Home | Alphion | AOLT-4000N ANSI

Applications

The AOLT-4000N is designed for carrier central office or MSO hub environments for enabling costeffective FTTx services.

Flexible Configuration

Two control card slots for 1+1 Control cards. Two switch slots for 1+1 Aggregation switch cards with redundant 10-GbE and 1-GbE Service Node Interfaces (SNI) uplinks. Ten line card slots.

Data Plane Connectivity

The AOLT-4000N's data plane consists of redundant 10-GbE connections to each card slot from the two dedicated double-width AOLT-4000-SWT slots in the shelf. Control Plane Connectivity The AOLT-4000N's control plane consists of redundant 1-GbE connections to each card slot from the two dedicated AOLT-4000-CTL slots.

Synchronization Connections

Inputs for redundant BITS/SSU timing for GPON and TDM synchronization and outputs for sourcing clocks for external synchronization use.

Switch Capacity

Dual star redundant architecture with 20 Gb/s bandwidth to each card slot and 400 Gb/s bandwidth total capacity.

High Availability

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 AOLT-4000-CTL card, a failure of the control card does not affect the working traffic . To increase control plane availability, a second mate AOLT-4000-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 AOLT- 4000-SWT card can be inserted in the AOLT-4000N chassis, providing 1+1 redun- dancy for the data and signaling plane.

AEMS or SNMP Managed

With the AOLT-4000-CTL card installed the 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.
