Page 54 Enabling/Disabling the Internal Modem
Networked systems containing nodes running Inter-Tel Axxess v8.1 or earlier require special
attention because those nodes do not have the Alarm Queue feature.
In networks that include these early-version Axxess systems, a broadcast message is sent only
when the most recent network alarm is cleared. When the message is sent, that network alarm
is cleared on all nodes in the system. Once the alarm is cleared, Axxess v8.1 or earlier nodes
will not show any other alarms because they do not have a queue to store alarms.
Nodes that are running v8.2 and later, however, may still have additional alarms in the queue.
When this happens, each v8.2-and-later node must manually clear the other network alarms.
For example, imagine a three-node network with Node 1 running Axxess v8.0, Node 2 running
Axxess v9.0, and Node 3 running Inter-Tel 5000 v1.1. The following sequence of events could
possibly occur:
• Node 1 generates two network alarms, one immediately after the other. However, Node
1 shows only the second alarm because it has no ability to queue alarms. Nodes 2 and 3
show both network alarms.
• Node 1 clears the second alarm—the only one it can recognize—and a broadcast mes-
sage is sent to the other nodes. Node 1 now shows no alarms, but Nodes 2 and 3 still
show the first alarm.
• Node 2 then clears the first alarm, but a broadcast message is NOT sent.
• Now, Nodes 1 and 2 show no alarms, but Node 3 still has one in its alarm queue. This
alarm will stay in the queue until Node 3 clears it or until the alarm is overwritten as a
repetitive alarm.
Enabling/Disabling the Internal Modem
Inter-Tel CS-5200/5400 internal modem performs multiple functions. When enabled, the
modem is for Database Programming, Message Print, SMDR, and for uploading software
licenses.
If disabled, the modem and extension is placed into DND. In DND, the modem rejects all calls
and does not allow camp ons. Any outside calls that attempt to ring a disabled modem are
automatically transferred to the Primary Attendant.
To enable/disable a modem:
1. While on-hook, enter the Modem Enable (9866) or Modem Disable (9867) feature
code. The display shows ENABLE (DISABLE) MODEM EXT #.
2. Enter the extension of the modem to enable/disable it. The display shows MODEM
ENABLED (or DISABLED).
If an invalid modem extension is entered, the display shows INVALID MODEM
EXTENSION.
Resetting the Internal Modem
The internal modem must be reset if it fails to answer an incoming call or is out of sync with
an external modem.
CAUTION
Possible data corruption. Do not reset the modem if it is connected to a Database
Programming session. If you do, the programming session is dropped, potentially corrupting
the database. For this reason, Inter-Tel recommends that you assign the modem extension
to a Speed Dial button.
