facilities and make the premise system functional. OET can help you get connected with phone numbers.

Types of circuits available

Analog Trunks and Lines - A trunk is a communication line between two telephone switching systems. A switching system is equipment either in a central office or at a customer premises, such as a PBX (Private Branch eXchange) or softswitch. Trunks can be analog or digital, inward only, outward only, two-way, DID (Direct Inward Dialing), ground start for voice mail systems, or tie. The various types of central office trunks connect customer equipment to the switching system at the central office. Tie trunks connect PBX/softswitch and Centrex facilities directly to each other. Types and availabilities vary depending on the providing service.

T-1 PRI - A digital transmission link that has a capacity of 1.544 Mbps (Million bits per second). A T1 (Trunk level 1) circuit consists of 24 channels of 64 Kbps (kilobits per second) circuits. Analog circuits are a point-to-point dedicated line. PRI (Primary Rate Interface) is a digital ISDN (Integrated Services Digital Network) telephone facility that can transmit both voice and data services and is often used for IP (Internet Protocol) telephony applications.
