Runs internally throughout each PN and terminates on each end. It is an 18-bit parallel b us th at ca rries l og ical lin ks a nd co ntro l mes sages from the SPE, through port circuits, to endpoints such as terminals and adjuncts.

The packet bus carries logical links for both on-switch and off-switch control between some specific port circuits in the system; for example, D-channels, X.25, and remote management terminals. Typically, the csi model does not support the packet bus. Any MAPD or ISDN application rides the TDM bus. However, in R7 and later csi systems wi th C- LAN, the applications use the pa ck et bu s prov id ed by the C-LAN board.

■

Port circuits

: form analog/digita l interface s between t he PN and ext ernal trunk s and devices providing links between these devices and the TDM bus and packet bus. Incoming analog signals are converted to pulse-code modulated (PCM) digital signals and placed on the TDM bus by port circuits. Port circuits convert outgoing signals from PCM to an al og for ex tern al an alog devices. All port ci rcu its c on nect to the TDM bus. Only specific ports connect to the packet bus.

The system consists of 2 main components:

■ The Oryx/Pecos rea l-time, m ultiproce ssing o perating s ystem. Oryx/Pecos supports

the SPE.

■ Applications layer, consisting of 3 major subsystems:

— Call processing: starts up and compl etes call s and mana ges voic e and data in

the system.

— Maintenance: detects faults, recovers operations, and performs tests in the

system.

— System management: controls the internal processes necessary to install,

administer, and maintain the system.

Logical interconnection between system components refers to the 2 kinds of logical links into the SPE:

■ System links for internal system control

■ Application links used by external applications such as adjuncts

Duplication

IP SoftPhones

IP SoftPhones extend the level of DEFINITY services. They turn a PC or a laptop into an advanced telephon e. You can place calls, t ake call s and han dle multi ple call s on your PC. There are 4 types of telephones available. They are:

Telecommuter application -- a multifunction station that runs on a PC plus a conventional telephone. Call control is done on the SoftPhone and the voice path is on the DCP se t. T his IP SoftPh one is i nten de d to be used by home workers w ho require PSTN quality audio. The MedPro board is not used in this application.

Road-warrior applicati on -- a multi function stati on that is based e ntirely on t he PC. It is used when there is only a single telephone line available to access the IP network and the DEFINITY. This IP SoftPhone is intended to use by your traveling associates. The MedPro board is used for the road-warrior application.

CentreVu IP Agent -- This SoftPh one is the t elecomm uter appli cation th at has b een configured to use the CentreVu IP Agent user interface software. It is used as a Call Center agent station.

Native H.323 -- This is an IP-connected SoftPho ne running off-the-shelf H.323 software. It operates as a single-line phone with limited features, which are activated by Feature Access Codes.

Duplication

Duplication is a strategy to create fully redundant systems. Duplication minimizes single failure points that can interrupt call processing. Three system duplication options are available:

■ Standard reliability--this is the only reliability configuration option available for

DEFINITY ECS csi model. Will not duplicate Tone-Clock(s), the Control Carrier or any inter-PN co nnectivity.

■ High reliability--duplicates the hardware that is associated with the SPE. The

Control Carrier is duplicated, which provides duplicate SPEs and Tone-Clocks. Inter-PN connectivity and EPN Tone-Clocks are not duplicated. The strategy is to duplicate items th at are associ ated with the SPE so that a s ingle fau lt will not ca use the loss of the SPE. High reliability is available with DEFINITY si and r models.

Administration

■ Critical reliability--is available with DEFINITY si and r models and requires the full

duplication of the SPE, inter-PN connectivity and the Tone-Clocks (Category A only).

■ ATM Network Duplication--requires full duplication of the inter-PN connectivity and

Connecting with TCP/IP Networks

LAN Gateway

With the optional J58890MA-1List 2 LAN Gateway circuit-pack assembly installed, DEFINITY ECS works with PC/LAN-based communications applications that support the CallVisor Adjunct-Switch Application Interface (ASAI) (Category A only).

