Key Features  
8T1/E1 ports  
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 secondary application that is supported by  
the NTE8 service module is providing last mile  
access to small and medium sized businesses  
utilizingT1/E1 PPP uplinks. As last mile access  
continues to evolve, Service Providers can  
leverage the same last mile access infrastructure  
used to deliver residential services to delivery  
T1/E1 services.  
Support for MLPPP Encapsulation  
Network WAN Connectivity Between iMAPs  
Business CPE Support  
Support for Multiple Remote Locations  
The NetworkTerminating Equipment (NTE8) 8  
port subscriber module is ideal for delivery of  
converged POTS and DSL services to remote  
locations. Using MLPPP as a bonding  
Business routers employing PPP overT1/E1  
WAN uplinks can use the NTE8 to terminate  
data circuits and transport traffic over standard  
VLAN circuits throughout the last mile

QoS  
technology, one to 8 ports can be bonded  
together to deliver up to 16Mbps of bandwidth  
to remote locations fed by traditionalT1/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  
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

individually. If port or network outages disable  
individualT1/E1 ports on the NTE8 module,  
the remaining MLPPP bundled circuits will  
continue to carry network traffic.  
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 service delivery.The NTE8 line card  
can be used with any of the iMAP family of  
carrier grade, IP Multiservice Access platforms:  
The NTE8 service 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 service carryingVLANs for proper traffic  
segmentation and classification.  
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 AT-TN125 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.
