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

t subscriber module is ideal for delivery of

por converged POTS and DSL ser vices 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 por ts will carry converged POTS,VoIP and Data traffic - either collectively or individuall individual T1/E1 ports on the NTE8 module, the remaining MLPPP bundled circuits will continue to carry network traffic.

Pr Connectivity

The secondar 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

age the same last mile access infrastructure

lev used to deliver residential services to delivery T1/E1 services.

Business router 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.
