1000-A2-GN22-00 1. Voice-over-Broadband Networking

The heart of our VoBB solution is the CPX-1000. IADs, supplied by other manufacturers, reside at subscriber premises. Each IAD provides dial tone to standard (POTS) local telephones and data service, using a single transmission link.

The network architecture provided by the CPX-1000 enables ICPs to extend local dial tone services from an existing Class 5 switch over a packet-based access network. From this perspective, as a loop extender, voice-over-broadband is functionally similar to traditional Digital Loop Carrier (DLC) equipment, where the Class 5 switch provides the actual dial tone, as well as Custom Local Area Signaling Services (CLASS) and calling features.

However, unlike traditional DLCs, which supply the physical subscriber line interface at the central office, the packet architecture places that interface at the subscriber premises.

The benefits of this architecture are:



better voice quality, by performing analog-to-digital conversion near the phone

CPX-1000 Voice Services Platform



more efficient use of copper connections between the subscriber premises and the Class 5 switch

The CPX-1000 supports any broadband access network technology, including voice-over-T1, voice-over-DSL, and voice-over-wireless local loop (Figure 1–1 on page 1-2).

The CPX-1000 is a carrier-class, rack-mounted shelf with redundant components.

The CPX-1000 incorporates a scalable architecture within a single shelf, or by using multiple CPX shelves.



A single shelf can support additional subscribers by adding more network modules or using the spare capacity of existing network modules.



Multi-shelf equipment is comprised of more than one CPX when the capacity of a single shelf is exceeded.

Most shelf components are modules comprised of a line card and a transition card. The line card installs in the front of the CPX and the transition card installs in the rear. A passive midplane within the CPX shelf connects the line modules and transition modules.

Packet Network Configuration

Phone Sys

LAN

Phone Sys

LAN

The CPX-1000 transports voice traffic via an ATM network. When Frame Relay is used, the frames are encapsulated in ATM cells.

In the packet network (Figure 1–3), voice-over-broadband requires a minimum of two Permanent Virtual Circuits (PVCs) across the network for each IAD (in both ATM and Frame Relay networks).



The first PVC transports the voice and management traffic associated with all of the subscriber's telephone lines. The voice PVC is configured as a variable bit rate-real time (VBR-rt) PVC, and has priority over the data PVC.



The second PVC transports the data traffic. The data PVC is typically set up as an unspecified bit rate (UBR) PVC.

Voice is more sensitive to network latency than data, so this configuration ensures that voice traffic always has priority over data. However, this configuration also enables voice traffic to consume bandwidth when a call is in progress. Typically, few subscriber's telephone lines are simultaneously in use, so the majority of the bandwidth is usually available for data service.

For example, over a single 768 kbps symmetric DSL connection, an ICP supports up to eight simultaneous telephone calls using 2:1 compression serving a KTS with 32 extensions at a P.01 grade of service and still delivers data service at an average speed of 550 kbps (Figure 1–4).

However, many network operators have Frame Relay-based local access networks interconnected with ATM networks. The CPX can interface with the Frame Relay network through an Interworking Function (IWF) between the Frame Relay and ATM (Figure 1–3). The IWF is an industry-standard function that either the access mux or a Frame Relay/ATM switch can execute.

In a Frame Relay network, each PVC uses an identifying Data Link Connection Identifier (DLCI). ATM PVCs, however, use a Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI). The IWF maps each Frame Relay DLCI to a corresponding ATM VPI/VCI.

This association between the Frame Relay DLCI and ATM VPI/ VCI is made when provisioning PVCs.

Call Origination and Completion

These steps describe the network interaction that occurs when a subscriber initiates a call (Figure 1–5):

1. A subscriber initiates the call by taking the telephone off-hook.

2. The IAD notifies the CPX through the Common Channel

Signaling (CCS) channel in the voice PVC.

3. The CPX sends an outgoing call request message to the Class 5

switch through the PSTN (GR-303 protocol) Time Management Channel (TMC).

4. The Class 5 switch selects the available time slot in a PSTN

interface group and directs the CPX to connect the IAD port to the specified time-slot on the switch.

5. The host Class 5 switch provides dial tone.

6. The CPX cuts the calling station through to the switch.

7. The subscriber dials the destination number and the Class 5

switch collects DTMF digits.

