1G Multiport Network Interface Device – Model 9145EMP

The 9145EMP is an Ethernet Network Interface Device (NID) with 4 User Ports for multiple services or customers. To keep access up for the multiple customers, the 9145EMP supports a LAG protected Network Link to keep connectivity up in case of a fiber outage or network switch port failure. Performance Measuring and Availability Monitoring gives you the tools needed to ensure the service contracted for is delivered. The 9145EMP’s expandable, flexible architecture allows addition of new features and applications without the need of hardware replacement. This protects your investment by providing for new industry standards and techniques with a simple software download. Supporting the same features and capabilities of the 9145E, the 9145EMP is key to delivering, managing and maintaining profitable Metro Ethernet Services and provide test points in the Metro Ethernet Network access.

9145EMP Application Overview


Data traffic from 3G and 4G/LTE Services greatly increases bandwidth requirements over voice only services and add the requirement for Ethernet Interfaces. When upgrading existing cell sites, often the existing TDM access is retained and the new Ethernet access is added. In both Upgrade and New sites, the preference is for a single access link for both TDM and Ethernet traffic. Existing SONET/SDH, Microwave and copper based system do not have the bandwidth available or require expensive upgrades to add Ethernet Capabilities. Metro Ethernet Services has become a popular solution to the bandwidth and connectivity needs.

The 9145EMP Multi-port NID is the solution when access for multiple Wireless Service Operators from a single site is needed or when T-1/E-1 connectivity, using TDM over Ethernet, is needed in addition to the Ethernet connectivity.

The 9145EMP terminates Metro Ethernet Services at the cell site. Each of its four User Ports supports the same features, functions and capabilities as available on the 9145E (9145E Product Page 9145E Application) including Advanced OAM, CFM, Performance Measuring, Service Availability Monitoring, C- and S- Tagging of Customer Traffic.

The four User Ports support terminating services at multiple customers and support both UTP and Optical (single mode and multimode) Ethernet Interfaces.

The 9145EMP’s cable diagnostics assure UTP Demarc connectivity to the BSE demarcation block. The 9145EMP’s cable diagnostics reports on cable faults, impairments and length, giving your network operations people the tool to remotely determine cable health, if the customer has cabling problems and what they are. This maintains high service availability and prevents unnecessary truck rolls.

Should the network link be oversubscribed, customer traffic on each port is classified into 1 to 4 priority queues resulting in up to 16 queues for the network link. Traffic is then queued onto the network link for transport on the Metro Ethernet Network. TDM traffic prioritization over Ethernet traffic means the latency, jitter and packet loss sensitive TDM traffic is delivered within specifications with performance degrading congestion impacting only the more tolerant Ethernet traffic.

The 9145EMP supports the 3G/4G/LTE connectivity you need by your customers and subscribers and maintaining high satisfaction, revenue protection and profitability.
