System Overview Introduction

Chapter 1 System Overview

1.1 Introduction

This chapter describes chassis used by the IMACS-200.

The IMACS-200 is availabl e wit h re dundant power supplies which oper at e i n a lo ad-sharing mode.

The IMACS-200 chassis is manufactured to be RoHS-compliant.

The IMACS-200 comes “Industrial hardened” to operate und er more extreme temperature ranges of -40 degrees Cel sius to +70 degrees Celsi us (-104 degrees Fahrenh eit to +158 degrees Fahrenheit).

1.1.1 IMACS-200 Chassis

This chassis is desig ned for table t op, wall or rac k mounting. All voice and data po rt acces s is from the rear of t he chassis. The craf t int er face and alarm indi cat io n LEDs ar e located on the front of the IMACS-200 unit, as seen in Figure 1-1. The IMACS-200 features an on-board ringing generator.

Figure 1-1.IMACS-200 Front Panel

The power supply of fering with the IMACS-200 comes with either one or two powe r supplies. One power supply is capable of handling all the power needs for the unit. When ordering a unit with a redundant p ower supply, the IMACS-200 operates i n a load sh aring mo de. Should one of the two units fail, the other unit will immediately take over powering of the IMACS-200.

Introduction System Overview

The IMACS-200 offers a range of power input options, which are selected to be the most commonly used input voltages in use by our various customers . They are: -48VDC, 125VDC, 120VAC and 220VA C. The power supply modules are factory installed, and will come with the proper connectors configured for the IMACS-200 powering options you have selected. The power inputs are to the right and left rear of the IM ACS-200, and label ed according ly. In Figure 1-2, the supply inputs are seen on the sides of the rear panel.

Figure 1-2.IMACS-200 Rear Panel

Notes:

1. The two -48VDC and 125VDC feeds are located in the lower-left and lower-right hand corners of the IMACS-200 rear panel. Based on ordering options, these ports will arrive at the customer site with screw-down terminals contained in an accessory bag in the IMACS-200 packaging. For cus tomers who order the single- supply option, the ri ght-hand connector above (nearest the T1/E1 and ground screw) should be used. These three-pin terminals (if s o equip ped) ar e labe lled left- to-r ight a s NC ( No Connect ion), -48 or 125 a s the case may be, and RTN (return).

2. The two 120VAC and 220VAC feeds are located in the upper-left and upper-right hand corners of the IMACS-200 rear panel. Based on ordering options, these ports will arrive at the custo mer site with AC jacks installed. Simply place a North-American AC po wer supply cord into the supplied jacks.

3. The IMACS-200 comes with two fan units installed in the unit. These fans will turn on and off automatically as the temperature fluctuates inside the enclosure. These fans are not field serviceable, and will alarm should one of them fail or become obstructed.

A more detailed descrip tion of this chassis and its power ca pabilities is given in chapter 3.

System Installation Introduction

Chapter 2 System Installation

2.1 Introduction

This chapter provi des inst ruction s for unpa cking and i nstall ing the I MACS-200 chassi s at the user site. It also includes other information you will need to properly install the system and refers you to other chapters for additional port-level information.

The system can operate on either AC or DC power when equipped with the proper power supply. Refer to the system specifications section in this manual regarding

electrical and

environmental requirements.

2.2 Chassis Installation

2.2.1 Unpacking the Chassis

When you receive your system , unpack the box and chec k the contents for da mage. Inside the box you should have the following three items:

1. The IMACS-200 system

2. A CD ROM with the documentation for the latest or ordered release.

3. A poly bag including the mounting hardware and power cord(s) and or connector(s).

If any of the items above are missing, please contact your sales representative. If anything is damaged, contact the shipping carrier to file a claim. The carrier representative will also tell you how to submit a claim, where to s end t he unit, and give you any specia l i nst ruc ti ons you may need.

Pack the damaged item in its original packing materials and send it by prepaid freight to the address you received. If the original packing materials are unavailable, pack the unit in a sturdy box and surround it with shock-absorbing material.

2.2.2 Pre-Installation Tips

2.2.2.1 Installation Checklist

Install your IMACS-200 in the following sequence:

1. Choose a suitable location for the system, as described in this chapter.

2. Unpack and inspect the equipment for damage.

3. Mount the chassis on the desired surface (rack, tabletop, or wall).

4. Install the chassis ground connections.

5. Verify the voltage ratings of all power supplies in the chassis.

6. Verify the fuse ratings of the source power supply.

7. Apply power to the system and verify the power LED states.

After successfully installing the system, configure the system for operation as follows:

1. Connect a VT100-compatible terminal to the Interface port.

2. Log into the system.

3. Set the Alarm Filters.

4. Configure the CPU interface along with the ethernet port if desired.

5. Configure the Voice ports.

6. Configure the Data ports.

7. Configure the WAN ports.

8. Configure all other ports.

2.2.3 Choosing a Location for Your System

The IMACS-200 requires a re asonably dust-free , static-free ope rating environment. Adeq uate ventilation is also req uired at the sit e. Do not inst all t he chass is in direct sunli ght, which may increase the system’s operating temperature and affect its operation.

Most of the system plug-in por ts have hig hly sens itive compo nents that could be damage d by static electric ity. Whenever you handle any system p orts, be s ure to obse rve local electrost atic discharge (ESD) precautions.

The system chassis can be installed on an 19-inch or 23-inch equipment rack, or placed on a tabletop or other level surface. First though, make sure the desired surface can support the weight of a chassis.

System Ins t allation 2-3

System Installation Chassis 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.

