ATLAS 800 Series System Manual Features and Benefits
System Description
Signaling Support
• ISDN D Channel
• Robbed Bit, E&M, Ground Start, Loop Start
• Convert between Robbed Bit Signaling and ISDN D Channel
• Direct Inward Dialing
ISDN Switch Types
• 5ESS™, DMS-100™, National ISDN, 4ESS™, Euro ISDN (ATLAS 830 only)
Dedicated Connection Maps
• Up to five connection maps
• Time of day/day of week configurable
• Preserves signaling through cross-connect
• No effect on unconfigured 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 for the ATLAS is stored for the last 24 hours, last 15 minutes, and last 5 minutes.
• ATLAS 830 can store frame relay performance at user-specified intervals (5, 10, 15, 20, 30 mins).
• 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 (PPP) network.
• Concentrates IP traffic from a public or private frame relay network to one or more serial ports (V.35).
The protocol passed over the serial port is frame relay (RFC 1490 encapsulation).
• 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.
• Performs voice compression/decompression (G.723.1) and interfaces to either a Private Branch
Exchange (PBX) or the Public Switched Telephone Network (PSTN). This feature requires an
additional option module, the VCOM Module—P/N 1200221Lx.
• Supports LMI, Annex D, or Annex A signaling on frame relay connections.
