BavSonic E&M Telephone Audio Features
The BavSonic E&M telephone intercom interface module connects the intercom system of the
drive-thru pharmacy lane to the telephone system. This is a full duplex audio system for
maximum intelligibility. The incoming and outgoing audio levels are adjustable inside the
interface.
The customers at the remote-drive-thru locations can call the pharmacy by depressing the CALL
BUTTON on either lane. This initiates a call to the telephones in the pharmacy that are
programmed to receive them. The pharmacy employees can access each remote lane from the
telephones that are given access. If a customer presses the call button, and the call is not
answered in approximately one minute, the call is terminated for 10 seconds then another attempt
is made. This will happen five times at which point the interface will reset itself awaiting the
next activation of the call button.
Telephone Interface
Power is supplied to the interface through an 110v power cord and is protected by a non-
replaceable 1 amp fuse. The customer will supply the 110v power outlet as well as the
connections from the telephone system to an area under the counter adjacent to the drive-thru
window.
Telephone system requires an E&M port for each lane, and the phone system to be programmed
to connect to the interface. This also is the customer’s responsibility.
These items should be in place, and the phone system programed, before installing the
BavSonicTM E&M Telephone Interface.

Telephone Connections
This system is configured for a “TIE LINE” connection to a Nortel/Avaya telephone system.
The telephone system is supplied and installed by those other than E.F. Bavis and Associates.
There will be an E&M Tie Line Card in the telephone system, which is located in the electrical
equipment room. The connections to the telephone use standard CAT 5 wiring. The termination
is a type 568B. The connectors are RJ45. The E&M connections to the Nortel/Avaya system are
referenced to the system ground and system battery. These reference levels are included in the
RJ45 connection
In the programming for the “TIE LINES” the following settings are required by the BavSonic
system. Line type = E&M, Answer = Manual, Answer DISA = NO, Signal = IMMEDIATE,
Gain = NORMAL, Dial Mode = TONE.
Telephone Diagnostics
The WHITE /GREEN STRIPE (E1) wire is referenced to the GREEN (E2) wire. The normal
voltage is 56Vdc with the BROWN wire being positive. After the call button is depressed the
voltage will be less than 1Vdc. This indicates that the intercom is connected to the interface.
This is the “E Lead” sensing. There is a LED for each lane to indicate that the intercom is
connected to the interface.
The BROWN (M1) wire is referenced to the WHITE/BROWN STRIPE (M2) wire. The normal
voltage is 5Vdc with the BROWN wire being negative. The voltage is less than 1Vdc when the
telephone is connected to the interface. This is the “M Lead” sensing. There is a LED for each
lane to indicate that the telephone is connected to the interface.
The BLUE, WHITE/BLUE STRIPE (TRANSMIT) wires are the audio signal coming from the
telephone transmitter going to the intercom speaker. With the lane selected and someone talking
the audio signal is approximately .848Vp-p as measured on an oscilloscope or .3Vrms as
measured on a true rms digital multimeter.
The ORANGE, WHITE/ORANGE STRIPE (RECEIVE) wires are the audio signal coming from
the intercom microphone to the telephone receiver. With the lane selected and someone talking
the audio signal is approximately .848Vp-p as measured on an oscilloscope or .3Vrms as
measured on a true rms digital multimeter.
When connecting to a Cisco phone system, the E&M Telephone Interface system requires one
(1) Transfer or A/B Cat5 patch cable. This cable can be at either at the Interface box or at the
phone server. If there not a Transfer cable, or if there are two cables, the symptom would be that
as soon as the Cat5 cable is connected to the Interface box and the phone server, the phone server
will react as though the call button has been pressed, and/or the line is “Busy”.

Intercom Connections
Note: If there is a separate Incoming Volume Control assembly installed onto the old system,
that Volume Control assembly must be removed.
There is an intercom board (base audio board) located at each of the drive-thru lanes. Note that
the base audio must be calibrated for BEAM use. There will be a label on the base audio board
specifying beam calibration. This board is connected to the telephone interface via standard
CAT 5 wiring. Remote lanes have a Microfit connector for improved weather resistance. First
lanes use a RJ45 plug which is terminated 568B. Each remote intercom board has a LED, which
indicates that it is receiving power. The audio level adjustments on the base audio board are
sealed after they are calibrated. The audio levels are adjusted inside of the interface.
The intercom audio board for the 64” All-In-One window with the E.F. Bavis counter system is
attached to the black laminated or Stainless Steel filler panel under the transaction drawer. For
other window/drawer installations, it will be inside of a 2-1/8” x 3-1/4” x 5-1/4”, Stainless Steel
enclosure. The intercom audio board for the TransTrax is located inside a weatherproof
enclosure, on the customer speaker panel, of the customer unit located on the outside island.
The base audio component connections are as follows: Plug J1 is for the speaker connection.
The connector is a 3-position with positions 1 & 3 being the speaker. For the outside board, plug
J2 is an 8-position Microfit, for the inside board, plug J2 is an 8-position RJ45. Plug J3 is for the
call button connections. The connector is a 4-position with positions 2 & 3 being the button.
Note that positions 1 & 4 are 19vdc power with position 4 being positive. Plug J4 is for the
microphone connection. This connector is a 2-position.
Please see page 11 for an overall wiring diagram of the intercom section.
It is recommended to install the RJ45 connector directly onto the end of the CAT5 cable for the
drive-thru lane. For situations where tooling is not available to attach the RJ45 to the end of the
CAT5 cable for the remote lane(s), we have included a Cat5 Audio Connection Kit, (P/N
22316991) that can be added onto the cable for plug-in connection capability.
