Emux Solution for E1 Service Delivery

Emux offers 4,8 or 16-port E1 multiplexing over fibre

  • Protocol transparent E1 extension over fibre
  • Cost effective 4, 8 or 16-port E1 units available
  • Resilient fibre uplink using SFPs
  • External alarm relay port
  • Local management port for configuration and diagnostics
  • Remote configuration and testing of units across the network
  • Comprehensive performance monitoring of both device and line
  • Built to European standards
  • Remote management using SNMP and Telnet
  • Optional -48 volt DC supply
  • Alternate product for Probot 3004

The Emux offers extension of multiple E1 ports (120 ohm RJ45 connectors) over a resilient fibre port supported via a pair of SFP connectors, with 4, 8 or 16-port E1 product variants available.

The Emux is completely transparent to E1 protocol and so all E1 voice and data protocols can be supported including PRI ISDN-30, QSIQ, DPNSS, DASS, IP, etc.

The resilient 1+1 fibre interface offers automatic switch-over when a fibre fault occurs.

SFP fibre modules enable many types of fibre interfaces to be supported including multimode, singlemode, CWDM and DWDM.

The Emux has several LEDs for displaying current status, plus comprehensive configuration and diagnostics via a menu driven user interface.

Using a dedicated management channel pairs of Emux units can communicate with each other, allowing configuration and status checking of the remote unit.

Remote management can be performed via either SNMP, Telnet or a Web interface.

Whilst the Emux product range uses industry standard user exchangeable SFPs, it is recommended that these are purchased from Metrodata to guarantee their specification and compatibility with each other.

Emux delivering multiple E1 services over fibre
Emux delivering multiple E1 circuits over fibre

This application shows an Emux transporting up to 16 E1 circuits across a redundant fibre link, although this application will also work perfectly well with a single fibre. The Emux provides transparent E1 extension and so all E1 voice and data protocols can be supported including PRI ISDN-30, QSIQ, DPNSS, DASS, IP, etc. Product variants with 4, 8 or 16 E1 ports are available. The resilient fibre port has dual SFP connectors and so different SFPs can be used to support a variety of fibre types and distances.

Emux: extending multiple voice & data services over fibre
Emux extending multiple voice and data circuits over fibre

This application shows Emux units being used to extend voice and data WAN services from a campus communications centre (the primary site) to multiple outlying remote sites. As communications infrastructures are merged together to make efficiency savings it is becoming increasingly important to extend these services across the campuses. This network topology is particularly well suited to hospitals, universities and other large campuses, although it can also be used across Metro area networks where suitable fibre resources are available.
