DBM Configuration Options
Call Setup:None
Next None Pswrd Cllbk Alarm Prev
Dial Backup Call Setup
. Establishes the security level on call setup attempts. The Password and Callback security
selections use a proprietary password exchange to ensure that the DBM does not route line data to the DBM’s DTE
interface. If security fails, the call is disconnected. These password exchanges only work between 3600 Series DBMs.
None — No security. Outgoing calls have no security. For incoming calls, if the calling device is not a 3600 Series
DBM, an answering DBM with Call Setup set to None will automatically switch from Standby to Dial
Backup mode after the time-out period has expired.
Pswrd — Intermediate security level. The originating and answering DBMs must exchange valid passwords to
establish a call.
Cllbk — Highest security level. The originating and answering DBMs exchange passwords and disconnect; the
answering DBM calls the originator back with a second exchange of passwords.
Alarm — Causes a DBM to answer incoming calls only when the DSU reports a Facility Alarm. No security
checking is performed. This feature is for customers that provide data services to other customers that
may not have non-3600 Series DBMs.
RxPwd:
Next Chang Prev
Receive Password
.
The password that the DBM expects to receive from a remote DBM (must be the same as the
remote DBM’s TxPwd). The maximum password length is 10 characters. The default, *, is a wildcard meaning “any
character string.”
When Call Setup is set to None or Alarm, this configuration option will not appear
.
Chang — Enter up to 10 characters for the receive password. An underscore ( _ ) to the immediate right of the last
password character is required for passwords of fewer than 10 characters in length. To make the
password invisible to the DCP, enter a comma ( , ) as the first character.
TxPwd:
Next Chang Prev
Transmit Password
. The password that the DBM sends to a remote DBM (must be the same as the remote DBM’s
RxPwd). The maximum password length is 10 characters. The default is a null password.
When Call Setup is set to
None or Alarm, this configuration option will not appear
.
Chang — Enter up to 10 characters for the receive password. An underscore ( _ ) to the immediate right of the last
password character is required for passwords of fewer than 10 characters in length. To make the
password invisible to the DCP, enter a comma ( , ) as the first character.
Dial Test:Disab
Next Enab Disab Prev
Dial Test
. When enabled, the DBM periodically checks for a signal or dial tone. If the test fails, the DSU reports a Dial
Test Failure alarm in its health and status. A Dial Test occurs once every 60 minutes until a failure occurs. Then, the test
repeats every minute until the network recovers.
If enabled, the V
.32 DBM periodically tests receipt of dial tone, the 4-wire Switched 56 DBM goes off-hook and checks
for receipt of a data mode idle (DMI) signal burst (referred to as
winkback detection
), and the 2-wire Switched 56 DBM
goes off-hook and checks for receipt of a proceed-to-select message from the switch.
Enab — Enables the Dial Test.
Disab — Disables the Dial Test.
