1. CHAPTER 1
GETTING STARTED
1.1 ABOUT CEC/IMC MANAGER V5.0
Starting with release (version) 5.0 the CEC/IMC Manager is a 32 bit
Windows NT application. To provide remote management capability
the architecture of the CEC/IMC Manager is Client/Server. The
application is divided into two executables; GUI_SRVR.exe is the
Server application that runs as a Windows NT service, and W_GUI.exe
is the Graphical User Interface (GUI) application run from the ICON
selected in the WINMOM program group. This release of CEC/IMC
Manager also includes an optional SNMP agent that runs as a Windows
NT service. The SNMP agent is required to provide a Network
Management station remote monitoring of the CEC/IMC Manager
directly and the CEC/IMC by proxy. The installation procedure for this
agent is found in APPENDIX C - SNMP AGENT and PROXY for
CEC/IMC (Optional). Once installed, configure the agent in
accordance with the configuration procedures in EDACSManagement Installation and Technical Reference Manual (LBI-
39171).
®
Network
Throughout this pro gram there will be references to configuration d ata
saved to, stored at, and read/retrieved from the CEC/IMC Manager hard
disk. This hard disk is located at the machine (PC) that the
GUI_SRVR.exe is running from, not the machine running the GUI
application unless the same machine is performing both services. In
most cases, if not all, the machine running the server (GUI _SRVR.exe)
will be local to the CEC/IMC.
The CEC/IMC Manager for Windows NT Client has been ported to
HP-UX platforms to run in conjunction with Network Manager. For
users running an HP-UX version of the CEC/I MC Manager Client all
references in this manual to W_GUI.exe, Graphical User Interface
(GUI), or CEC/IMC Manager for Windows NT Client should be
considered "CEC/IMC Manager HP-UX Client."
1.2 ABOUT THIS MANUAL
This manual describes the CEC/IMC Manager (MOM PC) user
interface and functions. It is intended to aid the user in performing
various CEC/IMC Manager functions such as CEC/IMC configuration

1.3 DATA LOGGING FEATURE
One of the most important features of the CEC/IMC Manager
(MOM PC) is its ability to log data. All data that is placed on the GSC
Bus in the CEC/IMC is logged at the MOM Controller Board. The
MOM Controller Board then periodically dumps its data log buffer to
the CEC/IMC Manager through their serial link. The CEC/IMC
Manager writes this data to its hard disk, where it can be extracted and
viewed either on- or off-line. The on-line functions are available under
System Monitoring Diagnostics. The off-line functions are:
CALLS.EXEUsed to extract all calls made within the
CEC/IMC.
GSCMON.EXEUsed to extract all messages from the logged
data.

2.6 UPGRADE CEC/IMC MANAGER
NOTE
Ensure that the requirements of MULTIPLE REMOTE
CLIENTS (Step 2.5 above) are fulfilled before proceeding.
2-3
LBI-39224
1.VERIFY that the MIGRATE.BAT utility has been executed to
save the original (DOS) CEC/IMC Manager configuration.
2.Insert the "Install" CEC/IMC Manager V5.0 for Windows NT
diskette and execute SETUP.EXE. This setup utility will:
– Copy all necessary Executables and DLLs
– Install the CEC/IMC Manager server as a service
– Install the CEC/IMC Manager GUI
– Setup Program Groups and CEC/IMC Manager Icons
– Execute the necessary registry edits
3.(OPTIONAL) Insert the "Install" SNMP Agent Diskette and
execute SETUP.EXE.
4. Insert the "Migrate Utility" diskette and execute
MIGRATE.BAT to transfer the previous (DOS) CEC/IMC
Manager configuration to the just installed (Windows NT)
CEC/IMC Manager. This should be the second time
MIGRATE.BAT was run since the original (DOS) CEC/IMC
Manager configuration was saved using this utility on the
(DOS) CEC/IMC Manager machine. In a DOS Window:
From the C:\WINMOM prompt type a:\migrate TO.
5.Reboot the CEC/IMC Manager PC.
6.Double-click on the CEC/IMC Manager icon (in the
WINMOM program group) to execute the CEC/IMC Manager
GUI.
IMPORTANT NOTE
Expect to see "NOVRAM MISMATCH" Popup windows.
These occur because the DOS MOMPC did not save Bus/Slots
to disk. Although the Migration utility pre served much of the
configuration, the bus/slots at the CEC/IMC Manager will be
zero and the MOM Controller will hold the valid Bus/Slots
configuration. By following steps 7-13 the entire slot databa se
should be stored to the CEC/IMC Manager V5.0 hard disk.

OPERATION AND CONFIGURATION
The primary intent of this chapter is to describe CEC/IMC Manager
program operation, and valid CEC/IMC Manager and CEC/IMC Digital
Audio Switch configuration settings. In some cases detailed systemlevel information is presented where necessary. This chapter is
arranged in the order recommended for the set-up of a new CEC/IMC
Digital Audio Switch. Refer to the set-up information within
LBI-38938 and other referenced documents for additional information
as necessary.
3.1 STARTING THE PROGRAM
This chapter assumes that program software loading and system
hookups have been completed. The program software is installed at the
factory for new systems; however, refer to Section 2.7, SYSTEM
HOOK-UP of the previous chapter if system hookup has not been
accomplished.
3.1.1 Default User Account

3.2 USER ACCOUNT CONFIGURATION
Up to twelve (12) different user accounts can be configured for the
CEC/IMC Manager. Each user has an account which defines the user's
name, password, and access level. The default user account,
"MOMUSER," has a password of "GUEST" and a "System
Administrator" access level. For Network Manager stations the default
user account is "NMUSER" and has a password of "GUEST." This
default account is active the first time the program is executed and it
remains as one of the twelve accounts unless it is deleted. These log-in
defaults are provided in the PASSWORD.DAT file that is part of the
CEC/IMC Manager installation. To prevent unauthorized access,
deleting this default account after at least one "System Administrator"
account is configured and safeguarding the PASSWORD.DAT file by
the system administrator are recommended. This file may be used as a
backup in the event that passwords are forgotten or the installed
PASSWORD.DAT file is deleted. All user accounts are set up from the
CEC/IMC Manager Configuration menu.
IMPORTANT NOTE!
In multi-user environments it is possible for two users to be
changing the same data. In these situations, the data saved,
and subsequently used to configure the CEC/IMC, will be
from the last "Save." Therefore, it is important to give
administrative privileges (access level) only to those users
authorized to make changes to the system configuration. See
also NOTE below.

3.3 CEC/IMC MANAGER FONT SELECTION
The CEC/IMC Manager Graphical User Interface (GUI) can be
executed on the Network Management platform, which maintains a set
of fonts different fro m the CEC/I MC M ana ger P C fo nts. T he re for e, the
CEC/IMC Manager has a font selection dialog box; this font selection is
saved to disk by User Name. In some instances a particular font
selection that works fine at one platform may not work properly at
3-8
LBI-39224
another platform when the user logs in; in such instances a user may
need to have accounts at each platform under different user names with
a font selection for that particular platform. Because there is variation
between platforms font selection may be somewhat of a "trial-anderror" process to determine the best font combinations. See
APPENDIX D - FONT SELECTABLE DIALOG BOXES for a list of
dialog boxes that are affected by the user selected fonts.
CEC/IMC Manager font selection is done in the Font dialog box. From
the CEC/IMC Manager main menu bar select Configure System /

