Prodys, Kronos. E1/T1 audio/Data Modular Multiplexer

A multiplexer system that can carry voice, high quality audio, video and data channels.

Prodys, Kronos. Overview.

The Kronos E1/T1 multiplexer from Prodys is a system that can carry voice channels, high quality audio, video and data over E1 (2.048 Mbps) or T1 (1544 Mbps) structured links. (E1 or T1 circuits) using time division multiplexing (TDM)

The Kronos multiplexer supports up to four E1 or T1 links – four E1 links can be aggregated to give a total 8Mbps capacity. It is possible to drop/insert time slots across any of the connected E1 circuits. It also supports drop/insert of the 64Kbps time slots in any of the connected E1 circuits. Hot swap modules and redundant power supplies are also supported.

This all gives great flexibility in the choice of input and output modules depending on the requirements of each application

Prodys, Kronos. Specification.

Base Device

  • Modular 4RU, 19” width rack.
  • Up to 4 E1 or T1 Multiplexed modules with drop insert and automatic failover capabilities.
  • X21 module for synchronous data transmission N x 64 Kbps.
  • Encoder/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.
  • SNMP management software.
  • Extension module to cascade up to 15 base devices.

Audio Standards

  • ITU-T G711 & G722.
  • ITU-T J57.
  • ITU-T J41.
  • ISO MPEG Layer II (mono/stereo).
  • ISO MPEG Layer III (mono/stereo).
  • APTX (Audio Processing Technology) option.

Power Supply Modules

The base device includes two power supplies:

  • AC POWER SUPPLY MODULE 230V.
  • DC REDUNDANT POWER SUPPLY 48V.

If a power supply fails, the base device will change over to the spare power supply without interruption. LED monitoring of status and power supply failure

E1 Module

E1 circuits are full-duplex with 2Mbps capacity in each direction. The E1 module supports mux/de-mux signals over this 2Mbps circuit. Up to two interfaces per module for the connection ot two E1 links (2 Mbps each).

The multiplexer supports up to two dual E1 modules, that is, four E1 links (2 Mbps each). The multiplexer allows drop/insert functions among any of the four E1 connected circuits. Interface: CCITT G703 Connector: RJ45 and BNC75½ Binary speed: 2048Mbps +/- 50ppm Plot format: CCIT G704 Line code: HDB3 CCIT G703 and AMI Impulses format (galib) Co/contra-directional operation Impedance: 75½ or 120½

Control Module Main Functions
  • To manage the system. Route IP, up to 20 time slots can be allocated.
  • To work as an additional input/output synchronous data module.
Interfaces
  • Asynchronous port for connecting a VT-100 compatible terminal to configure the multiplexer.
  • LAN RJ45 10Base-T.

This module is also a router for direct LAN connection to configure the multiplexer using TCP/IP protocol (Telnet or SNMP). This module configures and controls input/output modules. It facilitates switching between PCM buses and E1 links according to the slots assigned by the user. The Multiplexer always keeps one slot of the E1 link reserved for the control module in order to manage the remote multiplexers. The control module monitors the system state and reports back to the management software. Maintains systems configuration information for automatic re-initialisation.

Data Modules

Synchronous Data Module
  • Allows synchronous transmission of data at N x 64Kbps.
