Digital telephony card for use in an operator system - Patent 4879738
. Sends a periodic digital milliwatt signal or idle channel termination from the digital side of headset receive to enable monitoring of the analog headset receice.. Transmits a periodic digital milliwatt signal or idle channel termination to central office 4 from the digital side of headset 32.. Transmits a periodic digital milliwatt signal or idle channel termination to both headset 32 and central office 4.. OPERATION MAINTENANCE The digital telephony card 30 contains a PCM level meter and a 1004 Hz 0dmB0, (digital milliwatt), transmitter.
DS2155 vs. DS21x5y: Software and Hardware Considerations
- Maxim/Dallas
. RCS, bit 7, was used to generate either a 7F idle code or the digital milliwatt pattern.. In the DS2155, the digital milliwatt pattern is generated using the T1RDMR1 (0C Hex), T1RDMR2 (0D Hex), and T1RDMR3 (0E Hex) registers.. See section 10.1 of the DS2155 data sheet for more information on generating the digital milliwatt pattern.

Introduction to Optical Fibers, dB, Attenuation and Measurements [Synchronous Digital Hierarchy (SDH)] - Cisco Systems
. This document focuses on decibels (dB), decibels per milliwatt (dBm), attenuation and measurements, and provides an introduction to optical fibers.. While dBm is the actual power level represented in milliwatts, dB (decibel) is the difference between the powers.