The selected serial port interrupt request line (IRQ) and base I/O port
address settings are established from the Microsoft Windows NT
Control Panel program settings. Typically, no I RQ or address c hanges
are ever required. However, if using non-standard serial port hardware,
changes may be necessary. If using non-standa rd serial port hard ware,
consult the hardware manufacture's documentation for specific IRQ and
base I/O address details.
CEC/IMC Manager-MOM Baud Rate
Baud rate selection for the CEC/IMC Manager ⇔ MOM Controller
Board serial link is accomplished using the CEC/IMC Manager BAUD
Rate drop-down list box. In this list box baud rates of 9600 and 19.2k
baud are available, select 9600 or 19.2k baud as required. This setting
configures the previously chosen PC COM port for the selected rate.
Since the MOM Controller Board port used for CEC/IMC Manager
interfacing is auto-baud sensing, a baud rate change at the MOM
Controller Board is not necessary when a change is made in this list
box.
System Manager-MOM Baud Rate
The MOM Controller Board port used for interfacing with the System
Manager computer is configurable for 9600 or 19.2k baud using the
System Manager BAUD Rate drop-down list box. Unlike the
CEC/IMC Manager ⇔ MOM Controller Board setting, this setting
must match the setting at the System Manager before MOM Controller
Board ⇔ System Manager communication can occur, the System
Manager is not equipped with an auto-baud serial port. Refer to your
particular System Manager LBI for System Manager baud rate
configuration information. Select 9600 or 19.2k baud as required from
the drop-down list box.
Data Logging Of GSC Traffic
Once each day at midnight (00:00), the CEC/IMC Manager creates a
new datalog file and it names the file in accordance with the date. For
example, a datalog file created on July 2, 1996 will be named
07_02_96.DLG
Calls Translation and GSC Monitor functions (available by selecting
Monitor System on the CEC/IMC Manager menu bar) described in
Chapter 4, SYSTEM MONITORING, or the CALLS.EXE and
. This data can be viewed using the on-line
3-11
LBI-39224
GSCMOM.EXE off-line programs as described in Chapter 5, OFFLINE DIAGNOSTIC FUNCTIONS.
If data logging is desired, select the Enable Datalog check box. With
this feature enabled the CEC/IMC Manager will log GSC traffic such as
channel assignments and drops.
The datalog delete threshold feature automatically deletes old datalog
files which are stored on the CEC/IMC Manager's hard disk drive. A
stored datalog file that is older than the number of days in the Datalog
Delete Threshold will be deleted at midnight. This prevents hard disk
drive "disk full" errors. Datalog files will also be deleted if the Datalo g
Delete Threshold number is reduced. For example, if the previous
number was "8" (8 days) and the number is reduced to "5" (5 days) in
the CEC/IMC Manager Configuration dialog box, the three datalog
files that are more than 5 days old will be deleted from the hard disk
drive at midnight. The range for the Datalog Delete T hreshold number
is 1 to 50. The value selected here should be at least equal to the
number of days between back-ups of the datalog files such that they are
saved before the CEC/IMC Manager automatically deletes them from
the hard disk drive. ERROR.DLG and WARN.DLG files are not
affected by the Datalog Delete Threshold setting.

3.6 SYSTEM MANAGER DATABASE UPLOADS
The CEC/IMC uses data from the System Manager Unit and Group
databases to control routing of all wide area (multisite) calls. These
databases must be setup correctly at the System Manager before the
System Manager data is transferred to the CEC/IMC. The CEC/IMC
3-14
LBI-39224
Manager user is able to select unit, group, and site d a ta from the System
Manager; or unit, group, and site data, along with conventional and
console unit ID databases fro m the CEC/IMC Manager hard disk, a nd
broadcast (transfer) this data to all interface modules. If the data is
transferred from the System Manager it is also stored on the CEC/IMC
Manager hard disk.
NOTE
If the System Manager operates with version 4.0 (or earlier)
software, console aliases and LIDs can be changed at the
CEC/IMC Manager. However, it is recommended that a
console LID stored at the CEC/IMC Manager be given the
same alias as the corresponding console LID at the System
Manager; in other words, changing console aliases at the
CEC/IMC Manager is not r ecommended if a System Mana ger
exists.
If the network's System Manager operates with version 5.0 (or
later) software, a console alias cannot be changed at the
CEC/IMC Manager. Therefore, CEC/IMC Manager console
aliases will always match System Manager console aliases.
NOTE
Conventional Channel aliases and LIDs are assigned to a
channel number at the CEC/IMC Manager, but it is
recommended that these entries match valid conventional
channel aliases and LIDs defined at the System Manager. This
will ease conventional channel identification during patch
operations. A console communicates with a conventional
channel by its channel number—not its LID number.
Database transfers (uploads/downloads) are accomplished using the
System Mgr/Network Mgr Entity Database dialog box. From the

from a previous System Manager upload. In addition, conventional and
console unit ID databases can be uploaded from the CEC/IMC
Manager. The conventional database is built using the
Conv. Interface Adapter Configuration menu op tion from the VMIM
menu (CEC/IMC Configuration). The console da tabase is built using
the Console User Profile menu option from the
Console Configuration menu. A transfer will be aborted if a full
transfer from the System Manager begins while the CEC/IMC M anager
based transfer is in progress, or if a database file read error occurs. If a
CEC/IMC Manager based transfer is in progress and a partial System
Manager transfer occurs, the CEC/IMC Manager based transfer request
will be "failed," CEC/IMC Manager requests are not queued. T his is to
allow other GUI clients an opportunity to submit requests.

3.7 TDM BUS CONFIGURATION
The CEC/IMC Digital Audio Switch is equipped with a Time Division
Multiplexed (TDM) network which transfers audio signals, modem data
signals, and user data signa ls througho ut the switch. TD M network b us
and time slot configurations are performed from the CEC/IMC
Manager. These configuratio ns set the CEC/IM C for 4- o r 8-T DM b us
operation and allocate a TDM time slot for each input channel. TDM
time slot allocation procedures are described in the next section.
TDM bus configuration must match the specific hardware installed
within the CEC/IMC, early CEC/IMC Audio Boards utilized only four
(4) buses and all later Audio Boards utilize eight (8) buses. A
CEC/IMC with 4-bus Audio Boards will not route signals correctly if
the CEC/IMC is configured for eight buses. A CEC/I MC with 8-bus
Audio Boards but configured for 4-bus operation will operate correctly;
however, approximately one-half of the total TDM time slots will not
be available. The 8-bus Audio Boards include 19D903302P1 Rev. F
(and later) boards with 344A3561G3 (and later) firmware, and all
19D903302P3 boards. All T1/E1 Interface Cards are 8-bus capable.
NOTE
The MOM Controller Board default TDM bus setting is eight.
This default number is established within the MOM firmware.
If the MOM Controller's non-volatile RAM (NOVRAM) is
cleared, the CEC/IMC will return to 8-bus operation without
intervention from the CEC/IMC Manager. If 4-bus operation
is required, the TDM bus configuration mus t be reset to the
required number– 4 –after a MOM Controller Board
NOVRAM clear. Refer to the diagnostic procedures within
LBI-38938 for instructions on clearing Controller Board
NOVRAM.

Figure 11 TDM Bus Configuration Dialog Box
Current TDM Bus Configuration
When the TDM Bus Configuration dialog box is first opened this field
may be blank until the CEC/IMC Manager receives the current TDM
Bus configuration from the CEC/IMC MOM Controller. T he current
TDM Bus configuration is then displayed in this read-only field. TDM
bus configuration must match the specific hardware installed
within the CEC/IMC for proper and effective routing of audio
signals.
New TDM Bus Configuration
The number of TDM Buses the CEC/IMC will use to route audio
signals is configured from this field. Select the required number of
TDM Buses from the drop-down list box. TDM bus configuration
must match the specific hardware installed within the CEC/IMC
for proper and effective routing of audio signals.
Number of Slots Remaining
This read-only field displays the current number of TDM time slots
available for assignment (allocation). This number will decrease as
"site" channels are configured and allocated TDM time slots,
conversely this number will increase as channels are "unconfigured."
Changing the number of TDM Buses (above) will have a significant
effect on the number of slots available; increasing the number of buses
3-20

This section describes channel-related configurations applicable to
"site"-type (MIM, NIM, VMIM, PIM and CTIM) interface modules
that are performed at the CEC/IMC Manager. NIM, VMIM, PIM and
CTIM site-type interface modules do not actually interface with
EDACS trunked sites; however, each interface module is assigned a
unique site assignment number (1 thru 32). Each interface module type
will be discussed separately because, although similar, they do have
slight differences and this is an important step in CEC/IMC switch
setup. Also, some modules may be equipped with the new T1/E1
Interface Card (currently only MIMs, NIMs, and PIMs may be so
equipped). Configuration of both Audio Board-equipped interface
modules and T1/E1 Interface Card-equipped interface modules will be
covered in those cases.
3-21
LBI-39224
NOTE
In most cases, the term "site" in this program does not refer to
an EDACS trunked site or any other type of radio system. I t
refers instead to a site-type interface module within the
CEC/IMC or StarGate Controller Digital Audio Switch. The
number that follows is the interface module's site assignment
number. This number corresponds to and matches the site
assignment number set by the 5-bit DIP switch setting on the
interface module's Controller Board.
Prior to actual channel configuration the interface module to be
configured must be selected. From the CEC/IMC Manager menu bar
select Configure System / CEC/IMC Configuration / the desired
interface module (MIM, NIM, VMIM, PIM or CTIM) from the
CEC/IMC Configuration menu, shown in Figure 12. When an
interface module is selected from the CEC/IMC Configuration menu
the Site Channel Configuration List dialog box for that module is
displayed.

