tabletop or other level surface. First though, make sure the desired surface can support the
weight of a chassis.
2-2 System Installation
Page 29
System InstallationChassis Installation
Be sure to locate the system near all external equipment to which you will connect it. Cable
lengths and physical/electrical characteristics are critical to system operation, especially for
data signal interfaces. Generally, higher data rates require shorter cables than lower data rates.
Also, you must use T1-grade cables for all system connections to those networks. For best
results, use the cables supplied by your supplier when connecting your system to the
associated external facilities. For more information on system cabling, call your supplier.
2.2.3.1Rack Installation Tips
When installing the chassis in a rack, allow at least 2 inches (5.1 cm) of space between the
chassis and the equipment in front and behind it for proper ventilation. Use the mounting
brackets and attachment hardware furnished with the chassis for this purpose, as outlined in
this chapter. If you use other mounting hardware, you may damage the chassis or circuit
boards installed in it.
Also route all cables to their destinations through conduits to enhance electromagnetic
compatibility (EMC) per formance and facilit ate future system troub leshooting. When ro uting
cables, be sure not to obstruct any chassis vents.
2.2.3.2Tabletop Installation Tips
The chassis can be pl aced on a flat, s moot h surf ace ( e.g., a tab le) tha t is free of con taminan ts .
This surface should be capable of supporting the chassis.
If you are placing the chassis on a tabletop or other flat surface, be sure to leave enough
clearance for a ir circulati on throug h the syste m. Make sure the chassis is accessibl e from both
the front and rear.
2.2.4Installing the Chassis
Figure 2-1 shows the front panel of the IMACS-200 chassis. To mount the chassis in a rack,

2.4.8Connecting Cables to the ports
Connect system ports to the external equipment, using the proper cables. The ports have
various types of connectors for those connections.
Voice ports have a 50-pin Amphenol-type jack. To connect a cable to this type of jack, first
plug the male connector of the ca ble into t he jac k and push it in a ll th e way. Then, tighten the
mounting screws on either end of the cable connector shroud to the IMACS-200 connector.
For modular (RJ-45) jacks, push the cable’s mating plug into the ja ck until it sna ps in to place .
However, do not try to force th e plug into t he jack.
For DB-25 jacks, first plug the cable’s mating connector firmly into the jack. Then, thread the
screws on either s ide of the ca ble connector shroud into t he standof fs on eit her side of t he port
jacks, and hand-tighten them.

2.5.1Power Supply and Ringing Generator
The power supply and ringing genera tor syst em can consi st of up to two power supp lies, and
has one on-board ringing generator. The IMACS-200 comes with the proper power supplies
factory-assembled depending on the ordering information provided at the time of purchase.
2.5.1.1Ringing Generator
The Ringing Generator on the IMACS-200 outputs 86Vrms at 20Hz. That is the output if
ringing into a 1 to 4 REN load. If the load increases, the built-in overload protection will
reduce the output voltage in steps as shown in Table 2-11.
This ability inherent i n the IMACS-200 provides cont inuous service up to 12 North American
REN loads without distortion.
Following is more detailed information regarding the power inputs.