2.2.3.1 Rack 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.

2.2.3.2 Tabletop 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.

2.2.4 Installing the Chassis

Figure 2-1 shows the front panel of the IMACS-200 chassis. To mount the chassis in a rack, first attach the brackets to the sides of the chassis, using the four associated 10-32 x 1/4” screws. The brackets are reversible for mounting in 19-inch or 23-inch racks (48.2 or 58.4 cm). For a 19-inch r ack, at tach t he lo ng s ides o f the bracke ts to the ch ass is (F igure 2-2 sho ws the mounting brac ket s and holes). For a 23-inch rack, att ach the short si des of t h e br ac ket s to the chassis. You can attach the brackets to either positi on on the side of the ch assis. See Figure 2-3 on page 2-5 for a view of t he side panel of the IMACS-200 .Then, use the f our 12-24 x 1/ 4” screws to mount the bracketed chassis on the rack.

2.5 Power and Grounding on the IMACS-200

2.5.1 Power 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.

2.5.1.1 Ringing 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.

2.5.2 System 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.

2.5.3 AC 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.

2.5.4 System 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.

2.5.5 Grounding 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.

2.5.6 Chassis 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.

System Ins t allation 2-15

System Installation Power 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.

2.5.7 DC 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.

If ordered as an AC unit, the IMACS-200 will come pre-assembled with one or two AC connectors on the rea r panel , a s illust rate d in Fi gure 2- 4 on page 2- 5. To apply the AC source to the unit, simply use the supplied AC cords included in the packaging to connect the IMACS-200 to the 120VAC or 220VAC source.

2.5.9 Powering 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. A window like Figure 2-6 should appear. Type i n the user n ame of “admin”, and t he password is “admin”.

3.1 Basic 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.

3.2 Basic Screen Map and Legend

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.

3.5.2 Recording Your Configuration Settings

You should always record the configuration option settings for each port after you set them. This information may be needed later for system operation. To record the port configuration data, first photocopy the pages showing the port Screens in the associated chapters of this guide. Then, mark the opti on setti ngs you want to use on those p ages, and st ore the page s in a 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.

3.6 Reinitializing the System

The system stores in formation about i ts currently inst alled ports, the port configura tion option settings, WAN connections, passwords, and other data in nonvolatile memory (NVRAM). When you change any settings on the port types, the NVRAM remembers the previous port settings.

Restart capability is available on the IMACS-200. If the user desires to restart the IMACS-200, capability is available on the main login screen with the Oos command. This command will restart the box, as shown in Figure 3-7. preserving all provisioned data.

Figure 3-7.Rebooting the IMACS-200

If you have redeployed the IMACS-200, or otherwise desire to re-initialize the unit to the default settings, you c an “zip” it , causing it to be reprog rammed. From the main login scre en, enter ‘Y’ to go to sYstem. A screen such as what is seen in Figure 3-8 appears

Since the user names and passwords are maintained over the zip function, the user will be able to login as normal. Also maintained over the zip function are the IP address(es) saved in the unit.

3.7 Alarms

Alarms warn you of problems by reporting possible system hardware or external facility failures. The Alarm scree n is accesse d from the System Mai n Screen by press ing the "A" key to go to the Alarm Scr ee n ( se e Fi gur e 3-10 through Figure 3- 12) . The Al arm Screen displays the currently activ e alarms (if any) and p rovides access to th e Alarm Filters and Ala rm History screens. Figure 3-10 shows a typical Alarm Screen with an active alarm.

3.7.1 Alarm Screens

Refer to Figure 3-10. To view the current system alarms, you ca n go from the System Main Screen to an Alarm Screen. From the Alarm Screen, you can then go to an Alarm Filters Screen and set up the alarm reporting filters. Or, you can access an Alarm History Screen (log) and view alarms that we re previou sly logged by the sy stem. These sc reens and o peration s are discussed in the “Alarm s and Alarm Filters” section later in this chapter.

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.

Usually receiv ed when the device loses WAN signal or synchronization.

AIS Alarm Inform ation Signal The system has received a Blue Alarm signal f rom a remote device. Usually

received when the remote or intermediate device has a major failure.

CGA_RED Carrier Group Alarm - Red The local incoming WAN signal has a serious problem and trunk

conditioning is started. After receiving a RED alarm (NOS or LOS) for 2-3 seconds, the system initiates the appropriate trunk conditioning sequence (see voice ports for information about the TC_CGA setting) and sends a Yellow Alarm to the remote device. If the system is in drop/insert mode, it also sends an AIS signal to the downstre am equipment.

CGA_YEL Carrier Group Alarm - Yellow The system has initiated trunk conditioning in response to a Yellow Alarm

from a remote device. After 2-3 seconds, the system initiates the appropriate trunk conditioning sequence (see voice ports for information about the TC_CGA setting).

ERR Excessive Error Rate The error rate measured by the system has exceeded the threshold set on the

WAN port.

Assigning Time Slots System 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.

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.

3.10.1 Modes of Operation

In the 1.x.0 system, the only mode available is XCON.

3.10.2 XCON 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.

3.11 Assigning 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.

3.11.1 Assigning 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).

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).

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!

SNMP Network Management IMACS-200 General Features

4.5 SNMP 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.

Table 4-7. SNMP Users and Default Passwords

The “Superuser” p assword is the highest level of access, f ollowed by “Man ager”, “Opera tor”, and “Viewer” in sequence. Each level allows you to also perform all operations available to 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

TechMan, TECHMAN, and Techman as three different passwo rds .
