Model 6511RC Matrix Switch overview
The Model 6511RC Matrix Switch (see figure 1) combines TDM aggregation and cross-connection with highspeed packet switching over synchronous digital hierarchy (SDH) and Ethernet uplinks for the Patton ForeFront Access Infrastructure Solutions (AIS) system. The web-manageable Matrix Switch provides a fully nonblocking mapping and switching matrix for TDM and Ethernet traffic traversing the ForeFront chassis or chassis segment. With the Model 6511RC, ForeFront AIS can deliver aggregated TDM and IP traffic on highspeed SDH and Ethernet trunks. The Matrix Switch is designed for installation and operation in either the
ForeFront Xtreme Model 6676 cPCI 9U chassis or the ForeFront FullPipe Model 6476 6U chassis. Each
model 6511RC Matrix Switch includes an on-board TDM multiplexer, a powerful Ethernet switch, a 155
Mbps SDH/STM-1 trunk port, and two 10/100/1000 Mbps Ethernet interfaces for high-speed packetswitched uplinks.

Matrix Switch front blade
Model 6511RC User Manual 1 • Introduction
Figure 2 shows the major functions and connections the Matrix Switch provides within the ForeFront chassis.
Each Model 6511RC enables service providers to perform SDH multiplexing and demultiplexing with any-toany timeslot mapping for up to 2048 DS0 channels. The on-board TDM multiplexer can map any of the 4096
DS0 timeslots on the TDM bus in the chassis midplane to any of the 2048 DS0s on the STM-1 uplink. Each
DS0 consists of a 64 kbps communication channel, or timeslot. The integrated SDH aggregator combines
DS0 channels into E1 signal streams, then maps those E1s into a STM-1 signal for high-speed transmission on
the SDH trunk.
Figure 2. Model 6511RC Matrix Switch major functions and interfaces
The Model 6511RC provides an Ethernet-switching fabric for packet-based management and user traffic traversing the ForeFront chassis. The powerful Ethernet switch connects the high-speed packet-switched bus in
the ForeFront chassis midplane with two 10/100/1000 Ethernet uplinks. Offering fast Ethernet switching and
flexible timeslot aggregation, the Model 6511RC Matrix Switch enables the ForeFront AIS system to deliver a
surprisingly compact, high-speed trunking solution at very low cost.

Three versions of the rear card offer the following connector types for the STM-1 port:
• SC20—Optical interface presented on Rx and Tx SC connectors for singlemode fiber with a wavelength of
1310 nm. The interface complies with ITU specifications G.957 and G.652.
• EBNC—Electrical interface presented on Rx and Tx 75-ohm BNC connectors.
• SC20/EBNC—Optical and electrical interfaces as described previously.
The Model 6511RC connects to other blades in the chassis via the ForeFront cPCI chassis midplane. The chassis mid-plane contains two digital communications busses, the H.110 TDM bus, and the PICMG 2.16
Packet-Switched Ethernet bus. The front blade connects to both busses via connectors on the chassis midplane. The blade uses the two mid-plane busses for digital communications with other processor blades
installed and operating in the chassis.

ForeFront chassis architectures
The Model 6511RC can be installed in the following ForeFront cPCI chassis:
• Model 6476 6U chassis
• Model 6676 9U chassis
ForeFront Model 6476 6U cPCI chassis
The ForeFront Model 6476 6U cPCI chassis provides 8 slots for installing cPCI processor blades (see figure 7).
The Model 6476 chassis accepts up to two Model 6511RC blades, installed in the fabric slots (designated by a
yellow blade guide). Using the H.110 TDM and PICMG 2.16 packet busses residing in the chassis mid-plane,
an installed Model 6511 can communicate with the other blades installed and operating in the remaining slots.

Figure 8. Model 6676 chassis, front view
The ForeFront Model 6676 9U chassis
The ForeFront Model 6676 9U chassis offers 17 slots for installing cPCI processor blades (see figure 8). The
Model 6676 midplane is divided into segment R (slots 1 through 8) and segment L (slots 9 through 17). Each
mid-plane segment contains its own H.110 and PICMG 2.16 bus, so since each 6511RC connects to one midplane segment, two Matrix Switch blades, installed in each of the two segments, are required to serve an entire
Model 6676 chassis. The Model 6676 chassis can accept up to four Model 6511RC blades installed in slots
called fabric slots (slots 1, 2, 9, and 10) designated by yellow card guides. In each backplane segment, a maximum of two 6511RC blades can be installed for operation to provide switching functions for that segment.

capacity of the STM-1 uplink on the Model 6511RC is 2016 full-duplex DS0s, the equivalent of 63 E1 lines.
The following sequence describes the process by which the Matrix Switch maps and multiplexes 63 E1 streams
into the architecture of the STM-1 signal stream:
• E1 -to- C-12 -to- VC-12 -to- TU-12 -to- TUG-2 -to- VC-3 -to- AU-3 -to- AUG-1 -to- STM-1
Multiplexing occurs at the following points in the mapping sequence:
- Three TU-12s are multiplexed into one tributary unit group-2 (TUG-2).
- Seven TUG-2s are multiplexed into one TUG-3 or administrative unit-3 (AU-3).
- Three AU-3s or TUG-3s are multiplexed into one administrative unit group-1 (AUG-1).

Matrix Switch TDM capacity
The Matrix Switch provides the means for you to map any DS0 on the H.110 TDM bus to any DS0 on the
STM-1 trunk and vice-versa. The difference in capacity between the H.110 bus and the STM-1 link is 64 halfduplex DS0s, the equivalent of one E1 line. The STM-1 uplink provides sufficient capacity to aggregate 98%
of the traffic capacity of the H.110 TDM bus. The Model 6511RC provides the capability to map and aggregate traffic on the H.110 bus up to the full capacity of the STM-1 trunk.
Matrix Switch Ethernet Switching
The Matrix Switch also delivers Ethernet connectivity and switching for any Ethernet traffic traversing the
PICMG 2.16 bus to which the blade is connected. The Model 6511RC provides the Ethernet switching fabric
for all other blades connected to the same PICMG 2.16 packet-switching bus within the chassis mid-plane.
The built-in Ethernet switch switches Ethernet traffic between the PICMG 2.16 bus, the 10/100 Ethernet
LAN port presented on the front panel of the front blade, and the two 10/100/1000 Ethernet WAN uplink
ports presented on the 6511RCrear panel of the rear blade. All three Ethernet ports provide access to the
SNMP agent and HTTP Web Management services within the 6511RC. In addition, all three Ethernet ports
provide access via the Internet Protocol to the other blades on the packet bus, including access to the Web
Management services residing within those blades. When combined with an external network management
system, the Ethernet switching feature on the 6511RC makes it possible to implement a packet-based network
management solution for all system elements connected to the same packet-switched bus in the ForeFront
chassis.