T1 is a digital transmission facility operating at 1.544 Mbps (million
bits per second) in a full-duplex, time-division-multiplexing mode. T1
is the first level or primary rate within a digital transmission and
switching hierarchy defined by AT&T called a T Carrier System. North
America has adopted the T Carrier System as a standard for digital
transmission of voice, data, and images. Time-division multiplexing
permits the derivation of logical channels within the serial bit stream.
The CEC/IMC T1/E1 Interface will allocate twenty-four 64 kbps T1
channels.
E1 digital transmission is very similar to T1. The major difference is in
the bit rate. E1 is a digital transmission facility operating at 2.048
Mbps. The difference in bit rate allows for different channel allocation
schemes. The CEC/IMC T1/E1 Interface will allocate thirty-one 64
kbps E1 channels. E1 transmission has been adopted as the digital
transmission standard in European countries.
T1/E1 selection is performed at the CEC/IMC Manager on a CEC/IMC
wide basis. Changing the line type will cause the entire T1/E1 databa se
to be reset (lost) for all T1/E1 "sites." T1 or E1 selection is d ependent
upon the line service coming into the CEC/IMC (T1 and E1 lines are
physically different), and as mentioned above, depends upon what part
of the world you are in. Selecting T1 or E1 should only be required
when the system is first configured, after that the current system
configuration will be indicated when the Audio Interface Type dialog
box appears on your screen and changing line type is not necessary or
desired. Choose the OK button and the

