Features/functions
The IP-AFM LPI960
• acts as a multiplexer between a Gigabit Ethernet Interface and ADSL APs, converting ATM cells into Ethernet packets and vice-versa
• supports four Gigabit Ethernet ports on the faceplate:
– one port is used as uplink to the IP network or in case of a daisy-chain as uplink to the host IP-AFM or the previous IP-AFM in a preceding shelf in the daisy-chain
– one port is used to connect two IP-AFMs in duplex operation
– one port is used as downlink to the next IP-AFM in a succeeding shelf in case of a daisy-chain
– one port is reserved for future use
• supports two Fast Ethernet ports on the faceplate which can be used – as uplink to the IP network
– or to aggregate traffic from any other IP pack (for example ICAP) to the Gigabit Ethernet uplink on the IP-AFM
• provides external RS-232 interface for local console OAM&P port
• provides external 10Base-T interface for local or remote management
• supports simplex or duplex operation; duplex operation provides increased reliability
• supports local and remote software download capability for software upgrades
• supports daisychaining between AnyMedia®Access Systems populated with IP-AFMs over one of the Gigabit Ethernet ports to increase the utilization of the ATM traffic to the IP network
• supports configuration backup and database restoration
• interworks with the COMDAC (if equipped) via UART link for inventory and status to create a complete and consistent view of the shelf on the GSI.

Description
The IP-AFM is a controller pack used in AnyMedia® LAG Shelves and in AnyMedia FAST Shelves to convert ATM xDSL traffic into IP traffic and vice versa. The IP-AFM implements a layer 2 bridge system where the subscriber ATM traffic is interworked into Ethernet frames in the upstream direction. In the downstream direction, the

Ethernet frames are segmented in ATM cells and transmitted to the subscriber side. The ADSL portion of the IP-AFM is identical to the legacy AFM packs. It supports all the xDSL APs which are supported by the AFMs.
Compatibility
There are no compatibility issues.
