AT-TN119-A 8 Port T1/E1 Circuit Emulation Service Module

Circuit Emulation Service Enables

Delivery of T1/E1 over Ethernet

Transport

Migration from TDM to a converged Ethernet-

based network requires a means to compliment

the delivery of next generation packet-based

services with the delivery of traditional TDM-

based services.The CES8 (AT-TN119) gives the

iMAP the ability to provide transparent

transport for 8 T1/E1 circuits over an Ethernet

network.

TDM to Ethernet interworking is achieved using

the same industry standards for TDM Circuit

Emulation Service over Packet (CESoP) being

defined by the IETF, Metro Ethernet Forum,

MPLS Forum, and ITU-T.This interworking

technology is extremely robust and overcomes

the challenges of delivering TDM services over

an all IP packet network.

The CES8 automatically compensates for

packet network congestion, blocking, QoS

prioritization and multiple signal paths with

varying latency which can lead to jitter, lost

packets, duplicate packets, and out of sequence

packet delivery.

Use the CES8 to deliver Private line T1/E1

services, subtend a channel bank for derived

2W/4W legacy special circuits or for Business

LAN services. Whatever the application,

Service Provider SLAs will be honored when

deployed with Ethernet Protection Switched

Ring (EPSR) network topology. Expect five 9's

(99.999%) reliability of SONET, but with the

simplicity, efficiency and cost savings of Ethernet.

Allied Telesis

Part of Allied Telesis' IP Broadband

Access Family

Whether it is broadband ADSL2+, FTTH or

T1/E1 circuits, the iMAP family is the ideal

platform for last mile service delivery.The CES8

line card can be used with any of the iMAP

family of carrier grade, IP Access platforms:

•

iMAP 9700 (9RU, 17 service slots)

•

iMAP 9400 (3RU, 7 service slots)

•

MiniMAP 9100 (1RU, 3 service slots)

Provisioning, management, and diagnostics of

subscriber ports can be accomplished from

either the iMAP command line interface or the

NMS.

The CES8 has been designed to survive the

most rugged environmental conditions. It can be

confidently deployed in either a central office or

in outdoor enclosures withstanding extremes of

heat, cold, and light exposure.