Management
Management Services
By providing a rich set of industry-standard management services accessible by a full menu of physical interfaces, the Model 6511RC offers an extensive selection of management options. The Matrix Switch provides the
following management services:
• HTTP Web-Management Interface accessible via any standard web browser
• SNMP version 1 configuration management (specified in RFC 1157)
• MIB II (specified in RFC 1213)
• Command Line Management Interface (CLI)
• SYSLOG Management Client (specified in RFC 3164)
• Out-of-Band RS-232 configuration port for management and control
• TELNET via Ethernet
• Remote Software Upgrade via FTP/TFTP
Management Interfaces
You can reach the Matrix Switch’s management services via any of the following physical interfaces:
• RS-232 Config Port presented as an RJ-45 connector on the front panel of the front blade
• PICMG 2.16 midplane connector block on the front blade
• 10/100 Ethernet port presented as an RJ-45 connector on the front panel of the front blade.
• Two 10/100/1000 Ethernet ports presented as RJ-45 connectors on the rear panel of the rear blade
Management Approach
Managing the Model 6511RC’s may be approached using one of two schemes, generally referred to as In-band
or Out-of-band management. In-band management refers to those schemes in which management information traverses the same network resources as network user traffic. Out-of-band management refers scenarios in
which management information does not traverse the same resources as network user traffic. In other words,
out-of-band management involves implementing a secondary, special-purpose, management network dedicated to carrying management information about the primary, user network. In-band management is more
efficient. However, because management information is susceptible to failures in the user network., it is less
reliable. Out-of-band management, while more reliable, is also more costly because it involves more equipment.
Management access paths into the Model 6511RC for both In-band and Out-of-band approaches are
described below.
• In-band management access paths include:
- The two RJ-45 10/100/1000 Ethernet trunk ports on the rear panel of the rear blade support in-band
management for applications where the Ethernet link is used as an aggregated trunk for user traffic as well
as a path for management information. An external management workstation communicates with the
management services in the Matrix Switch via a routed-protocol connection within the Ethernet link.
The management connection terminates at the management service within the Matrix Switch.
24 Hardware overview
Model 6511RC User Manual 1 • Introduction
- The PICMG 2.16 packet-switched bus (PSB). In order to manage the Matrix Switch in-band via the
PICMG 2.16 PSB, an external management workstation connects to the ForeFront chassis via another
ForeFront blade with management routing capability, such as the Model 6801RC EdgeRoute Network
Access Server or model 3096RC TDM Digital Access Concentrator, operating on the same bus. The
external management workstation communicates with the ForeFront system using either a Frame Relay
or PPP link within a DS0 or within an Ethernet link. The in-band management link terminates on the
module with management routing capability, which in turn communicates with the management services
in the Matrix Switch over the PICMG 2.16 PSB.
• Out-of-band management access paths include:
- The RS-232 config port on the front panel of the front blade
- The RJ-45 10/100 Ethernet LAN port on the front panel of the front blade
- The two RJ-45 10/100/1000 Ethernet LAN ports on the rear panel of the rear blade, in applications
where these Ethernet links are dedicated to management traffic.
Matrix Switch Interfaces
WAN Interfaces
The 6511RC provides connections to the following WAN interfaces:
• One SDH STM-1 uplink trunk port at 155.54 Mbps
-Physical SC or BNC connectors presented on the rear-blade rear panel
• Two Ethernet trunk ports at up to 1 Gbps
-Physical RJ-45 connectors presented on the rear-blade rear panel
The STM-1 WAN uplink port may be connected to an SDH network via the Optical SC ore electrical BNC
connectors presented on the rear blade.
Mid-Plane Interfaces
• Connection to the H.110 Time-Division Multiplexed bus providing 4096 DS0 channels of 64 kbps each
-Physical and electrical connections via the mid-plane connector block on the rear of the front blade
• Connection to the PICMG 2.16 Packet-Switched Bus (PSB)
-Physical and electrical connections via the mid-plane connector block on the rear of the front blade
LAN Interface
The 10/100-Mbps Ethernet LAN port is presented on an RJ-45 connector with an auto-sensing/full-duplex
10Base-T or 100Base-T interface. Also included are:
• 100Base-TX half-/full-duplex operation (100 + 100)
• 10Base-T half-/full-duplex operation (10 + 10)
• Auto detection and fallback
• 10/100 Mbps link and status indicators
Hardware overview 25
1 • Introduction Model 6511RC User Manual
RS-232 Config port
The RS-232 Config port provides access to the CLI management service. You will use the Config port to perform initial configuration of the Model 6511RC. The RS-232 port supports:
• Asynchronous data rates of 19.2 kbps, 8 data bits, no parity, 1 stop bit.
• An RJ-45 connector with EIA-561 pinouts
• A management interface that supports VT-100 terminals
• Hardware flow control (RTS and CTS)
Power system
The 6511RC obtains power from the CPCI chassis via PCMG 2.11 47-pin power connectors on the front and
rear blade. Total power consumption is a maximum of 43 Watts, provided by modular power supplies installed
in the cPCI chassis.
Central processing unit
The 6511RC employs an Intel i960VH RISC processor operating at 100 MHz/100 Mips. The CPU controls
the memory, front/back-panel and management interface for DS0 timeslot mapping, Ethernet switching, loopback and management services. System memory provided by:
• 4 MB Flash ROM
• 8 MB EDO DRAM
System timing
The system timing for the Matrix Switch must be configured using the blade’s management services, typically
via Web Management.
Clocking Mode
When configured in Master mode, the Matrix Switch serves as the Master clock source (timing reference) for
all other blades on the same H.100 bus within the Model 6476 chassis or Model 6676 chassis segment. When
configured in Backup mode, the Matrix Switch serves as an alternate Master clocking source (backup) should
the Master clocking source fail. When configured in Slave mode, the Matrix Switch will not provide system
timing over the H.100 bus for any other blades.
Clocking Source
Regardless of its clocking mode, the Matrix Switch can derive its own system timing from several sources. You
will define two clocking sources for the Matrix Switch, a first-choice (Primary Reference) and an alternate
(Fallback Reference). The Matrix switch will derive its own system timing from the Primary Reference as long
as it remains available. Should the Primary Reference become unavailable, the Matrix Switch will switch over
to the Fallback reference as the clock source for its own system timing. The following clocking sources can
serve as either the Primary Reference or Fallback Reference for the Matrix Switch:
• The internal oscillator (clock) residing on the Matrix Switch front blade
• A network clock recovered from the STM-1 SDH signal stream
• Another blade operating in either Primary or Secondary mode on the same bus.

