Safety Instructions

Important Safety Instructions

1.Read and follow all warning notices and instructions marked on the product or included in the manual.

2.This product is intended to be used with a three-wire grounding type plug - a plug which has a grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by modifying the plug or using an adaptor.

Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the presence of earth ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician has corrected the problem.

If a three-wire grounding type power source is not available, consult a qualified electrician to determine another method of grounding the equipment.

The dc configuration of this product is to be grounded by connecting an external wire between the building ground and the equipment ground screw on the rear of the power supply assembly. Consult a qualified electrician to ensure that the ground connections are connected.

3.Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from overheating, these slots and openings must not be blocked or covered.

4.Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the power cord.

5.Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel.

6.General purpose cables are provided with this product. Special cables, which may be required by the regulatory inspection authority for the installation site, are the responsibility of the customer.

7.When installed in the final configuration, the product must comply with the applicable Safety Standards and regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

8.A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action prior to interconnecting the products.

In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:

±Never install telephone wiring during a lightning storm.

±Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

±Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

±Use caution when installing or modifying telephone lines.

±Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning.

±Do not use the telephone to report a gas leak in the vicinity of the leak.

Overview

AT&T Paradyne offers the COMSPHEREr 3000 Series Carrier, Figure 1-1, assembly to support

high-density mounting of the following AT&T Paradyne products in a central-site environment:

•Model 3151 Channel Service Units (T1 CSUs)

•Model 3161 Data Service Units/Channel Service Units (T1 DSU/CSUs)

•Models 3511, 3551, 3611, and 3616 Data Service Units (DSUs)

•Models 3811 and 3911 dial/lease modems

Features

The carrier provides a convenient assembly in which you can install a combination of up to 16 T1 CSUs, T1 DSU/CSUs, DSUs, and/or dial/lease modems in a space-efficient package for crowded computer/ communications room environments.

In addition to the 16 devices, a single carrier operates with a power transformer unit, an optional fan module, an optional Shared Diagnostic Control Panel (SDCP), and an optional speaker panel (for use with Models 3811 and 3911 dial/lease modems only).

The number of devices that can be installed in a carrier is reduced by one for each Time Division Multiplexer (TDM) or Multichannel Multipoint (MCMP) circuit card that is installed. A TDM or MCMP card (functioning as a multiplexer or digital bridge) is physically attached to a Model 3611 DSU and occupies a separate slot in the carrier. For digital bridge applications, each DBM-V, DBM-S, or DBM-D occupies a separate slot, as well.

The ac power distribution systems for the carrier consist of a power transformer unit that contains two transformers, each serving eight slots in the carrier. The backplane distributes low-voltage ac power from the transformers to each slot, and an individual power supply on each DSU or dial/lease modem produces the regulated dc voltage.

A carrier designed to operate from a ± 48 Vdc power unit is also available. This unit, called the Central Office (CO) Power Unit, consists of a single dc power module with a fan and operates in Basic mode (the mode of operation in which the single power module supplies power to the entire carrier). An optional second power module is available for the CO Power Unit. With the optional second power module, the CO Power Unit can be configured to operate in either the Redundant mode (the mode of operation in which both power modules serve all the slots in the carrier and if one power module fails, the remaining power module assumes the entire load) or the Independent mode (the mode of operation in which each power module serves only eight consecutive slots ±

Slots 1 through 8 or Slots 9 through 16 in the carrier). The Shared Diagnostic Unit (SDU), which is contained in Slot 0, is powered by both power modules. For more information, see the COMSPHERE ± 48 Vdc Central Office Power Unit Installation Guide.

COMSPHERE 3000 Series Carrier

Figure 1-1. COMSPHERE 3000 Series Carrier

An optional fan module for the ac carriers is available to provide forced air cooling to dissipate heat generated within the carrier. It is recommended that fully configured carriers and cabinets be installed with fan modules to extend the life of the equipment. Guidelines for fan module provisions are listed in Table 3-1 of the Fan Module Installation section in Chapter 3.

