Description
1647 Models and Positioning
The basic model of the 1647 EAD provides two 1Gbps Combo ports (UTP or SFP) for WAN connectivity and two SFP ports for customer fiber connectivity in addition to four 1Gbps UTP ports.
This device is positioned to provide cost-effective 1G Ethernet demarcation functions for both wholesale and retail Ethernet services and comes as a desktop version with redundant external power supplies.
Additional variants exist on the base model:
- Version with 4G CAT12 radio interface as main or backup link
- Â Version with 5G radio interface as main or backup link
This is to be able to provide Ethernet services over 4G/5G networks in several deployment scenarios. The most important scenario is to use the 4/5G radio to provide temporary wireless connections awaiting the installation of permanent fiber connections. Once the permanent connection is up and running, the same demarcation device can be used to provide backup in case of link failure. Another scenario is to use the 4/5G access network as primary link to deliver Ethernet services in remote places where a fixed fiber network infrastructure is not available or practical to install.
Metro Ethernet Services
The 1647 supports delivery of Ethernet services like E-LINE, E-LAN, E-Tree, E-ACCESS and E-Transit and is fully compliant with MEF 3.0.
OAM Monitoring
OAM monitoring of Ethernet data flows enables to monitor multiple quality parameters like service availability, Frame Delay, Inter Frame Delay Variation and Frame Loss. Some of these parameters are further processed internally to provide time-based statistics. Both point-to-point OAM monitoring (IEEE802.3ah) and end-to-end performance monitoring (IEEE802.1ag & ITU-T Y.1731) are supported on all Ethernet interfaces. Results can be retrieved in real time or can be further processed locally to provide statistical records based on 2h, 24h, 7 days or 1 month statistics. These processes can run in the background and can be retrieved when needed, avoiding the need to permanently keep track of thousands of parameters in a backoffice server
Service Activation Testing
The 1647 1G EAD supports SAT testing based on RFC2544 or with the more advanced Y.1564 and implements both traffic generator and traffic reflector. After completing the test, a birth certificate in plain text is delivered by the system for local storage or for archiving purposes. SAT testing allows operators to provide an intrusive end-to-end test to verify that the offered service complies to the agreed SLA agreements. The ability to perform these tests without going on-site enables operators to install, turn on and modify services at minimal cost.