Introduction
This chapter contains the following procedures for installing the Model 6511RC Matrix Switch:
Note
• “Unpacking the Model 6511RC Matrix Switch”—lists the contents in the Matrix Switch shipping con-
tainer
• “Matrix Switch hardware installation”—describes installing the Matrix Switch on a flat surface or in a stan-
dard 19-inch rack
• “Installing the network cables” on page 35—describes installing the power and network interface cables
• “Completing the hardware installation” on page 40—describes testing the Matrix Switch hardware to verify
that it is ready for software configuration
Before installing the Matrix Switch, you will need to obtain the line
type and encoding of the STM-1 link from your local telephone company (Telco).
Unpacking the Model 6511RC Matrix Switch
Inspect the shipping carton for external damage. Note any damage before removing the container contents.
Report equipment damage to the shipping carrier immediately for claim purposes. Save all packing materials in
case you need to return an item to the factory for servicing.
The Matrix Switch comes with the following items:
• The Model 6511RC Digital Cross-Connect (Matrix Switch)
• One RJ45-to-RJ45 cable for use with the console and Ethernet ports
• A DB9-RJ45 (EIA-561) adapter for connecting a PC's serial port to the Matrix Switch console port
Verifying that the ForeFront chassis is properly installed
You must verify that the ForeFront chassis is correctly installed before installing the Matrix Switch hardware
into the chassis. Check for the following:
• Correct electrical grounding—Improper chassis grounding may impair proper operation of the STM-1
electrical interface, thereby causing data transmission errors on the STM-1 link. See section “Verfying cor-
rect electrical grounding” on page 33 for directions on verify chassis grounding.
• Correctly installed front and rear panels over vacant chassis slots—Absent front or rear panels over vacant
module slots leaves the chassis interior open and thereby vulnerable to the following problems:
- Improper EMI shielding against both incoming and outgoing electromagnetic signals
- Impaired operation of the chassis cooling system, resulting in equipment overheating, including the SHD
laser subsystem on the Matrix Switch
See section “Verifying correct cover plate installation” on page 33 for directions on verifying proper cover
plate installation
32 Introduction
Model 6511RC User Manual 2 • Hardware installation
Verfying correct electrical grounding
Do the following to verify correct electrical grounding:
Improper chassis grounding may impair the operation of the
STM-1 electrical interface, thereby causing data transmission
errors on the STM-1 link.
1. Inspect the rack chassis grounding studs on the AC power module or DC power module (see figure 11 for
studs locations) to ensure a #12 AWG ground wire is attached.
Figure 11. AC power module and DC power module grounding studs locations
2. Inspect the remote end the #10 AWG ground wire and verify that it is attached to one of the following
grounding sources:
– The building ground rod (generally located at the site’s main service entrance)
– A sprinkler system pipe
– A cold-water pipe
– Building structural steel
Verifying correct cover plate installation
Missing front or rear panel cover plates leave the chassis interior open and vulnerable to the following problems:
• Impaired EMI shielding against incoming and outgoing electromagnetic signals
• Reduced chassis cooling system efficiency, which can resulting in equipment overheating, especially in the
SHD laser subsystem on the Matrix Switch
Do the following to verify that cover plates are properly installed:
1. Inspect the front of the chassis and verify that a cover plate is installed for each vacant module slot, and
verify that each cover plate’s fasteners are tightened securely to the front panel. Missing cover plates must
be replaced before installing the Matrix Switch.
Verifying that the ForeFront chassis is properly installed 33

Connecting the front-panel Ethernet LAN port
The Matrix Switch includes a 10/100Base-T transceiver, accessible via a physical interface on the front panel of
the front blade for connection to an Ethernet LAN. The Ethernet interface complies with IEEE 802.3 and is presented on a 6-pin RJ-45 female receptacle. Once connected to a LAN, the Ethernet port will autosense the speed
of the LAN and automatically negotiate half or full-duplex operation. This port provides access to the Matrix
Switch’s resident management services, including the HTTP/Web Management feature. This port also connects
to the on-board Ethernet Switch, thus providing Ethernet access to other blades within the ForeFront system via
the PICMG 2.16 PSB. This section describes connecting the Matrix Switch to the Ethernet LAN via an Ethernet
hub, switch, or workstation.
Connecting the 10/100Base-T Ethernet port to an Ethernet switch or hub
The 10/100Base-T Ethernet port (see figure 5) is designed to connect to an Ethernet switch or hub. The
Ethernet RJ-45 pin and signal definitions for the Matrix Switch or for a NIC card in a workstation/PC are
shown in figure 15. Connect a straight-through CAT-5 cable (one wired as shown in figure 15) between the
Matrix Switch and the hub/switch.
Figure 15. Ethernet RJ-45 pin and signal definitions for Matrix Switch
Connecting the 10/100Base-T Ethernet port to an Ethernet-capable workstation or PC
The 10/100Base-T Ethernet port can connect to a single Ethernet-capable workstation or PC by means of a
cross-over cable. Refer to figure 16 to assemble a cross-connect cable that will connect between the NIC Ethernet port in the workstation and the Matrix Switch 10/100Base-T Ethernet port.