C-LAN

TCP/IP Connectivity is provided over Ethernet or Point-to-Point Protocol (PPP) to adjuncts such as CMS Call Center and INTUITY AUDIX and for DCS connectivity. The C-LAN circuit pack (TN799) provides a "bridge" from the TDM bus to the packet bus on DEFINITY ECS csi.

Network Control/Packet Interface

Communicates control channel messages between the processor circuit pack and the distributed network of port circui t packs on the TDM bu s. The NetPkt ci rcuit pack (TN7 94) provides 8 asynchronous data channels that process and route information directly from the processor circuit pack to customer-connected equipment.

PassageWay Integrated Voice/Data-Workstation Applications

PassageWay applications make the features of the DEFINITY ECS telephone system available from the Window s d esktop. With Pa ssag eW ay and the D EFIN ITY LAN gate way implemented, a Call Center application could, for instance, let Agents access all

job-related resources—the order-processing database, company World Wide Web site, phone system, voicemail system, and fax machine—from a single interface on the PC.

Connecting with ATM Port Networks (Category A only)

ATM-PNC (Category A only)

ATM Port Network Connectivity (ATM-PNC) provides an alternative to either the direct connect or Center Stage Switch configurations for connecting the Processor Port Network (PPN) to one or m ore Ex pan si on Port Netw o rks (EPNs ). ATM-PNC replaces the Center Stage Switch in a DEFINITY R8r network with an Asynchronous Transfer Mode (ATM) switch. ATM-PNC is available with all three DEFINITY ECS reliability options— standard, high, and critical.

ATM-PNC integrates delivery of voice, video, and data via ATM over a common large bandwidth LAN, providing reduced infrastructure cost and improved network manageability. ATM-PNC uses standards-based open interfaces that can be provisioned with either new or existing DEFINITY ECS systems and is ATM-ready for future expansion.

ATM-CES (Category A only)

ATM-CES (Circuit-Emulation Service) lets the DEFINITY ECS emulate an ISDN-PRI trunk on an ATM facility. These virtual trunks can serve as integrated access, tandem, or tie trunks. ATM-CES trunk emulation maximizes port n etwork capacities by conso li dati ng trunking. For example, the CES interface can define up to ten virtual circuits for tie-line connectivity, consolidating onto one circuit card netwo rk conne ctivity tha t usually requ ires multiple circuit packs.

ATM WAN (Category A only)

ATM Wide Area Network (ATM WAN) extends the Port Network Connectivity (PNC) beyond a single ATM switch. This allows you to use either a private ATM network, public WAN, or a combination of both. Several networked ATM devices can be used as effectively as a single ATM switch for inter-port network connectivity. ATM WAN is supported by the "Multiple Location" feature, where port network cabinets can be administered as se parate loca tions; how ever , it is not required . You can use multiple A TM switches without multiple locations administered.

Overview of DEFINITY ECS R8

IP Solutions (Category A only)

As shown in Figure 1, D EFINITY ECS IP Solutions supports IP c onnec tiv it y fo r two types of trunks and three types of IP Softphones.

DEFINITY ECS IP Solutions is implemented using the TN802/TN802B IP Interface assembly, which is a Windows NT server that resides on the IP-Interface circuit pack inside the DEFINITY ECS. The TN802B IP Interface, introduc ed in R elease 8, operates in either the IP Trunk mode (for IP trunk connections) or in the MedPro mode (for H.323 trunk connections and H.323 voice processing for IP softphones). The TN802 IP-Interface, introduced in Release 7, operates only in the IP Trunk mode. The TN802B defaults to IP Trunk mode and is backward compatible with Release 7. The MedPro mode requires the new TN799B C-LAN circui t pack.

With Release 7 software, or with Release 8 software configured as Release 7 (that is, R8 used as a bugfix for R7), the TN802B can be used only in the IP Trunk mode. With Release 8 software, the TN802B can be used in either mode but each TN802B can operate in just one of the two modes at a time; that is, all trunks supported by the same TN802B must all be operating in the same mode. DEFINITY ECS supports multiple TN802Bs operating in a mixtu re of the tw o modes or a combi nation of TN802 s (opera ting in the IP Trunk mode) and TN802Bs (operating in either mode).