CEC/IMC to Disk
Choose the
CEC/IMC to Disk
button to write the current CEC/IMC
configuration data to the CEC/IMC Manager hard disk. This action
will overwrite the current CEC/IMC Manager configuration for the
selected interface module. This function is useful if the CEC/IMC
Manager configuration database is lost for any reason. A difference
between CEC/IMC and CEC/IMC Manager databases will be evident
3-29
LBI-39224
by comparing the CEC/IMC Manager and CEC/IM C list boxes in the
Site Channel Configuration dialog box. Ensure that the CEC/IMC
configuration is correct, then choose the CEC/IMC to Disk button to
restore the CEC/IMC Manager configuration database (for the selected
interface module).
Channel Selection
Select a channel (1 thru 32) for configuration from the CEC/IMC
Manager list box, only one channel may be selected at a time. The
selected channel and its configuration data will be displayed in the ed it
fields above the CEC/IMC Manager list box.
Input Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) applied to the selected channel's line input. Enter
(type) the required value in the text box. The setting should b e equal to
the voice peak (test tone) level applied to the channel's line input.
Voice peak levels are +10 dBm greater than average voice levels.
Valid range is -25.0 dBm to 12.0 dBm, adjustable in 0.5 dBm
increments. The program automatically rounds-off non-0.5 dBm
fractional entries to the nearest 0.5 dBm point. Input Signal Level
default = 0 dBm.
NOTE
If Automatic Level Control (ALC) is disabled for the selected
channel, subtract 1.5 dBm from the required Input Signal
Level setting. For example, if the required input signal level is
-10 dBm, enter -11.5 dBm. ALC is disabled by setting the
ALC text box to "NO."
LBI-38938 contains a line level adjustment overview section which
contains general information and general recommendations for both
input and output level settings.
Output Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) sent out by the selected channel's line output. The
setting specifies the voice peak (test tone) level sent out by the channel.
The valid range is -25.0 dBm to 13.0 dBm, generally in 0.5 dBm
increments, select the required value from the drop-down list box.
Output Signal Level default = 0 dBm.
3-30
LBI-39224
Channel Signaling
This drop-down list box specifies the type of channel signaling sent out
by the selected channel for control of external equipment such as an
EDACS trunked site or co-loc ated mux equipment. Valid settings are
"NONE" for no signaling, "TONE" for tone control signaling, "E&M"
for M-lead control signaling, and "BOTH" for both tone and M-lead
control signaling. Channel Signaling default = "NONE."
EDACS trunked sites require specialized tone control signaling for
transmit keying. For a MIM, all utilized channels require either a
"TONE" or a "BOTH" setting. Specific tone level settings are
accomplished via the "Secure Tone" text box described in the following
section.
Secure Tone
This setting establishes the level of the 2175 Hz secure tone and
transmit hold tone sent out by the Audio Board's channel pr ior to and
during a switch-to-site transmission. The set level is only utilized if
Channel Signaling is "TONE" or " BOTH." Valid range is -10 dBm to
11 dBm, which specifies the secure tone level. The 2175 Hz transmit
hold tone is always sent out 30 dBm below the secure tone setting.
NOTE
The secure tone and transmit hold tone are set on a per Audio
Board basis. For example, setting channel 2 equal to 5 dBm
will simultaneously set channels 1, 3 and 4 equal to 5 dBm.
Unlike conventional base statio ns, E DACS trunke d site b ase stations d o
not require a function tone for proper transmit keying. Therefore, the
presence of a functio n tone is not guaranteed and no longer specified
for MIMs.
Bus/Slot Equipped
All utilized channels within an interface module must be allocated a
time slot on the CEC/IMC TDM network. Allocate a time slot to the
selected channel by setting Bus/Slot Equipped to "YES." A channel
will not route audio correctly if is not allocated a time slot. Set all
unused channels to "NO," the default setting.
3-31
LBI-39224
For example, if the currently selected site-type interface module is a
20-channel MIM with five (5) Audio Boards addressed 1 thru 5,
Bus/Slots Equipped for channels 1 thru 20 must be "YES."
NOTE
In earlier CEC/IMC firmware/software releases, slot
allocations could only be made contiguously starting with
channel one (1). In some systems this produced slot allocation
inefficiencies, i.e., some slots had to be allocated but were
never used. CEC/IMC software/firmware release 5.0 (and
later) provides non-contiguous slot allocations. In this release,
only those slots actually required need be allocated. For
example, channels 1 and 4 can be allocated slots without
allocating slots to channels 2 and 3.
Notch Filter
CAUTION
DO NOT enable the 2175 Hz Notch Filter for any channel if
the respective Audio Board part number is 19D903302P1 (any
revision).
Each Audio Board channel is equipped with a 2175 Hz notch filter
circuit which when enabled eliminates destructive interference of the
channel's 2175 Hz transmit keying tone. In some cases, this destructive
interference or "talk down" can cause incorrect (early) trunked site
channel drops. To enable the selected channel's notch filter, enter
"YES" in the Notch Filter text box. Notch Filter default = "NO"
(disabled).
ALC
CAUTION
DO NOT enable ALC for any channel if the respective Audio
Board part number is 19D903302P1 (any revision).
Automatic Level Control (ALC) provides compensation for signal level
variances in a channel line input signal. As required, enable ALC for
3-32
LBI-39224
the selected channel by entering "YES" in the ALC text box or disable
it by entering "NO."
Save and Send MIM Audio Board Configurations
When channel configuration of the selected interface module is
complete, the Site Channel Configuration dialog box changes must be
sent to the CEC/IMC before the changes will take effect. This
reprograms the MIM Controller Boards. However, it is important to
save the new configuration prior to sending it to the CEC/IMC because
a send will send the last configuration that was saved to disk; saving
first ensures that the actual CEC/IMC channel configuration will be the
same as the channel configuration stored on the CEC/IMC Manager
hard disk. To save and send configurations, a ction is required first in
the Site Channel Configuration dialog box and then in the
Site Channel Configuration List dialog box.
Site Channel Configuration dialog box
Save
Choose the Save button to perform an immediate save of the currently
selected site-type interface module's channel configuration. Other
"sites" displayed in the list box located at the top of the dialog box are
not saved. This channel configuration is saved on the CEC/IMC
Manager's hard d isk drive. Any pre vious channel configuratio n for the
"site," if present, is erased and replaced with the current channel
configuration. If the CEC/IMC Manager is running remotely or as a
part of the EDACS Network Manager, this configuration is saved on the
CEC/IMC Manager server, typically local to the CEC/IMC; it is not
saved at the remote location.
Save As...
Choose the Save As… button to allow the currently selected site-type
interface module channel configurations to be saved as a different sitetype interface module. It is provided to speed configurations when
similar MIM configurations are required. Upon choosing Save As… a
small dialog box, Figure 17, will appear which allows entry of a new
MIM number. Select the desired MIM number from one of the choices
in the drop-down list box, the choices listed are the selected MIMs in
the Configured/Active Sites list box. Like Save, Save As… stores
channel configuration on the CEC/IMC Manager server.
3-33
LBI-39224
Figure 17 "Save As…" Dialog Box
For example, if "Site 8" is the currently selected site-type interface
module and "Site 12" requires similar configuration settings, this b utton
may be used to save the "Site 8" configuration as "Site 12" (save to
"12"). The new "site" may then be changed later, as required, by
selecting it from the selection list box, changing the configuration as
required, and then choosing Save.
Close
Choose the Close button to exit the Site Channel Configuration
dialog box and enter the Site Channel Configuration List dialog box.
If any changes have been made and not saved, you will be prompted
(Write Changes to Disk?) to save and exit (Yes), exit without saving
(No), or cancel the Close command and remain in the dialog box
(Cancel).
Site Channel Configuration List dialog box
Send
Choose the Send button to send the site channel configuration data to
the respective interface module. This procedure must be performed
before the interface module will operate with the new configuration.
Only configured and configured-and-active (C and C/A prefixes)
configurations may be sent. All configuration data is sent to the MOM
Controller Board; the Audio configuration is sent directly out from
there to the respective interface module Controller Board. A "Send to
Site Successful" message will be received to confirm that the data was
received by the interface module Controller Board. Bus Slot
configuration data is compared to the current configuration at the
CEC/IMC Manager; if different, it is sent to the MOM Controller
Board (if not, no further action is taken by the system) and when the
3-34
LBI-39224
MOM Controller Board receives this new data it will send an
acknowledgment message back to the CEC/IM C Manager, which will
then display the confirmation box: "Do you want to activate TDM Bus
Slots? OK - will cause all CTRL boards to reset." Choose OK to
activate TDM Bus Slots (resetting Controller Boards) with the new Bus
Slot configuration da ta, choo se Cancel to no t activate TDM Bus Slots
with the new Bus Slot configuration data (keeping the previous
configuration) and return to the Site Channel Configuration List
dialog box.
Close
Choose the Close button to exit the Site Channel Configuration List
dialog box and return to the CEC/IMC Manager main window. Any
"**" (unconfigured and unsaved) sites appearing in the
Configured/Active Sites list box will be removed and returned to the
Configurable Sites list box.
T1/E1 Interface Card-Equipped MIM Configuration
This section describes configuration for channels of T1/E1 Interface
Card-equipped interface modules (currently only MIMs, NIMs, and
PIMs are so equipped). Channel configurations are performed from the
T1/E1 Digital Site Configuration dialog box (Figure 18) and from the
T1/E1 Interface Card Auto-configuration dialog box (Figure 19). As
was the case with Audio Board-equipped site-type interface modules,
only those "sites" which were selected in the
Site Channel Configuration List dialog box are available for channel
configuration.
NOTE
Like the CEC/IMC Audio Board, each T1/E1 Interface Card
within a CEC/IMC interface module must have a unique board
address setting. This address is 1 - 8 (addresses 2 - 8 are
currently not available).
3-35
LBI-39224
NOTE
T1/E1 selection is performed at the CEC/IMC Manager on a
CEC/IMC wide basis. Changing the Line Type will cause the
complete T1/E1 database to be reset (lost). The Line Type
shown as the "default" when the Audio Interface Type dialog
box appears is how the system is configured and Line Type
should not be changed.
The T1/E1 Interface Card provides a built-in T1 or E1 port for
CEC/IMC interface modules. This port allows direct interfacing to
T1/E1 microwave, fiber-optic, or leased lines facilities. Consequently,
co-located T1/E1 multiplexing (mux) equipment at the CEC/IMC is
eliminated when the T1/E1 Interface Card is employed. CEC/IMC
Audio Boards are also eliminated within the particular interface
module. Within each of these interface modules, one or more T1/E1
Interface Cards replace all Audio Boards. The T1/E1 Interface Card
furnishes twenty-four full-duplex T1 channels in T1 mode and thirtyone full-duplex E1 channels in E1 mode. In addition to its T 1/E1 po rt,
the T1/E1 Interface Card also contains eight subrate ports which,
depending upon board configuration, can provide modem-less data
links over spare T1/E1 channels to either internal or external devices.
Some, all, or none of these ports can be utilized depending on board
configuration. Five of the subrate ports support synchronous or
asynchronous data links and the remaining three are synchronous-only
ports.
T1/E1 Digital Site Configuration
Networked Systems Considerations
Any system nodes that are connected using T1/E1 Interfaces must
remain frequency locked at all times. The T1/E1 Interface design
allows for total network synchronization by offering the following
CEC/IMC Configuration options. Each of these options are selectable
by configuration of both the Clock Boards and the T1/E1 Interface
Cards.
3-36
LBI-39224
1. Master - Redundant Clock Circuits generated by the Clock
Board in a FREE RUN mode. This allows any CEC/IMC to
become the master source of Network timing. All nodes
connected to this CEC/IMC will be in the slave mode. This
mode is established by setting the Clock Board DIP switches
to "Master" mode and all the T1/E1 Interface Cards' Slave
Clock option to "NONE."
2. T1/E1 Slave - Redundant Clock Circuits generated by the
Clock Board synchronized to 1 (or 2 with redundancy) T1/E1
Interface into the CEC/IMC. The CEC/IMC can be slaved to
an external node that is c onnected through a T 1/E1 link, and
no additional timing source is needed. Timing from the T1/E1
line is passed to the Clock Board from the T1/E1 Interface
Cards through a redundant set of synchronization clocks
named Slave A and Slave B. Each T1/E1 Interface Card can
provide Slave A, B or A&B. This mode is established by
setting the Clock Board DIP switches to "Slave to 8kHz" and 1
T1/E1 Interface Card Slave Clock option set to "SLAVE A,"
with another set to "SLAVE B" for redundancy, or 1 T1/E1
Interface Card set to "SLAVE A&B" for no redundancy.
3. Slave to external 1.544 MHz - Redundant Clock Circuits
generated by the Clock Board synchronized to 1 (or 2 with
redundancy) external clock source. Any CEC/IMC can be
synchronized to the timing output from a T1/E1 multiplexer,
microwave radio, fiber network, etc. Connect the external
timing source to both Clock Boards in the CEC/IMC for
redundancy. This mode is established by setting the Clock
Board DIP switches to "Slave to Ext. 1544 kHz" and all T1/E1
Interface Cards' Slave Clock option to "NONE."
4. Slave to external 2.048 MHz (E1 mode only) - Redundant
Clock Circuits generated by the Clock Board synchronize d to
1 (or 2 with redundancy) external clock source. Any
CEC/IMC can be synchronized to the timing output from a
T1/E1 multiplexer, microwave radio, fiber network, etc.
Connect the external timing source to both Clock Boards in the
CEC/IMC for redundancy. This mode is established by setting
the Clock Board DIP switches to "Slave to 2048 kHz" and all
T1/E1 Interface Cards' Slave Clock option to "NONE."
The following configuration guidelines must be followed for network
synchronization:
3-37
LBI-39224
1. One node in the system must be the MASTER source of
network timing. The CEC/IMC will support a primary and
redundant (or alternate) MASTER sources of timing as
indicated above.
2. A MASTER node can be defined as a site, a Jessica, a T1/E1
link, or a CEC/IMC.
3. All leased T1/E1 facilities from the telephone company are
frequency locked by the phone company. If there are any
phone company T1/E1 connections, one of the connections
must be the MASTER source of timing. Any other phone
company connections may be the redundant MASTER source
of timing. Phone company T1/E1 connections include leased
lines for sites/multinode and T1/E1 connections through an
MD110 (Jessica).
4. Any nodes using analog interfaces (including analog
connections from an MD110 to the phone company) may be
disregarded for synchronization purposes.
5. If a node is not a MASTER timing node, it must be slaved to
the T1/E1 link going towards the MASTER node.