Install the supplied RJ-45-to-RJ-45 cable with the DB9-RJ45 adapter between the Matrix Switch RS-232 port
(see figure 13 on page 35) and an open serial port on your computer. If you need to assemble your own cable,
refer to the pinout diagram in figure 17.
Figure 17. RJ-45 pin and signal definitions for Matrix Switch CONFIG port
Connecting the rear-panel STM-1 WAN port to an SDH network
The Matrix Switch offers two types of STM-1 interfaces—optical and electrical—presented on the rear panel of
the rear blade. Optical interfaces connect to fiber-optic network cables, while the electrical interfaces connect to
coaxial network cables. The rear-blade connectors must match the type of network cables and connectors used by
the SDH network to which you will connect.
Connecting the STM-1 optical interface to fiber-optic network cables
The following versions of the Matrix Switch rear blade offer an optical interface for the STM-1 port
• Model 6511RC/M155/SC20
• Model /EBNC6511RC/M155/SC20
The designation SC20 in the model code denotes that an optical interface conforming to ITU specification
G.957 and G.652 is present. The Matrix Switch presents the STM-1 optical interface on a pair of SC fiberoptic connectors, one for the transmiting (TX) and one for receiving (RX) signals (see figure 14 on page 35).
Note
The wavelength of the laser signal is 1310 nanometers. The singlemode fiber-optic cable connecting the STM-1 WAN port to the SDH
network must extend no farther than 12.4 miles (20 kilometers).
Installing the network cables 37

Figure 18. Fiber-optic SC cable connectors
Do the following to connect the dual singlemode fiber-optic cable (see figure 18) to the STM-1 SC connectors:
1. Remove the protective cap from the fiber optic cable connectors.
2. Attach the transmit fiber-optic cable connector to the TX SC connector on the rear blade (see figure 14 on
page 35).
3. Attach the receive fiber-optic cable connector to the RX SC connector on the rear blade.
Connecting the STM-1 electrical interface to coaxial network cables
The Matrix Switch presents the STM-1 electrical interface on a pair of 75-ohm female BNC connectors, one
for the transmiting (TX) and one for receiving (RX) signals (see figure 14 on page 35).
For most installations, the coaxial cable connecting the STM-1 WAN port to the SDH network can be no
longer than 325 feet (100 meters).
Note
The Matrix Switch electrical interface transmits a STM-1 signal with
an attenuation margin of 12.7dB at 78 MHz over coaxial cable. The
12.7dB attenuation margin typically results in a transmission distance
limitation of approximately 360 feet (110 meters) for RG-59U
coaxial cable.

Figure 19. BNC coaxial cable connectors
Do the following to connect the dual 75-ohm coaxial cable (see figure 19) to the STM-1 BNC connectors:
1. Attach the transmit connector of the coaxial cable to the TX connector on the rear blade (see figure 14 on
page 35).
2. Attach the transmit connector of the coaxial cable to the RX connector on the rear blade.
Connecting the rear-panel Ethernet WAN/management ports
The Matrix Switch provides two 10/100/1000Base-T Ethernet transceivers, accessible via physical interfaces
on the rear-panel of the rear blade, for connection to an external router, hub, or switch. Both interfaces are presented on RJ-45 6-pin female receptacles. The interfaces comply with IEEE specification 802.3 and are labeled
ENET 1 and ENET 2 (see figure 14 on page 35).
Once connected to a LAN, the Ethernet port will autosense the speed of the LAN and automatically negotiate
half or full-duplex operation. The ports provide access to the Matrix Switch’s resident management services,
including the HTTP/web management feature. This port also connects to the on-board Ethernet switch, thus
providing Ethernet access to other blades within the ForeFront system via the PICMG 2.16 PSB.
You can use the two high-speed Ethernet ports to implement the following functions:
• Ethernet trunks. You can connect the 10/100/100 Ethernet ports to a WAN router in order to deliver
high-speed aggregated packet-based traffic to and from the ForeFront system over packet-switched WAN
trunks. The WAN router would then be connected to a private WAN or to the Internet.
• Ethernet management network. You can connect the 10/100/100 Ethernet ports to a local area network
via an external hub or switch in order to implement an out-of-band management network. To create an
external management network, all ForeFront blades must connect to the management LAN via an Ethernet
port residing on each blade. The Matrix Switch also offers access to an internal management network, the
PICMG 2.16 PSB. By means of its on-board Ethernet switch, the Matrix Switch provides a packet-switched
path to all blades operating on the same PICMG 2.16 bus, which a Network Management System can use
to communicate with the management services on those blades.

The 10/100/100Base-T Ethernet ports may be connected to a WAN router, or to an Ethernet hub or switch.
To connect the router, hub or switch to the Matrix Switch, you must use a straight-through CAT-5 RJ-45
cable (one wired as shown in figure 15 on page 36). Figure 15 shows the Ethernet RJ-45 pin and signal defi-
nitions for the Matrix Switch. For cable distance limitations please consult the IEEE specification 802.3.
To connect the 10/100/100 Base-T Ethernet port to a router, hub or switch:
1. Connect the RJ-45 connector at one end of the cable into the 6-pin RJ-45 receptacle on the rear-panel of
the 6511RC rear-blade.
2. Connect the RJ-45 connector at other end of the cable into the 6-pin RJ-45 receptacle on the router, hub,
or switch.
Completing the hardware installation
This section verifies that the Matrix Switch hardware is operational to the point where you can begin configuring the software settings.
Power is delivered from the CPCI chassis backplane through the 47-pin PICMG 2.11 power connectors on
the 6511RC blades. Upon insertion into the CPCI chassis, the Model 6511RC immediately powers up and
begins its boot cycle. During the boot cycle the following should occur:
1. The POWER LED illuminates, indicating normal power is being applied to the 6511RC.
2. The green SYSTEM LED begins flashing, indicating the 6511RC is operating normally.
Hardware installation is now complete. To configure the 6511RC for operation, refer to chapter 3, “Configur-

