3. BitStorm 1900 Maintenance
This chapter contains guidelines and checklists for the maintenance of
the BitStorm 1900 system.
Maintenance Guidelines
The following factors can cause service problems in an EtherLoop sys-
tem installation:
• Poor wiring conditions
• Incomplete cable connections
• Improper BitStorm 1900 equipment installation
• Improper data network equipment configuration
• Equipment failure
The following sections briefly describe each of these potential problem
causes.
Wiring Conditions
In general, EtherLoop systems can function well on standard, twisted
pair phone lines (Category 3 or better). However, in older facilities,
extremely poor wiring conditions may exist that can adversely impact
EtherLoop performance, Also, RJ-11 wall jack connectors can become
corroded, which may not impact voice service other than generating
some static on the line, but can interfere with EtherLoop data service.
