Multi-Protocol Copper Access Framer
CopperNode™ is a highly integrated Multi-Protocol Framer capable of mapping both Telecom and Datacom traffic into copper based transport formats such as DS3/E3 and DS1/E1. It is equipped with both leased line and data service client interfaces such as DS1/E1 and 10/100/1000 Ethernet and also offers a generic SPI-3 packet interface to allow for transport of other protocols. It supports 1:1 mapping of Ethernet clients into PDH transport containers as well as Layer 2 aggregation of multiple Ethernet clients into a single PDH transport container with VLAN and Q-in-Q.
Interfaces
- Equipment / client side:
- 4 x Ethernet / Fast Ethernet via SMII
- 1 x Gigabit Ethernet via GMII
- 6 x DS1/E1
- SPI-3 Packet Interface

Description
The CopperNode multi-protocol framer is designed to enable rapid development of next-generation Metro Ethernet and PDH transport solutions for existing, widespread copper based PDH infrastructures. The combination of Gigabit and 10/100 Mb/s Ethernet client ports and a packet co-processor interface along with DS1/E1 client ports supports delivery of current and future revenue generating services. Integrated DS1/E1 and DS3/E3 network ports also allow for transport over a variety of leased or owned facility types.
Using standardized Virtual Concatenation, individual transport links can be bonded together into higher capacity virtual links. The integrated Link Capacity Adjustment Scheme (LCAS) protects against member link failures and also provides a mechanism for increasing or decreasing the bandwidth of any virtual link by changing the number of members. CopperNode supports both Frame Mapped GFP and HDLC based packet encapsulation to provide compatibility with existing and emerging network equipment from multiple vendors. CopperNode also allows for onboard Layer 2 aggregation of multiple Ethernet client flows into a single transport container.
As with all Galazar IC technology, CopperNode is fully integrated in Galazar's industry leading and field proven configuration and management framework. This framework provides advanced capabilities such as warm start, interrupt management and a wide variety of troubleshooting tools, and is accompanied by extensive hyperlinked documentation and customer system support.
