Key Features and BenefitsDesigned to demarc the edge of your network, the S2250/S3250 devices offer advanced packet performance metering and service creation directly from customer premises and cell-sites. With a full range of Ethernet rates and interfaces, the comprehensive S2250/S3250 family fits your network from end-to-end.
Service Assurance and FunctionalityPerformance Monitoring High-precision, hardware assisted, latency + jitter-free demarcation, monitoring and measurement of latency, jitter, frame loss andcontinuity, including 1-way performance validation with microsecond resolution. Multi-flow, multi-service, multi-site performance assurance enables real-time SLA assurance over any network. Supports point-to-point, multipoint & mesh topologies, unicast & multicast testing. In-Service Throughput Testing Verify the throughput of EVCs in-service, without affecting customer traffic. the S2250/S3250 units generate & analyze traffic flows up to full wire-speed at both layer 2 & 3. Intelligent Loopbacks In-service layer 1-2-3-4 loopbacksper-flow, defined by VLAN, Service-Level, MAC / IP addresses or any combination of layer 2-4 header criteria.Units respond to in-band loop-up commands from most third-party Ethernet test sets and monitoring systems, as well as via Y.1731 standards. Per-Flow Statistics Real-time statistics of live traffic at layer 1-2-3-4 (per VLAN, Ethertype, ToS, CoS, MAC, IP, etc.). Tapping & Monitoring Single or dual monitor ports providing filtered, real-time access to unidirectional or bidirectional traffic.
Service Creation and Traffic ControlService Mapping Create E-Line, E-LAN & E-Tree services directly at the demarc point -service mapping applies C/V-LAN tags (selective push) and/or configurable service class to traffic meeting detailed layer 2,3 & 4 criteria. Bandwidth Policing Limit upstream and downstream CIR/EIR by filtering criteria or for all traffic. Facilitates Carrier Ethernet service provisioning and ondemand/ incremental service upgrades. Wire-speed Filtering Filter wirespeed traffic at layer 1-2-3-4 (L2CP, BDPU, per VLAN, Ethertype, Protocol type, MAC, IP, User Defined). General Functionality Jumbo Frames Support: All functions supports Jumbo Frames up to 10,240 bytes at all rates (10/100/1000 Mbps). 3 –Way Redundant Power: Units can be powered using 5VDC, or dual -48V feeds, all mutually redundant. SNMP v1 & v2c: Support SNMP v1 and v2c for monitoring, alarms, OSS integration and unit configuration.