An SDCP is required for initial installation and for testing of 3600 Series DSUs, 3151 T1 CSUs, and 3161 T1 DSU/CSUs and their options. Models 3811 and 3911 dial/lease modems can be installed using the SDCP or AT commands from the attached DTE. The SDCP, in conjunction with the SDU, allows up to eight COMSPHERE 3000 Series Carriers to be managed from one control panel. Models 3551, 3611, and 3616 DSUs and Models 3811 and 3911 dial/lease modems are managed by either the COMSPHERE 6700 or 6800 Series Network Management System (NMS).

Within the carrier, the first slot (Slot 0) is reserved for the SDU. The SDU provides the required interface that daisy chains carriers together for NMS and/or SDCP control. In a cabinet configuration, connectivity between the DSUs in the individual carriers allows control of compatible units in the cabinet through a single NMS interface, a single SDCP, or both.

On the rear of the carrier is a pair of 50-pin connectors (P21 and P22) that provide the following network interfaces:

•Digital line interface for DSUs.

•Analog leased-line interface for dial/lease modems.

Introduction

Network Interface Modules (NIMs) can be installed at the rear of the carrier (when not occupied by an Auxiliary Backplane) to provide the PSTN (dial) or switched

56 kbps digital service interface for both DSUs and dial/lease modems. There are nine different NIMs. For a list of the feature/part numbers of these NIMs, see Appendix B of this manual.

Alternatively, you can install up to two Auxiliary Backplanes at the rear of the carrier to allow Model 3151 T1 CSUs and Model 3161 T1 DSU/CSUs to provide an interface between a T1 digital network and Customer Premise Equipment (CPE).

A modular DSU or dial/lease modem is a circuit card that contains ªgold fingerº contacts on the rear edge of the card and is supplied with a rear connector plate. A rear connector plate has two DTE connectors, a 25-pin EIA-232 connector and a 25-pin CCITT V.35 connector. It allows removal of a modular circuit card without disconnecting the DTE cables at the rear of the carrier. Also, there are connector modules which have six ports and are supplied with the modular DSU-TDM or

DSU-MCMP circuit cards. These connector plates and modules function as interfaces between the modular circuit cards and the DTEs.

This manual describes the procedure for installing a COMSPHERE 3000 Series Carrier into a COMSPHERE 72-inch cabinet. A COMSPHERE 72-inch cabinet with available equipment-mounting dimensions of 63 inches high by 19 inches wide has the capacity to hold up to six carriers, allowing for a high-density installation combination of up to 96 DSUs and/or dial/lease modems. COMSPHERE 3000 Series Carriers can also be mounted in other types of EIA standard 19or 23-inch wide cabinets. (The heights of the other types of cabinets may vary.)

Installation Planning

One COMSPHERE 72-inch cabinet can accommodate up to six COMSPHERE 3000 Series Carriers. A cabinet does not need to be fully populated with carriers, however. There are several general rules to follow during installation of the carrier.

1.If installing multiple carriers, install the lower one first, and if installing a full cabinet of carriers, install the carriers from the bottom of the cabinet and work up. This provides the following:

a.Proper alignment for subsequent carriers.

b.Easier carrier installation since they can be placed in the mounting and lowered onto the mounting screws.

c.Easier connection of the DTE interface.

d.Proper cabinet balance. Bottom-up installation keeps the cabinet from becoming top heavy.

2.You must mount carriers when they are empty.

If a carrier is installed in an EIA standard 23-inch (wide) cabinet, however, the mounting brackets on the carrier must be reversed before the carrier is mounted. Carriers can be installed in either EIA standard 19or 23-inch (wide) cabinets.

Models 3551, 3611, and 3616 DSUs and Models 3811 and 3911 dial/ lease modems within the COMSPHERE 3000 Series Carrier(s) can be managed from an SDCP, a Network Management System (NMS), or both. Remember that the Models 3551, 3611, and 3616 DSUs and Models 3811 and 3911 dial/lease modems are managed by the 6700 or 6800 Series NMS. A COMSPHERE 3000 Series Carrier cannot be connected to both a 6700 Series NMS and a 6800 Series NMS at the same time.

The location of the SDCP within the cabinet should be determined ahead of time. It should be installed at a convenient level, usually at eye-level. In a fully configured cabinet, this would be the fourth or fifth carrier from the bottom. Note that the Model 3511 DSUs are not capable of being managed by an SDCP.