Figure 29. Operator Actions buttons
From the
Home
page, the following actions can be performed:
• Record Current Configuration—clicking on this button (see figure 29) saves the current configuration
from volatile DRAM memory to FLASH memory. Once the configuration is saved into FLASH memory,
the configuration will not be lost even if the power is cycled on the 6511RC. Initially, changes made to the
6511RC configuration are stored in volatile DRAM, enabling the user to set the box up with a working
configuration before committing it to storage in FLASH. When you select Record Current Configuration,
the 6511RC stores your changes to FLASH memory.
Note
If you want to save the configuration changes that you have made,
you must click on
Record Current Configuration
, otherwise all configuration changes will be lost if the power to the Model 6511RC is
turned off.
• Hard Reset—this button (see figure 29) causes the Model 6511RC to perform a cold restart. When you
select Hard Reset, the Matrix Switch confirms that you want to execute this command. Then, the Matrix
Switch will disconnect all current sessions, re-initialize the interfaces, and re-load configuration parameters
from FLASH.
• Set Factory Default Configuration—this button (see figure 29) clears out the configuration in FLASH and
loads the factory default parameters into FLASH memory. The factory default settings will not execute on
the Model 6511RC until it is re-booted by doing a Hard Reset.
Note
Set Factory Default Configuration (figure 29) will delete the Model
6511RC’s Ethernet IP address, any routing information, and any
other site-specific configuration changes made for your particular
installation. You will have to re-enter the Model 6511RC’s Ethernet
IP address and netmask using the front-panel control port in order to
gain access the HTTP/HTML Management pages again.

Configuring the default gateway
The default gateway IP address, if defined, is used solely for managing the 6511RC remotely via the Ethernet
port. The 6511RC does not transmit or receive user data nor any other traffic via the default gateway IP
address or the Ethernet port.
Do the following to add the default gateway:
1. On the 6511RC Configuration Menu (see figure 27 on page 48), click the IP hyperlink to open the IP
Overview page (see figure 30).

3. The Defined Routes table (see figure 32) will contain exactly one route, displayed in the first row of the
table. The 6511RC created this route automatically when you defined the Ethernet IP address during Ini-
tial Configuration, earlier in this chapter. That first row displays the route and netmask for the primary IP
address you defined for the Matrix Switch Ethernet interfaces.
Figure 32. Defined Routes table
4. You will use the first row in the
Define a New Route
table (see figure 33) to define the default gateway. The
Destination field contains the value 0.0.0.0. Because the netmask for the default gateway is implied by the
Matrix Switch’s primary IP address, the Mask field does not display. In the Gateway field, enter your
6511RC’s default gateway IP address.
Figure 33. Define a New Route table
5. Click the Define button (see figure 33) to activate the new default gateway address.
Configuring the system clocking parameters
In this section you will define the system clocking configuration for the Matrix Switch. Three issues pertain to
system clocking:
• Module clocking mode—Will this Matrix Switch serve as a Master timing source for the other modules on
the H.110 bus? (See section “Module clocking mode” for details.)
• Module clocking source—What clock pulse will the Matrix Switch use for primary reference and alternate
(fallback) reference. (See section “Module clocking source and fallback” on page 53 for details.)
• Module clocking fallback—Will you enable or disable the clocking fallback feature in case the primary ref-
erence fails? (See section “Module clocking source and fallback” on page 53 for details.)
Module clocking mode
Module clocking mode defines what role the Matrix Switch will assume on the H.110 bus with respect to system timing. You can select master(1), secondary(2), or slave(3) for the value of Clocking Mode. The master will
drive the main reference clock for the chassis. Should the master fail, the secondary will drive the main refer-
52 Using a browser to complete Model 6511RC configuration
Model 6511RC User Manual 3 • Configuring the Matrix Switch for operation
ence. Slaves will not drive any clock reference. Most often the 6511RC will be defined as the master(1), while
most other modules in the chassis will be defined as slave(3).
Module clocking source and fallback
There are two module clocking source parameters, the primary reference and the fallback reference. Unless it fails
or becomes disconnected, the primary reference provides the system clock for the 6511RC. Should this failure
occur, the fallback reference will become the clocking source for the 6511RC’s system clock.You must choose
one of the following values as the clocking source for each reference:
• An internal oscillator
• The STM-1 port
• The system clock provided by the H.110 clocking master, (i.e. another module in the chassis).
The following examples illustrate how to define the system clocking parameters for two scenarios.
Example 1. In this example, your 6511RC will be the clocking master for all other modules on the same
H.110 bus. Your 6511RC will derive its own timing from its STM-1 port as the main reference,
internal oscillator as the fallback reference
.
To define the system clocking parameters:
and from its
1. Connect a STM-1 WAN line to the 6511RC’s STM-1 port.
2. Click the System Clocking hyperlink on the 6511RC Configuration Menu (see figure 27 on page 48) to open
the System Clocking Overview page (see figure 34).

Configuring the SDH circuit parameters
In order for the STM-1 link to function correctly, you must correctly define the values of certain configurable
parameters that affect the SDH circuit. In order to configure the STM-1 link, you must first gather the following information:
• Which E1 mapping path—either AU3 or AU4—will be used within the STM-1 link
• Section trace message length
• The value of the JO byte for section trace messages
• Path-1 trace message length
• The value of the J1 byte for path-1 trace messages
• The value of path-1 signal label
• The E1 payload type, either asynchronous or byte synchronous

Configuring the SDH physical interface type
Do the following to define the physical interface type providing the STM-1 link:
1. In the SDH Physical Configuration section (see figure 38), select from the Physical Interface drop-down
menu the value that corresponds to the physical cabling attached to your STM-1 interface ports. If you are
using fiber-optic cable connected to the rear-card SC connectors, then select optical(0). If you are using
coaxial cables connected to the rear-card BNC connectors, then select electrical(1).

