BT has named ADVA Optical Networking a supplier of Ethernet last mile access products for its 21st Century Network (21CN). 
ADVA said its equipment will enable BT to provide stringent monitoring from the network core to the customer premise to remotely respond to faults, minimizing the need for manual intervention at customer sites and rapidly increasing their response time. The ADVA Network Manager (NM) will be integrated with BT’s OSS to provide continuous end-to-end service provisioning and monitoring.
ADVA has previously supplied its FSP 500 switch to BT.
