Loop-Start Operation

Loop-Start Service -- commonly known as “Plain Old Telephone Service” (POTS) -- is the primary analog signaling method used between telephone switches such as the Central Office (CO) and a telephone device. Loop-Start provides a way to indicate on-hook and off-hook conditions, which facilitates outgoing and incoming calls in a voice network.

Cable Specifications

The physical characteristics must meet or exceed FCC part 68 specifications.

Copper Cable -- Category 1

Either shielded (STP) or unshielded (UTP) twisted-pair is acceptable.

Gauge:	24 to 22 AWG
Maximum # Nodes:	2
Maximum Cable Length:	5 meters (16.4 ft) (Unit A and CO)
	5 km (3.1 mi) (Unit B and telephone)

When a customer wants to make an outgoing call, he or she takes a telephone device off-hook. This action completes the loop, which signals the CO that a customer desires to use the telephone line. To signal the customer of an incoming call, the CO applies a ring voltage to alert the customer.

The three states of the Loop-Start signaling protocol are described below:

Idle State (On-Hook)

1.The CO applies a battery voltage to the ring lead and monitors the tip-ring current for closure of the tip-ring.

2.The telephone device draws less than 10 µA of from the line while waiting for the superimposition of the ringing voltage over the ring lead.

Telephone In-Use (Off-Hook)

1.The customer takes the telephone device off-hook, drawing a minimum of 20 to 30 mA of current.

2.The CO senses the tip-ring current and issues a dial tone on the line.

3.Communication can now begin.

Central Office (CO) Rings the Telephone

1.The CO superimposes the ringing voltage over the ring lead battery.

2.The telephone device uses the ring voltage to operate the ringer, which alerts the customer of an incoming telephone call.

3.The customer takes the phone off-hook, which closes the tip-ring connection and allows the tip-ring current to flow.

4.The CO senses the DC current from the telephone device and connects the call to the telephone line.

5.Communication can now begin.