2.5.2System Power (Redundancy)
The IMACS-200 provides power redundancy for any of the powering options. The supplies
are factory-in stalled, and t he external co nnectors to re ceive the power ing options sel ected will
be pre-installed on t he unit. Figure 2 -4 on page 2-5 high- lites the locati on of the Power Suppl y
feeds.The 120VAC and 220VAC power inputs are lightly shaded, and the -48VDC and
125VDC options are darkly shaded.
2.5.3AC Power Supply and DC Power Supply Fuses
The AC power supply and DC Power Supply fuses are alread y bui l t i n t o t he supplies. These
fuses are not field servi ceable. When unpacki ng the unit, an AC power cord will be in the box
for each of the AC power supplies ordered. The AC inlet connector is located in the rear
corners of the chassis. For a single supplied unit, the rear right-hand connector will be
equipped. Refer to the system specifications section in this manual for input power
requirements.
2.5.4System Power and Ground Connections
After installing the system, make the power and ground connections to the chassis as
described in this s ection. A frame gr ound connection i s provided in th e right-rear corner of the
IMACS-200 rear panel.
2.5.5Grounding requirements
Due to the UL regula tory re quiremen ts, a mounting stud is requi red f or con necti on of t he AC
input earth ground lead to the product chassis. The ground lead must be connected to the
chassis using a No. 6 screw, which is included. When grounding the system, use 14 gauge
solid wire for a single connec tion to the provi ded eart h grou nd screw. The mounting location
is labeled with the IEC 417 No. 5019 symbol to identify this as the AC earth ground
connection point. This mounting stud is located next to the IEC 320 AC input connector.
2.5.6Chassis with Power Supplies
Figure 2-4 on page 2-5 shows the different power connections on the chassis.
For DC powered systems, the lower right and lower left-hand connections provide for
separate, redundant power feeds to the system's pre-installed DC power supplies if so
equipped. These two sets of leads provide a connection for separate, redundant power feeds
to the system in a load-sharing mode.
2-14 System Ins t allation
Page 41
System InstallationPower and Grounding on the IMACS-200
The telecommunications voice signaling ground is a referenced ground connection to the
-48VDC power system. Both feeds are referenced to the same place within the IMACS-200.
This reference ground can occur at the -48VDC power source. If the ground connection is
not maintained, and one side of the connection equipment is not referenced to an earth
ground then a floating ground condition can occur causing the voice circuits and the
voice signaling to react erratically when either end of the connecting equipment tries to
start the circuit.
Sites using only lo op start telecommu nication circu its (no ground star t or E&M signaling) ca n
operate properly without the Telecom Signaling Ground.
When grounding the system, use 14 gauge solid wire for a single connection to the provided
earth ground screw.
For AC powered systems, t he right and left -hand con nections provide f or sep arate, re dundant
power feeds to the system's pr e-install ed AC power supplies if so equ ipped. These two sets of
leads provide a connection for separate, redun dant power feeds to the syste m in a load-shar ing
mode.
2.5.7DC power instal l atio n
When wiring to an exter nal power source, such as a batte ry rack, fuse pa nel, or circuit breaker ,
make sure that the correct rating of wire is used . Figure 2-5 illustrates the DC power plug. It
is recommended that you use 20 to 18 gauge solid wire.
Figure 2-5. DC Power plug
When the IMACS-200 is ordered with a si ngle-power supp ly unit, the IMACS-200 will come
with the power supply installed on the right-hand rear of the box, closest to the T1/E1 ports
and grounding screw. Insert the power plug illustrated above into this right-hand rear
connector.

to the unit, simply use the supplied AC cords included in the packaging to connect the
IMACS-200 to the 120VAC or 220VAC source.
2.5.9Powering Up the System
After connecting the chassis to the external power sources and making the proper ground
connections, apply p ower to the chassis. Plug the AC power cord int o the assoc iated elec trical
outlets, or turn on the external DC power supply. Then, observe the following front-panel
LEDs:
1. On start-up, all LEDs on the front and rear of the unit cycle through the following color
sequence:
Orange, Green, Red and blank.
2. The POWER LED then wil l turn gr een on the chassis faceplat e. The ACTIVE LED will
stay orange until the unit boot cycle is completed, and then turn green.
If no LEDs illuminate, verify that the external power source is providing power to the chassis,
and check the connection between that source and the chassis.
Once power is confirmed, the user in terface sh ould appear. If not, simply hit carr iage return.

System Configuration and Operation
3.1Basic Operations
This chapter provides instructions for configuring the IMACS-200 for operation after
installing it at the equipment site.
Before performing the procedures in this chapter:
1. Be sure your IMACS-200 is installed and powered up.
2. Determine your system’s specific configuration requirements. These depend on your
network and customer premises equipment (CPE) interfaces. If this configuration
information already exists, obtain it from your system administrator or engineers.
3. Obtain a terminal with VT-100 or VT-102 emulation and an RS-232 to RJ45 serial cable
for these procedures. The terminal will be connected directly to the SERIAL port on the
front faceplat e of your system. T his will allow you to access the system and t hen configure
it for operation with your network and CPE.
Refer the Table 2-10 on page 2-11 for pinouts for RS-232 and SERIAL port.
3.2Basic Screen Map and Legend
To make system access, configuration and testing easy, the system presents you with a series
of user interface screens. Each screen displays various fields of information, and you can
change the data in those fields as required by your system and external interfaces.
3.3System Power -up
The IMACS-200 system will initialize when it is powered up. The normal sequence for
initialization and login are described on the following pages.