The IP Trunk and MedPro modes are not interoperable; that is, the TN802B in MedPro mode cannot communicate with another TN802B in IP Trunk mode or with a TN802.

Trunks

DEFINITY ECS IP Solutions supports two trunk configurations:

■ H.323 Trunk

■ IP Trunk

H.323 Trunk

MedPro mode supports the H.323 version 2 protocol and interoperates with H.323 version 2 endpoin ts, incl uding s tations, trunks, a nd gatewa ys. The TN80 2B IP In terface in Medpro mode enables H.323 trunk service using IP connectivity between two DEFINITY ECS systems. H.323 trunk groups can be configured as DEFINITY-specific tie trunks supporting ISDN trunk features such as DCS+ and QSIG, or as generic tie trunks

permitting interconnection with other vendors’ H.323 v2-compliant switches, or as direct-inward-dial (DID) type of “public” trunks providing access to the switch for unregistered users. TheTN802B in MedPro mode requires the TN799B for signaling.

IP Solutions (Category A only)

IP Trunk

In Release 8, the IP Trunk mode will typically be chosen for interoperability with existing TN802 (as opposed to the TN802B) IP Interface circuit packs.

The IP Trunk m ode allows trunk groups to be defin ed as DS1 t ie lines b etween DEFI NITY ECS systems over a virtual private network (VPN). Each IP Interface circuit pack in IP Trunk mode provides a basic twelve-port package that can be expanded up to a total of 30 ports.

The benefits of IP Trunk include a reduction in long distance voice and fax expenses, facilitating global communications, providing a full-function network with data and voice convergence and optimizing networks by using the available network resources.

Each TN802 or TN802B in IP Trunk mode requires a connection to a modem and an incoming line for Lucent remote access. The TN802 (but not the TN802B in IP Trunk mode) also requires direct access to the NT server on the TN802 hard disk using pcANYWHERE, version 8 or later. A TN802B in the IP Trunk mode does not require the TN799B.

IP Softphones

DEFINITY IP Softphones operate on a PC equipped with Microsoft Windows 95/98/NT and with TCP/IP connectivity to DEFINITY ECS.

DEFINITY IP Solutions supports three IP Softphone configurations:

■ Road-warrior application (voice over IP)

■ Telecommuter application (dual-connection)

■ CentreVu IP Agent (dual-connection)

■ Native H.323

Road-warrior applicatio n

The road-warrior application of the DEFINITY IP Softphone enables travellers to use the full DEFINITY ECS feature set from temporary remote locations anywhere in the world such as a hotel room. The road-warrior application consists of two software applications running on a PC that is connected to DEFINITY ECS over an IP network. The single network connection between the PC and DEFINITY ECS carries two channels, one for the signaling path and one for the voice path. DEFINITY IP Softphone software handles the call signaling and an H.323 V2-compliant audio application, such as Microsoft NetMeeting, handles the voice communications. The user places and receives calls via the IP Softphone interface on the PC and uses a headset connected to the PC (or the

PC’s microphone and speakers) to speak and listen. With the road-warrior application, NetMeeting has been configured to run in the

background and use only the audio portion of the applications. The data collaboration feature of NetMeeting can be used as a stand-alone application but it is disabled during an IP Softphone session.

On DEFINITY ECS, the roa d-warrior app lication of th e IP Softpho ne requires the TN799B (C-LAN) for signaling and the TN802B IP Interface circuit pack assembly running in MedPro mode for voice processing. Each VOIP Softphone requires the administration of two stations — an H.323 station and one of the types of DCP station.

Telecommuter application

The telecommuter application of the DEFINITY IP Softphone enables telecommuters to use the full DEFINITY ECS feature set from home. It consists of a PC and a telephone with separate connections to DEFINITY ECS. The PC is connected to DEFINITY ECS over an IP network to provide the signaling path. The PC runs the DEFINITY IP Softphone software to provide the user interface for call control. A standard telephone is connected to DEFINITY ECS over the public switched telephone network (PSTN) to provide a high-quality voice path. The user places and receives calls via the IP Softphone interface on the PC and uses the telephone handset to speak and listen.

