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

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 port 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 individually. 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 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 carrying VLANs for proper traffic segmentation and classification.

Provide Business Router

Connectivity

The secondary 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 leverage the same last mile access infrastructure used to deliver residential services to delivery T1/E1 services.

Business routers 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.

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:

•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.
