1Overview

The PX3 platform is an integrated packet-switching module for the
N.E.T. Promina Series Multiservice Access Platform nodes. The PX3
platform provides packet-switched services over a wide area network and
is the engine that drives the N.E.T. packet-over-circuit architecture.

This chapter provides an overview of the PX3 platform which consist of a
front and a rear interface card. The sections in this chapter describing the
PX platform, applications, and Promina software are:

• PX3 Platform on page 1-2.

• Applications on page 1-4.

• Promina Software on page 1-6.

• PX3 Card Connectivity on page 1-7.

Overview

PX3 Platform

PX3 cards deliver high throughput for frame- and packet-switched traffic.
The PX3 ports handle input/output packet data. By transmitting multiple
frames in parallel, the PX3 card increases the efficiency of input/output to
the wide area network. The PX3 platform consists of a front card and
optional rear interface cards. The PX3 front card family consists of three
versions:

• PX3-4 Port

• PX3-8 Port

• PX3-16 Port

Users can leverage their investment in existing Promina equipment while
implementing state-of-the-art packet processing.

Front Card

Features

The PX3 front card includes an onboard processor and high speed serial
ports. PX3 serial ports can be connected to remote PX3 modules or to
local or remote data cards with external serial ports. The PX3 card has an
instruction cache and data cache. Increased memory provides additional
buffers for user traffic and memory for system tables (for example,
topology, route, and system data).

Software applications for the PX3 are stored directly on the card in
onboard flash memory. This allows faster reloads and permits redundant
software images which simplifies the upgrade process.

LEDs on the PX3 platform front panel indicate the status of the module.
For example, the Heartbeat LED indicates the overall health of the card,
while the Power LED indicates the card is receiving power. Refer to
Figure 3-2 for more details regarding the LEDs.

PCMCIA Card

The PX3 front card can use an optional PCMCIA card to facilitate backup
of configuration files and to upgrade software images.

Optional Rear

Interface Cards

The PX3 platform provides the following optional rear interface cards:

• T1/Ethernet

• E1/Ethernet

• Ethernet

• Token Ring

The T1 and E1 cards provide dynamic programmable channel allocation
and CRC-16 generation and checking. The interface cards can be
swapped without switching off power (“hot swapped”). The T1 and E1
interface cards have their own processor and therefore execute code
independent of the PX3 front card packet memory option.

The T1, E1, Ethernet, and Token Ring interface rear cards are available
for all PX3 models.

With the T1 and E1 interface cards, the PX3 supports access from
groomed carrier services. The T1 card supports up to 24 channelized
DS0s for a T1 trunk; the E1 supports up to 31 channelized timeslots for an
E1 trunk. These channels may be aggregated to form higher bit rate
signals with no requirement that they be contiguous. Both the T1 and E1
interface cards provide a 10BaseT port to support management console
access and diagnostics.

Overview

Applications

The PX3 platform supports the following networking applications: LWX
(LAN/W AN Exchange), FRX (Frame Relay Exchange), and PrimeSwitch
Module.

FRX Frame Relay Exchange (FRX) is N.E.T.’s solution for frame relay

networking. FRX networks enable an organization to provide frame relay
services over public or private trunks, or a hybrid public/private network.
FRX systems are designed to fulfill the following roles in hybrid frame
relay networks:

• Central switches that emulate hubs routing a large number of circuits
for frame relay traffic.

• Concentrator switching nodes that consolidate traffic from many
sources into a single or smaller number of circuits.

