“Almost Full” Audible Alarm
The CRB unit can be set up to emit a beeping tone when its memory is 80% full. The
tone’s intensity increases as more memory is used.
Light-Emitting Diode (LED) Indicators
There are four light-emitting diode (LED) indicators on the top of the CRB unit as shown
in the diagram on the next page. The LEDs are used to indicate the following information:
·
ON:This LED lights when the unit is receiving AC power. The power connector and
power switch are located on the PBX end of the unit.
·
MEM:The flash rate of this LED indicates approximately how much memory is cur-
rently being used. When the memory is empty, the LED is unlit. When the memory is
between 0% and 10% full, the LED flashes once before pausing. When the memory
exceeds 10%, the LED flashes twice up to 20% full, three times up to 30% full, and so
on. For example, if the memory is 43% full, the LED flashes five times, then pauses for
a second before flashing five times again. If the memory is full (100%), the LED is
solidly lit.
On GMX-48, GX-120, GMX-152D, IMX 2448, IMX 1224/2460, and ESPtelephone
systems, this LED may flash once even though the memory is actually empty.
·
PBX:This LED flashes whenever the unit is receiving information from your tele-
phone system (even if the buffer box is turned off). This allows you to verify that the
unit is properly connected to the telephone system and that call records are being trans-
ferred. If this LED is continually lit, it may indicate a cable or telephone system port
problem.
·
PAUSE:This LED lights whenever the data transfer process has been temporarily
suspended for some reason, such as: the unit receives an X-OFF command, the unit
receives a low DTR signal, X-ON/X-OFF handshaking is disabled, or thePAUSE but-
ton on the top of the unit is pressed.
DIP Switches
The DIP switches on the bottom of the CRB unit are used to select the bit rate, audible
alarm option, data compression scheme (including parity type and bit rate), X-ON/X-OFF
option, and X-ON single call record mode. Refer to the manufacture’s manual for detailed
information.
There are two independent bit rate settings on the CRB unit, one for the connection to the
telephone system and one for the connection to your PC (or an external modem). The unit
can communicate with the telephone system at 300, 1200, 2400, or 9600 bps. It can com-
municate with your PC at 9600, 19200, 38400, or 115200 bps.

AXXESSORY Talk PC and Axxent Talk
If you have an Inter-Tel AXXESS or Axxenttelephone system equipped with an optional
AXXESSORYTalk PC an Axxent Talk (respectively), you can use theAXXESSORY
Talk PC or the Axxent Talk hard disk instead of a buffer box to storeSMDRcall records.
The call records are then transferred from theAXXESSORYTalk PC or the Axxent Talk
hard disk to your PC.
To do this, the“SMDR Buffering” application must be enabled through the telephone
system’s database programming. Every time a call is completed, theAXXESS or the Ax-
xent SMDR feature will record the call, format it according toSMDR programming, and
send the record to the AXXESSORYTalk PC or the Axxent Talk hard disk.
The amount of disk space allocated forSMDR storage is determined in the telephone
system’s database programming. The default value is zero megabytes of memory. If the
call records use disk space exceeding 80% of the allotment, the telephone system gener-
ates an alarm and displays it at the primary attendant station and at all administrator sta-
tions. Another alarm message is generated if the allotted space is 100% filled. If the maxi-
mum buffer capacity is exceeded, the oldest call record(s) are discarded as new ones
arrive.
Since eachSMDRcall record takes up approximately 81 bytes on theAXXESSORYTalk
PC, nearly 13,000 calls can be stored in each megabyte of hard disk space.
Refer page 47 for instructions on connecting your PC to theAXXESSORYTalk PC to
retrieve the SMDR data.
You can also buffer call records to theAXXESSORYTalk or Axxent Talk and send call
records to a serial port simultaneously.
Communications Parameters
To communicate properly with theAXXESSORYTalk PC or the Axxent Talk, your PC
must be configured with the following parameters:
·
The communications port bit rate is set to match theAXXESSORYTalk PC or the
Axxent Talk’s output port (see the paragraph on the next page)
·
The data format is 7 bit standard ASCII
·
Parity is even
·
Communication is full duplex

There is one stop bit
Using the SMDR Buffer Programming window in the telephone system’s database pro-
gramming, the output port (COM2) on theAXXESSORYTalk PC or the Axxent Talk
must be set to the same bit rate as the selected communications port on your PC. The
available bit rates are 300, 1200, 2400, 4800, 9600, and 19200 bps (19200 is only avail-
able on the AXXESSORYTalk PC).

