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.
Key Features
• 8 T1/E1 ports
• Pseudo-wire compliant to the SAToIP standard
• T1 reach is selectable for short haul DSX-1
or long haul T1
• Integrated jitter buffers absorb packet network
delay variation
• Provides Layer 2 services using existing
E1/T1 circuits
