DATASHEET

Version 3.0

Description

DATASHEETThe 8 x 1GbE module accepts one to eight
10/100/1000 BaseT signals, provides rate policing
and VLAN tagging, and transfers them to theMD8000 SW-CNT modules.

8 x 1GbE, 8 Port 10/100/1000 BaseT
Ethernet Line Module

A 4 x 1GbE line module (with rear panel SFPcage) is also available that accepts one to four
10/100/1000 Ethernet BaseT signals

The 8 x 1GbE module accepts one to eight 10/100/1000 BaseT signals, provides
rate policing and VLAN tagging and transfers them to the MD8000-SW-CNTmodules. In the receive direction, the 8 x 1GbE module accepts Ethernet packets
transferred from the SW-CNT and provides one to eight unique 10/100/1000 BaseT
output signals.

Applications• LAN Extension• WAN Access Circuit• Network Management

Eight completely independent bi-directional GbE channels ensure that data on theindividual ports is kept separate, permitting operation at full wire speed rates withtotal isolation. Auto-Negotiation is supported on all 8 ports. In addition, customer
loopback and continuity checking functionality is also provided to facilitate circuit
setup and operational troubleshooting.

• Telemetry• File Transfer
Features & Benefits• Eight, 1GbE fully independent Ethernet Circuits(Note: a 4 x 1GbE version is also available)

The 8 x 1GbE module has four encapsulation/decapsulation modes of operation:
Transparent, Double Tag, Tunneling and Tag Exchange (Over Write). All modes
handle packets up to Jumbo Frames (i.e. maximum of 9022 bytes in length
including headers and FCS).

• Automatic Rate Negotiation• 4 Transport/Operation Modes:- Transparent- Double Tag- Tunneling- Tag Exchange (Over Write)

Input filtering and rate policing is provided on each individual Ethernet circuit
to guarantee that data bursts cannot disrupt overall traffic flow. Either optical orelectrical SFPs can be used on the rear panel.

• Input Filtering and Rate Policing to eliminate
traffic disruptions