Analog or Digital Voice
In addition to T1 or E1 selection, T1/E1 Interface Card configuration
includes selecting one of three primary board operating modes:
– Analog/modem mode ("Analog or Digital Voice using
Modems")
In the analog/modem mode, the T1/E1 Interface Card transfers
PCM-encoded signals between the CEC/IMC TDM network
and the T1/E1 line. PCM-encoded signals transferred b y this
mode include analog (clear) voice, modem-encoded digital
voice, and/or modem-encoded data signals. In this mode each
site channel is assigned to a T1/E1 channel. In addition, this
mode allows use of the T1/E1 Interface Card subrate ports if
T1/E1 channels are available after site channel assignments.
Two CEC/IMC TDM bus slots coincide to one full duplex
T1/E1 Channel. This is exactly analogous to a CEC/IMC
Audio Board channel where two TDM bus slots coincide to
3-39
LBI-39224
one full duplex 4-wire 600-ohm audio channel provided by the
Audio Board. The T1/E1 Interface Card extracts a signal from
one bus slot and sends it out on a T1/E1 channel.
Accordingly, signals received on this same T1/E1 channel are
applied to a different CEC/IMC TDM bus slot.
– Digital voice/data using subrate ports mode (currently not
supported)
– Digital voice/data using T1/E1 mode (currently not
supported)
Line Type
This is a read-only field which indicates which type of line (T1 or E1)
that the system is configured for.
Frame Format
Framing deals with how the digitized data stream is configured
(formatted), a data stream with one framing format would not be
recognized by a system with another frame format. The possible T1
formats are 4-Frame Multiframe (F4), 12-Frame Multiframe (F12,
D3/4), Extended Superframe (ESF), and Remote Switch Mode (F72).
The possible E1 formats are Doubleframe and CRC Multiframe. The
format is determined by the service line used. Select from the available
choices in the drop-down list box to match the line format.
Line Code
The line code indicates the method used to encode long strings of
zeroes. The receiving end of a T1/E1 link would not be able to remain
in sync if long strings of zeroes were transmitted. The possible T1 line
codes are B8ZS and AMI w/ZCS. The E1 line code is HDB3. The line
code also is determined by the service line utilized. Select from the
available choices in the drop-down list box to match the line.
Signaling Type
This signaling is used by the T1/E1 Interface Card to transmit channel
status information (busy or idle). T1 uses bits robbed from the channel
data to convey this information. E1 uses a dedicated channel to send
signaling information for all channels; therefore, only 30 user channels
are allowed. In a CEC/IMC system, signaling must be set for MIM site
interfaces, and the T1/E1 muxes and base stations at the associated site
location must be configured for E&M Signaling unless the site is all
digital (no analog voice). Signaling should not be set for any other
device types. The types of signaling are No Signaling (both T1 and
3-40
LBI-39224
E1), Robbed Bit for T1, and CAS-CC for E1. Select the signaling type
from the drop-down list box.
Line Length
This is the distance between the CEC/IMC and the device at the other
end of the T1 line, which could be a microwave transceiver, a mux in
co-located site equipment, CSU, etc. Line effects change the signal
slightly, and the changes become more pronounced the further the
signal travels down the line. The outgoing original signal is modified
based upon line length so that the signal arriving at the destination
closely resembles an ideal signal. Select the line length from the dropdown list box for T1 applications. E1 applications do not support
selectable line lengths.
Set Site Channel Disbursement
The Set Site Channel Disburse ment field sets the number of channels
assigned to the indicated T1/E1 Interface Card. Enter the number of
channels in the text box (1 - 24 for T1 or 1 - 31 for E1).
Select Slave Clock Mode
Selecting the Slave Clock Mode is p art of a higher le vel system design,
as mentioned earlier. Any system nodes that are connected using T1/E1
Interfaces must remain frequency locked at all times. The T1/E1
Interface design allows for total network synchronization through
different CEC/IMC configuration options. A detailed discussion of the
higher level system configuration is beyond the scope of this topic;
however, for a more detailed discussion refer to T1/E1 Interface
Release Notes (350A1909) and CEC/IMC Digital Audio Switch
Installation, Set-up, and Troubleshooting (LBI-38938). Select the
required clock mode from the drop-down list box.

T1/E1 Channel Assignment
T1/E1 logical channels are assigned starting with channel 1, these are
the channels used to transmit voice, data, and image signals from one
system node to another. E1 channel 1 6 is use d fo r signaling if signaling
is enabled. (See "Signaling Type" under T1/E1 Digital Site
Configuration above.) Subrate ports for user data are assigned channels
adjacent/after logical channels according to the table below.
Asynchronous (async) ports, up to 5, are assigned first and then
synchronous (sync) ports are assigned.

Subrate Port Channel Assignment
Asynchronous subrate ports require an individual channel assignment
for each port, however, up to five synchronous subrate ports can be
packed in one T1/E1 channel using DS0B subrate multiplexing. Based
on hardware considerations at the T1/E1 Interface Card, sync ports 1 - 5
and 6 - 8 would be packed in pre-assigned DS0B "sub-channels" as
shown below.

Send
Choose the Send button to send the T1/E1 site channel co nfiguration
data to the respective interface module. This procedure must be
performed before the interface module will operate with the new
configuration. Only configur ed and configured -and-active (C and C/A
prefixes) configurations may be sent. All configuration data is sent to
the MOM Controller Board; the T1/E1 configuration is sent directly out
from there to the respective interface module Controller Board. A
"Send to Site Successful" message will be received to confirm that the
data was received by the interface module Controller Board. Bus Slot
configuration data is based on the channel assignment in the Set Site
Channel Disbursement field (one b us slot per channel assigned) and is
compared to the current configuration at the CEC/IMC Manager; if
different, it is sent to the MOM Controller Board (if not, no further
action is taken by the system) and when the MOM Controller Board
receives this new data it will send an acknowledgment message back to
the CEC/IMC Manager, which will then display the confirmation box:
"Do you want to activate TDM Bus Slots? OK - will cause all CTRL
boards to reset." Choose OK to activate TDM Bus Slots (resetting
Controller Boards) with the new Bus Slot configuration data, choose
Cancel to not activate TDM Bus Slots with the new Bus Slot
configuration data (keeping the previous configuration) and return to
the Site Channel Configuration List dialog box.
Close
Choose the Close button to exit the Site Channel Configuration List
dialog box and return to the CEC/IMC Manager main window. Any

