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.

RJ-45 twisted pair line is specified as follows:
1)1, 2 used to send; 3, 6 used to receive; 4, 5，7, 8 are bi-directional lines.
2)1, 2 must be pair twisted; 3, 6 pair twisted; 4, 5 pair twisted; 7, 8 pair
twisted.
Making of straight-through line: both heads are connected as per T568B line
sequence standard. Making method of crossover line: one head is connected
as per T568A line sequence while the other head is connected as per T568B
line sequence. The follows are specific connection conditions:
1) The device is connected with PC and router: straight-through line shall be
adopted with the same connecting method on both ends of network line.
2) The device is concatenated with switch (or HUB): crossover line shall be
adopted with different connecting method on both ends of network line.