RS-232 Connectors
NOTE:RS-232 has undergone several revisions over the last 30 years. The most current
version of RS-232 is EIA/TIA-232-E (July 1991), which includes the alternate use of RTS
and CTS as character-by-character hardware flow control signals. The Inter-TelAXXESS
serial ports conform to RTS/CTS flow control per EIA/TIA-232-E. Older versions of
RS-232, such as EIA-232-D (1987) and RS-232-C (1969) are a subset of EIA/TIA-232-E.
Hence, serial ports which conform to EIA/TIA-232-E are compatible with all RS-232-C
serial ports. However, if the RS-232-C serial port does not support RTS/CTS flow control,
then the connection cannot use RTS/CTS hardware flow control. Refer toAPPENDIX C
— RS-232 AND AXXESS in the Issue 5 Inter-Tel AXXESS Installation and Field Main-
tenance Manual for more information.
When connecting two devices using an RS-232 interface, as shown below, you can use the
guidelines described on the following pages to make the connection. For pinout informa-
tion, refer to pages 25 through 31.
Devices that use RS-232 interfaces:
·
Telephone System (e.g.,AXXESS, Axxent,etc.)
(Includes PCDPMs for AXXESS and Axxent)
·
PC
·
Buffer Box (e.g., PollCat, ILB, or CRB)
·

Guidelines for Making an RS-232 Connection
NOTE:For purposes of this discussion, all pin numbers assume a DB25 connector (which
is the standard RS-232 connector) unless otherwise stated.
When making an RS-232 connection, the RS-232 pins can be subdivided into three groups
as listed below:
·
Data pins (TD and RD)— required
·
Ground pins (Frame ground and Signal ground) — required
·
Control and Status pins (DTR, DSR, RTS, CTS, DCD, and RI) — requirements vary
among manufacturers
You need at least three connections to make a full-duplex RS-232 connection:
·
The two data pins (TD & RD)
·
One ground pin (Signal Ground)
The control and status pins may or may not be necessary, depending upon the RS-232
implementation of each device. The requirements for connecting these pins must be han-
dled on a case-by-case basis.
Data Pins (required)
The rule for connecting data pins is: The “Data Out” of one device always connects to the
“Data In” of another device.
There are two data pins:
DB25RS-232 DescriptionSignal Direction
Pin-2Transmit Data (TD)“Data Out” from a DTE connector; “Data In” to a
DCE connector
Pin-3Receive Data (RD)“Data Out” from a DCE connector; “Data In” to a
DTE connector
RS-232 was designed so that when a DTE connector mates with a DCE connector, a
“straight through” cable can be used. A “straight through” cable is where pin-1 connects
to pin-1, pin-2 connects to pin-2, etc. If you connect a DTE connector to a DCE connector
using a straight through cable, then the Data Out from one device will connect to the Data
In of the other device. 
						

							Chapter 2— Equipment Requirements
22 Inside Track User GuideIn cases where a DTE connector mates with a DTE connector (e.g., a PC-to-PC connec-
tion), or in the case where a DCE connector mates with a DCE connector (e.g., an Axxent
Serial port and a modem), a“2-3 swapper” is needed so that the “Data Out” of one device
always connects to the “Data In” of the other device. A “2-3 swapper” is a simple adapter
that routes pin-2 to pin-3, and pin-3 to pin-2.
What sometimes causes confusion about which pin is “Data Out” and which pin is “Data
In” is the terminology applied to the data pins. Adding to this confusion is the fact that
some manufacturers do not adhere to the RS-232 nomenclature applied to the pins. Some
manufacturers call pin-2 RD and pin-3 TD, which is incorrect. And some manufacturers
do not specify the signal direction or the connector type (DTE vs DCE). Therefore, you
must know which pin is really “Data Out” and which pin is really “Data In” before you can
determine how to connect the data pins between the two connectors.
Ground Pins (required)
The rule for connecting ground pins is: Like ground always connects to like ground.
There are two ground pins:
DB25RS-232 DescriptionSignal Direction
Pin-1Frame Ground (shield)Not intended for carrying current; connect to only one
end of cable, not both ends
Pin-7Signal Ground
(common)Carries current; must connect to both ends of the
cable
In most cases and most RS-232 devices, pin-1 (Frame ground or Shield) is almost never
used (it is not connected to frame ground). It is recommended that it not be used at all
(leave it unconnected). It is also recommended that a shielded RS-232 cable not be used.
Because, if you use a shielded RS-232 cable, the metal shield that surrounds the wires
inside the cable creates a capacitor-like effect. This degrades the RS-232 signals.
If you must use a shielded cable, ideally, the shield in the cable should connect to only one
connector, not both, at pin-1. The purpose of a shield is to reduce or stop EMI from leaving
the cable. If both ends of the shield connect to pin-1 of their respective connectors, then
the shield ends up being a current-carrying ground between the two devices and the shield
becomes an EMI radiator itself instead of an EMI shield.
Pin-7 is the signal common ground, and hence, pin-7 must connect to pin-7.