Configured/Active Sites list box will be removed and returned to the
Configurable Sites list box.
3.8.2 NIM Channel Configuration
Two or more IMC networks can be linked together for "distributed
multisite" communications using a Network Interface Module (NIM) at
each IMC switch. NIM links are communication gateways that support
a limited amount of communication traffic between network switches.
3-46
LBI-39224
Each NIM is assigned a unique site assignment number (1 thru 32)
within the CEC/IMC. This number corresponds to and matches the site
assignment number set via the 5-bit DIP switch setting on the interface
module’s Controller Board. A NIM may be either Audio Board
equipped or T1/E1 Interface Card equipped, both situations will be
discussed.
Multinode Configuration
NOTE
For this discussion the term "multinode" will be synonymous
with distributed multisite network involving multiple IMC
networks connected together by Network Interface Modules
(NIMs).
Some additional configuration considerations are required when linking
two or more IMC networks together for multinode operation. The NIM
control data link between the IMC networks must be established prior
to NIM channel audio configuration. The NIM on each end of the link
must be manually set to equal baud rates; this is performed in the
StarGate / Remote CEC / NIM Configuration dialog box as
described in DISTRIBUTED MULTISITE / STARGATE
CONFIGURATION, beginning on page 3-141. Those nodes (IMC
networks) that will make-up the multinode system must have their
Group and Unit Databases downloaded from the System Manager. This
is accomplished by downloading the System Manager Group and Unit
Databases from the System Manager as discussed in SYSTEM
MANAGER DATABASE UPLOADS, beginning on page 3-14, and
may have already been accomplished during the course of normal
CEC/IMC configuration. At the very least the Group and Unit
Database download should be verified as being complete.
The CEC/IMC ID ("switch assignment number") must be set at the
MOM Controller Board before distributed multisite (multinode)
communications will operate correctly. The CEC/IMC firmware will
automatically display a CEC/IMC ID number even if one is not set at
the MOM; therefore, a displayed CEC/IMC ID does not guarantee that
the number has been set. Ensure that this switch assignment number
has been set using the DIP switches on the MOM Controller Board as
specified in the Distributed Multisite/StarGate Configuration section of

necessary.
Add
Choose the Add button to move a selected NIM from the Configurable
Sites list box and "add" it to the Configured/Active Sites list box where
it can be selected for configuration. If upon adding a NIM, a
configuration data file exists on the CEC/IMC Manager's hard disk
drive from a previous add and delete, the NIM will be added to the
Configured/Active Sites list box with its configuration data file (with a
** prefix). This previous co nfiguration may be modified, saved, and
sent as needed.
Delete
Choose the Delete button to remove ("delete") a selected configured or
unconfigured NIM from the Configured/Active Sites list box to the
Configurable Sites list box. Configured-and-active NIMs cannot be
"deleted." This delete function does not remove NIM channel
configuration files from the CEC/IMC Manager's hard disk drive.
Therefore, if the deleted NIM is subsequently added back to the
Configured/Active Sites list box using the Add button, the previous
channel configuration is not lost (this configuration data must be resaved in the Site Channel Configuration dialog box before it can be
resent to the CEC/IMC).

Input Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) applied to the selected channel's line input. Type
the required value in the text box. The setting should b e equal to the
voice peak (test tone) level applied to the channel's line input. Voice
peak levels are +10 dBm greater than average voice levels. Valid range
is -25.0 dBm to 12.0 dBm, adjustable in 0.5 dBm increments. The
program automatically rounds-off non-0.5 dBm fractional entries to the

ALC text box to "NO."
LBI-38938 contains a line level adjustment overview section which
contains general information and general recommendations for both
input and output level settings.
Output Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) sent out by the selected channel's line output. The
setting specifies the voice peak (test tone) level sent out by the channel.
Valid range is -25.0 dBm to 13.0 dBm, in 0.5 dBm increments. Select
the required value from the drop-down list box. Output Signal Level
default = 0 dBm.
Bus/Slot Equipped
All utilized channels within an interface module must be allocated a
time slot on the CEC/IMC TDM network. Allocate a time slot to the
selected channel by setting Bus/Slot Equipped to "YES." A channel
will not route audio correctly if is not allocated a time slot. Set all
unused channels to "NO" (default setting).

Save and Send NIM Audio Board Configurations
When channel configuration of the selected NIM is complete, the
Site Channel Configuration dialog box changes must be sent to the
CEC/IMC before the changes will take effect. This reprograms the
NIM Controller Boards. However, it is important to save the new
configuration prior to sending it to the CEC/IMC because a send will
send the last configuration saved to disk; saving first ensures that the
actual CEC/IMC channel configuration will be the same as the channel
configuration stored on the CE C/IMC Manage r hard d isk. To save and
send configurations, action is required first in the
Site Channel Configuration dialog box and then in the
Site Channel Configuration List dialog box.
Site Channel Configuration dialog box
Save
Choose the Save button to perform an immediate save of the currently
selected site-type interface module's channel configuration. Other
"sites" displayed in the list box located at the top of the dialog box are
not saved. This channel configuration is saved on the CEC/IMC
Manager hard d isk drive. Any previous channel configur ation for the
"site," if present, is erased and replaced with the current channel
configuration. If the CEC/IMC Manager is running remotely or as a
part of the EDACS Network Manager, this configuration is saved on the
CEC/IMC Manager server, typically local to the CEC/IMC; it is not
saved at the remote location.
Save As...
Choose the Save As… button to allow the currently selected NIM
channel configurations to b e saved as a d iffer ent NI M. It is p ro vide d to

choosing Save As… a small dialog box (See Figure 17) will appear
which allows selection of a new NIM number. Select the desired NIM
number from one of the choices in the drop-down list box, the choices
listed are the selected NIMs in the Configured/Active Sites list box.
Like Save, Save As… stores channel configuratio n on the CEC/IMC

For example, if "Site 3" is the currently selected site-type interface
module and "Site 12" requires similar configuration settings, this b utton
may be used to save the "Site 3" configuration as "Site 12" (save to
"12"). The new "site" may then be changed later, as required, by

