AT-TN125-A 8 Port T1/E1 MLPPP Service Module
Allied Telesis’ iMAP family of integrated
Multiservice Access Platforms
Bonded
T1/E1 Ports using MLPPP
for Network Backhaul
Remote locations have often been ignored by
Service Providers due to the lack fiber
infrastructure between COs and remote
terminals/locations. As the rest of the last mile
network converges on IP/Ethernet delivery
technologies, these locations need a means to
leverage IP/Ethernet while also offering legacy
POTS and last mile broadband services.
The Network Terminating Equipment (NTE8) 8
por
t subscriber module is ideal for delivery of
converged POTS and DSL services to remote
locations. Using MLPPP as a bonding
technology, one to 8 ports can be bonded
together to deliver up to 16Mbps of bandwidth
to remote locations fed by traditional T1/E1
circuits. Since the NTE8 uses MLPPP as the
bonding protocol for the 8 individual T1/E1
ports, all ports will carry converged POTS,VoIP
and Data traffic - either collectively or
individuall
y. If port or network outages disable
individual T1/E1 ports on the NTE8 module,
the remaining MLPPP bundled circuits will
continue to carry network traffic.
The NTE8 ser
vice module is intended to be
used in any of the iMAP product chassis. In
addition, individual NTE8 modules at a central
location can be used to aggregate traffic from
m
ultiple remote locations.
All tr
aff
ic is mapped
to ser
vice car
rying VLANs for proper traffic
segmentation and classification.

ovide Business Router
Connectivity
The secondar
y application that is supported by
the NTE8 service module is providing last mile
access to small and medium sized businesses
utilizing T1/E1 PPP uplinks. As last mile access
continues to evolve, Service Providers can
lev
er
age the same last mile access infrastructure
used to deliver residential services to delivery
T1/E1 services.
Business router
s employing PPP over T1/E1
WAN uplinks can use the NTE8 to terminate
data circuits and transport traffic over standard
VLAN circuits throughout the last mile
network. Using iMAP elements at a central
location,VLANs can be switched to the
appropriate IP Data network. Leveraging
standards based IP/Ethernet technologies, the
iMAP and NTE8 service modules truly
converge all traffic - residential and business.

Family
Whether it is broadband ADSL2+, FTTH or
POTS, the iMAP family is the ideal platform for
last mile service delivery.The NTE8 line card
can be used with an
y of the iMAP famil
y of
carrier grade, IP Multiservice Access platforms:
• iMAP 9700 (9RU, 17 service slots)
• iMAP 9400 (3RU
,
7 ser
vice slots)
• MiniMAP 9100 (1RU
,
3 ser
vice slots)
Pro
visioning,
management,
and diagnostics of
subscriber ports can be accomplished from
either the iMAP command line interface or the
NMS.
The AT-TN125 has been designed to survive
the most rugged environmental conditions. It
can be conf
identl
y deplo
yed in either a central
office or in outdoor enclosures withstanding
extremes of heat,
cold,
and light exposure
