Product Description

Used Cisco ONS 15327 G1000-2 Gigabit Ethernet Card
Cerent 15327 Series

The Cisco ONS 15327 SONET Multi-service Provisioning Platform (MSPP) is a carrier class optical metro edge and access platform. The ONS 15327 SONET MSPP delivers supercharged SONET, integrated optical networking, unprecedented multi-services on demand, and radical economics, all in a compact, three-rack-unit footprint. The ONS 15327 SONET MSPP is a modular and scale-able platform that can deliver services from DS1, DS3, 10/100 Ethernet to Gigabit Ethernet services over OC-3 to OC-48 networks. The ONS 15327 is based on, and interoperable with, the industry leading ONS 15454 platform and providing an edge access complement to the ONS 15454 that can also can provide a smaller, more economical alternative to the ONS 15454.

The G-Series card supports the following "Carrier Class" Ethernet transport features:

• Network Protection—GE circuits can be provisioned for operation with or without SONET protection. Configuring a G1000-2 circuit over Unidirectional Path Switched Ring (path protection), Bi-directional Line Switched Ring (BLSR), Path Protected Mesh Network (PPMN), or linear 1+1, network failures are protected with sub-50msec restoration times.

• Client Interface Protection—The GE client interface can be protected via a interconnected device supporting the Gigabit Etherchannel protocol. Although designed to provide higher throughput links, Gigabit Etherchannel with more than one G1000-2 card can be leveraged to provide 1:1 G1000-2 card as well as client interface protection for an additional level of end-to-end circuit survivability.

• Low Latency Transport—Latency is minimized through efficient mapping of Ethernet frames to SONET payload.

• Hitless Ethernet Circuit Provisioning—No traffic hits (<50msec) are observed on active circuits when provisioning other circuits.

• Hitless Protection Switching of Common Cards—No traffic hits are observed when common cards switch from the working card to the protect cards, whether manually forced or the result of a common card failure.

• Hitless Software Upgrades—Upgrading the platform software to a future release will not impact Ethernet traffic provisioned over a G-series card.

• Flexible Provisioning Options—The G1000-2 is fully provisional via CTC or the widely used TL1 commands.

• Element Management—Supported by a proven element management system, Cisco Transport Manager (CTM)
