ADTRAN 1200305L1 Isdn Switch Types, Dedicated Connection Maps, Switched Connection Maps, Testing

ATLAS 550 System Manual Section 1, System Description

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 net- work, 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 Ex- change (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.
