1.0 General Description
The PT-CPC4400 is a Compact PCI (CPCI) based
Ethernet switch. There are twenty-four switched
10Base-T/100Base-TX ports, (2) 1000Base-TX/FX
Gigabit ports and (1) out-of-band (management)
10Base-T/100 Base-TX port. The switched, and out-of-
band 10/100M Ethernet ports are accessed from the
user-defined pins on the CPCI mid-plane connectors, P3
and P5. The Gigabit ports are accessed either from the
front panel or the CPCI mid-plane.
On-board magnetics allow the user to build the Ethernet
cabling into the mid-plane. Other CPCI based cards may
connect to the PT-CPC4400 via Ethernet over the mid-
plane, removing the often confusing and unreliable
mass of cabling found within most `Rack Area Network'
solutions. Alternatively, a rear panel I/O Line Interface
Module (LIM) can bring some (or all) of the Ethernet
interfaces out to RJ-45 connectors.

3.0 Applications
Due to its stand-alone architecture and CPCI chassis
compatibilty, the PT-CPC4400 is suitable for integration
into many types of high-availability (HA) as well as non-
HA Ethernet switching applications. These applications
include:
VoIP Media Gateway
Integrated Access Devices (IAD)
IP DSLAM Architecture
Integrated Server Farms
3.1 VoIP Media Gateway
The voice over IP media gateway application consists of
three major functional blocks. The Allocate, Convert and
Aggregate blocks make up the simplified bridge
architecture between traditional PSTN voice circuits and
the Internet.
Figure 1
shows a block diagram of a simplified media
gateway. In this example, the Allocate function allocates
circuits from the PSTN through a TDM switch to H.110
based DSPs. The DSPs serve to convert the PSTN
circuit into IP frames. The IP frames are collected and
aggregated into a high speed Ethernet uplink to be sent
over the Internet. Another PTI product, the PT-CPC395
Dual Channel T3/H.110 TDM Switch provides the
allocation function in this example.
Figure 1. VoIP Media Gateway
3.2 Integrated Access Device (IAD)
The Integrated Access Device consists of a gathering of
different types of digital and analog interface boards that
are commonly tied together through the CPCI Midplane.
The PT-CPC4400 provides a common Ethernet
interface for the assortment of devices. See
Figure 2
.
Figure 2. Integrated Access Device (IAD)
3.3 IP DSLAM Device
The IP DSLAM Device concentrates multiple xDSL
interfaces onto an IP packet Ethernet interface. See
Figure 3
. The PT-CPC4400 aggregates the traffic from
multiple xDSL line interface cards onto gigabit uplinks
for transmission over the Internet.
Figure 3. IP DSLAM Device
3.4 Integrated Server Farm
The Integrated Server Farm collapses an entire network
of servers into a single chassis. See
Figure 4
. The CPCI
chassis is populated with Servers attached to their file
systems. The PT-CPC4400 provides inter-connectivity
between the servers as well gigabit uplinks to the
Internet.

4.0 Model Numbers
The following models are described in this document.
PT-CPC4400--This model uses a fiber-optic interface
for the Gigabit ports.
PT- CPC4405--This model uses a copper-wire
interface for the Gigabit ports.
References made to the PT-CPC4400 also apply to the
PT-CPC4405 except where noted.
Refer to your PTI Sales representative for ordering
information.
5.0 Electrical
The PT-CPC4400 meets the electrical requirements
specified in the PICMG 2.0 R3.0 CompactPCI
specification.
5.1 Universal I/O
The PT-CPC4400 is a universal I/O board (no key on
J1), accepting either 5V or 3.3V for the PCI I/O signals.
5.2 Power Requirements
The power consumption of the PT-CPC4400 and PT-
CPC4405 are shown in
Table 1
.
5.3 Board To Board Interface
A set of signals are brought out to the CPCI backplane
via P5/J5 to support the integration of multiple PT-
CPC4400 boards in a common chassis for integrated
management support. This interface includes an I
2
C
interface for interboard communications and a set of I/O
signals that are connected between the set of PT-
CPC4400s in the system. The I
2
C interface is described
in
"PT-CPC4400 I2C Bus" on page 10
.
The I/O signals connected between the PT-CPC4400s
include a mastership signal (
MASTER
) and a set of 4
Board-to-Board (
B2Bn
) signals. When multiple PT-
CPC4400s are co-located in the same chassis and are
to be managed as a single entity, the user must provide
an interconnect between the boards using these signals.
Only one of the PT-CPC4400s should have the
MASTER
signal driven true (low) by the mid-plane, and all others
should have the
MASTER
signal driven high. The
B2Bn
signals should all be connected between all PT-
CPC4400s (
B2B1
connected to
B2B1
between all PT-
CPC4400s,
B2B2
connected to
B2B2
between all PT-
CPC4400s, etc).
All signals on the Board-to- Board interface support hot-
swap operation.
5.4 Port Connections
The PT-CPC4400 provides connectivity of all Ethernet
ports and the console port to the CPCI mid-plane via P3/
J3 and P5/J5. Some, or all of the ports can be brought
out to RJ-45 connectors on a rear panel LIM (Line
Interface Module). The remaining ports may be
connected to other slots in the system via the midplane.