On DEFINITY ECS, the telecommuter application of the IP Softphone requires the TN799B (C-LAN) for signaling. The TN802B IP Interface is not used for the telecommuter application. Each instance of the telecommuter application requires the administration of two stations — an IP Softphone station and one of the types of DCP station.

DEFINITY ECS floor plans vary with the size and shape of the equipment room and the extent of future growth. Future growth includes a new or upgraded system, adjuncts and peripherals, and the cross-connect field. See ‘‘Cross-Connect Field’’ on page 41.

For floor standing cabinets, reserve the area behind a cabinet for the cross-connect field and the cable slack manager. For wall mounted cabinets, reserve the area beside the cabinets for the cross-c onnec t field. F igure 10 through Figure 15 show ty pical floo r plans . All dimensions are shown in inches. Refer to Table 11 for power requirements.

Compact Modular Cabinet (CMC) Configuration Guidelines

The cross-connect field is either to the rear or right of the cabinet. To allow service access, the table for the management terminal and optional printer is away from the equipment area. See Figure 10 and ‘‘Table Area’’ on page 40 for requirements. In an installation where no cross-connect field is present, an cross-connect field can be installed in the CMC right panel.

The following steps are pre-installation guidelines:

1. Locate the powe r outlet s outs ide th e cros s-con nect fi eld area. The ou tlets m ust n ot be controlled by a wall switch or be shared with other equipment.

2. Locate the trunk/auxiliary field inside the cross-connect field, if desired.

3. Ground the system. See ‘‘Approved Grounds’’ on page 62.

4. Each cabinet requires either: NEMA 5-15R receptacle (or equivalent) for United States installations or local IEC 320 cord set (or equivalent) for non-United States installations.

Environmental Considerations

Air Purity

The Compact Modular Cabinet, Single-Carrier and Multi-Carrier Cabinets contain an air filter to reduce particulates flowing through the equipment. Do not install the cabinet where the air may be contaminated by excessive dust, lint, carbon particles, paper fiber contaminants, or metallic contaminants. For example, do not install the cabinet near paper handling equipment such as copiers and high-speed printers, which introduce paper dust and print particles into the environment. Corrosive gases above the levels in

Table 7 must be avoided.

) to meet the

Radio Frequency Noise

Noise is introduced into the system through trunk or station cables, or both. Electromagnetic fields near the system control equipment may cause system noise. Place the system and cable runs in areas where high electromagnetic field strengths do not exist. Radio transmitters (AM or FM), television stations, induction heaters, motors with commutators of 0.25 horsepower (187 watts) or greater, and similar equipment are leading causes of interference.

DEFINITY Enterprise Communications Server Release 8.2 System Description

Site Requirements

555-233-200

April 2000

Environmental Considerations

Small tools with universal motors are generally not a problem when they operate on separate power lines. Motors without commutators generally do not cause interference. Field strengths below 1.0 volt per meter are unlikely to cause interference.

Measure weak fields with a tunable meter. Measure field strengths greater than 1.0 volt per meter with a broadband meter.

Estimate field strengths of radio transmitters by dividing the square root of the emitted power in kilowatts by the distance from the antenna in kilometers. This yields the approximate field strength in volts per meter and is relatively accurate for distances greater than about half a wavelength (150 meters for a frequency of 1000 kHz).

Acoustic Noise Generated by Cabinets

Acoustic noise levels are provided below. In all types of cabinet configurations, if the system cabinet door is open, there is an additional 1 dBA (decibels measured acoustically) of noise. Table 8 lists some typical noise figures for various cabinet combinations.

