3300 ICP Hardware User Guide

Constant current design with the loop current set at 25mA. If the loop range extends pass 600 Ohm, this circuit will revert to a voltage feed of approximately 2xVdc (design dependant parameter between 22-26 Vdc). The circuit remains active and the loop current will be dependant on the external loop impedance.

Supports a Ringing Equivalent Number (REN) of 3.

Capable of on-hook transmission. Used in conjunction with a centralized resource to de- liver calling line ID.

Positive disconnect (removal of battery from the ring lead).

Battery reversal (UK< LA< EU variants only - used for CLID).

Ground button detection.

Message waiting indication (dc voltage method).

Message waiting indication (class message).

Status led indicator per circuit.

Low level diagnostics.