LWX The LAN/WAN Exchange (LWX) application is a general purpose

router/bridge application integrated into the Promina Series platform,
providing internetwork connectivity between LANs over WANs that
contain Promina Series nodes. The LWX application is used in
conjunction with a PX3 front card and an Ethernet or Token Ring
interface rear card, and provides:

• concurrent multi-protocol routing and fallback MAC layer bridging

• up to eight logical serial connections to other LWXs or external

routers

PrimeSwitch N.E.T.’s Promina Series provides a network interface for an Integrated

Services Digital Network (ISDN). Promina Series supports the following
interfaces:

• The Primary Rate Card (PRC)

• The Two-Megabit Channelized Port (TMCP) module

• The Quad Basic Rate Interface (QBRI) module

These interfaces enable a private ISDN network to be established
between Promina and IDNX platform products is 0. nodes, transforming
the N.E.T. wide area network (WAN) into a dynamic communications
resource that allocates bandwidth on demand, optimizing the use of the
backbone network. Connections can also be from any of these module
types to off-net public ISDN services.

Module Installation

Installation Requirements

This section describes how to estimate logical slot requirements, load
units, and power consumption; Promina shelf restrictions; and PX3
platform connectivity to data ports.

Logical Slots Logical slots measure a module’s backplane bandwidth requirement (one

logical slot equals 2.048 Mbps of bandwidth). Logical slots must be
calculated to determine whether a configuration exceeds the logical slot
constraints for a shelf.

Note: For information on logical slot requirements, see the Quick Reference
Guide of the Promina Series documentation set.

The PX3 card is a multi-rate card. The PX3 supports up to 4.096 Mbps of
bandwidth per port. For the PX3 card, logical slots are assigned on a per
port basis and vary depending on the aggregate bandwidth and port
speeds.

The logical slots are based on the data rate selected by the user (refer to
Table 2-1).

Table 2-1 Port Speed and Logical Slots Requirements

Port Speed Logical Slots

Up to 64 kbps 0.03125
Up to 128 Kbps 0.0625
Up to 256 kbps 0.125
Up to 512 kbps 0.25
Up to 1.024 Mbps 0.5
Up to 2.048 Mbps 1.0
Up to 4.096 Mbps 2.0

Load Units A load unit is a measure of the processor processing capacity. The PX

platform front card has a microprocessor unit (MPU) on board and does
not draw load units from the processor on the Promina node. Refer to the
Quick Reference Guide of the Promina Series documentation set for more
information.

The individual port speeds are adjustable from 9.6 kbps to 4.096 Mbps on
all Promina platforms.

The serial ports are available in four port groups: ports 0-3, ports 4-7,
ports 8-11, and ports 12-15. The maximum allowable throughput for each
group of four ports is 8 Mbps, up to 32 Mbps per card.

In a Promina 800 node, speeds greater than 2 Mbps are available.
Consequently, it is important not to exceed the 8 Mbps per group
bandwidth requirement as described above. For example, in a Promina
800 node, if port 0 is 4 Mbps, and port 1 is 4 Mbps, then ports 2 and 3
should not be used.

Note: Although all 32 Mbps (16 x 2 Mbps) can be configured, there is a limit
based on available TBus and PX3 card switching capability.

Database Installation

Overview

After the PX3 platform is physically installed (described in Chapter 2,
Module Installation), it must be configured as part of the Promina wide

area network (WAN). To database install the PX3 platform, there are two
required steps to be performed from the Promina Interface Menu:

• install and configure the card (Install Card command)

• install and configure the ports on the card (Install Port command)

Promina database installation provides the PX3 based applications the
following:

• virtual connect capability (card install)

• access to physical connections (TBus) for serial ports (port install)

• access to the CBus

Use the Query Card and Query Port commands to display PX3
platform configurations. Use the Modify Card and Modify Port
commands to change PX platform card and port configurations.

The Promina Interface Menu does not configure the functionality of the
PX3 based application ports; these are configured through the application
interface menu.

Note: The PX platform can provide clock references if it has a T1 or E1 rear
card. The T1 or E1 facility is used for the clock source, for example the Ethernet
interface.

Note: For additional information about the Operator Interface, OI menus, and
expert mode, see the Promina Series Node Management manual as well as the
Operator Interface Command Summary in Appendix A.

prevented from taking that path and rejected on a call by call basis. For
interdomain calls, the cumulative link cost is reset upon entering a transit and/or
destination domain. This means the cumulative link cost is bounded on a per
domain basis for interdomain calls.

