ETHERNET OVER TDM

Egate-100

Gigabit Ethernet over

TDM Aggregation Gateway

Egate-100 is a gateway for interconnecting

Gigabit Ethernet over channelized STM-1/OC-3

or three DS3 links. It is typically deployed in a

central location to aggregate Ethernet user

traffic received from remote devices, such as

RAD’s RICi Ethernet NTUs and FCD TDM access

devices, or third-party CPEs. Together with

these remote units, the Egate-100 constitutes a

complete access solution from the service

provider central site to the customer premises.

The Egate-100 Gigabit Ethernet over TDM

gateway leverages widely available PDH/SDH/

SONET networks to deliver carrier-class Ethernet

services to sites where native Ethernet is not

available.

Carriers can generate new revenue streams from

existing infrastructure, or expand out-of-region

network coverage by leasing lower cost

transmission lines as an alternative to digging

new infrastructure. Enterprises and utilities are

also able to take advantage of available SDH/

SONET transport for new Ethernet-based

applications.

Multi-site Carrier Ethernet aggregation

The Egate-100 can connect up to:

•

42 remote LANs over n x E1/T1 circuits, with

MLPPP or with GFP, VCAT and LCAS

•

63 or 84 remote LANs over E1 or T1 circuits,

respectively

•

126 remote LANs over fractional E1/T1

circuits

This unique capability enables service providers

and enterprises to deliver Ethernet Private Line

(E-line point-to-point) services at granular rates

from fractional E1 or T1 to n x E1/T1 channels.

The Egate-100 is MEF-9 EPL certified.

Since the Egate-100 functions as a bridge

operating over an SDH/SONET environment,

service providers can achieve a seamless

interconnection between customers connected

over the TDM network and customers connected

over the packet switched network, while

maintaining the same service level attributes.

Ethernet OAM is one of the cornerstones in the

transformation of Ethernet into a carrier-class

technology. The device supports single segment

OAM based on 802.3-2005 (formerly 802.3ah),

allowing for remote management and fault

indication, including connectivity check and

remote loopback.

NG-PDH encapsulation and bonding

The GFP, VCAT and LCAS standard protocols allow

service providers to dynamically allocate

bandwidth to their customers by simply changing

the number of E1 or T1 links bonded to the

virtual group, without the need to change the

device or stop the service. By incorporating

these enhanced capabilities, the Egate-100

enables higher user throughput, reduces delays

and minimizes service disruptions.

The Egate-100 replaces current solutions based

on expensive channelized STM-1/OC-3 or DS3

routers, or multi-box solutions based on

converter racks and switches. It offers the

following valuable advantages over these

alternatives:

•

Considerably reduced equipment cost

•

Single-box solution simplifies operations

•

Lower operating costs due to device

scalability, smaller footprint and low power

consumption

•

Increased service availability with port and

power supply redundancy

In order to ensure higher service uptime, the

Egate-100 features dual Gigabit Ethernet ports

with Link Aggregation according to 802.3ad, and

dual STM-1/OC-3 ports with 1+1 (MSP/APS)

protection.

Service differentiation

The Egate-100 features an advanced forwarding

model, including the following attributes:

•

User traffic classification according to ingress

port number, VLAN ID, VLAN priority, IP

Precedence, or DSCP

•

Class of service (CoS) mapping

•

Two-rate, three-color traffic policing

mechanism per CIR/CBS, EIR/EBS bandwidth

profiles

•

Configurable SP or WFQ queuing

These capabilities enable service differentiation

and SLA guarantees.

•

Aggregates Ethernet traffic over

channelized STM-1/OC-3 or three

channelized DS3 ports for hand-off to

PSN

•

Supports MLPPP as well as GFP (G.8040,

G.7041/Y.1303), VCAT (G.7043) and

LCAS (G.7042) standards

•

Enables scalable provisioning from a

fractional E1/T1 to bonded n x E1/T1

channels

•

Four SP and WFQ QoS priority queues

•

Traffic policing per flow and per EVC.CoS

•

Gigabit Ethernet and STM-1/OC-3 port

protection

•

Secure Telnet and Web applications,

SNMPv3 and RADIUS

•

NEBS-compliant

•

Optimized for IP DSLAMs and WiMAX

base station backhaul applications