8. The Class 5 switch routes the call, returns the call progress, and

generates a call data record.

9. The CPX notifies the Class 5 switch when the station hangs up.

These steps describe the network interaction that occurs when a subscriber receives a call (Figure 1–6):

1. The Class 5 switch sends an incoming call request message to

the CPX through the PSTN (GR-303) TMC.

2. The Class 5 switch assigns a time slot.

3. The CPX sends a setup message to the IAD, verifying both

bandwidth and port availability.

4. The CPX connects the specified time slot to an IAD port.

5. The IAD initiates ringing.

6. The IAD notifies the switch via the CPX when the first ring is

complete and connects the station through to the host.

7. The Class 5 switch sends a caller ID to the IAD via the CPX.

8. When the station answers, the CPX sends a call connected

message to the Class 5 switch.

9. The Class 5 switch notifies the CPX when the call is cleared.

10. The CPX notifies the switch when the station hangs up.

A CPX installation is scalable: first by populating an individual shelf, then by adding additional shelves. Each CPX shelf occupies 12 RU (21 inches high) and is 17 inches deep.

Using optional mounting brackets, the shelf can be installed in 19-inch EIA310, Bell Wide, Bell Narrow, and NEBS2000 racks. Reversible mounting brackets allow installation in 23-inch racks.

Equipment Operational Features

A single CPX-1000 can manage than 18,800 subscriber telephone lines (at 9:1 concentration ratios) on a voice-over-broadband network, including:



Circuit-to-packet conversion—converts DS0s from the Class 5 switch into cell-based ATM format.



Routing—routes cells to and from IADs at subscriber locations.



Call administration—manages call-control signaling to both the Class 5 switch and the IADs.



Traffic management—monitors the connection over the access network to each end user.



Concentration management—supports line concentration levels up to 40:1.



System and Service Administration—acts as the administrative platform for managing voice-over-packet services.

Traffic Capacity

2-2 February 2003

The CPX supports up to 4,000 IADs, and supports two types of T1 modules, which may be used interchangeably: The Octal T1 module provides 8 T1 ports, and up to 6 modules may be placed in the CPX. Echo cancellation or echo cancellation and compression is provided on separate cards. The 12-port T1 ECAC module provides 12 T1 ports, and up to 7 modules may be placed in the CPX. Also, echo cancellation and compression is provided directly onboard, eliminating the need for separate EC or ECAC cards.

The CPX also supports two types of STS-1 cards, which may be used interchangeably. Up to 6 STS-1 cards may be installed in each CPX. The STS-1 module does not provide onboard echo cancellation or compression—you must use separate modules. The STS-1 ECAC module includes onboard echo cancellation and compression, eliminating the need for separate EC or ECAC cards.

The capacity of the CPX shelf configured with either T1 modules depends on the shelf configuration and the concentration and redundancy options selected.

A CPX shelf using either STS-1 or 12-port T1 card with ATM OC-3 can support over 2,000 simultaneous calls and 16,000 subscriber lines (8:1 concentration).

Carriers can upgrade the CPX network by adding additional CPX-1000s, all of which can be managed by a single JetVision workstation.

CPX-1000 Operation

Call control, circuit-packet switching, network interfaces, provisioning, and management, are divided into four basic functional blocks:

Management Processing

The Management Processor (MP) module is the administrative CPU for the CPX shelf. It acts as a database for the shelf and as an administrative interface for JetCraft, JetVision, and other management interfaces. The MP supports:



Configuration, fault, and security management for the CPX



Configuration management, fault management, and remote software upgrade of the IADs



High-performance, memory-resident database for persistent configuration



Real-time performance and error statics

The Embedded Operations Channel (EOC) process on the MP module handles the interface between the CPX shelf and the GR303 interface on the Class 5 switch. The EOC supports the following set of management services to the switch using the T1 model and GR-303 protocol stack:

1. The EOC process receives the management requests over the

EOC connection to the switch.

2. It then interacts with the management process to complete

these requests.

3. The management process notifies the EOC process about

changes in the operating status of the CPX-managed objects.