The alarm output connection is closed, activating the customer-supplied alarm, when any DSU or Model 3811 or 3911 dial/lease modem in the carrier has an alarm condition that lights the red Alrm LED of the DSU or modem. For information on how to connect the alarm output, see the Alarm Output Connection section in Chapter 3.

Up to eight carriers can be controlled by an SDCP, but there must be a Shared Diagnostic Unit (SDU) installed in each carrier. (Slot 0 in each carrier is reserved for the SDU.) The SDU provides the interface that connects the SDCP to other carriers. Cabling is required that daisy chains these interfaces together.

If the units in the carriers are to be managed from an NMS, an SDU is required in all carriers. Up to eight carriers can be daisy chained together.

Cooling requirements should be given consideration. Depending upon the number of units in the carrier and how they are equipped, a fan module may be recommended. Table 3-1 in Chapter 3 will help you determine whether or not you need additional cooling for your carrier.

Two 50-pin connectors (P21 and P22) at the rear of the carrier, each serving eight slots, provide the digital interface for DSUs and the analog leased-line interface for dial/lease modems. DSUs and dial/lease modems can be placed in the same carrier, but they should be grouped together, (e.g., eight DSUs with a digital interface and eight dial/lease modems with an analog leased-line interface).

COMSPHERE 3000 Series Carrier

If modular devices are installed in the same carrier as non-modular devices, the modular devices must be installed to the left of all other devices, as viewed from the front of the carrier.

If your carriers are equipped with DSUs with DBMs, dial/lease modems, or modems having dial backup capability, the half of the carrier containing those devices must have a Network Interface Module (NIM) installed to provide a dial network or switched 56 kbps digital service interface. Since one module serves eight slots, it is best to group units with dial capability.

NIMs can be installed at the rear of the carrier. There is a total of nine different NIMs available.

The carrier's backplane contains connectors which automatically engage mating connectors on DSUs (and TDM or MCMP circuit cards, if installed) or dial/lease modems when they are installed. To prevent accidental contact with these connectors, use filler panels for unfilled slots. Verify that you have ordered a sufficient quantity.

To use 3151 CSUs or 3161 DSU/CSUs in the carrier, you must remove any rear connector plates or modules and add the 3151/3161 Auxiliary Backplane. Using a single Auxiliary Backplane, you can install any combination of up to eight 3151 CSUs and 3161 DSU/CSUs on one side of the 3000 Series Carrier, and up to eight 3600, 3800, and 3900 Series devices on the other side of the carrier. Alternatively, using two Auxiliary Backplanes, you can install up to sixteen 3151 CSUs or 3161 DSU/CSUs in a single 3000 Series Carrier.

For each non-modular TDM or MCMP circuit card installed in the carrier, determine whether the circuit card is to be used as a Time Division Multiplexer (TDM) or as a digital bridge. A TDM interface cable is supplied with each non-modular TDM or MCMP circuit card. However, a digital bridge interface cable must be ordered separately.

For modular TDM or MCMP circuit cards, use standard cables for Ports 1 through 6. However, a 6-port V.35 interconnect cable is required for the 26-pin high-density D-type connector on the connector module. This cable must be ordered separately.

It is recommended that you do not perform any procedure that removes power to the carrier (for example, replacing the power transformer unit or disconnecting power to the power transformer to install an SDCP in a fully configured carrier) during peak operating hours since disconnecting power disables all units in the carrier.

COMSPHERE 3000 Series Carrier

Overview

A COMSPHERE 72-inch cabinet is available for mounting the COMSPHERE 3000 Series Carriers. Up to six carriers can be mounted into a single cabinet. The COMSPHERE 3000 Series Carriers can also be mounted into other commercial EIA standard 19-inch and 23-inch cabinets.

The COMSPHERE 3000 Series Carrier, Figure 3-1, is designed to house T1 CSUs, T1 DSU/CSUs, DSUs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs, MCMPs, and dial/lease modems. The carrier is a metal enclosure that contains slots for installation of 17 circuit cards. The slot labeled SDU (Slot 0) is reserved for the Shared Diagnostic Unit (SDU); Slots 1 through 16 are for T1 CSUs, T1 DSU/CSUs, DSUs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs,

MCMPs, or dial/lease modems. Under each slot number (on the cover plate or SDCP) is a small area in which to write the circuit channel identification numbers.

