NNI Filters increased to 2048

•OPTera Metro Release 12.0 augmented the number of individual NNI filters to 2048. The 2048 filters are shared across any Ethernet ports on the 4x100BT, 4x100FX and 2xGigE cards which are configured as NNI.

Optical Ethernet-Private Line (OE-PL) services using 10/100 Ethernet

One of the key services within Optical Ethernet is the Private Line (OE-PL) Service. An Ethernet private line has the same service characteristics as a traditional TDM based DS1, DS3 or OC-n private line service but uses Native Ethernet as the interface. Ethernet frames are relayed transparently between two Ethernet ports. The Ethernet frames are mapped into circuits either at full or partial rate.

End users can benefit from Native Ethernet interfaces and no longer require any adaptation to traditional WAN interfaces (T1/DS1, T3/DS3, OC-n). This simplifies the co-ordination of interfaces between the Carrier and Enterprise, and moves to a simple ’plug-and-play’ model for WAN services based on Ethernet 802.3.

The 2x100BT-P2P circuit pack available on OPTera Metro 3500 are used to offer OE-PL service.

2x100BT-P2P circuit pack

The 2x100BT-P2P circuit pack has the following functionality:

•Dedicated private point-to-point Layer 1 connectivity using standard STS-1 or STS-3c connections

•Same look and feel as other OPTera Metro 3500 TDM tributaries such as DS3 or EC-1

•2 x 10/100 LAN ports independently configurable as 10BASE-T or 100BASE-TX

•Capability to interconnect back-to-back the Ethernet interfaces of the 2x100BT cards

•Network protection using UPSR, BLSR, and 1+1 linear

•Fully managed through Site Manager (does not support SNMP/ BCC as in the case of OPE circuit packs)

•Ethernet and WAN Operational Measurements

Note: The 2x100BT-P2P circuit pack only supports far-end link conditioning at 100 Mb/s (100BASE-TX).

The 2x100BT-P2P circuit pack separately maps two 10/100BASE-T ports into STS-1/STS-3c SONET signals for transport across a SONET domain. The 2x100BT-P2P circuit pack has two logical sides to its interface: the LAN side, which contains the Ethernet ports; and the WAN side, which interfaces with the STX and VTX-series circuit packs at the SONET level. Four MAC addresses are allocated for each 2x100BT-P2P circuit pack.
