ARCSmart

2.1 Intelligent Network Management

Arcwave’s ARCSmart intelligent network management combines an embedded DOCSIS 2.0

compliant cable modem, SNMP-compliant Arcwave Enterprise MIB R2.1 (management

information base), and an upgradeable processing engine with upgradeable software to support

low cost configuration, monitoring, and troubleshooting of an ARCXtend Network Hub (Hub).

Specific capabilities include:

• DOCSIS 2.0-compliant embedded cable modem (ECM)

• SNMP-compliant Arcwave Enterprise MIB

• HTTP-based User Interface

• ARCSmart firmware upgrade

DOCSIS 2.0 Compliant ECM

Each Hub includes a hardened DOCSIS 2.0-compliant cable modem (ECM) supporting in-band

communication over standard DOCSIS channels with ARCSmart. For proper operation of

ARCSmart Advanced Network Features the ECM and all cable modems served by the Hub

must be on the same downstream and upstream DOCSIS channels at all times.

The ECM firmware can be upgrading using TFTP and normal cable modem firmware upgrade

procedures.

Watchdog Timer

This embedded cable modem also includes a system watchdog timer with a peripheral bus

interface. It provides a method for resetting the host, upon expiration of the timer value, to heal

system hangs due to software bugs, power spikes, and so on. The watchdog timer period and

pre-scale values are programmable and are protected by dual keyed-lock state machines.

Disabling of the watchdog timer is protected by both hardware tie-offs and a triple keyed-lock

state machine. Resetting (kicking) of the watchdog timer is provided through a dual keyed-lock

state machine.
