The switch has the ability to do intelligent call routing between BRI ports and through the PRI trunk down to the BRI ports and back out if you wish, it does DID both ways and preserves CNAM/CNUM. The T1/PRI upstream link can connect to a real telco DACS (Digital Access Cross-connect System) or to your own lab equipment. The BRI interfaces are programmable for  AT&T 5ESS, , DMS100, NT1  .              This unit is guaranteed to work. It comes with the management/configuration cable     Here is some infromation from Adtarn :   ATLAS 550 GIVES INSTRUCTORS THEIR OWN CENTRAL OFFICE. The ATLAS 550 Integrated Access Device has been chosen by the Cisco Networking Academy to emulate WAN services including Frame Relay, ISDN, Euro-ISDN, and Analog (POTS) for both the Cisco Certified Networking Associate (CCNA) and Cisco Certified Networking Professional (CCNP) programs. The ATLAS 550 will emulate Central Office delivery of WAN services, allowing students to get real-world experience in configuring complex networks.      "Required" equipment for CCNP Academies.      Unit being sold has  2 T1 cards installed  .   Bid with confidence, it's a great Switch. Buyer to pay  shipping in Continental 48 US States (Ground shipping, Insured).  Will ship to other countries but shipping will be much greater. Apporx.  $170 to Europe and  Far East.    ATT 5ESS NI-1   ( National ISDN ) DMS-100 4ESS  (PRI) EuroISDN (PRI) This switch is an excellent Simulator for a  Lab or Classroom setup. One of the most configurable units as far as which phone numbers and SPID's can be input into the configuration.           Information From the Adtran Manual :   FEATURES AND BENEFITS The following is a brief list of ATLAS 550 features and benefits: Configuration and Management • VT100 Emulation • SNMP, per MIB II (RFC1213), DS1/E1 MIB (RFC1406), Frame Relay MIB (RFC1315), and ADTRAN private MIBs • Telnet • Dial up remote management via optional Modem Management Network Module (P/N 1200341L1) • Six levels of password protection and privileges Software Upgradeable • Flash memory • TFTP download • XMODEM via control port 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 ATLAS 550 System Manual Section 1, System Description 61200305L1-1F © 2002 ADTRAN, Inc. 17 ISDN Switch Types • 5ESS™, DMS-100™, National ISDN, 4ESS™, EuroISDN Dedicated Connection Maps • Up to five connection maps • Time of day/day of week configurable • Preserves signaling through cross-connect • No effect on non-configured 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 a public frame relay network, a private frame relay network, or a point-to-point (PPP) network and the Ethernet port. • 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 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 1200312Lx.) • Performs voice packetization (G.711 or Transparent) or voice compression/decompression (G.726) and interfaces to either a Private Branch Exchange (PBX) or the PSTN. (This feature 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.
