EX14 – Carrier Class Transport NID

  • Demarcation and Media conversion
  • GbE Network Interface (SFP)
  • GbE Customer Interface (SFP or RJ45)
  • EFM Link OAM
  • CFM of End-to-end Service OAM
  • Loss and Delay Measurement
  • Digital Diagnostics Monitoring (DDM)
  • In-band Management
  • Redundant Power 24/48/60 VDC
  • Fanless Design

The EX14 is the ideal Carrier-class solution for Demarcation and Media Conversion at the edge of the network. Using small form pluggable (SFP) transceivers it supports a wide range of electrical and optical interfaces. Digital Diagnostics Monitoring (DDM) is fully supported to enable both on-site and remote checking of optical power levels.

Its robust metal housing and dual power connectors emphasize the Telecom grade quality.
The Transport NID supports CFM OAM IEEE 802.1ag connectivity fault management and ITU-T Y.1731 Frame Loss (LM) and Frame Delay (DM) measurement to be able to monitor and optimize Service Level Agreements (SLA).

The EX14 is supported by the AimNMS, which is an SNMP based management solution.
An API is available to facilitate the integration in existing equipment and management systems.
Both management options allow for provisioning and monitoring of relevant parameters and include a fail safe software upgrade mechanism.

Because of its small size and low power consumption, the EX14 is ideally suited for locations with restrictions on space and dissipation.

The EX14 has the following key features:

  • IEEE 802.1aj TPMR operation
  • EFM Link OAM IEEE 802.3ah
  • CFM Service OAM IEEE 802.1ag
  • ITU-T Y.1731 Performance Management
  • Link Pass Through (LPT) aka Link Loss Forwarding
  • Dying Gasp
  • Transparent to Synchronous Ethernet
  • Status LEDs for link, management, fail and power
  • Layer 2 Control Protocol (L2CP) processing with enhanced frame matching
  • Flexible mounting options
  • Low latency and wire speed GbE throughput

The EX14 supports Mobile Backhaul demarcation up to 80 km with comprehensive Connection Fault Management according IEEE 802.1ag and ITU-T Y.1731. Business Ethernet Services can be monitored up to the customer premises with media conversion to both electrical and optical interfaces.
