Bank Controller Unit (1200373L1 and 1200373L2)
The following is operational information pertaining to the Bank Controller Unit when used with the
Total Access 850 system.
Faceplate LEDs
The faceplate Network LEDs labeled
T1 NETWORK
and
T1 FRACTIONAL
provide status information
using a color coded message format. Table 1 gives a description of all faceplate LEDs for the BCU when
used with the Total Access 850 system.
DIP-Switch Settings
The Total Access 850 BCU can be provisioned from DIP-switches (S1) mounted on the PCB, or through
screen menus accessed via the faceplate
ADMIN
interface. Basic T1 provisioning, clock source, and CSU
loopback options are found on the DIP-switch panel. Table 2 gives DIP-switch provisioning information.
DIP-switch S1 must be provisioned without the BCU in the chassis. Once the BCU is installed, any software
provisioning made will override the DIP-switch settings. If the BCU is withdrawn and reinserted
(power-cycled), the software options remain in effect. If a DIP-switch setting is changed while the BCU is
withdrawn, the new DIP-switch setting takes effect. If none of the DIP-switch settings were changed, the
unit will be provisioned for the last software settings.
Table 1. BCU Faceplate LEDs
For these LEDs...
This color light...
Indicates that...
Network/Frac T1
OFF
there is no power to the system.
RED
the unit is in Red Alarm (meaning the T1 is down, not
connected, or framing is improperly configured).
YELLOW
the unit is receiving Yellow Alarm (meaning the far end
unit is in Red Alarm).
Solid GREEN
the unit is functioning normally.
Blinking GREEN
the network T1 interface is in Test mode.