From the System Main Screen, you can also access other screens, as shown in Figure 3-5.
These screens are described in the following paragraphs.
3.4.3Service Type Main Screens
Each port type in the system has a port Main Screen associated with it. You can go from the
System Main Screen to any port Main Screen and configure that device. From a port Main
Screen, you can access a Test Screen to perform tests on the port, or (in some cases) a
Performance Monitor Screen to view transmission performance data.
Figure 3-5 shows the main scree n of t he IMACS-2 00 and refle cts the port stat us. On t he FXS
line, the user will note the four different ports, and that each port is in a different state. Port
one is on the left, and port fou r is on the ri ght. The figur e dis plays ‘aslt’ as the status of ports
one through four, which are: port 1 is in active state. Port two is in standby state, which is to
say it is out of service.Port three is in the loopback active state, in other words it is currently
involved in a user-initiated maintenance mode. And finally port four is in a test state, which
is a user-initiated testing mode. These states are used commonly on all the different service
types, and are a quick reference for the status of each port.
Figure 3-6 shows a typical port Main Screen. The highlighted line at the top of every screen

safe place where they can be readily obtained.
You can also record screen settings by “capturing” each edited screen onto your computer
terminal while you a re logged into the system. To do this, your comput er must have a software
program capable of capturing the actual screens as text files. The communications software
you use to access the system may have this ability. You can then copy the screens to a word
processing program, print them out, and / or store them electronically.

3.7.2Alarm Filter Settings
Y ou can set filt ers for each alarm so t hat the alarm r eports occu rrences in a number of dif ferent
ways. Figure 3-11 shows the Alarm Fil te rs scr ee n, whi ch i s a cce ss ed by pressing "f" (Filters
command) on the Alarm Screen.
Figure 3-11.Alarm Filters Screen
The first column of th e Alarm Filters Screen is the alarm abbreviation that appears when an
alarm is generated. The second column is the associated full name of each alarm. Table 3-2
describes each alarm appearing in the Alarm Filters Screen.
The third column contains the filters ignore, log, and report. Set the filter to ignore if you
want the system to ignore the alarm. Or, set it to log if you want the system to show the alarm
report on the screen and also log it in to the Alarm History, as described later in this cha pter.
Set the filter to report if you want the system to send (report) the alar m indication to a remote
device. Wi th this se ttin g, the syste m will also di splay the alarm re port on the screen and l og it
into the Alarm History.
The fourth column of th e Alarm Filters Screen contains the filter modifiers info, mi nor, major, and crit. This column specifies a le vel of i mport ance ( informa tion o nly, minor alarm,
major alarm, or critical al arm) for eac h alarm. These settings are described la ter in thi s chapter .
The last column sets the alar m cutoff (ACO) to aco-off or aco-on. These settings are explai ned
later in this chapter.
The filter in the thi rd col umn take s prece den ce over its modi fier. If, for instance, you have a n
alarm filter set to ignore, the setting of the modifier as info, minor, maj or, or crit will be
ignored. Refer to system specifications section in this manual for alarms and their meanings.

3.10Time Slot Assignment
This section provides instructions for assigning DS0 time slots to the voice and data ports of
the IMACS-200. It also provides time slot cross-connection setup instructions.
System Operation3-25
Page 68
Running Head
Assigning Time SlotsSystem Configuration and Operation
The IMACS-200 maximizes the use of incoming and outgoing T1 lines. You can do this by
assigning specific c hannels , or DS0 t ime sl ots , to voice and da ta por ts i n the syst em. You also
can cross-connect time slots between T1WAN ports of the system.
The WAN port allows you to connect one DS0 time slot to another. Throughout this chapter,
these connections ar e called "pas s-through" ci rcuits becau se they link a ti me slot from one T1
line to another thro ugh the syste m. You can therefore have up to four separ ate T1 links on two
WAN ports, in any cross-connect combination.
The following sections of this chapter describe several ways for you to administer your
networks and correctly al locate tr ansmission bandwidth to meet your needs. The nex t section
deals with assigning time slots to the user voice and data port.
The third section deals with cross-connecting WAN time slots to other WAN time slots.
The fifth section describes signaling status, signaling, and companding conversion. The last
section shows you how to view the time slot map after making your assignments and
cross-connections.
Model No.
This chapter defines "assigning time slots" as the process of connecting user port ports to
WAN ports and time slots, and it defines "cross-connecting time slots” as the process of
connecting WAN time slots to other WAN time slots in the system.
3.10.1Modes of Operation
In the 1.x.0 system, the only mode available is XCON.
3.10.2XCON Mode (XCON)
The XCON mode allows the user to cross-connect DS0s to user voice or data ports or to
cross-connect any DS0 on any WAN port to any DS0 on any other WAN port in the system.
The “Mode” setting on a WAN in a XCON system will only indicate the XCON option.
3.11Assigning Time Slots
You must use a time slot map to specify the connections between all incoming and outgoing
lines connected to the system. The time slot map lets you split up your T1 bandwidth into
portions required for normal voice and data communications. It contains the connections for
all ports in your system.