The battery charger is used only without an Uninterruptible Power Supply (UPS). The charger contains:

■ Three 48-VDC batteries for backup power to the cabinet

■ A DC-power relay to switch the batteries into the power circuit if a main power

failure is detected

Circuit Breaker

The circuit break er prote cts th e AC inp ut power to the cab inet and serves as th e main AC input disconnect switch. The circuit breaker has 2 poles for 120 VAC or 3 poles for 208/240 VAC. If a problem develops, the circuit breaker automatically trips (opens) and removes the AC power input.

48-VDC Batteries

The 3 series-connected 48-VDC batteries produce a nominal 144 VDC, fused at 20 A. The batteries trickle-charge from the battery charger.

Battery Charger

When AC power restores after an outage, the battery charger converts a 120 VAC input to a DC voltage that recharges the batteries (usually within 24 hours).

DC Power Relay

This relay disconnects the batteries from a system when using AC power. The relay also disconnects the batteries if power fails for more than 10 minutes in a standard reliability system, 5 minutes in high and critical reli abi lity systems, and 10 mi nu tes in an exp ans ion port network (EPN). This protects the batteries from over-discharging.

Electromagnetic Interference (EMI) Filters

The EMI filters suppress noise voltage on the AC input line to the unit.

Ring Generator

The ring generator converts the -48 VDC input to a 67 VAC to 100 VAC, 20 Hz or 25 Hz ringing voltage. The analog line circuit packs use this AC voltage output to ring voice terminals. The AC outputs route from the ring generator to port carriers, expansion control carriers, and control carriers.

Fuses

20-Amp fuses protect the power on each cable going from the AC- Power Distribution Unit to power converters in the carriers.

Power Backup

If AC power fails, three 48-VDC batteries power the system for 10 seconds in a PPN cabinet, for 15 seconds in an EPN cabinet, and for 10 minutes in the control carrier in a standard reliability system. The batteries also supply system power for 5 minutes in the control carrier in high and critical reliability systems, and for 10 minutes in the expansion control carrier in the A

position of an EPN cabinet (R7r and later only).

Uninterruptible Power Supply (UPS)

An external, Uninterruptible Power Supply (UPS) provides a longer backup time than holdover batteries (holdover times vary from less than 10 minutes to up to 8 hours) and can replace the batteries and battery charger. The unit connects from the AC-power

source to a cabinet’s AC-power cord. If AC power fails, the unit supplies its own AC power to the cabinet.

Power Backup

There are 2 types of battery assemblies used for power backup: small and large. The small batteries are t ypicall y locate d at the c enter rear of a Mult i-Carrier Cabin et. The la rge batteries are typically located inside the battery cabinet.

Small Batteries

The small battery is an 8 AH (Amp-hour) battery fused for short circuit protection and is charged by the J58890CH-1. The batteries also contain a thermal sensor that changes the charging voltage depending on battery temperature. See Figure 25.

The small batteries provide short-term battery holdover. If AC power fails, 48 VDC batteries power the system for 10 seconds in a PPN cabinet, for 15 seconds in an EPN cabinet, and for 10 minutes in the control carrier in a standard reliability system. The batteries also prov ide sy stem powe r for 5 mi nutes in the c ontrol carrier in h igh an d criti cal reliability systems , and for 10 m in utes in th e ex pa nsi on con trol carri er in the A po si tion of an EPN cabinet (R7r and later only).

Single-Carrier Cabinet Power Systems

Each Single-Carrier Cabinet has 1 AC or 1 DC power supply that distributes DC-power and AC ringing voltage to the circuit pack slots in the cabinet.

AC Power Supply (1217A)

In an AC-powered cabinet, a single, plug-i n, multi-out put AC power supp ly is in the power supply slot. A power cor d, with a 3-pr ong pl ug on one en d and an app lianc e conn ector on the other end, connects the supply to a dedicated AC power source.

The 1217A is a global power unit for Single-Carrier Cabinets. It has a wide input voltage operating range of 90 to 264 VAC and a 50/60 Hz autoranging input, multi-output power supply that provides regu late d D C output. The 1217A also has a s el ect abl e 20 /25 Hz AC ringer .

