ATLAS 550 System Manual Section 1 System Description
Dedicated Connection Maps
• Up to five connection maps
• Time of day and day of week configurable
• Preserves signaling through cross-connect
• No effect on nonconfigured channels
Switched Connection Maps
• Inbound and outbound call filtering and blocking
Testing
• Local and remote: payload/line, V.54 (depending on installed modules)
• Patterns: 511, QRSS, all ones, all zeros (depending on installed modules)
Performance Monitoring
• Reports: Information stored for last 24 hours in 15-minute increments
• Performance statistics per TR54016, T1.403, RFC1406
• Alarm reporting per TR54016, T1.403
Frame Relay
• Routes Internet Protocol (IP) traffic between the Ethernet port and a public frame relay network, a
private frame relay network, or a point-to-point network
• Concentrates IP traffic from a public or private frame relay network and passes frame relay data with
RFC 1490 encapsulation to one or more serial ports (V.35)
• Passes Systems Network Architecture (SNA), Bisync, and other legacy protocols between a public or
private frame relay network and an external DTE running Frame Relay to the ATLAS 550
• Performs voice compression/decompression (G.723.1) and interfaces to either a Private Branch
Exchange (PBX) or the Public Switched Telephone Network (PSTN) (requires an additional option
module, the VCOM Module—P/N 1200312Lx)
• Performs voice packetization (G.711 or Transparent) or voice compression/decompression (G.726) and
interfaces to either a PBX or the PSTN (requires an additional option module, the 32-Channel ADPCM
Resource Module—P/N 1200752L1)
• Supports LMI, Annex D, or Annex A signaling on frame relay connections
PPP Switching
• Supports up to 100 simultaneous PPP connections
• Performs PAP, CHAP, or EAP authentication methods on a per-connection basis
• Includes keepalive functionality for PPP connections
• Provides capability for numbered or unnumbered PPP interfaces