4. The EOC process sends this information to the Class 5 switch.

Call Processing The Call Processor Engine manages the connections between the

CPX shelf and the IADs at subscriber premises.

The Call Processor Engine resides on the redundant Call Processor (CP) modules that handle call processing, call-control signaling, call setup, and call tear-down.

The Timeslot Management Channel (TMC) process on the CP modules receive all call control signaling from both the Class 5 switch and the CP using the Q.921 (LAPD) data link protocol.

The IAD Signaling and Connectivity function manages communication between the CPX and the IADs. The information passed between the CPX and each IAD includes common channel signaling, alarms and events, and software downloads.

PSTN Interface The PSTN interface connects the CPX to the Class 5 switch via T1

or STS-1 lines. The Port Controller inserts framing and supervision signals into the TDM data stream. The PSTN interface then directs

2-6 February 2003

1000-A2-GN22-00 2. CPX-1000 Voice Services Platform Description

all signaling to both the TMC process and the CP. The PSTN interface controls all time slot mapping and CP functions.

The PSTN routes all voice timeslots over the voice bus to the packet interface.

The Voice Processing function switches individual timeslots between the TDM (T1/STS-1) ports and the voice bus. The Voice Processing function maps all incoming and outgoing voice data streams.

Packet Interface The packet interface physically connects the CPX shelf to the

packet network. The interface provides TDM data transport services over ATM using standard ITU and ATM Forum-compliant communications protocols.

This interface converts the information on the Bearer Bus to standard ATM cells and transmits these cells on the packet network. It also converts packet cells to voice timeslots. The Voice/Control Splitter directs the ATM cells (which contain call control and signaling) through the IAD Signaling and Connectivity function to the Call Processor Engine.

The CPX supports up to 4,096 unique PVCs (each representing one IAD). Each PVC (i.e., IAD) has a unique VPI and VCI assigned to it. The CPX supports 256 VPIs in the range of 0 to 255. IADs can be provisioned on any of these VPIs. The permissible range of VCIs per VPI is 0 to 1023. The maximum number of VCIs per VPI can be configured as one of five possible settings when the equipment is initially configured. The possible settings are:



1,024 (default)



512



256



128



64

Selection of the maximum of VCIs is determined by the network planner for what best fits the network topology.

In order to afford the maximum number of PVCs available from the CPX, IADs can be organized into IAD Groups. Groups are logical entities where IADs meet these criteria:



provisioned with differing VPIs but the same VCI

February 2003 2-7

2. CPX-1000 Voice Services Platform Description 1000-A2-GN22-00



the remainder of the formula is the same for all IADs:

VPI

(1024/VCIs per VPI)

For example, consider three IADs with the VPI/VCI pairs and where the maximum number of VCIs configured for the equipment is 256:

A. 32, 100

B. 36, 100

C. 38, 100

1. All three have the same VCI.

2. The maximum number of VCIs possible (1,024) divided by

the number of VCIs configured (256) equals 4.

3. Pairs A and B yield a result with no remainder when their

VPIs (32 and 36, respectively) are divided by the resultant of 1024 divided by 256: 32/4 = 8 with a remainder of 0 and 36/4=9 with a remainder of 0. (Pair C yields a different remainder: 38/4=9, remainder 2. Therefore, it is not in the same group with A and B.)

Physical Description

A maximum 4,096 IADs can be assigned. However, only 63 simultaneously active calls through IAD unlocked ports are allowed in any one IAD Group.

Note

IAD ports can be over-provisioned; however, only 63 can obtain dial tone at one time.



The active CP module handles all call processing activity, maintains all signaling, manages all IADs, captures statistics and alarms, and monitors all hardware in the system. It passes all this information to the management system.



The standby CP module mirrors the state information of the active CP module (i.e., all of the activity on the active CP module) and can take over at any time.

2. CPX-1000 Voice Services Platform Description 1000-A2-GN22-00

This architecture enables two types of CP module switchovers:



Automatic switchover—the system detects a problem with the active CP module and performs a forced switchover to the standby CP module. Mechanisms used to detect problems with a CP module include:

— Loss of a CP-to-MP (Management Processor) module

heartbeat

— Loss of a CP-to-CP module heartbeat

— Failure of a CP to respond to an “are you alive” ping

request from the High Availability software

— Failure of the High Availability software to detect a ping

request from the ping component on a CP module



Administrative switchover—the network administrator initiates a CP switchover using JetCraft or JetVision. A forced switchover always goes through regardless of voice traffic and active cells remain up.