The inputs to the power supply can be (depending on list version):

■ 120 VAC, 60-Hz, 15-Amp to 20-Amp; 3 wires in the power cord: 1 hot wire, 1

neutral wire, and 1 ground wire

■ 220 VAC or 240 VAC, 50-Hz, 10-Amp; 3 wires in the power cord: 1 hot wire, 1

neutral wire, and 1 ground wire

The AC power supply produces the following DC outputs: +5 VDC, –5 VDC, –48 VDC,

+12 VDC, and a b attery- charging voltage. The DC o utputs di stribute power on the cab inet backplane t o the circuit pack slots. Additionally, the -48 VDC output current capacity has been increased from 6.85 amps to 8.25 amps. A 50 amp load inrush requirement has been added to the -48 VDC output

A holdover circuit in the power supply allows a system to operate normally during AC power interruptions. If AC in put power fails, re serve ba tteries sup ply power to the m emory and processor circuit packs and fans for 2 minutes. All port circuit packs are inactive during this time. The power supply contains a battery charger to charge the holdover batteries.

Cabinet Cooling Fans

Compact Modular Cabinet (CMC) Fan Unit

Two variable-speed fans are at the bottom of the cabinet. They receive +8 to +14 VDC from the power supply. An air filter, which can be removed and cleaned or replaced, is located above the fans. Air flows from the outside, into the bottom of the cabinet, around the circuit packs, and out through the top of the cabinet.

If the cabinet temperature reaches 158 supply shuts the system down and invokes the emergency transfer.

Multi-Carrier Cabinet Fans

A fan unit consisting of 6 fans, mounts near the center of the cabinet. The 3 front fans blow up and the 3 rear fans blow down. A removable air filter is provided above and below each fan unit. Four sensors monitor the cabinet temperature; 3 sensors are inside the cabinet top and 1 sensor is inside the cabinet bottom. One of the top sensors affects the speed of the front fans and the bottom sensor affects the speed of the rear fans. A speed control and thermal ala rm circu it in each fan monitors the sen sor s. When a sensor

indicates a change in cabinet temperature, the circuit in a fan changes that fan’s speed accordingly.

A power cable from th e Pow er Dis tributi on Uni t con nects -4 8 VD C to e ach f an, +5 VDC to the speed control and thermal alarm circuit in each fan, and temperature sensor signals to the equivalent circuit in each fan. One pair of wires routes to each fan circuit. Alarm signals also route to the equivalent circuit in each fan. One pair of wires routes to each fan circuit.

A minor alarm is sent to the processor circuit pack in the PPN cabinet and the maintenance circuit pack in an EPN cabinet if any fan’s speed drops below minimum. A minor alarm occurs if a fan has stopped due to loss of -48 VDC. A major alarm is sent by one of the cabinet top therm al sensor s if the exha ust temper ature reache s 149

System Protection

Protections are established to keep the DEFINITY System active and on line. The following 4 types of system prot ect ion are provi ded :

■ Overvoltage

■ Sneak current

■ Lightning

■ Earthquake

Overvoltage Protection

Protection from hazardous voltages and currents is required for all off-premises (out-of-building) trunks, lines, and terminal installations. Both over-voltage protection (lightning, power induction, and so forth) and sneak current protection are required. The following devices protect the system from overvoltages:

■ Analog trunks use the 507B Sneak Protector. Over-voltage protection is normally

provided by the local telephone company.

■ Analog voice and 2-wire DCP terminals can use 1 of the following (or equivalent)

types of combined overvoltage and sneak current protection:

— Carbon block with heat coil for UL code 4B1C — Gas tube with heat coil for UL code 4B1E-W — Solid state with heat coil for UL code 4C1S

■ DCP and ISDN-BRI terminals use the solid state 4C3S-75 with heat coil protector,

or equivalent.

■ DS1/E1/T1 circuits require isolation from exposed facilities. A CSU (T1), LIU (E1),

or other equipment provides this isolation.

System Protection

Sneak Current Protection

Sneak current protection uses fuses to protect building wiring between the network interface and trunk circuits when exposed to extraneous power. The fuses also protect the circuit packs.

