Campus units have a default HDSL configuration to operate in Standard
Mode with a T1 (1.544 Mbps) HDSL Rate. This default configuration is
compatible with other Campus-RS and Campus-HRS products (including the
Campus-T1 desktop units and line units) if you choose to operate them in
their default configuration.

You can also configure the HDSL parameters through the LCD menus.
See “Using the LCD for Configuration and Management” on page 7-97
for instructions on using the LCD panel. To view system performance and
other status information, see “Monitoring and Testing the Campus System”
on page 5-73.
Changes to the HDSL operating mode or transmission rate are
not automatically made to the remote unit. These changes
must be made at both the local and remote units for the HDSL
link to be re-established. If the remote unit is not easily
accessible, you can follow the instructions in “Logging On a
Remote Campus Unit” on page 1-15 to use a PC for a remote
logon (if an HDSL link is up) and make the preferred change.
When you change the HDSL settings on the remote unit, the
HDSL link is lost; it is re-established when you make the
identical change(s) on the local unit.

Chapter 2 - Configuring HDSL Parameters
Selecting HDSL Parameters
You can use the default HDSL setting for your Campus-RS unit (when also
using the default settings on the remote unit to which this unit connects)
which are:
•
standard for the HDSL operating mode
•
auto for the transceiver mode (determines which device is the master
or slave)
•
T1 for the HDSL rate
If you want to change any of these parameters, select one of the following
sections based on the HDSL operating mode you will use. Campus-RS offers
these two HDSL operating modes:
•
•
Standard mode (page 22) provides compatibility between a Campus-RS
product and an earlier Campus product (legacy Campus) that has a
HDSL interface including T1, E1, or 768:
–
for T1, the maximum transmission rate is 1.544 Mbps over 2 pairs
–
for E1, the maximum transmission rate is 2.048 Mbps over 2 pairs
–
for 768, the transmission rate is 768 kbps over 1 pair
Extended mode (page 23) provides a fractional rate selection between the
HDSL interfaces of two Campus-RS products. The rate is selectable as
follows:
–
for 1 pair in 64 kbps increments, starting at 128 kbps up to
2.304 Mbps
–
for 2 pair in 128 kbps increments, starting at 256 kbps up to
4.608 Mbps

The Campus-REX2 RS is a 10/100Base-T Ethernet interface card that
provides connectivity for LAN services. The Campus-REX2, as its default
configuration, provides IEEE 802.1d transparent MAC level bridging.
You can change the default configuration to routing and set the appropriate
IP parameters for the LINE and LAN. Also, you can set up parameters for
SNMP management.
You can use the Campus-REX2 with its default settings that include bridge
mode, cHDLC encapsulation, and Spanning Tree protocol set to disabled. If,
however, you require to change any of these parameters for implementing
your network, use the procedures in this chapter.

Select a timing
•
Internal (default setting) which takes its timing from an internal
oscillator
•

The Timing Source option determines the source of circuit timing on the
HDSL link. The proper setting of the Timing Source option depends
upon the interface card of the remote Campus unit:
•
If the Campus-REX2 is connected to a Campus unit with another
Campus-REX2, leave the Timing Source option set to Internal. Set
the other end (remote) of the connection to HDSL; the Campus
system will not operate properly if both units are set to HDSL.
•
If the Campus-REX2 is connected to a Campus unit with a
synchronous interface card, such as a Fractional V.35 card, the
timing source depends on the setting of the Primary Timing Source
option of the remote unit:
–
Set the Timing Source to HDSL if the remote unit is set to
Internal or Data Port.
–
Set the Timing Source to Internal if the remote unit is set to
HDSL.
See the Campus-RS Fractional Interface Card User Manual for
information on the Primary Timing Source option.
•
If the Campus-REX2 is connected to a Campus unit with a Campus
CSU/DS-1 or CSU/DSX-1 interface card, set the Timing Source
option to Internal.

•
If the Campus-REX2 is connected to a Campus unit with a
synchronous interface card, such as a Fractional V.35 card, the
timing source depends on the setting of the Primary Timing Source
option of the remote unit:
–
Set the Timing Source to HDSL if the remote unit is set to
Internal or Data Port.
–
Set the Timing Source to Internal if the remote unit is set to
HDSL.
See the Campus-RS Fractional Interface Card User Manual for
information on the Primary Timing Source option.
•
If the Campus-REX2 is connected to a Campus unit with a Campus
CSU/DS-1 or CSU/DSX-1 interface card, set the Timing Source
option to Internal.

