Terminating Impedance: 600 Ohms nominal
Trunk balance impedance (selectable): 600 Ohms nominal or complex Z
[350 Ohms + (1 k Ohms in parallel with 0.215uF)]
Impulse Noise
On 95% or more of all connections, the impulse noise is 0 count (hits) in 5 minutes
at +55 dBrnC (decibels above reference noise with C-filter) during the busy hour.
