Cabletron Systems CSX100 series User Manual - Dial-On-Demand

ISDN Router

Dial-on-Demand

Dial-up WAN resources are accessed only when remote access is required and

released as soon as the resource is no longer needed.

Bandwidth-on-Demand

The router can optimize the use of WAN resources (i.e., two ISDN B-

channels) to increase throughput, depending on load requirements.  Two

ISDN B-channels can be “bundled” to permit transmission of data traffic over

both channels after a link utilization threshold is reached.  The second

channel is released when utilization falls below the threshold.  Support

includes both routing and bridging applications.  Bandwidth-on-Demand

management can occur on incoming, outgoing, or both directions.  The

Multi-Link Protocol for PPP (MLP) is used to implement this feature.

Split B-Channels

Each 64Kbps ISDN B-channel can be used individually for a separate data

connection.

POTS Analog Line Interface

The router software support for local analog phone devices provides

emulation of central office voice services to control the analog lines.  Call

progress tones and DTMF are supported.  Only one line can dial at a time; the

other line can have an established call in progress while the second line is

dialing.

Simple Network Management Protocol (SNMP)

The router provides SNMP agent support and support for standard as well as

Enterprise Specific MIBs.  SNMP is also used internally for configuration of

the router.  The active SNMP agent within the router accepts SNMP requests

for status, statistics, and configuration updates.  Communication with the

SNMP agent occurs over the LAN or WAN connection.  Any management

application using SNMP over UDP/IP (User Datagram Protocol/Internet

Protocol) has access to the local SNMP agent.