Voice/Data Interruptionœ – possible

Calls that are in setup process are lost during a forced switchover. Calls that are already established and carrying voice traffic continue during a switchover.

Upon initiating a switchover, the previously active CP’s calls are assumed by the new active CP. After the switchover, the old active CP assumes the standby role (if all is well). CP switchovers do not automatically revert back.

Management Processor Module

The Management Processor (MP) module contains a processor, volatile and non-volatile RAM, and an Ethernet interface for administration.

The MP module is the administrative engine of a CPX shelf. It acts as a database for the shelf and as the administrative interface for JetCraft, JetVision and other management interfaces.

The MP module consists of two individual cards (Figure 2–8):



Management Processing card—processor and interface connections for monitoring redundant CP modules.



MP Transition card—I/O ports for connecting to the local area network and other peripheral devices.

The MP module hosts the CPX Management Entity, which features and supports:



Configuration, fault, and security management for the CPX



Configuration management, fault management, and remote software upgrade of the IADs



High-performance, memory-resident database for configurations persistence



Real-time performance and error statics

Two Ethernet ports are provided on the MP Card. Each port provides one connection to the CP A and B modules, configured to run at 100BaseTX Full Duplex. Each Ethernet port supports 10BaseT, 10BaseT Full Duplex, 100BaseTX, and 100BaseTX Full Duplex media types. It can detect the network media type to which it is connected, when the AutoDetect mode is selected (recommended in most cases).

On the MP Transition card, there are also 2 Ethernet connections, 1 and 2. Ethernet 1 is enabled and Ethernet 2 is disabled. On the front of the MP, there is also a third Ethernet connection marked “Ethernet”, which is the same as Ethernet 1 on the back. The back port is active, but the front Ethernet port is not active (unless there is no MP Transition card present).

PSTN Modules The CPX provides complete support of the GR-303 protocol,

including full GR-303 line concentration, all CLASS and calling features, full EOC, TMC, and path protection switching.

The CPX supports eight T1 interface groups (IGs). Each T1 port is independently assigned to an interface group, and each interface group supports up to 28 T1 ports. The CPX also supports path protection switching for the control channels in the GR-303 interface group.

T1 Load Sharing T1 load sharing is implemented by designing in excess capacity.

Overcapacity protection means the capacity of the T1 interface is maintained when one of the following failures occurs even at the busy hour call volume:



T1 module failure—oversize the capacity of the T1 interface for a fully operational system (Figure 2–9A) so that the interface can still handle the busy hour call volume even when one of the T1 modules has failed (Figure 2–9B).



T1 port failure—interface groups comprise T1 ports and are arranged across T1 modules so that IGs are shared among T1 modules (Figure 2–10). The shared arrangement provides a backup T1 port to each T1 module should one of the IG groups fail.

The illustrations below show how to implement primary and secondary module pairs, and group the T1 ports in Interface Groups across the cards, using Octal T1 cards for clarity.

When implementing PSTN using 12-port T1 ECAC modules, you attach the RJ-21X cable from each 12-port T1 card to a patch panel to split out each T1 port separately for connection as usual. T1 modules are paired as primary and secondary modules, and group the T1 ports into Interface Groups across cards in the same manner.

Caution

Do not put primary and secondary DS1 links on the same T1 module. Doing so prevents new calls from being made if one T1 module fails.

This architecture enables two types of STS-1 module switchovers:



Automatic/forced switchover—the system detects a problem such as loss of signal and performs a forced switchover to the standby STS-1 module in the protection group. When receive paths on an STS-1 module fails, processing switches over to the standby STS-1 module.



Administrative switchover—the network administrator initiates the switchover to the standby STS-1 module.

Each pair of redundant STS-1 cards has the following connections at the STS-1 splitter assembly (Tab le 2 –9 ):

ATM OC-3 Module

The ATM OC-3 module (coming in through the transition card) is the WAN interface that connects a CPX shelf to an ATM access network using an OC-3 optical interface. The ATM module performs real time circuit-to-packet conversion that allows an ATM-based access network to deliver local telephone service.

