NOTE

Measure noise with 50 kbit weighting
characteristic approximating a filter with a
passband of 40 Hz to 30 kHz. Background
noise level or impulse noise level is referenced
from 56/64 kbps data rate in TR62310.

6. MAINTENANCE

The Total Reach DDS-DP does not require routine
maintenance for normal operation.

Compliance Requirements

CAUTION

This product for installation in a restricted
access location in a Type B or E enclosure
only.

Max input current @ max load = 165 mA @ -48 Vdc.

Max output current @ max load = 41 mA @
-140 Vdc.

NOTE

The 50 dB AML limit includes 6 dB of signal
margin to account for potential near-end
cross talk (NEXT) from other digital services
that may be provisioned in the same binder
group.

Loop length should not exceed 50 kft.

Bridged tap length should not exceed 12 kft.

Background noise level should not exceed
34 dBrn.

Impulse noise should not exceed
-40 dBm, (+50 dBrn).