2. Click the
Submit
button to activate your selection.
Configuring the SDH interface parameters
1. In the SDH Interface Configuration section (see figure 39), for Circuit Identifier, enter an optional alphanu-
meric name for this STM-1 link.
Figure 39. SDH Interface Configuration section
2. If section trace is enabled in your connected SDH network, go to step 3. Otherwise, because section
trace is disabled, for the Section Trace Monitor parameter, select sectionTraceDisable(0) from the dropdown menu, then go to step 7 to define the value of the SDH Payload Mapping parameter.
3. Because section trace is enabled in your connected SDH network, for the Section Trace Monitor parame-
ter, select sectionTraceEnable(1) from the drop-down menu.
4. For the Section Trace message string, enter the alphanumeric string your connected SDH network uses for
the section trace message string in the SDH frame.
Note
The Section Trace parameter only applies with 16-byte and 64-byte
section trace messages. For 1-byte trace messages, the J0 byte parame-
56 Using a browser to complete Model 6511RC configuration
Model 6511RC User Manual 3 • Configuring the Matrix Switch for operation
ter applies. When the section trace message length is defined to be
one byte, the Matrix Switch will ignore the value of Section Trace.
5. For Section Trace Msg Len, from the drop-down menu, select the value used by the SDH network your
Matrix Switch is connected to: either 1, 16, or 64-byte trace messages.
6. For Section Trace J0 Byte enter the value your connected SDH network uses for the J0 byte in the SDH
frame.
Note
J0 applies only with 1-byte Section Trace Messages. For 16-byte and
64-byte trace messages, the trace message string applies and the value of
J0 is ignored.
7. For SDH Payload Mapping, select the payload type corresponding to the way your connected SDH net-
work maps the E1 payload into the SDH frame structure. Asynchronous E1 payload mapping is most
common, so the factory default value on the Matrix Switch is stm1MappedAsynchE1(0). If your connected
SDH network performs byte-synchronous E1 payload mapping, then select stm1MappedBytesynchE1(1)
from the drop-down menu.
8. For Tx Payload Scramble, if your SDH network expects to receive a scrambled payload select SDHScram-
bleEnable(1) from the drop-down menu, otherwise select sdhScrambleDisable(0).
9. For Rx Payload Scramble, if your SDH network transmits a scrambled payload select SDHScrambleEn-
able(1) from the drop-down menu, otherwise select sdhScrambleDisable(0).
10. For SDH Mapping, select the type of AU corresponding to the SDH multiplexing path you desire. To
multiplex seven TUG-2s into an AU-3, select au3Mapper(0) (the factory default) from the drop-down
menu. To multiplex three TUG-3s into an AU-4, select au4Mapper(1).
11. Click the Modify button to save your work into operating memory (volatile DRAM) and activate the new
parameter values.
Configuring the SDH path trace parameters
If you selected AU-4 mapping in the preceding procedure, the Matrix Switch will display one set of five parameters pertaining to Path 1. If you selected AU-3 mapping, the Matrix Switch will display three sets of five parameters each pertaining to Paths 1, 2, and 3. Do the following to define the values for the SDH path trace parameters:
1. If path trace is enabled in your connected SDH network, go to step 2. Otherwise, because path trace is
disabled, in the SDH trace parameters table (see figure 40), for Path-1 Trace Monitor, select pathTraceDis-
able(0) from the drop-down menu. Refer to section “Configuring DS0 idle codes” on page 58.
Figure 40. SDH Path Trace parameters
Using a browser to complete Model 6511RC configuration 57
3 • Configuring the Matrix Switch for operation Model 6511RC User Manual
2. Because path trace is enabled in your connected SDH network, in the SDH trace parameters table (see
figure 40 on page 57), for Path-1 Trace Monitor, select pathTraceEnable(1) from the drop-down menu.
3. For Path-1 Trace message, enter the alphanumeric string your connected SDH network uses for the path-1
trace message in the text box.
Note
The Path-1 Trace message parameter only applies with 16-byte and
64-byte section trace messages. For 1-byte path trace messages, the J1
byte parameter applies. When trace message length is defined to be
one byte, the Matrix Switch will ignore the value of Path-1 Trace.
4. For Path-1 Trace Msg Len, select the value corresponding to the trace message length your connected SDH
network uses.
5. For Path-1 Trace J1 Byte, enter the value your connected SDH network uses for the J1 byte in the
SDH frame.
Note
J1 applies only with 1-byte path trace messages. For 16-byte and 64byte trace messages, the trace message string is used and the value of
J1 is ignored.
6. For Path-1 Signal Label, enter the value your connected SDH network uses for the path-1 signal label in
the SDH frame.
7. If you have selected AU-3 mapping, repeat steps 1 through 6 to define values for the path-2 and path-3
trace parameters.
8. Click the Modify button to save your work into operating memory (volatile DRAM) and activate the new
parameter values.
Configuring DS0 idle codes
If you want your Matrix Switch to encode vacant DS0 channels with the standard E1 idle code (the hexadecimal value 7E), you must follow the procedures below to designate which DS0 channels within the STM-1 signal stream should be so encoded. Obviously, in order to correctly define the idle code configuration, you must
know which DS0 channels in the SDH frame are expected to be idle. Defining the idle code configuration
involves two steps: you must first access the DS0 Idle Code Configuration web management page, then use that
page to select the idle DS0 channels from the STM-1 structure and designate them as idle.

Figure 41. E1 Link page
2. To view all of the 63 E1s within the STM-1 link, first ensure that:
– tug3ALL(0) is selected next to the label TUG3
– tug2ALL(0) is selected next to the label TUG2
then click the Submit Query button to display the next page showing E1 link status (see figure 42).
Figure 42. Page showing E1 link status
This page displays all 63 E1 links according to their position within the STM-1 mapping structure: each
E1 resides within a tributary unit (TU), 3 TUs reside within each level-2 tributary unit group (TUG-2).
The final level of multiplexing concentrates 7 TUG-2s within either a level-3 administrative unit group
(AUG-3), or a level-3 tributary unit group (TUG-3). The TUG-3 then resides within a level-4 administrative unit group (AUG-4).

