This application allows you to apply delay, attenuation, and/or filtering to a received signal on any number of timeslots. Delay/Attenuate Timeslots is an "input-process-outpu
t" application, that is, a block of data is retrieved from the Rx Data Source; is processed by delaying, attenuating, and/or filtering it; and then retransmitting the processed block on the Tx Destination. You may also mix in additional signals from a number of sources, including
Speech and/or Noise signals from files
Speech signals inserted via VF input
Gaussian noise signals generated internally
Transmitted signaling bits may be Onhook/Offhook, user-specified, or passed through from received to transmitted timeslots.Click here to view the Delay/Attenuate Timeslots screen.
The Delay/Attenuate Timeslots application may receive and transmit on either one or two boards. There are a number of different operating configurations, the most common and useful are:
Looping back a processed signal - Applying delay, attenuation, and filtering to a received signal and retransmitting the processed signal on the same board on which it was received. Speech and/or noise may also be mixed in. Click here to view a diagram of this configuration. Note that the layout of the Delay/Attenuate Timeslots application dialog closely matches with this diagram.
Applying pure delay to a signal. A received signal is delayed before being retransmitted.
Inserting a Simulated Echo Loop. A two-board system is inserted into a T1 or E1 trunk and is used to simulate an echo path having known characteristics. Click here to view a diagram of this configuration.
The layout of the Delay/Attenuate Timeslots application has been designed to closely resemble the above block diagrams. Click here to view an illustration of this resemblance for one such configuration.