The carrier's backplane contains connectors which automatically engage mating connectors on the devices as they are being installed. Filler panels (which must be ordered separately) are required for unfilled slots.

Two 50-pin connectors (P21 and P22) at the rear of the carrier (each serving eight carrier slots) provide an interface between the carrier and the digital line for DSUs and the carrier and the leased line for dial/lease modems. Above these are connectors for the dial network connections (P23 and P26). One or two network interface modules (each serving eight carrier slots) can be ordered, as needed, to establish dial network connections.

Installation

There are nine NIMs available. The following NIMs are used with the 3600 Series DSUs/DBMs:

•Permissive NIM (for use with V.32 and 2-wire Switched 56 DBMs)

•Programmable NIM (for use with V.32 DBMs)

•4-wire Switched 56 NIM (for use with 4-wire Switched 56 DBMs)

WARNING

Do not connect a 2-wire switched 56 kbps plug into an RJ11C jack. This type of jack is intended for analog PSTN devices. Failure to do this may cause equipment damage and harm to the telephone network.

The following NIMs are used with the dial/lease modems, or a combination of DSUs with V.32 DBMs and dial/lease modems in the same carrier half:

•Permissive NIM (3911 only)

•Permissive NIM with the Make Busy feature

•Programmable NIM with the Make Busy feature (3811 only)

•Permissive NIM with the Service Line feature

•Programmable NIM with the Service Line feature (3811 only)

•Permissive NIM with both the Make Busy and Service Line features

•Programmable NIM with both the Make Busy and Service Line features (3811 only)

NOTE

You cannot use a NIM on the side of the carrier where an Auxiliary Backplane is installed.

Programmable mode corrects any loss in the transmit signal level between the modem and the central office by permitting the modem to transmit at the optimum signal level. This is accomplished by the local telephone company installing a resistor into the network interface and is usually identified by an RJ45S-type jack.

Permissive mode is a standard dial-line connection and is identified by the use of an RJ11Cor SJA48-type jack. (The carrier also supports RJ21Xand RJ27X-type mass termination interfaces for Permissive and Programmable modes, respectively.)

The DDD NIMs, programmable and permissive, may have Make Busy and Service Line as additional capabilities. The Make Busy feature is useful when modems are used in a ``huntº or ``rotaryº group. This feature ties the Tip and Ring signals together so that the modem appears busy. Make Busy is not used by DSUs with DBMs, but using a NIM with this feature will not affect the DBM's performance. The Service Line feature permits an extra dial line to be connected to a COMSPHERE 3000 Series Carrier. NIMs with this feature are identified by the two modular connectors mounted on the NIM.

WARNING

The Make Busy feature must only be used behind a PBX. Connecting a NIM with the Make Busy capability directly to the PSTN is a violation of FCC

Part 68 Rules and Canadian DOC CS-03 Regulations.

Non-modular DSUs equipped with TDM or MCMP circuit cards are supplied with time division multiplexer interface cables. If you plan to use the digital bridge function, you must order a digital bridge interface cable.

When modular DSUs or modems are to be installed in the carrier, rear connector plates or connector modules must be installed at the rear of the carrier. Modular DSUs and dial/lease modems are circuit cards that can be removed from the front of the carrier without disturbing the DTE cables attached to the rear connector plate at the rear of the carrier. Also, there are connector modules that are supplied with the modular DSU-TDM (or DSU-MCMP) circuit cards. These connector plates and modules function as interfaces between the modular circuit cards and the DTEs.

A power transformer unit provides low voltage

ac power to the carrier's internal power distribution bus. A carrier designed to operate from a ± 48 Vdc power unit is also available. This power unit is called the Central Office (CO) Power Unit and it consists of one dc power module. Note that an optional second power module is available. For more information on the CO Power Unit, see the COMSPHERE ± 48 Vdc Central Office Power Unit, Installation Guide.