3.11.1Assigning a Time Slot to a User port Port
You can define a time slot map from any user port (data or voice) for connections involving
that port, or from a WAN port for cross-connect ions involving only WAN ports. For example,
Figure 3-16 shows the E&M por t Main Screen for the time slot assignments. Assign t ime slots
to a voice port as follows:
1. From the System Main Screen, select the desired voice port and press <Enter>. That
port’s Main Screen appears.
2. Select the WAN port from which you want to assign time slots to the E&M port. In
Figure 3-16, this is wan-1 (for WAN 1, port 1).
3. Select a tim e slot (TS) for the first port. A number appears at the bottom of th e screen
for the corresponding time slot on the WAN port.
4. Set the time slot number by usi ng the up and down arrow keys to hi ghlight it, then press
the <Enter> key.
5. Change the STATE of the port from stdby to actv.
6. Repeat steps 2 through 5 for the remaining port ports, to assign time slots to them.

System Configuration and OperationCross-Connecting WAN Time Slots
SIG/TC
You can define a pattern to be transmitted on a cross-connected circuit if one of the circuit’s
two WAN links fails on a WAN to WAN cross-connect. This is known as T runk Condit ioning
(TC), and can be assigned for the transport channels. For circuits that terminate locally in the
IMACS-200, the field is populated as n/a, for not applicable.
The SIG/TC choices are shown in Fi gure 3-28. The off optio n turns of f all trunk condi tioning
and signaling off for the selected circuit, creating a clear-channel path. The other available
options will enab le robbed-bit s ignaling for t he cross-conne cted circuit: user (user- defined bit
pattern), e&m (trunk signaling), fxsl (foreign exchange station-loop-start), fxsg (foreign
exchange station ground-start), fxsd (foreign exchange station-defined network), plar
(private-line automatic ringdown), dpo (dial-pulse originating), fxol (foreign exchange office
loop-start), fxog (foreign exchange office ground-start), fxod (foreign exchange
office-defined network), dpt (dial-pulse terminating) and mrd (manual ringdown). The screen
below has been modified to display all the possible opti ons.

Once a service has been selected on the SIG/TC screen, you will then need to select the idle
or busy patt ern to send on a CGA event. On the exampl e shown below in Figure 3-30, for t he
timeslots chosen for WAN-3 and WAN-4 connection, a busy signal will be sent to the DS0
identified on WAN-4 should WAN-3 fail, and conversely an idle pattern will be sent should

4.3.2User Names, Passwords and Groups
You may want to change your system access passwords frequently, in order to maintain
optimum security on you r network. The recommended pa sswords are a minimum of 6 and no
more than 12 characters in length, are not found in a dictionary, and contain both letters and
numbers. Because the system is case-sensitive for password entries, you can mix uppercase
and lowercase letters to provide more possible passwords.
The user administration fun ction is activated by enter ing ‘n’ for usrNames from the CPU Main
screen, as shown in Figure 4-2 on page 4-2.
Note:The passwords MUST be at least six char acters long an d MUST be a c ombination of
characters and at least one digit!
The system supports 256 possible users. Each user is defined by the use of three entries or
fields. The fields are edi table by a user who has Admi nistrator or Superu ser access. Following
is a brief description to the user fields:

4.5SNMP Network Management
SNMP access allows users to remotely gather information, provision, test and monitor the
IMACS 200. This section presents this type of Network Management System (NMS) for
diagnosing and reporting trouble at unsupervised locations. The SNMP alarm traps and
configuration can connect using thi s alternate method. Both formats can use either the SA4 on
an E1 link, or a full DS0 on a T1 or E1 link.
If you do not understand the NMS concepts of IP addressing, SNMP, TELNET, and Ping,
please consult with your network administrator before attempting to install or repair
components presented in this section.
The first step in starting an operator session is to log into the system. You must enter a
password that allows you to perform the required tasks on the system. The initial (default)
SNMP Default Passwords / Community Names correspond to four different access levels,
each allowing you to perform cer tain tasks. T able 4-7 li sts the default passwor ds and describes
the access levels.

the other levels below it. For example, if you log in under the “Operator” password, you can
configure the system and perform di agnostic t ests, or y ou can simply view the current syst em
status and configuration data, which are the only tasks permitted under the “Viewer”
password.
All passwords are case-sensitive for maximum security. For example, the system handles
