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 NetworkTerminating Equipment (NTE8) 8

portsubscriber 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 secondaryapplication 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 routersemploying PPP over T1/E1

WAN uplinks can use the NTE8 to terminate

data circuits and transporttraffic 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.

Partof 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 anyof the iMAP familyof

carrier grade, IP Multiservice Access platforms:

•iMAP 9700 (9RU, 17 service slots)

•iMAP 9400 (3RU,7service slots)

•MiniMAP 9100 (1RU,3service 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 confidentlydeployed in either a central

office or in outdoor enclosures withstanding

extremes of heat, cold, and light exposure.