The PT-CPC4400 supports twenty-four switched
10Base-T/100Base-TX ports, one out-of-band 10Base-
T/100 Base-TX port (port 27), and two 1000Base-TX/FX
ports.
The complete PT-CPC4400 connector pinouts are
provided in
"Pinouts" on page 17
.
5.5 Line Interface Options
The PT-CPC4400 supports three options for rear panel
connectivity. The Line Interface Modules (LIMs) provide
all required signals through J3 and/or J5.
25 Port LIM--The 25 Port Line Interface Module is a
double wide transition module that supports 25 ports.
This module provides access to all 24 10/100 Ethernet
Switched ports and the Out-of-Band Management
Ethernet port. All ports are presented via RJ45
connectors.
10 Port LIM--The 10 Port LIM offers 10 Switched 10/
100M Ethernet ports, the Out-of-Band mangement port,
and an RJ11 serial console port. Applications that utilize
embedded Ethernet signals in the CPCI mid-plane can
bring up to 10 ports out the rear and route the remaining
ports across the mid-plane.
This LIM may be customized by the user to bring out
fewer Switched Ethernet ports if needed. Please contact
your PTI Sales Representative for more information.
Rapid Architecturing Prototype Pak (RAPP)--The
RAPP LIM provides the user access to all of the PT-
CPC4400 mid-plane interface signals on a single slot
wide card. This LIM is not the standard LIM depth. It
extends beyond the natural card edge of the chassis,
and it is intended for prototyping purposes only.
All ports are presented on the RAPP LIM along with
extensive jumper options to enable and disable ports on
an individual basis and to provide port-to-port and port-
to-itself loopbacks.
The RAPP LIM is a vehicle used to aid the customer in
the development of a custom mid-plane with embedded
Ethernet cabling.
6.0 Mechanical
The PT-CPC4400 meets the mechanical requirements
specified in the PICMG 2.0 R3.0 CompactPCI and the
IEEE 1101.11 specifications.
6.1 Form Factor
The main board is a 6U (233.35 mm by 160 mm) board
size. All Rear Panel I/O LIMs (Line Interface Modules)
are also 6U size (233.35 mm). LIMs (except the RAPP
Prototyping LIM) are 80 mm in depth for standard
applications. The 24 port LIM is a double wide board.
Single wide LIMs are also available with up to 10
switched Ethernet ports, a management Ethernet port,
and a console port.
6.2 CompactPCI Connectors
The board uses standard 2 mm Type AB CompactPCI
connectors. The PT-CPC4400
does not use connector
J4. The switched Ethernet ports, the console port, and
the non-switched (out-of-band) management port are
presented to the CPCI mid-plane via J3 and/or J5.
6.3 Front Panel
The PT-CPC4400 provides a front panel compliant with
IEEE 1101.10. The PT-CPC4400 front panel provides
an RJ-11 console port connection and visibility and
identification of all LEDs for ports and system status.
The PT-CPC4400 front plate also provides access to
two SC-duplex connectors for the Gigabit Ethernet
ports.
7.0 Switched Ethernet Ports
The PT-CPC4400 provides (24) 10/100M Ethernet ports
and (2) 100/1000M Ethernet ports interconnected in a
full mesh by 802.1d MAC Relay Entities. That is, a
bridge function exists between any switched port and
any or all of the remaining switched ports. The switched
Ethernet ports offer low latency, wire-speed, Layer 2
and Layer 3 IP switching performance on all ports
simultaneously.