The CPX protects the ATM connection to the packet network against physical facility failure and far end equipment failure. In a switchover scenario, the CPX executes the transition from the working to the protection port to ensure no services are disrupted.

On power up, the presence of the ATM modules in the shelf is detected. Before ATM switchovers can occur, however, use JetCraft or JetVision to assign them to a protection group so that the primary and secondary modules can be designated. When the ATM modules are unlocked, the primary ATM module becomes active and the secondary ATM module becomes standby.

This architecture enables two types of ATM module switchovers:



Automatic switchover—the system detects a problem such as loss of signal and performs a forced switchover to the standby ATM module in the protection group.



Administrative switchover—the network administrator initiates a CP switchover using JetCraft or JetVision. A forced switchover always goes through regardless of voice traffic and active cells remain up.

Voice/Data Interruption

Calls that are in the process of being set up are lost during a forced switchover. Calls that are established and carrying voice traffic, however, survive a switchover.

The active and standby states for each ATM module is persistent. The CPX continuously monitors the health of redundant ATM modules and switches to standby ATM module if instructed to do so by software or user intervention. The CPX issues appropriate alarms and events to notify users that the switchover has been initiated and indicates the success or failure of a switchover.

CAUTION CLASS 1 LASER

Use of controls, adjustment, or performance of procedures other than those specified herein may result in hazardous, invisible radiation exposure.

The OC-3 ATM module includes the processing card only (Figure 2–16). The module supports capacity for 155 Mbits of information and can handle 1,024 simultaneous calls (DS0s).

Table 2–10 describes the controls, indicators, and ports.

OC-3 redundancy uses 1 + 1 protection, with a primary port that is active in the normal operating state and a secondary port in the hot standby state. The secondary port takes over if the primary port loses its connection.

Notes

Do not mix optical modes.

If you are using single mode OC-3 modules, use single mode optical cables. If you are using multimode OC-3 modules, use multimode optical cables.

Mismatching fiber cables may result in equipment damage.

Echo Cancellation and Compression Module (ECAC)

The ECAC module can be used with the Octal T1 or STS-1 module to provides compression from zero to 100% of calls on the CPX. With compression, maximum capacity is 1,024 calls. When ADPCM compression is used, samples are packed two per byte (32 kbps) or four per byte (16 kbps).

“Voice Compression” refers to the industry standard compression algorithm of voice data passed between the CPX and an IAD. Voice data compression decreases the bandwidth used on the most narrow pipe — the local loop — enabling additional voice calls and/or increased performance in data communications.

DC Power Distribution Panel

The DC power distribution panel includes two DC terminal blocks for connecting to redundant

−

48 Vdc input power supply (plant battery) and return branch circuits. An equipment power switch with a resettable circuit breaker provides a local control point for equipment power.

Input power circuits are wired so that the power supplies provide redundancy even when power supply A or B fails. The Power Distribution Unit (PDU) provides power from input power A to power supplies 1 and 2; input power B supplies power to power supplies 2 and 3. Thus, if either input power source fails, two power supplies are still functioning to retain power supply redundancy. Even if one power supply fails, the system may still perform under this stressed environment until the power supply and/or input power are restored.

The CPX requires –48 VDC plant battery power through two separate lines for –48V power and battery return (A and B). The power supply input voltage range is –40 V to –72 VDC, 13A maximum configured system (balanced between the two power supplies).

For external circuits, protect each branch with the appropriatesized fuse or circuit breaker (

≥

13A slow-blow). Maximum surge

during power-up is 40A for 4 ms to the shelf (20A to each supply).

The CPX measures 21 inches high × 17.2 inches wide (19 inches including mounting flanges)

×

17 inches deep. The STS-1 Splitter Assembly measures 3.4 inches high, 17.2 inches wide and 3 inches deep.

The CPX and STS-1 Splitter Assembly mounting flanges include hole spacings in EIA310, Bell Narrow, and Bell Wide racks. Installations in NEBS2000 racks require special rack mounting flanges. Ensure that you have the correct mounting flanges for your installation.

