Ethernet Service Support
3.12 The Tellabs 7300 NEs provide the following Ethernet service support:
• Ethernet UNI Type I (MEF 13)
• Ethernet Services Definition (MEF 6 and MEF 10.1)
-E-Line/E-LAN
- Service multiplexing
- Uses IETF-based bandwidth profiles: trTCM = CIR/CBS/PIR/PBS
• Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL), and
Ethernet LAN (E-LAN) services delivery (MEF 9 and MEF 14)
trTCM 3.13 The Two Rate Three Color Marker (trTCM) meters Ethernet flow and
marks its packets either green, yellow, or red. A packet is marked red if it exceeds
the Peak Information Rate (PIR). Otherwise it is marked either yellow or green,
depending on whether or not it exceeds the Committed Information Rate (CIR).
The trTCM is useful, for example, for ingress policing of a service, where a peak
rate needs to be enforced separately from a committed rate.
Ethernet Interface Support
3.14 The Tellabs 7345 Switch provides 10/100/1000 Base-T, 1GbE, 10GbE,
and 100BaseFX interfaces by installing the appropriate SFP/XFP. For Tellabs
7345 Switch supported SFP and XFP options, refer to the Tellabs 7300 Software
Release Document. Tellabs recommends using only Tellabs parts to ensure
interoperability; however, the Tellabs 7345 Switch supports third-party SFP and
XFP pluggable optics.
3.15 The Tellabs 7325 Switch provides 10/100/1000 Base-T, 1GbE, and
100BaseFX interfaces by installing the appropriate SFP. For Tellabs 7325 Switch
supported SFP options, refer to the Tellabs 7300 Software Release Document.
Tellabs recommends using only Tellabs parts to ensure interoperability; however,
the Tellabs 7325 Switch supports third-party SFP pluggable optics.
Ethernet Packet Support
3.16 Supported features include MAC Bridging, VLAN Bridging, an 802.3
compliant MAC client interface, Packet security, Packet fault management, Packet
performance monitoring, multicasting, and Tellabs 7191 craft station.
