Ethernet Option
6.1 - Overview
This chapter describes Sagem Link F Ethernet option. When installed, this option allows the user to
combine both E1 and Ethernet transmission. Two Ethernet applications are supported : bridging and
bandwidth allocation.
The Ethernet bridging involves automatic learning of the MAC addresses of the LAN which is
connected and forwards only packets destined to the remote end.
There is also an automatic bandwidth allocation available to monitor data flows and to maintain a list
according to MAC addresses or VLAN IDs (IEEE 802.1 Q).
The block diagram of a SAGEM-LINK F terminal with the Ethernet option is given on Figure 6.1.

Assuming that radio parameters have been already configured according to chapter 1 and 2
procedures, Ethernet specific configuration process consist of :
• Configuring the Ethernet bandwidth with the number of required additional E1
• Setting specific Ethernet parameters :
- Bridge or Bandwidth Allocation application (VLANs)
- Mac address filtering
- MII interface (10 baseT/100 BaseT, full duplex/half duplex, flow control, autonegotiation)
All these features are configurable from the SAGEM LINK F Pilot software.
6.2 - Ethernet and E1 Combinations Description
Sagem Link F equipments work at four data rates (2 E1, 4 E1, 8 E1 and 16 E1), with four different
channel bandwidths (3.5 MHz, 7 MHz, 14 MHz and 28 MHz), and with two modulation schemes
(QPSK and 16 QAM).