Electro-Static Caution

Use a wrist grounding strap, attached to the grounding jack on the CPX enclosure, when working with the system. ESD can seriously damage the printed circuit card assemblies and solid-state components inside the CPX.

To connect plant battery power and ground to the CPX, follow these steps:

Note

Do not apply power to the CPX until you finish all installation tasks. Ensure that the shelf circuit breaker is set to OFF/0.

Note

Be sure that all grounding connection surfaces are free and clear of contaminants.

Step 3 Set the rear circuit breaker to the Off/0 position (if it is not

already off).

Caution

Make proper polarity connections. Damage may occur to the circuitry when powered up if polarity is reversed.

Step 4 Remove the cover from the plant battery terminal strip.

Step 5 Connect the

−

48 VDC A and B outputs of the power source using two 14 AWG

−

48 VDC A and −48 VDC B terminals of the CPX to the

(or larger), stranded or solid wires terminated in #10 size compression ring lugs (Caltronics #RT-117, or equivalents).

Note

If you use 14 AWG wire, be sure that the plant battery power distribution point is no more than 40 feet from the CPX. Use a larger gauge wire if the power source is further away.

Step 6 Connect the Return A and Return B terminals of the CPX to the A

(+) and B (+) terminals of the power source as in step 5.

Note

The RTN A and RTN B terminals are also connected together inside the CPX enclosure.

3. Installing the CPX-1000 1000-A2-GN22-00

Verify Cabling Before proceeding with the final tasks of CPX installation, take

time to check your cabling, by verifying the following:

Step 1 ATM cables: The fiber optic OC-3 Transmit and Receive cables

connect the ATM modules to the ATM network.

Step 2 Ethernet LAN Connection: The MP Transition card connects to

the MP LAN connection using straight-through cables. Also ensure that the cable connects to the associated LAN port on the router.

Step 3 Host Switch T1 Cables: All T1 cables from the rear of the CPX

shelf are properly connected to the DSX. All connections should be made from the RJ48C patch panel, which in turn is connected via the 25-pair cable to the RJ-21X port on the 12-port T1 transition modules of the CPX shelf.

Step 4 STS-1 Cables: The CPX is connected to the Class 5 switch via 2

STS-1 cables connected from the STS-1 Splitter Assembly, and each STS-1 module in the CPX connects to the Splitter Assembly with two cables—Transmit and Receive— in a matched manner.

Apply Power After verifying CPX cabling, apply power to the CPX:

Step 1 Turn the circuit breaker on from the CPX rear panel.

Step 2 Verify that the CPX front panel POWER indicator is lit (directly

below the plug-in module cage).

Step 3 Verify that the INPUT indicators are lit on all power supplies.

Step 4 Verify that the fan in each power supply/fan module is running.

Check the Alarm panel indicators:

Indicators

Step 1 Verify that the APP indicator flashes on and off continuously

(one second on, one second off).

Step 2 Verify that all of the system status indicators are off (they are

not used).

Check the Fans The two CPX Power Supply Fan modules are equipped with an

integral fan assembly, and a third fan is supplied for redundancy (in case one of the other two fans fails).

Step 1 When power is first applied, the fans should run continuously,

circulating air through the system’s plug-in modules.

Step 2 Verify that the fans are running, and that the front vents on the

power supplies and the shelf rear vents are free of obstruction.

Verify Remote Interface

The CPX requires a remote connection for remote management. To verify the remote port operation after powering up the CPX, perform these tasks:

Connect JetCraft PC to CPX-1000

Change CPX Default IP

Make sure that JetCraft is installed on a PC. Connect the PC directly to the ETHERNET 1 port on the MP transition card.

For this connection, use a CAT-5 crossover cable with RJ-45 plugs.

The default IP address for the CPX is:

IP address 10.0.10.100

Address

subnet mask 255.255.0.0

3-34 February 2003

1000-A2-GN22-00 3. Installing the CPX-1000

In most cases, you should change the IP address of the CPX to one that can be detected by the network management software on your LAN. After you change the IP address, the CPX requires rebooting.

To change its default IP address, refer to the JetVision User’s Guide.

Verify CPX LAN Connection

Step 1 Verify that the MP Transition card is connected to the LAN hub or

Step 2 Ping the CPX from a PC on the same LAN as the CPX.