3. To access the DS0 Idle Code Configuration page for a selected E1, scroll right to view the DS0 configura-
tion column, then click the blue diamond icon to display the SDH DS0 Idle Code Detail page (see
figure 43).
Figure 43. SDH DS0 Idle Code Detail page
Defining the DS0 idle code configuration
The SDH DS0 Idle Code Detail page (see figure 43) displays a table for a selected E1, specified by the page title,
within the STM-1 link. The table displays the value of the idle code parameter for each of the 32 DS0s within
the specified E1 stream. To define the idle code configuration for the selected E1:
1. Find the DS0 number for which you want the Matrix Switch to generate an idle code.
2. Select the value enable(1) from the adjacent drop-down menu.
3. Repeat steps 1 and 2 for each DS0 for which you want to enable idle code generation.
4. Click the Modify button to save your work into operating memory (volatile DRAM) and activate your
changes.
To complete the DS0 idle code configuration for the entire STM-1 link, you will ned to repeat the above procedures for each E1 that you want to enable DS0 idle code generation for.
Selecting the SDH mapping path
The Matrix Switch offers two options for the SDH mapping path: you can select the mapping path terminating with TUG-2 and AU-3 or TUG-3 and AU-4.

3. Scroll down to the SDH mapping parameter and select the appropriate mapping path from the drop-down
menu. Select au3Mapper(0) or au4Mapper(1). To multiplex seven TUG-2s into an AU-3, select
au3Mapper(0) (the factory default) from the drop-down menu. To multiplex three TUG-3s into an AU-4,
select au4Mapper(1).
4. Click the Submit button to save changes.
You are now ready to define DS0 mappings.
Defining DS0 mappings
In order for the STM-1 link to carry traffic through the Matrix Switch to and from the ForeFront system, you
must define a set of DS0 mappings (correlations). You will define mappings between the full-duplex DS0s
within the STM-1 link and the simplex DS0s within the H.110 bus. While it is not necessary to define a mapping for every DS0 in the SDH link, only the mapped DS0s will carry user data. Unmapped DS0s may be configured to carry an idle code. Otherwise, unmapped DS0s will carry a random bit stream.
For each DS0
Mapping
you define, you will create a correlation between a communications channel in the
STM-1 link and a communications channel within the ForeFront chassis mid-plane. Each STM-1 channel
consists of a set of full-duplex DS0s. Each midplane channel consists of two simplex sub-channels, transmitted
and received. Each sub-channel consists of a set of simplex DS0s. You will define each STM-1 channel and
each mid-plane sub-channel by specifying one or more timeslot numbers up to a maximum of 32 timeslots per
channel. For a STM-1channel you will select up to 32 timeslot numbers from the range numbered 1 to 32. For
a mid-plane channel you will select up to 32 timeslots from the range numbered 1 to 128.
On the STM-1 side, there are 63 E1 signal streams, each comprising 32 DS0s. Within an E1, each DS0 is a
full-duplex channel, comprising a transmitted and a received signal stream. The STM-1 link comprises 2016
full-duplex DS0s.
On the mid-plane side, there are 4096 simplex DS0s within the H.110 bus, organized into 32 ports. Each
H.110 port comprises 128 DS0s. Within the H.110 bus, each DS0 is a simplex signal stream, which the
H.110 bus can either transmit or receive. You will define the direction of a mid-plane DS0 during the mapping
process as either transmitting to the H.110 bus or receiving from the H.110 bus. The H.110 bus provides
4096 simplex DS0s.
When entering E1 and H.110 timeslot numbers, you must define the same number of timeslots on the SDH
and mid-plane sides of the mapping. The timeslots are defined by entering a text string that represents the
timeslot numbers.
The following notation should be used for assigning timeslots:
• dash: (-), e.g., 1-4
• comma: (,), e.g., 1,4,9
• combo: 1-2,3,6-7
62 Using a browser to complete Model 6511RC configuration
Model 6511RC User Manual 3 • Configuring the Matrix Switch for operation
The Matrix Switch offers two formats for defining DS0 mappings:
• E1 port format—You will identify the 63 E1 signal streams within the STM-1 link using E1 port numbers
1-63. Those with little to moderate experience working with SDH network architecture will most likely
find E1 format to be the simplest and most straightforward method for defining DS0 mappings. Refer to
section “Defining DS0 mappings using E1 port format” on page 64.
• TU format—You will identify an E1 signal stream according to its location within the STM-1 hierarchy,
using the TU-12 number and TUG-2 number within an AUG-3 or within a TUG-3/AUG-4. Experienced
SDH engineers with a clear understanding of STM-1 architecture will most likely prefer to use TU format
to define DS0 mappings. Refer to section “Defining DS0 mappings using TU format” on page 69.

Matrix Switch test tools
For the purpose of testing and troubleshooting the STM-1 link, the DS0 Mapping definitions, and H.110 bus
connectivity, the Model 6511RC Matrix Switch offers the following tool sets:
• Loopback test modes for the Matrix Switch STM-1 port
• SDH Section Trace and SDH Path Trace functions for the STM-1 link
The following sections describe these tool sets in detail.
Loopback test modes for the STM-1 port
The Matrix Switch provides the following diagnostic loopback test modes for the STM-1 port:
• SDH facility loop (see section “Facility Loop [sonetFacilityLoop(1)]” on page 87)
• SDH terminal loop (see section “Terminal loop [sonetTerminalLoop(2)]” on page 88)
• H.110 loop (see section “Other Loop [sonetOtherLoop(3)]” on page 90)
The facility and terminal loops are specified by the SDH protocol. The H.110 loop is proprietary to the ForeFront Matrix Switch, and fulfills the SDH specification for a third vendor-defined loop.
86 Matrix Switch test tools
Model 6511RC User Manual 5 • Troubleshooting and maintenance
To understand how these test modes work, you must first understand the basic architecture of the Model
6511RC’s TDM mapping functions. The TDM mapping function provides the connection between the
STM-1 port and the H.110 bus. Within the TDM mapper (see figure 60) data passes between the SDH fram-
ing processor and the H.110 framing processor.