[0] Originate/Answer Mode

Options are Ans-only (default), Orig-only, and Orig/Ans.
This parameter specifies whether the port can originate and answer calls,

answer calls only, or originate calls only. Originate/answer and
originate-only ports require a destination port.

[1] Destination Port/Bundle

This option is selectable only if this is Orig-only, or Orig/Ans.
The setting for the destination port ID is the destination port that

communicates with the origination port.
This parameter is required for originate/answer and originate-only ports.

The type of destination ports the PX platform can communicate with
depend on the release of the Promina software.

With Promina Release 1.x1, the PX platform can connect to clear channel
ports on a TRK-3 (span mode). This parameter is listed as [1] Destination
Bundle when parameter [11] TRK-3 Clear Channel Port is set to Yes.

With Promina Release 1.x1, the PX3 card can connect to several
destination ports, for example, HSD-2, CX, or PRC. For a complete list of
PX3 platform connectivity refer to Table 2-3.

[2] Call/Preempt Priority

These parameters apply to answer and originate-only ports, but not
answer-only ports.

The range for Call Priority is 0 (lowest) through 15 (highest). The default
is 7. The range for Preempt Priority is 0 (lowest) through 15 (highest).
The default is 0.

Although they appear on the screen as one item, these are two
independent parameters. They work together to determine which call is
placed or reconnected.

Call priority determines the order in which a call originating from this
port is reconnected when the port is interrupted for any reason. A port

Database Installation

with a high call priority is reconnected before ports of lower call priority,
but after ports of higher call priority. When all ports have the same call
priority, there is no particular order for reconnection.

Call priority is also used to determine whether a call originating on a port
can be preempted when there is insufficient bandwidth on the link to
handle all calls. Call priority and preempt priority work together in
making this determination.

Preempt priority is used when there is not enough bandwidth to complete
a call. The preempt priority value assigned to the call is compared to the
call priority value assigned to other calls on the link to determine which
calls should be preempted. Calls having a call priority value lower than
the value of the preempt priority call are preempted. The preempted call
is placed when enough bandwidth is recovered.

To prevent certain calls originating on other ports from being preempted,
assign them a call priority that is higher than the value of the preempt
priority. Although preempt priority ensures that the call obtains
bandwidth, it does not mean that the call will be completed if the
destination port is busy.

[3] Secondary Call/Preempt Priority

The range for Secondary Call Priority is 0 (lowest) through 15 (highest)
and the default is 7. The range for Secondary Preempt Priority is 0
(lowest) through 15 (highest) and the default is 0.

The description and values are similar to [2] Call/Preempt Priority , but [3]
takes effect on a secondary basis. When a call is trying to build on the
optimal path, it uses the primary set of priorities defined by [2]; if the
optimal path is not available, the call uses the secondary priorities.
Optimal path is defined as a selected path fulfilling the routing
preferences and employing the least number of hops and least cost.

[4] Port Speed

The port speeds available depend on the data format and the type of node
in which the PX platform is installed. A higher bandwidth is available for
a PX platform installed in an Promina 800 than for a PX platform
installed in a Promina 400. For more information about the modules that
support 9.6 and 19.2 kbps asynchronous call rates, see the Promina Series
Data Module manuals.

Port speeds listed in this section are available for PX platform to PX
platform connections. The following section discusses PX3 specific port
speeds (Table 4-1). Port speeds available for PX platform to data port

connections vary depending on the type of data port. For more
information, refer to [1] Destination Port/Bundle on page 4-15.

The port speeds shown include the maximum speeds that can be
configured. The actual reliable port speeds may be lower, depending on
the following factors: trunk speed; the application of the PRC or TMCP
cards; the model number of the Promina; and the PX platform card in use.