T1/E1 Equipped NIM Configuration
This section describes configuration for channels of T1/E1 Interface
Card-equipped NIMs. Channel configurations are performed from the
T1/E1 Digital Site Configuration dialog box, shown in Figure 18 on
page 3-39, and from the T1/E1 Interface Card Auto-configuration
dialog box, Figure 19 on page 3-42. As was the case with Audio
Board-equipped NIMs, only those NIMs selected in the
Site Channel Configuration List dialog box are available for channel
configuration.
NOTE
Like the CEC/IMC Audio Board, each T1/E1 Interface Card
within a CEC/IMC interface module must have a unique board
address setting. This address is 1 - 8 (addresses 2 - 8 are
currently not available).
NOTE
T1/E1 selection is performed at the CEC/IMC Manager on a
CEC/IMC wide basis. Changing the Line Type will cause the
complete T1/E1 database to be reset (lost). The Line Type
shown as the "default" when the Audio Interface Type dialog
box appears is how the system is configured and Line Type
should not be changed.
The T1/E1 Interface Card provides a built-in T1 or E1 port for
CEC/IMC interface modules. This port allows direct interfacing to
T1/E1 microwave, fiber-optic, or leased lines facilities. Consequently,
co-located T1/E1 multiplexing (mux) equipment at the CEC/IMC is
eliminated when the T1/E1 Interface Card is employed. CEC/IMC
Audio Boards are also eliminated within the particular interface
module. Within each of these interface modules, one or more T1/E1
Interface Cards replace all Audio Boards. The T1/E1 Interface Card
furnishes twenty-four full-duplex T1 channels in T1 mode and thirtyone full-duplex E1 channels in E1 mode. In addition to its T 1/E1 po rt,
the T1/E1 Interface Card also contains eight subrate ports which,
3-55
LBI-39224
depending upon board configuration, can provide modem-less data
links over spare T1/E1 channels to either internal or external devices.
Some, all, or none of these ports can be utilized depending on board
configuration. Five of the subrate ports support synchronous or
asynchronous data links and the remaining three are synchronous-only
ports.
T1/E1 Digital Site Configuration
Networked Systems Considerations
Any system nodes that are connected using T1/E1 Interfaces must
remain frequency locked at all times. The T1/E1 Interface design
allows for total network synchronization by offering the following
CEC/IMC Configuration options. Each of these options are selectable
by configuration of both the Clock Boards and the T1/E1 Interface
Cards.
1. Master - Redundant Clock Circuits generated by the Clock
Board in a FREE RUN mode. This allows any CEC/IMC to
become the master source of Network timing. All nodes
connected to this CEC/IMC will be in the slave mode. This
mode is established by setting the Clock Board DIP switches
to "Master" mode and all the T1/E1 Interface Cards' Slave
Clock option to "NONE."
2. T1/E1 Slave - Redundant Clock Circuits generated by the
Clock Board synchronized to 1 (or 2 with redundancy) T1/E1
Interface into the CEC/IMC. The CEC/IMC can be slaved to
an external node that is c onnected through a T 1/E1 link, and
no additional timing source is needed. Timing from the T1/E1
line is passed to the Clock Board from the T1/E1 Interface
Cards through a redundant set of synchronization clocks
named Slave A and Slave B. Each T1/E1 Interface Card can
provide Slave A, B or A&B. This mode is established by
setting the Clock Board DIP switches to "Slave to 8kHz" and 1
T1/E1 Interface Card Slave Clock option set to "SLAVE A,"
with another set to "SLAVE B" for redundancy, or 1 T1/E1
Interface Card set to "SLAVE A&B" for no redundancy.
3-56
LBI-39224
3. Slave to external 1.544 MHz - Redundant Clock Circuits
generated by the Clock Board synchronized to 1 (or 2 with
redundancy) external clock source. Any CEC/IMC can be
synchronized to the timing output from a T1/E1 multiplexer,
microwave radio, fiber network, etc. Connect the external
timing source to both Clock Boards in the CEC/IMC for
redundancy. This mode is established by setting the Clock
Board DIP switches to "Slave to Ext. 1544 kHz" and all T1/E1
Interface Cards' Slave Clock option to "NONE."
4. Slave to external 2.048 MHz (E1 mode only) - Redundant
Clock Circuits generated by the Clock Board synchronize d to
1 (or 2 with redundancy) external clock source. Any
CEC/IMC can be synchronized to the timing output from a
T1/E1 multiplexer, microwave radio, fiber network, etc.
Connect the external timing source to both Clock Boards in the
CEC/IMC for redundancy. This mode is established by setting
the Clock Board DIP switches to "Slave to 2048 kHz" and all
T1/E1 Interface Cards' Slave Clock option to "NONE."
The following configuration guidelines must be followed for network
synchronization:
1. One node in the system must be the MASTER source of
network timing. The CEC/IMC will support a primary and
redundant (or alternate) MASTER sources of timing as
indicated above.
2. A MASTER node can be defined as a site, a Jessica, a T1/E1
link, or a CEC/IMC.
3. All leased T1/E1 facilities from the telephone company are
frequency locked by the phone company. If there are any
phone company T1/E1 connections, one of the connections
must be the MASTER source of timing. Any other phone
company connections may be the redundant MASTER source
of timing. Phone company T1/E1 connections include leased
lines for sites/multinode and T1/E1 connections through an
MD110 (Jessica).
4. Any nodes using analog interfaces (including analog
connections from an MD110 to the phone company) may be
disregarded for synchronization purposes.
5. If a node is not a MASTER timing node, it must be slaved to
the T1/E1 link going towards the MASTER node.

Analog or Digital Voice
In addition to T1 or E1 selection, T1/E1 Interface Card configuration
includes selecting one of three primary board operating modes:
– Analog/modem mode ("Analog or Digital Voice using
Modems")
In the analog/modem mode, the T1/E1 Interface Card transfers
PCM-encoded signals between the CEC/IMC TDM network
and the T1/E1 line. PCM-encoded signals transferred b y this
mode include analog (clear) voice, modem-encoded digital
voice, and/or modem-encoded data signals. In this mode each
site channel is assigned to a T1/E1 channel. In addition, this
mode allows use of the T1/E1 Interface Card subrate ports if
T1/E1 channels are available after site channel assignments.
Two CEC/IMC TDM bus slots coincide to one full duplex
T1/E1 Channel. This is exactly analogous to a CEC/IMC
Audio Board channel where two TDM bus slots coincide to
one full duplex 4-wire 600-ohm audio channel provided by the
Audio Board. The T1/E1 Interface Card extracts a signal from
one bus slot and sends it out on a T1/E1 channel.
Accordingly, signals received on this same T1/E1 channel are
applied to a different CEC/IMC TDM bus slot.

Line Type
This is a read-only field which indicates which type of line (T1 or E1)
that the system is configured for.
Frame Format
Framing deals with how the digitized data stream is configured
(formatted), a data stream with one framing format would not be
recognized by a system with another frame format. The possible T1
formats are 4-Frame Multiframe (F4), 12-Frame Multiframe (F12,
D3/4), Extended Superframe (ESF), and Remote Switch Mode (F72).
The possible E1 formats are Doubleframe and CRC Multiframe. The
format is determined by the service line used. Select from the available
choices in the drop-down list box to match the line format.
Line Code
The line code indicates the method used to encode long strings of
zeroes. The receiving end of a T1/E1 link would not be able to remain
in sync if long strings of zeroes were transmitted. The possible T1 line
codes are B8ZS and AMI w/ZCS. The E1 line code is HDB3. The line
code also is determined by the service line utilized. Select from the
available choices in the drop-down list box to match the line.
Signaling Type
This signaling is used by the T1/E1 Interface Card to transmit channel
status information (busy or idle). T1 uses bits robbed from the channel
data to convey this information. E1 uses a dedicated channel to send
signaling information for all channels; therefore only 30 user channels
are allowed. In a CEC/IMC system, signaling must be set for MIM site
interfaces, and the T1/E1 muxes and base stations at the associated site
location must be configured for E&M Signaling unless the site is all
digital (no analog voice). Signaling should not be set for any other
device types. The types of signaling are No Signaling (both T1 and
E1), Robbed Bit for T1, and CAS-CC for E1. Select the signaling type
from the drop-down list box.
Line Length
This is the distance between the CEC/IMC and the device at the other
end of the T1 line, which could be a microwave transceiver, a mux in
co-located site equipment, CSU, etc. Line effects change the signal
3-59
LBI-39224
slightly, and the changes become more pronounced the further the
signal travels down the line. The outgoing original signal is modified
based upon line length so that the signal arriving at the destination
closely resembles an ideal signal. Select the line length from the dropdown list box for T1 applications. E1 applications do not support
selectable line lengths.
Set Site Channel Disbursement
The Set Site Channel Disburse ment field sets the number of channels
assigned to the indicated T1/E1 Interface Card. Enter the number of
channels in the text box (1 - 24 for T1 or 1 - 31 for E1).
Select Slave Clock Mode
Selecting the Slave Clock Mode is p art of a higher le vel system design,
as mentioned earlier. Any system nodes that are connected using T1/E1
Interfaces must remain frequency locked at all times. The T1/E1
Interface design allows for total network synchronization through
different CEC/IMC configuration options. A detailed discussion of the
higher level system configuration is beyond the scope of this topic;
however, for a more detailed discussion refer to T1/E1 Interface

selected site-type interface module's channel configuration. The
channel configuration is saved on the CEC/IMC Manager's hard disk
drive. Any previous channel configuration for the "site," if present, is
erased and replaced with the current channel configuration. If the
CEC/IMC Manager is running remotely or as a part of the EDACS
Network Manager, this configuration is saved on the CEC/IMC
Manager server, typically local to the CEC/IMC; it is not saved at the
remote location.
Send
Choose the Send button to send the T1/E1 site channel co nfiguration
data to the respective interface module. This procedure must be
performed before the interface module will operate with the new
configuration. Only configur ed and configured -and-active (C and C/A
prefixes) configurations may be sent. All configuration data is sent to
the MOM Controller Board; the T1/E1 configuration is sent directly out
from there to the respective interface module Controller Board. A
"Send to Site Successful" message will be received to confirm that the
data was received by the interface module Controller Board. Bus Slot
configuration data is based on the channel assignment in the Set Site
Channel Disbursement field (one b us slot per channel assigned) and is
compared to the current configuration at the CEC/IMC Manager; if
different, it is sent to the MOM Controller Board (if not, no further

action is taken by the system) and when the MOM Controller Board
receives this new data it will send an acknowledgment message back to
the CEC/IMC Manager, which will then display the confirmation box:
"Do you want to activate TDM Bus Slots? OK - will cause all CTRL
boards to reset." Choose OK to activate TDM Bus Slots (resetting
Controller Boards) with the new Bus Slot configuration data, choose
Cancel to not activate TDM Bus Slots with the new Bus Slot
configuration data (keeping the previous configuration) and return to
the T1/E1 Interface Card Auto-configuration dialog box.

