E1/T1 audio/Data Modular Multiplexer

Prodys

KRONOS
KRONOS E1/T1 Multiplexer is a system that allows transportation of voice channels, high quality audio and data across 2.048 Mbps or 1544 Mbps structured links (E1 or T1 circuits), using time division multiplexing (TDM). The Kronos multiplexer supports up to four E1 or T1 links. It is possible to drop/insert time slots across any of the connected E1 circuits. It is implemented using a modular construction on a common backplane architecture in 19" rack. It is possible to cascade up to 4 racks together. This all gives great flexibility in the choice of input and output modules depending on the requirements of each application.

•Modular 4U. high 19" rack.

•Ability to connect up to four E1/T1 circuits to one base device.

•Drop/insert across any of the connected E1/T1 circuits.

•AC or DC (48V) power supply.

•Option of redundant AC or DC power supply.

•Hot swapping of modules to make servicing and updating easier.

•Option to extend the configuration with additional racks (up to a maximum of 8 racks).

•Local or remote control and configuration through RS232 (Telnet) or LAN interface (SNMP).

•Ability to assigning time-slots for IP traffic dynamically. Routed interconnection of LAN through E1 circuits.

•Totally configurable audio modules by software: selection of analog or digital interface as well as encoding/decoding algorithm.

•Bi-directional module of synchronous data (two ports per module). The interface can be configured V35/X21 and as DTE or DCE.

•MODULES:


◦X21 module for synchronous data transmission N x 64Kbps

◦Encoder and decoder modules with analog and digital AES/EBU audio inputs and outputs and auxiliary data.

◦PBX interconnection module

◦TCP/IP Control Module.

◦Redundant Power Supply.

◦Extension module to cascade more subracks.



•AUDIO STANDARDS

◦ITU-T G711 & G722

◦ITU-T J57

◦ITU-T J41

◦ITU-T J42

◦ISO MPEG Layer II (mono/stereo)

◦ISO MPEG Layer III (mono/stereo)

◦Apt-X standard and enhanced 16,20 & 24 bits (mono/stereo).
