The AOLT-4000N is designed for carrier central office or MSO hub environments for enabling costeffective FTTx services.
Two control card slots for 1+1 CTL cards. Two switch and timing slots for 1+1 SWT cards with redundant 10-GbE and 1-GbE Service Node Interfaces (SNI) uplinks. Ten line card slots for 10 GLCP cards.
Data Plane Connectivity
TThe AOLT-4000N's data plane consists of redundant 10Gbps connections to each card slot from the two dedicated double-width SWT slots in the shelf.
Control Plane Connectivity
The AOLT-4000N's control plane consists of redundant 1Gbps connections to each card slot from the two dedicated CTL slots.
Inputs for redundant BITS/SSU timing interfaces for GPON and TDM synchronization and outputs for sourcing clocks for external synchronization use.
Dual star redundant architecture with 20 Gbps bandwidth to each card slot and 400 Gbps bandwidth total capacity.
High availability architecture where removal or insertion of any single card does not affect existing connections on other cards. Even in a system with a single CTL card, a failure of the control card does not affect the working traffic. To increase control plane availability, a second mate CTL card can be inserted in the AOLT-4000N chassis, providing 1+1 redundancy for the control plane. Likewise to increase data plane availability, a second mate SWT card can be inserted in the AOLT-4000N chassis, providing 1+1 redundancy for the data and signaling plane.
AEMS or SNMP Managed
With the CTL card installed, AOLT-4000N is either remotely or locally managed from either Alphion's Element Management System (AEMS) or with a 3rd party EMS using SNMP or a legacy NMS.