All incoming and outgoing trunks and off-premises station lines pass through the sneak fuses. 507B Sneak fuse panels install on the system side of the network interface.

Sneak current protectors must be either UL listed/CSA certified or must comply with local safety standards. Sn eak current pro tectors m ust have a maximu m rating of 350 mA and a minimum voltage rating of 600V, or as required by local regulations.

Lightning Protection

A Coupled Bonding Conductor (CBC) in the cabinet ground wiring protects the system from lightning. The CBC runs adjacent to wires in a cable and causes mutual coupling between itself and the wires. The mutual coupling reduces the voltage difference between ground and the DEFINITY ECS.

When using a CBC, be sure that it connects to telecommunication cable that is firmly connected to an approved ground. In multipl e-story buildings , be sure to connect th e CBC to an appr oved ground at each floor.

The CBC can be a 10 AWG (5.3 mm surrounding wires within a cable, or 6 unused pairs of wire within a cable, twisted and soldered together. The CBC connects from the cabinet single-point ground bar in an AC-powered cabinet or the gr ound di scharge b ar in a DC-po wered cabine t to the term inal bar at the cross-connect field.

When there is an Auxiliary cabinet, a 6 AWG (13.3 mm system cabinet single-point ground block to the Auxiliary cabinet ground block. The ground wire routes as closely as poss ible to the cables that conne ct the system cab inet to the Auxiliary cabinet.

If equipment is not present in the Auxiliary cabinet, plug the power supply for this equipment into 1 of the 2 convenience outlets on the rear of the Multi-Carrier Cabinet, to preserve ground integrity. The convenience outlet is fused at 5 Amps. A dedicated maintenance terminal plugs into the other convenience outlet.

The above figure is for the configuration of a minimal Dual Expansion Port Network cabinet for the r model. The A, B, and C carriers are intended for the first port network in the cabinet. The D and E c arriers are intende d for the second po rt network in the c abinet. The first carrier of a second Port Network in the cabinet must reside in carrier E. The E carrier must be used when there is only one carrier in the second EPN in the cabinet. When a cabinet has two Port Networks, carrier E must be used and populated first and carrier D added and populated second.

Carrier Circuit-Pack Slots

There are 3 types of circuit pack slots in the carriers: Control, Port, and Service.

NOTE:

The purple-colored and white-colored circuit packs and slots are being replaced by circuit packs and slots labeled with gray and white rectangles, respectively. A label with a solid gray rectangle indicates a port slot/circuit pack. A label with an outlined white rectangle indicates a control slot/circuit pack.

■ Port: colored purple or labeled with a gray rectangle and can accept any purple or

gray-labeled circuit pack

■ Control: colored white or labeled with an outlined white rectangle and can accept

only a circuit pack assigned to that slot

■ Service: colored purple or labeled with a gray rectangle; is a special type of circuit

pack that does not have an I/O connector

Each port slot attach es to a 50 -pin (2 5-pair) conne ctor on the carr ier’s rear pan el. A cable

attaches to each connector and routes to the cross-connect field. Each slot containing a fiber optic interface circuit pack (EI or SNI) uses a fiber optic transceiver on the carrier’s rear panel.

A current limiter board (CFY1B) plugs into the backplane of the control carrier located in

position only. The board supplies emergen cy tran sfer lo gic, c urrent-l imite d power, 5

the VDC to trip the main circuit breaker in an over-temperature condition, and the ringing transfer relay. Terminators on the backplane terminate each end of the processor expansion bus.

The following apparatus blank faceplates (with widths) cover unused circuit pack slots in the carriers to maintain proper air flow:

■ Z100A1 (0.75 inches/1.9 cm)

■ Z100C (0.5 inches/1.27 cm)

■ Z100D (0.25 inches/0.64 cm)

NOTE:

Throughout this section, the power units and circuit packs shown in the front views of the carrie r s a re representative examples o nly. Actual, installed har dw are may vary from that shown.
