Chapter One Overview
1.1 Outlet
4/8/16E1 over Ethernet aggregation Gateway is a channelized Ethernet
gateway for interconnecting TDM and packet-based networks. The
Ethernet Gateway aggregates and switches Ethernet traffic into 4, 8 or
16 channelized E1 circuits, each supporting up to 31 Ethernet logical
channels (31 over N*64K). Ethernet traffic over channelized E1 lines
is aggregated and transferred to the packet-switched network via the
unit’s Gigabit Ethernet ports. The encapsulation method support
HDLC/PPP-BCP (RFC3518)/GFP-F.
1.2 Equipment Features
Support 4-port Ethernet electrical interfaces, 2- port Ethernet electrical
interfaces or 2-port fiber interface
，
16-port E1 channel, and make the
Ethernet data gathering into E1 channel.
Support maximum 2047 bytes and provide 2kBytes MAC address
buffer space
Support the Ethernet VLAN isolation function.
Single E1 channel support HDLC/PPP-BCP (RFC3518)/GFP-F
encapsulation, double E1 channel support GFP encapsulation.
Support E1 frame or un-frame application, and N*64K for framed
mode.
Provide Console, Telnet, WEB and SNMP Management.
Support software and firmware upgrade.
-48VDC/220VAC flexible redundant power inputs.
