ETHERNET OVER TDM

VLAN tagging and stacking

The Egate-100 associates a bridge port and a

TDM interface (e.g., a bundle of timeslots, a

clear channel E1/T1 or a group of bonded E1/T1

channels), in effect creating a virtual port

interconnecting the packet and the TDM

networks. Using the VLAN stacking (Q-in-Q)

attribute, a service provider VLAN is added to

the user traffic. This allows transparent delivery

of user traffic, keeping all the user VLAN

(CE-VLAN ID) settings intact, and enables a

seamless hand-off to the packet network.

SNMP management

The Egate-100 features flexible management

capabilities, including local management via an

ASCII terminal (RS-232). In addition, remote

management can be performed either inband or

out-of-band, using the network or user ports,

or the dedicated management port, while

maintaining separation between management

and user traffic via the use of VLANs. Advanced

FCAPS (Fault, Configuration, Administration,

Performance, Security) and diagnostic tools are

provided by RADview-EMS, RAD’s carrier-class

element management system, via a Web

browser.

The Egate-100 also supports a variety of access

protocols, including Telnet, SNMP, Web server, and

TFTP. Incorporated security features include Secure

Shell (SSH), Web-based Secure Socket Layer (SSL),

SNMPv3, and RADIUS. The Egate-100 supports

Syslog (RFC 3164), to enable system logs to be

forwarded to the network according to pre-

defined criteria.

Egate-100 is a compact, 1U-high, 19-inch wide,

standalone device in a metal enclosure. Its

channelized STM-1/OC-3 uplinks are available with

SFP optical and electrical modules. DS3 ports are

available with coax interfaces. The Gigabit Ethernet

ports can be ordered with 10/100/1000BaseT or

1000BaseSX/LX interfaces. The Egate-100 has one

or two AC or DC power supplies.
