AT-TN125-A 8 Port T1/E1 MLPPP Service Module

Multiser vice Access Platforms

Bonded T1/E1 Ports using MLPPP
for Network Backhaul

Remote locations have often been ignored by
Ser vice 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 deliver y
technologies, these locations need a means to
leverage IP/Ethernet while also offering legacy
POTS and last mile broadband ser vices.

The Network Terminating Equipment (NTE8) 8
por t subscriber module is ideal for deliver y of
converged POTS and DSL ser vices to remote
locations. Using MLPPP as a bonding
technology, one to 8 por ts 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
por ts, all por ts will carr y converged POTS, VoIP
and Data traffic - either collectively or
individually. If por t or network outages disable
individual T1/E1 por ts on the NTE8 module,
the remaining MLPPP bundled circuits will
continue to carr y 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
multiple remote locations. All traffic is mapped
to ser vice carr ying VLANs for proper traffic
segmentation and classification.

Provide Business Router
Connectivity

The secondar y application that is suppor ted by
the NTE8 ser vice module is providing last mile
access to small and medium sized businesses
utilizing T1/E1 PPP uplinks. As last mile access
continues to evolve, Ser vice Providers can
leverage the same last mile access infrastructure
used to deliver residential ser vices to deliver y
T1/E1 ser vices.

Business routers employing PPP over T1/E1
WAN uplinks can use the NTE8 to terminate
data circuits and transpor t 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 ser vice modules truly
converge all traffic - residential and business.

Part of a IP Broadband Access
Family

Whether it is broadband ADSL2+, FTTH or
POTS, the iMAP family is the ideal platform for
last mile ser vice deliver y.The NTE8 line card
can be used with any of the iMAP family of
carrier grade, IP Multiser vice Access platforms:

•

iMAP 9700 (9RU, 17 ser vice slots)

•

iMAP 9400 (3RU, 7 ser vice slots)

•

MiniMAP 9100 (1RU, 3 ser vice slots)

Provisioning, management, and diagnostics of
subscriber por ts can be accomplished from
either the iMAP command line interface or the
NMS.

The AT-TN125 has been designed to sur vive
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.
