Channel Modules
Intraplex produces a wide variety of channel modules for the ACS-160 Series multiplexers, including
these types:
●
Voice Modules:
Voice modules provide digital transport of telephony, fax and modem circuits.
Signaling options include E&M Types I, II, III, V, loop start/ground start, ARD, and transmission.
These modules provide
•
2-wire Foreign Exchange Office (FXO/FXS) PCM and ADPCM voice.
•
4-wire E&M PCM and ADPCM voice.
•
Wideband 7.5 kHz voice.
•
Motorola SECURENET
TM
secure digital voice.
●
Data Modules:
Data modules provide digital transport of one-way or full-duplex data circuits,
supporting a variety of data rates and formats including synchronous, asynchronous, and
plesiochronous. These modules include
•
High-speed synchronous data up to 1.984 Mbps for 10Base LAN, V.35, X.21, RS-449, and TTL.
•
10BaseT Ethernet LAN bridging.
•
Four-port asynchronous data up to 38.4 kbps for RS-232 and RS-449.
•
Five-port synchronous data up to 19.2 kbps for RS-232.
•
High-speed synchronous data that can be optionally decoupled from the network timing at any
data rate up to 1.984 Mbps.
●
Program Audio Modules:
Program audio modules provide digital transport for signals up to 20
kHz stereo. They are available with analog or AES/EBU input or output. These modules include
•
Linear, uncompressed 15 or 20 kHz stereo audio with minimum delay.
•
Enhanced Apt-X 4:1 compressed audio for signals up to 20 Khz stereo with low delay.
•
ITU-T J.41 audio that employs 14:11 instantaneous companding.
•
Full-duplex codec modules that provide MPEG Layer 2 and Layer 3 (MP3) compressed audio.
Each channel module’s transmit side converts its input into one or more 64 kbps time slots and places
this information onto the transmit bus on the midplane for multiplexing by the CM-5RB module
(Section 2.1.3 -
CM-5RB Common Modules
). Similarly, each channel module’s receive side takes the
