No Dial Tone, BUSY lamp OFF (E&M/E&M-OD)
Symptom
:
No dial tone is heard when grabbing the E&M trunk form the
PBX. The unit’s BUSY lamp is OFF.
Cause
: The
unit’s TERMDLD and PBX trunk parameters are incorrectly
configured and the E&M cabling may be incorrect.
Action
:
Refer to the installation instruction and check the TERMDLD and
PBX trunk parameters. See BV1250 Installation Guide, Section
5.9, for details.
If the problem persists, check the E&M cabling to verify that it
conforms to the installation instructions. See BV1250 Installation
Guide, Section 4.5, for details.
Connected Call Dropped (E&M/E&M-OD)
Symptom
:
When calling a remote unit, the call is connected but is dropped
within couple of seconds.
Cause
:
It is likely that the unit and PBX trunk parameters are in conflict.
For example, the unit is configured for Immediate-start but the
PBX trunk is configured for Delayed start.
Action
:
Refer to the installation instructions for configuring E&M trunk
parameters and correct conflicts between the PBX parameters
(TERMDLD) and the unit’s trunk parameters. See BV1250
Installation Guide, Section 5.9.1, for details.
Unable to connect through PBX Type 1 (E&M/E&M-OD)
Symptom
:
Call cannot be connected with a unit that is connected through a
PBX using Type 1 start-up.
Cause
:
It is likely that the BV1250 base unit and the PBX using Type 1
start-up have not been installed so that they share a common
ground.
Action
:
When installing a unit for use with a PBX Type 1 E&M interface
the BV1250 unit and the PBX must be connected to a common
ground. Refer to the installation instructions to install the ground
properly. See BV1250 Installation Guide, Section 4.5, for details.
