Section 1 – Introduction
The PT-353 and PR-353 program audio modules provide data transport of up to 22.5 kHz stereo
program audio. These modules plug into Intraplex network access products, combining program audio
with other audio, voice, and data traffic for transmission over T1, E1, and other high-speed digital
links. Each module has two separate channels and operates at sampling rates of 32, 44.1, and 48 ksps
to provide transport of stereo program signals of 15, 20, or 22.5 kHz bandwidth respectively. Reed-
Solomon forward error correction (FEC) helps to eliminate clicks, pops, and noises caused by
transmission line errors. These modules support A and B channel status transport and 9600 baud
ancillary data. The modules’ key features include
●
48, 44.1, or 32 ksps sample rate for up to 22.5 kHz audio bandwidth.
● Linear uncompressed audio, insuring excellent audio fidelity with low delay.
● Reed-Solomon FEC.
● Sample rate adaptation on AES/EBU input preserves the data rate throughout the system.
● Built-in user selectable sample rate converter.
● External AES timing input to synchronize the output stream to facility AES timing.
● Both AES/EBU and analog inputs and outputs on each module.
● Built-in 9.6 kbps AUX data channel.