For Promina nodes, the PX3 card supports asynchronous call rates of 9.6
and 19.2 kbps. This makes these PX platforms suitable for connection to
any data card that supports trunk asynchronous call rates of 9.6 and 19.2
kbps, including the HSD-2, QSD-2, and QASD cards.

Table 4-1 lists the port speeds available in Nx64, Normal 64, Nx56, and
Normal 56 data formats.

Note: The port speeds shown in Table 4-1 include the maximum speeds that
can be configured. The actual reliable port speeds may be lo wer, depending on
the following factors: trunk speed; the application of the PRC, TMCP, or NGS
cards; and the model number of the Promina.

[5] Time-of-day Restriction

The time-of-day restriction specif ies a start and end time for the port. The
default is None.

This parameter is used when the call can only originate during a specific
time of day. The call is torn down when the time has elapsed.

With originate-answer ports, the destination port is not affected.

Database Installation

For permanent calls, when the same start and end times are specified, the
call is torn down and replaced every day at that time. This technique can
be used to optimize the path used. The call will not be torn down when it
is already on an optimal path.

[6] Routing Options

This parameter specifies the routing requirements for terrestrial routing,
encryption routing, ATM, SCLX, and fiber routing. The possible settings
for each of these routing options are Don’t Care (default), Prefer Not,
Preferred, and Required.

Use the routing options parameter to specify the routing method for a
specific application. For example, selecting Fiber can indicate any
operator-defined routing method.

• Don’t Care specifies that any available path is used.

• Prefer Not specifies that certain paths are used when no other paths

are available. The call is not blocked.

• Preferred specifies that certain paths are used first. If those paths are

not available, any path is used. The call is not blocked.

• Required specifies that only certain paths can be used. If those paths

are not available, the call is blocked.

Note: Refer to the appropriate application manual for guidelines.

[7] Primary Selected Path

Up to 12 node IDs, including intermediate nodes and the destination
node, can be specified in a selected path. When specifying more than one
node, separate the node IDs with a comma. The same node cannot be
specified more than once. The default setting for this parameter is None.

This parameter allows the user to override the system and specify the path
the call takes through the network. This provides for full end-to-end
management of the call from the originating node, through the transit and
destination domains, all the way to the destination node.

When creating a path, confirm that it meets the port’s routing attributes.
Up to 255 selected paths can be created. Only one path can be specified
per port, but specified paths can be shared among ports.

After a path is created, it is placed in the path select table, where it can be
queried or deleted. When a path is deleted from the path select table, all
ports using that path are changed to None.

When no path is specified or the selected path is unavailable, the system
determines the best path.

[8] Data Format

This parameter can be set to Nx56, Nx64 (default), Normal 56, or
Normal 64.

Note: Refer to Table 4-1 for port speeds.

This parameter specifies the type of data format used on the port. When
Nx64 is selected, all bits in the data stream are used. Choose Nx56 format
when data passes through equipment that requires the ones density
format. Nx56 uses seven bits of the stream for data, with the eighth bit set
to one. Normal 64 format can be used for SDLC inter-networking and
lower speeds.

[9] Data Flow Direction

This parameter can be set to Two Way Call (default), One Way Inbound,
or One Way Outbound.

This parameter is used to define the direction of the data flow. This
parameter is used in conjunction with one way call and asymmetric
trunks (SA-TRK module). Most data ports have this option, although it is
not necessary for all applications.

One Way Inbound specifies that the data only flows from the originate
port to the answer port. One Way Outbound specifies that the data flows
from the answer port to the originate port.

For more information on one-way and two-way calls associated with the
SA-TRK, refer to Promina Series Trunk Modules.

[10] Path/Selected Path Required

This parameter can be set to Yes or No.
When the parameter is set to Yes, calls are restricted to the path specified

in the selected path field. When no selected path is specified, this
parameter is inactive.

The path required parameter prevents the system from rerouting calls
from the selected path to a different path. When the parameter is set to
No, the system can reroute calls from the selected path to a diffe rent path
when there is a network failure.