3.8.3 PIM Channel Configuration
The interface between the CEC/IMC and a Jessica PBX Gateway
system, known simply as Jessica, is provided by the Private Branch
eXchange (PBX) Interface Module (PIM). A PIM can provide up to
32 channels for Jessica PBX systems. The PIM consists of a Controller
Board and up to eight Audio Boards or T1/E1 Interface Cards.

Configurable Sites:
The Configurable Sites list box displays all inactive unconfigured sitetype interface modules. If a PIM appears in this box, no channel
configuration exists at the CEC/IMC Manager and no active Controller
Board control data link exists at the CEC/IMC for the corresponding
site assignment number. Any number of these available PIMs may be
selected at one time to be assigned to the Configured/Active Sites list
box for configuration.
Configured/Active Sites:
The Configured/Active Sites list box displays PIMs which have been
added but not yet channe l-configured, PIMs which have had p revious
channel configurations performed, and PIMs which have been
previously channel-configured and have an active Controller Board
control data link. Before a PIM can be channel-configured, it must be
listed in the Configured/Active Sites list box. Any number of these

available PIMs may be selected at one time for modification in the
Site Channel Configuration dialog box. All selected PIMs in this list
will also be included in the "Save As…" dialog box that is accessed
from the Site Channel Configuration dialog box or the
T1/E1 Digital Site Configuration dialog box. If necessary, refer to
Configured/Active Sites Prefix Definitions, Table 1, on page 3-25 for
an explanation of the prefixes.
Add
Choose the Add button to move a selected PIM from the Configurable
Sites list box and "add" it to the Configured/Active Sites list box where
it can be configured. If upon adding a PIM, a configuration data file
exists on the CEC/IMC Manager's hard disk drive from a previous add
and delete, the site will be added to the Configured/Active Sites list box
with its configuration data file (with a ** prefix). This previous
configuration may be modified, re-saved and sent as needed.
Modify
Choose the Modify button to display the Audio Interface Type dialog
box, select either Audio Board or T1/E1 Interface as required by
clicking the appropriate option button. Selecting Audio Board will
activate the Site Channel Configuration dialog box, selecting T1/E1
Interface will activate the T1/E1 Digital Site Configuration dialog
box. These options are discussed in detail in subsequent sections.
Delete
Choose the Delete button to remove ("delete") a selected configured or
unconfigured site from the Configured/Active Sites list box to the
Configurable Sites list box. Configured-and-active sites cannot be
"deleted." This delete function does not remove "site" channel
configuration files from the CEC/IMC Manager's hard disk drive.
Therefore, if the deleted "site" is subsequently added back to the
Configured/Active Sites list box using the Add button, the previous
channel configuration is not lost (this configuration data must be resaved in the Site Channel Configuration dialog box before it can be
resent to the CEC/IMC).

LBI-39224
View Current CEC/IMC Channel Configuration
The lower list box in the Site Channel Configuration dialog box,
labeled "CEC/IMC," displays the current channel configurations stored
at the CEC/IMC for the currently selected site-type interface module.
Information within this box updates only after Send is performed from
the preceding Site Channel Configuration List dialog box.
CEC/IMC to Disk
Choose the CEC/IMC to Disk button to write the current CEC/IMC
configuration data to the CEC/IMC Manager hard disk. This action
will overwrite the current CEC/IMC Manager configuration for the
selected interface module. This function is useful if the CEC/IMC
Manager configuration database is lost for any reason. A difference
between CEC/IMC and CEC/IMC Manager databases will be evident
by comparing the CEC/IMC Manager and CEC/IM C list boxes in the
Site Channel Configuration dialog box. Ensure that the CEC/IMC
configuration is correct, then choose the CEC/IMC to Disk button to
restore the CEC/IMC Manager configuration database for the selected
interface module.
Channel Selection
Select a channel (1 thru 32) for configuration from the CEC/IMC
Manager channel list box, only one channel may be selected at a time.
The selected channel and its configuration data will be displayed in the
edit fields above the CEC/IMC Manager list box.
Input Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) applied to the selected channel's line input. Enter
(type) the required value in the text box. The setting should b e equal to
the voice peak (test tone) level applied to the channel's line input.
Voice peak levels are +10 dBm greater than average voice levels.
Valid range is -25.0 dBm to 12.0 dBm, adjustable in 0.5 dBm
increments. The program automatically rounds-off non-0.5 dBm
fractional entries to the nearest 0.5 dBm. Input Signal Level default =
0 dBm.
3-68
LBI-39224
NOTE
If Automatic Level Control (ALC) is disabled for the selected
channel, subtract 1.5 dBm from the required Input Signal
Level setting. For example, if the required input signal level is
-10 dBm, enter -11.5 dBm. ALC is disabled by setting the
ALC text box to "NO."
LBI-38938 contains a line level adjustment overview section which
contains general information and general recommendations for both
input and output level settings. For PIMs, refer to system manual
EDACS Jessica PBX Gateway, LBI-39000, for PIM input and output
level setting information.
Output Signal Level (dBm)
This setting establishes the signal level in dBm (600-ohm impedance;
0 dBm = 1 milliwatt) sent out by the selected channel's line output. The
setting specifies the voice peak (test tone) level sent out by the channel.
The valid range is -25.0 dBm to 13.0 dBm in 0.5 dBm increments.
Select the required value from the drop-down list box. Output Signal
Level default = 0 dBm.
Channel Signaling
For a PIM Channel Signaling should always be set to "NONE."
Secure Tone
The Secure Tone setting is not utilized for PIM site-type interface
modules as Channel Signaling should always be set to "NONE."
Bus/Slot Equipped
All utilized channels within an interface module must be allocated a
time slot on the CEC/IMC TDM network. Allocate a time slot to the
selected channel by setting Bus/Slot Equipped to "YES." A channel
will not route audio correctly if is not allocated a time slot. Set all
unused channels to "NO," (the default setting).
3-69
LBI-39224
NOTE
In earlier CEC/IMC firmware/software releases, slot
allocations could only be made contiguously starting with
channel one (1). In some systems this produced slot allocation
inefficiencies—some slots had to be allocated but were never
used. CEC/IMC software/firmware release 5.0 (and later)
provides non-contiguous slot allocations. In this release, only
those slots actually required need be allocate. For example,
channels 1 and 4 can be allocated slots without allocating slots
to channels 2 and 3.
Notch Filter
Do not enable the notch filter on any utilized channel for a PIM,
therefore set Notch Filter to "NO" (disabled).
ALC
CAUTION
DO NOT enable ALC for any channel if the respective Audio
Board part number is 19D903302P1 (any revision).
Automatic Level Control (ALC) provides compensation for signal level
variances in a channel line input signal. As required, enable ALC for
the selected channel by entering "YES" in the ALC text box or disable
it by entering "NO."
Save and Send PIM Audio Board Configurations
When channel configuration of the selected PIM is complete, the
Site Channel Configuration dialog box changes must be sent to the
CEC/IMC before the changes will take effect. This reprograms the
PIM Controller Boards. However, it is important to save the new
configuration prior to sending it to the CEC/IMC because a send will
send the last configuratio n that was saved to disk; saving fir st ensures
that the actual CEC/IMC channel configuration will be the same as the
channel configuration stor ed on the CEC/IMC Mana ger hard disk. To
save and send configurations, action is required first in the
Site Channel Configuration dialog box and then in the
Site Channel Configuration List dialog box.
