System Description
XSR Getting Started Guide 1-7
• Periodic Keep-Alive messages to learn of connection problems
• Multi-protocol interconnect over Frame Relay - RFC-2427
• RFC-2390 Frame Relay Inverse ARP to discover IP address of remote peer when used in multi-
point mode and responds to incoming Inverse ARP requests independent of P2P or MP2P
• Multiple logical interfaces over the same physical Frame Relay port: sub-interfaces
• Quality of Service: standard FIFO queuing, or IP QoS on DLCIs.
• Max PDU size of 1600 bytes
• Traffic shaping
• Frame Relay Fragmentation Implementation Agreement (FRF.12)
• Data Communications Equipment (DCE) support
• Frame Relay over ISDN
• Remote Auto Install over Frame Relay
Dynamic Host Configuration Protocol (DHCP)
• Temporary or permanent network (IP) address allocation to clients
• Network configuration parameter assignment to clients
• Persistent storage/database of network values for network clients - Bindings Database
• Persistent storage of network client lease states kept across reboot
• Persistent and user-controllable conflict avoidance to prevent duplicate IP address including
configurable ping checking
• Visibility of DHCP network activity and leases through operator reports statistics and logs
• DHCP Client
Integrated Services Digital Network (ISDN) - BRI/PRI
• Circuit Mode Data (CMD): Channels (DS0s) are switched by the CO to the destination user for
the duration of the call
• Outgoing calls supported for Backup, DoD/BoD
• Incoming calls routed to the correct protocol stack based on called number/sub-address and
calling number/sub-address
• Permanent B-channel support, i.e. 64 or 128 kbps lease line. Each BRI port can be set for CMD
or Leased-Line mode of operation
• BRI supported switches: ETSI
• BRI: TEI auto-negotiated
• Q.921/Q.931 (Layer 2/Layer 3) configuration is set automatically by selection of switch type
• PRI supported switches: ETSI, NI, DMS100, NTT
• PRI: Handling restart and maintenance modes automatically set
• PRI: Fixed TEI to 0
• ISDN switched and Leased Line connections
