This chapter describes the Paradyne Jetstream Voice-over-
Broadband (VoBB) product solution, including the following
topics:
Local Access
Network
Architecture
The modern packet-based local access network enables Integrated
Communication Providers (ICPs) to deliver a combination of voice
and data services to their subscribers over the local loop.
Our Voice-over-Broadband (VoBB) local access network
Voice over DSL (VoDSL)—enables the delivery of
integrated high-speed voice and data services over a single
DSL circuit; that is, over a single copper pair.
Voice over T1 (VoT1)—offers access at greater distances
(i.e., hundreds of miles when repeaters are used) and
provides guaranteed bandwidth. It also uses existing T1
aggregation resources at the ILEC central office.
Voice over Wireless (VoWLL)—eliminates the need for
land line copper loops by using ATM over MMDS or U-NII
wireless broadband access networks.

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
more efficient use of copper connections between the
subscriber premises and the Class 5 switch
CPX-1000
Voice Services
Platform
The CPX-1000 supports any broadband access network technology,
including voice-over-T1, voice-over-DSL, and voice-over-wireless
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.

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.

1. Voice-over-Broadband Networking
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

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
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.

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.

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 GR-
303 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

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

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.)
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.

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.

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
the interface can still handle the busy hour call volume even
T1 port failure—interface groups comprise T1 ports and
are arranged across T1 modules so that IGs are shared
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.

2. CPX-1000 Voice Services Platform Description
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.

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
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
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).

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.

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 appropriate-
sized fuse or circuit breaker ( 13A slow-blow). Maximum surge
during power-up is 40A for 4 ms to the shelf (20A to each supply).
Rack
Requirements
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.

Attach the
Mounting
Flanges
The CPX ships with a pair of reversible mounting flanges for either
a 19-inch or a 23-inch standard or seismic rack. One orientation of
the mounting flanges fits a 19-inch rack, and the reverse
orientation fits a 23-inch rack.
Note
These flanges work in EIA310, Bell Narrow, and Bell
Wide racks. Installation in NEBS2000 racks requires
special mounting flanges, a separately orderable option.
Step 1
Attach the flanges to the CPX chassis with the 10-32 pan head
screws with integral-toothed lock washer (provided).

3. Installing the CPX-1000
Rack Mount
the CPX
You can install up to three CPX shelves in a standard or seismic 7-
foot-tall, 19-inch or 23-inch relay rack. If you plan to install more
than one CPX, mount the first unit in the bottom of the rack.
Otherwise, select a height consistent with local practices for
partially loaded racks.
Clearances shown are recommendations, based on industry
standards. Your specific installation may vary.

DS-1 Cables
Attaching Cables
to Octal T1
Modules
Connect the host switch T1 cables to the CPX:
Note
T1 cables for the Octal T1 module require RJ-48C plugs
on the CPX end for these connections. To facilitate the
connections, label each cable by its destination port at
the host Class 5 switch.
Step 1
Following the installation engineering and provisioning
documentation, map the T1/DS-1 connections from the host switch
to T1/DS-1 groups.
Each T1 connection is assigned a T1/DS-1 group number and an
individual connection number, such as 1-1. T-1 #1 must connect to
T1/DS-1 #1 at the Class 5 switch, etc. A T1/DS-1 interface group is
the logical administrator of the T1s. The minimum number
required for an interface group is 2.
Step 2
Connect the T1/DS-1 spans to the T-1 transition modules in the
back of the CPX shelf.
Note
T1 jacks are numbered 1–8 or 1–12 (#1 is located at the bottom).

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
Step 4
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.
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:
Turn the circuit breaker on from the CPX rear panel.
Step 1
Step 2
Verify that the CPX front panel POWER indicator is lit (directly
below the plug-in module cage).

is lit to indicate that the CP and HSC cards are powered, and the
ERROR indicator is off.
Management Processor (MP) Indicators: Verify that the
PWR indicator is lit, and the Link indicator is lit to show that a
communication link is established with the CP card. The ACT
indicator lights when the module is in use.
Step 4
Step 5
ATM Module OC-3 Indicators: Verify that the STATUS
indicator blinks to indicate heartbeat is present. (STATUS lights
solid when there is a problem). The Tx and Rx indicators will light
when data transmission and reception occurs.
Octal T1 Module: Verify that the green RUN indicator is lit, and
the FAIL indicator is off. Each port indicator light should be off.
They light when carrier fails, or no carrier is present. The blue Hot
Swap indicator should also be off. The Power indicator on the
corresponding transition card should be lit.

Check the Alarm panel 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
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.

General
Troubleshooting
Guidelines
Use the following list as general guidelines:
Work from the general specific—start with simple
things first —check the power source, check for loose cables,
and ensure CPX components are properly seated.
Make no assumptions—but, check what is logical to
check.
Approach the problem systematically—Whether you
suspect a hardware or a software problem, make only one
change at a time. If that does not resolve the problem, put
the item or setting back the way it was and proceed to the
next step or component.
Document everything—keep notes about the problem
and the various steps to resolve the problem. Document
your suspicions about the cause of the problem. Develop a
troubleshooting action plan.
Identify the symptoms—get as much information as you
can:
— What changes to operation or performance occurred?
— Check equipment for red fault lights.
— Check appropriate error files/logs for clues.
Console).
Identify possible causes—problems often occur as a
result of system changes.
— Was software installed, removed, or upgraded?
— Did a power surge or outage occur?
— Was equipment moved; were components added,
swapped or removed?
— Were changes made to the facility that could have an
effect on the problem?
— Were changes made to network configuration (at the
IAD, DSLAM, Packet Switch, or Class 5 switch)?
— Is the problem reproducible?
— Is this the first time the problem has occurred?
— Is there a pattern? Does the problem occur at a specific
time of day or after a certain action such as system
backups?
— Is the problem with one CPX or several?

Note
The Splitter Assembly is part of the STS system. The Splitter
Assembly provides card redundancy by splitting receive and
transmit signal to two STS cards. The active STS card receive and
transmits signal. The standby card only receives signal.
The Splitter Assembly is shipped with BNC terminators in place to
prevent signal degradation. The terminators should be left in place
until an STS cable is connected, and should be replaced if the cable is
removed.
When pulling cables on STS systems, disconnect the cable at the
splitter end first, and immediately install a terminator. Then,
disconnect the cable at the STS card end. When reconnecting, connect
the cable at the splitter end first. Then, remove the terminator at the
splitter assembly and immediately connect the STS cable.
The BNC terminators should also be used if the Splitter Assembly is
used in a non-redundant environment. For example, customers who
order the splitter assembly with the intent to upgrade later to
redundancy should keep the terminators in
place.

Power System
Troubleshooting
The CPX requires 48V power from a plant battery source. Two
48Vdc inputs (A and B) are wired to the CPX, so that if one input
to the system fails, the other maintains power. Input A delivers
power to the left and center power supply modules; Input B
delivers power to the center and right power supply modules.
The CPX has three load-sharing power supplies, which deliver dc
voltage to all of the plug-in modules. A circuit breaker located on
the CPX rear panel, provides equipment electrical protection
