Health and Status
Health and Status (H/S) enables you to display the
status of the DSU, as well as a DBM, TDM or MCMP, if
installed. It automatically scans for DSU and line
conditions that are not within normal limits.
There are three types of Health and Status reports:
• Devic (Device Health and Status) – displays the
health and status for a local or remote DSU (and
DBM and TDM or MCMP, if installed).
• Expan (Expanded Health and Status) – only
appears during automatic dialing, retrieving the
local DSU’s health and status information when
there is a failed dialing attempt or an unsolicited
disconnect after a successful connection.
• Subn (Subnetwork Health and Status) – displays
status information from a DSU’s subnetwork (all
DSUs and DBMs assigned to that DSU’s active poll
list). The downstream network addresses and
current statuses are listed.
For a complete list of Health and Status messages, refer
to Appendix C of the COMSPHERE 3600 Series Data
Service Units, Models 3610 and 3611, Operator’s Guide.
Device Health and Status
The Device Health and Status (Devic) selection reports
health and status information for a selected DSU.
NOTE
If five minutes elapse without a
key being pressed, the Device
Health and Status screen is
redisplayed.
To access Device Health and Status from the top-level
menu, make the following selections:
• Local (F1), or Remot (F2) and Address
• Stat
• H/S
• Devic
Results
When the digital circuit is the active link, the first line
displays a running normal-operation timer (hhh:mm:ss).
The second line displays the DSU’s operating rate and can
also display one or more of the test or alarm messages
listed in Appendix C of the COMSPHERE 3600 Series
Data Service Units, Models 3610 and 3611, Operator’s
Guide. An asterisk ( * ) appears at the far right to indicate
NMS activity. A right arrow ( → ) appears just before the
asterisk if there is more than one existing message.
For a DSU with TDM or MCMP, the Device Health
and Status of the TDM or MCMP is incorporated into the
health and status of the DSU, along with any test or alarm
involving the TDM or MCMP. In the example below,
Port 3 has been in DTE Loopback for 2 hours, 3 minutes,
and 21 seconds. The DTE Loopback originated from the
DCP (DTE, FP).