The various loopback test modes route data through one or both of these framing processors, with the data
path making a U-turn in one framer or the other. Subsequent paragraphs describe the details of each loopback
test mode for the STM-1 port.
Facility Loop [sonetFacilityLoop(1)]
You can use the facility loop to test and troubleshoot the operation of the STM-1 link, including the Matrix
Switch’s STM-1 port and the fiber-optic or coaxial cables connected to it.
The facility loop (see figure 61) returns data received from the SDH facility (the STM-1 link) back to the same
SDH facility. In other words, when the Facility Loop is activated, the Matrix Switch receives data from the
STM-1 link and transmits the (unmodified) data back to the STM-1 link.
The U-turn for the facility loop occurs within the SDH framer on the Matrix Switch. The data path for the
facility loop traverses the SDH framer, but not the H.110 framer. Data enters the Matrix Switch at the STM-1
receive port, and enters the SDH framer where it loops back toward the STM-1 link, leaving the Matrix switch
at the STM-1 transmit port.

Terminal loop [sonetTerminalLoop(2)]
The terminal loop (see figure 63) returns data received from the SDH terminals back to those SDH terminals
(other ForeFront modules on the same H.110 bus). In other words, when the Terminal Loop is activated, the
Matrix Switch receives data from other ForeFront modules via the H.110 bus and transmits the (unmodified)
data back to those same modules (via the H.110 bus).
The U-turn for the terminal loop occurs within the SDH framer on the Matrix Switch. The data path for the
terminal loop traverses both the H.110 framer and the SDH framer. Data transmitted by the SDH terminals
(other ForeFront modules) enters the Matrix Switch from the H.110 bus through the mid-plane
Figure 63. Terminal loopback test mode
88 Matrix Switch test tools
Model 6511RC User Manual 5 • Troubleshooting and maintenance
connections. The data passes through the H.110 framer, then traverses the SDH framer where it loops back,
passing through the H.110 framer again. The data leaves the Matrix switch through its mid-plane connections
and returns via the H.110 bus to the sending SDH terminals (other ForeFront modules).
The terminal loop affects only those DS0s that are mapped from the H.110 bus to the STM-1 link or from the
STM-1 link to the H.110 bus. Likewise, the loop affects only those ForeFront modules included in one or
more such DS0 mappings.
The terminal loop exercises the physical and logical connections between the Matrix Switch and the other
ForeFront modules connected to the same H.110 bus (its SDH terminals). You can use the terminal loop to
test and troubleshoot the DS0 mappings you have defined while simultaneously testing H.110 bus connectivity with other ForeFront modules via the chassis mid-plane.
To activate the Terminal Loop test mode:
1. On the configuration menu, click the SDH hyperlink to display the SDH Overview page.
2. At the top of the SDH Overview page, click the Configuration hyperlink to display the SDH Configuration
page (see figure 64).

Other Loop [sonetOtherLoop(3)]
The other loop [sonetOtherLoop(3)] operates much like the facility loop, however the data enters the H.110
framer where it makes a U-turn. The Other Loop test mode (See figure 65) is a factory debugging and hardware
test tool intended for use by Patton engineering. The terminal loop and facility loop provide all the functionality a Matrix Switch operator should require. Though it is available to Matrix Switch operators, the Other Loop
test mode offers no further advantage for testing or troubleshooting in the field.
Figure 65. Other Loopback test mode
SDH section trace and path trace
The Matrix Switch supports the section trace and path trace functions specified in the SDH protocol. You can
use these trace functions to verify connectivity across an SDH circuit or circuit segment and to validate the link
is operating properly. When a trace is enabled, two SDH devices pass a trace message to each other across an
SDH link or link segment. When the message arrives without errors the trace succeeds, indicating the connection is healthy. If a device receives a trace message that does not match the expected value, a trace mismatch
occurs, indicating an error in the connection.
Note
The trace function must be enabled and configured identically in
both the Matrix Switch and the connected SDH network in order for
the trace to operate.

Sections and paths
Between a pair of SDH multiplexers, an SDH circuit may comprise multiple cable segments connected by
intermediate devices such as signal repeaters and add-drop multiplexers (see figure 66). A cable segment with a
regenerator at one or both endpoints is called a section. A set of cable segments with an add-drop multiplexer at
one or both endpoints is called a line. An SDH circuit with full-service multiplexers at both endpoints is called
a path.
Figure 66. Section, path, and line within an SDH circuit
Section trace
The section trace function verifies section connectivity between the two section-terminating nodes.Two SDH
section-terminating devices perform the section trace over the STM-1 media segment between them. When
section trace is enabled, the SDH frame carries a trace message in either the J0 byte or the section trace string.
The value you define for Section Trace Message Length determines which field will carry the Section Trace Message, as specified below:
• 1-byte section trace message length
tion trace string. The value of J0 may be any positive integer in the range of
—
Use the J0 byte for trace messaging, and ignore the contents of sec-
0 to 255.
• 16-byte section trace message length—Use the section trace string for section trace messaging, and ignore
the contents of J0. The value of section trace string may be any alphanumeric text string up to 15 characters
long. The 16-byte field includes CRC-7 in the 16th byte.
—
• 64-byte section trace message length
Use the section trace string for section trace messaging, and ignore
the contents of J0. The value of section trace string may be any alphanumeric text string up to 64 characters
long. The 64-byte section trace string does not include any CRC.
To enable section trace:
1. On the configuration menu, click the SDH hyperlink to display the SDH Overview page.

The 64-byte field does not include any CRC.
Number of paths per frame
The STM-1 frame can support one path or three paths, depending on how the STM-1 signal is mapped.
• AU-4 mapping
—
Using AU-4 mapping the STM-1 frame supports a single path. When you select AU-4
mapping for the value of the SDH Mapping parameter, the Matrix Switch displays only the Path-1 Trace
parameters.
—
• AU-3 mapping
Using AU-3 mapping the STM-1 frame supports three paths. Each of the three AU-3s in
the STM-1 frame represents a separate path. When you select AU-3 mapping for the value of the SDH Map-
ping parameter, the Matrix Switch displays the path trace parameters for each of the three paths. Path-1,

as described in the follow section.
Exporting the current Model 6511RC configuration
The 6511RC Matrix Switch provides Import/Export functions. These functions enable you to back up (export)
and restore (import) your Matrix Switch’s configuration parameters against possible failure. Should your
Matrix Switch ever need replacing, a previously saved copy of your (exported) configuration file can quickly be
loaded (imported) into a replacement Matrix Switch.
Note
Import/Export functions require superuser access privileges.
