equipped with a heartbeat LED

The  408M is equipped with a heartbeat LED that  indicates processing  activity  on  the PCB.  (The 408M peripheral processor  is  operating when  the heartbeat LED  is flashing.)  The KSU1 operation LED (located  next  to the power switch) is  tied to the  408M heartbeat LED.   Therefore,  when  the  LED next to the power switch is flashing,  the 408M is active. The  KSU1-408M  has three ribbon cables: •   located at the upper  right and oriented  in a horizontal  position, the J1  cable is used to interface a COM4  if required to expand  the system CO line  capacity. •   located at  the  upper center  and oriented  in  a  vertical position,  the J4  cable  is  used to interface the DX-80 CPM. •   located at the upper  center  and oriented  in a vertical position,  the J5 cable  connects to  the standard APM4 installed  in KSU1. Each CO line circuit  incorporates  over-voltage  protection, ring  detector, loop  detector, loop/pulse-dial relay,  current sink circuit, coupling/isolation transformer (impedance  600:600), hybrid  circuit, CODEC & filter,  polarity guard  circuit  and Radio  Frequency noise filter. The  fourth CO line port is equipped with  CNG Fax  Tone  Detection circuitry.   When  programmed  as  a “FAX” line, this circuit will automatically engage the FAX Tone detector.  If FAX tone is detected, the system routes  the call  to the analog port  designated as the destination for  fax calls.

CPM

CPM (Central Processor Module) The  CPM module is equipped  standard  in  KSU1.   This board contains  all circuitry required to control the  fully  equipped  DX-80.   The  system  uses  the CPM to  perform all digital  voice switching and call processing  data switching. The  CPM has one ribbon  cable connector for connection  to the KSU1  408M and five  (5) connector sockets for connection of the system built-in modem,  voice processor,  and second  cabinet (KSU2).  Since  the CPM comes installed inside of KSU1 the CPM ribbon cable is already  in place and connected  to the KSU1-408M J5 socket.   Assuming the orientation of the  KSU1 cabinet is  installed on the wall; the  two horizontal connector  sockets in the upper  right corner  of the CPM are for  the MDM (Modem  Module).   The  connector socket labeled “2nd  Cabinet”  is for connection  to the KSU2-408E if that  expansion is  required.   The  remaining two connector sockets on the  CPM, one at the  left side, the other at  the right  side are for  the  voice processor  solution.   Note:   The  voice processor solution can be any of  three possible choices:  AAM,  7271C,  or 7270C.

Memory Module installation or replacement

Memory Module installation or replacement
Note: The Memory Module has a proprietary formatting scheme — do not attempt to install a non-ESI drive.
Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the Memory Module will require that the ESI-100 be taken out of service.
All of the ESI-100’s configuration data and customer recordings are stored in the Memory Module.
Replacing it, therefore, requires re-programming and re-recording, unless you have previously performed a backup
using ESI System Programmer software. (Prompts stay intact, however.)
Note: Be sure to observe all proper procedures regarding the prevention of electrostatic discharge (ESD) when
performing the following procedures; otherwise, circuit boards may suffer damage.
Install the CompactFlash Memory Module
1. Open the lid of the cabinet (you must remove
the screw on the top that secures the lid).
2. Power down the system.
3. Plug the Memory Module into the J14 connector
on the main board (see diagram, right).
4. Secure the lid to the KSU

service code

: Service Code Setup (for System Administrator)  to customize the Service Codes for the System Administrator. You can customize additional Service Codes in Programs 11-11 ~ 11-16. The following chart shows: • The number of each code (01 ~ 50). • The function of the Service Code. • The type of telephones that can use the Service Code. • The default entry. For example, dialing item 26 allows users to force a trunk line to disconnect.

system numbering plan

System Numbering  to set the system numbering plan. The numbering plan assigns the first and second digits dialed and affects the digits an extension user must dial to access other extensions and features, such as service codes and trunk codes. If the default numbering plan does not meet the site requirements, use this program to tailor the system numbering to the site. Caution! Improperly programming this option can adversely affect system operation. Make sure you thoroughly understand the default numbering plan before proceeding. If you must change the standard numbering, use the chart for Table 2-1 System Numbering Default Settings on page  2-57  to keep careful and accurate records of your changes. Before changing your numbering plan, use PC Pro to make a backup copy of your system data. Changing the numbering plan consists of three steps: Step 1 : Enter the digit (s) you want to change You can make either single or two digit entries. In the Dialed Number column in the  Table 2-1 System Numbering Default Settings on page  2-57, the nX rows (e.g., 1X) are for single digit codes. The remaining rows (e.g., 11, 12, etc.) are for two digit codes. • Entering a single digit affects all the Dialed Number entries beginning with that digit. For example, entering 6 affects all number plan entries beginning with 6. The entries you make in step 2 and step 3 below affect the entire range of numbers beginning with 6. (For example, if you enter 3 in step 2 the entries affected are 600 ~ 699. If you enter 4 in step 2 below, the entries affected are 6000 ~ 6999.) • Entering two digits lets you define codes based on the first two digits a user dials. For example, entering 60 allows you to define the function of all codes beginning with 60. In the default program, only *  and # use 2-digit codes. All the other codes are single digit. If you enter a two digit code between 0 and 9, be sure to make separate entries for all the other two digit codes within the range as well. This is because in the default program all the two digit codes between 0 and 9 are undefined.