[10] Selected Path Required is available to nodes running IDNX Release

12.x2 or later software.

Note: Refer to the appropriate application manual for guidelines.

[11] Clear Channel Port

Value is Yes or No (defualt).
This parameter can be set to Yes or No. Set this parameter to Yes to enable

the TRK-3 clear channel port. Data format must be set to Nx64 for
connection to CX VBR/CBR ports.

Note: This parameter can be used to connect to any port bundle (for example,
CX, SCLX, for an IP-TRK port bundle), not just a TRK-3 clear channel port.

Actual Path

This field shows the path the port is using to complete a call through the
network. The origination node is listed first, and the destination node is
listed last. Any nodes in between are intermediate nodes through which
the call passes to arrive at the destination node.

This field also indicates whether the path is an optimal path (OP) or a
non-optimal path (NOP). When a call is reconnected through an optimal
(that is, least-cost) path, OP is displayed to the right of the actual path
field. If there is insufficient bandwidth and a call is connected through a
non-optimal path, NOP is displayed.

Call State

This field shows the state of the call when the port is queried. The
possible call states are:

• Answer disconnect—When in the awaiting answer state, the port is
disconnected. When the call is answered, it is disconnected.

• Awaiting answer—The port originated a call and is waiting for
confirmation from the destination port before it completes the call.

• Awaiting connect (orig) and awaiting connect (dest)—The circuit is
built, and the node is waiting for a connect acknowledgment before
signaling to the terminal that the call is up (carrier detect comes up).
When the destination port is configured for an answer signal, the
origination port remains in the awaiting answer state until the
destination port responds.

Replacing an

Identical Front

Card

Follow these steps to replace a PX3 front card with an identical card.

To replace a PX3 front card with an identical card

Note: Ensure that the same type of PX3 card is being replaced. For example,
you must replace a PX3 4-port module with another PX3 4-port module with the
same assembly number and revision level. The same rule also applies to the 8­and 16-port PX3 modules.

1. Save the configuration files to a remote host or to flash memory. For

application configurations, refer to the appropriate application
manual.

Note: When replacing the front card on a PX3, transfer the flash memory card
from the original card to the replacement card to retain the original code image
(such as FRX, LWX, or PrimeSwitch). In some cases, it may be necessary to
transfer the DRAM. Refer to Switching Flash Memory on the PX3 on page 5-14.

2. Disable the PX module using the Disable Card command.

3. Open the cabinet front door.

4. Remove the front card by rotating the two ejector arms on each end of

the card. Slowly pull the card from the shelf, being careful not to
disturb the adjacent cards.

5. Confirm that the slot number is correct, then insert the replacement

card as shown in Figure 5-2. Seat the card in the slot by rotating the
ejector arms toward the center of the card, locking the arms inside the
shelf front edge.

Upgrading the

Front Card

Use this procedure to delete the old card type from the Promina database;
physically upgrade the front card (such as, a PX3 with an upgraded PX3);
and update the Promina database with the new card type.

Note: If the Promina database is not updated, when the Quer y Card command
is used, the PX3 will fail to load. Configuring the new card in the Promina
database is described in Chapter 4, Database Installation.

To replace a front card with an upgraded front card

1. Save the configuration files to a remote host or flash memory. Refer

to the appropriate application manual for application configurations.

2. Open the cabinet front door.

3. Remove the front card by rotating the two ejector arms on each end of

the card. Slowly pull the card from the shelf, being careful not to
disturb the adjacent cards.

Note: When replacing the front card on a PX3, transfer the flash memory card
from the original card to the upgrade card to retain the original code image
(software application such as FRX, LWX, or Prime Switch). In some cases, it
may be necessary to transfer the DRAM. Refer to the Switching Flash Memory
on the PX3 on page 5-14.

4. Confirm that the slot is correct, then insert the replacement card into

the slot. Seat the card in the slot by rotating the ejector arms toward
the center of the card, locking the arms inside the shelf front edge.
