ISG 20, ISG 22 and ISG 24 - Ethernet over 10/100/1000

• Lack of consistent Ethernet interface at all locations - local and remote
• Lack of OAM (Operations, Administration and Maintenance)
• Lack of Performance Monitoring Capabilities
• Lack of SLA Assurance Capabilities
• No clear demarcation points between the Carrier and the End Customer
• No loopback capabilities
• Little or no testability of the carrier circuit
• No fault isolation features

• Setting a clear and consistent demarcation point between the customers' and the carriers' networks—no matter which vendors’ products are used in the core or edge networks
• Delivering a consistent management interface through standards-based operations, administration and maintenance (OAM) protocols
• Acting as onsite technicians, responding to remote service requests for loopbacks and other remote diagnostics, which keeps truck rolls to a minimum
• Monitoring and reporting on the end-to-end parameters of your Service Level Agreements (SLAs)

• ISG 20 - 10/100BaseT to 10/100BaseT
• ISG 22 - 10/100BaseT to 100BaseFX
• ISG 24 - 10/100/1000 TX/FX/LX/SX to 10/100/1000 TX/FX/LX/SX

• IEEE 802.3ah Ethernet OAM
• Two-port MAC Relay (TPMR) function aligned with IEEE's 802.1aj, 802.1ad, and 802.ag / ITU-T Y.1731 drafts
• Loopbacks
  • Layer 1, Layer 2 (MAC swap), Layer 3 (IP swap), Layer 4 (TCP/UDP Port swap)
  • Automatically reacts to in-band loopback commands from industry-popular Ethernet test sets
  • Individual VLAN loopbacks
  • Loopback on specific MAC source and / or destination address
  • Loopback on specific IP source and / or destination address
• Thru-traffic per-flow statistics (per VLAN, per Ethertype, per ToS, per CoS, per MAC, per IP, etc.)
• VLAN tagging / de-tagging
• VLAN stacking (.1Q in .1Q)
• Through traffic wire speed filtering (L2CP, BPDU, per-VLAN, Ethertype, Protocol type, MAC, IP, User defined)
• Dual Access Monitor Ports providing individual access to both signal directions, combined access to both directions, Layer 1 tapping and intelligent filtering
• Integrated copper TDR cable integrity test
• Dying Gasp (via 802.3ah or SNMP traps)
• Support for Jumbo frames
• Fault Propagation
• Link Loss Return

• Constant in-service monitoring of SLA parameters, including
  • Packet loss
  • Two-way delay (round trip latency)
  • Two-way delay variation (round trip jitter)
  • One-way delay variation (one-way jitter)
  • Continuous end-to-end path continuity check
• High Precision measurements with 1 microsecond resolution
• Works at Layer 2 and Layer 3
• Assures SLAs per VLAN / CoS / ToS / EVC
• Point-to-point or point-to-multipoint
• Multiple instance capable
• User-settable SLA threshold crossing alerts using SNMP traps

• Throughput: wire speed (100Mb/s at 100% utilization)
• Intrinsic Passthrough Traffic Latency (<0.8 microsecond (at all packet sizes)
• Intrinsic Passthrough Traffic Jitter (<0.8 microsecond (at all packet sizes)
• Intrinsic Latency for Intelligent Loopback (<0.8 microsecond (at all packet sizes)
• Intrinsic Jitter for Intelligent Loopback (<0.8 microsecond (at all packet sizes)