Configuring and Deleting Static IP Routes
Static IP routes define a fixed and manually configured path for data sent by
the Campus-REX2 to a destination host. This table contains a maximum of
32 explicit routes. Each route comprises a destination network, subnet mask,
and hop count.
You can add static routes by selecting either:
•
Add Static Route as described in this section
•
Static Route Table (see “Managing the Static Routing Table” on
page 57) and using the (A)dd route command
When you enter a static IP address that is a specific host interface, you must
enter 255.255.255.255 as the subnet mask to include that specific host
interface in the static routing table.
You can also configure the default gateway in the static routing table by
entering a destination IP address of 0.0.0.0 with a subnet mask of 0.0.0.0 and
then entering the IP address for the default gateway.

MANAGEMENT
SNMP protocol provides a way for HP OpenView or an Element
Management System (EMS) such as StarGazer to manage the Campus-REX2
system over a network. A Campus-RS Management Unit (CMU), installed
into a Campus-Star chassis, provides SNMP management for components in
the chassis and for management of elements attached to the chassis (desktop
units or units in other Campus-Star chassis). The EMS can directly manage a
Campus-REX2 that is in a desktop unit or a Campus-Star chassis.
You can also set the Campus-REX2 to perform authentication error trap
generation. To enable this feature, do the following:
•
Set the Authentication Trap Status to Enabled or Disabled.
•
Enter an IP Address for each Trap Receiver.
•
Enter a community string for each Trap Receiver.

Chapter 5 - Monitoring and Testing the Campus System
Performing Loopback Testing
Loopbacks provide testing for the HDSL data communication path between
the Campus unit, the remote unit, and the remote host equipment. Loopback
tests can be run only when one end of the HDSL connection (either the local
or the remote) is a Campus-REX2 or Campus-REX (both ends cannot be
Campus-REX2 or Campus-REX).
The following section describes how to set up, run, and terminate
loopback tests.
Configuring Loopbacks
If both the local and remote Campus units have a
Campus-REX2 RS Interface Card, no loopbacks are
supported between the two units.
The Campus-REX2 supports the following types of loopbacks between a
Campus-REX2 and another Campus unit that contains a synchronous
interface card such as V.35 or DSX-1:
•
The Remote to Remote loopback tests the remote data port.
•
The Local to Remote loopback tests the remote data port, the entire data
path inside the remote Campus unit, the HDSL line, the HDSL
transceivers of both units, and most of the internal data path inside the
local unit. This loopback does not test the local data port drivers and
receivers.
Once a loopback condition has been initiated, it remains in effect until it is
cleared. You may also set a loopback timeout to clear the loopback
automatically after a set period of time has elapsed.

UPGRADING CAMPUS UNIT SOFTWARE
This section describes how to upgrade the software on your Campus-REX2.
To upgrade, you will use FTP on your Windows- or Unix/Linux-based PC to
transfer the new software to the Campus-REX2. A file containing the new
software is supplied with the name carex2_Vx.y.tar, where x.y is the software
release version. When you upgrade software, the configured parameters for
HDSL, system, and REX2 are not affect by the upgrade.
Prior to updating software, ensure the following has been completed:
•
The Campus-REX2 is configured with a LAN IP address (see
“Configuring the REX2” on page 29.)
•
You can successfully 'ping' the configured LAN IP address of the
Campus-REX2.
•
You have access to the file containing the upgrade software
(carex2_Vx.y.tar) from the PC that you used to perform the 'ping'.
Do not remove power to the Campus unit or disconnect the
Line and LAN side network connections when upgrading
software or saving configuration.

FTP commands below. For example:
c:\> cd \campus\rex2\upgrade\v5.1
3
Copy the upgrade software file (carex2_Vx.y.tar) to this directory.
4
At the DOS prompt, start FTP using the configured LAN IP address of
the Campus-REX2. For example:
c:\campus\rex2\upgrade\v5.1> ftp 192.168.1.1
A message indicating successful connection to the LAN IP address
follows. If this does not occur, verify that you have correctly entered the
LAN IP address
5
FTP then prompts for a user name and password to connect FTP to the
Campus-REX2. For example:
User (192.168.1.1:(none)): admin
Password: admin (or previously configured REX2 password; see
“Setting a Password” on page 69)
When FTP is successfully connected to the Campus-REX2, FTP displays

RECOVERING SOFTWARE
This recovery process returns the Campus-REX2 to a working state after a
file system failure. If, upon bootup of the Campus-REX2, it is determined that
the file system is corrupted, the unit performs the process described below.
The potential for file system failure occurs if the unit loses power during a
code upgrade or during a configuration save.
For the recovery to occur, you must have the following installed and available
to the Campus-REX2:
•
•
A BOOTP server must be configured and available to respond to the
MAC address of the Campus-REX2 with the following information:
–
IP address and subnet mask
–
Gateway IP address, if required
–
TFTP server IP address
–
recovery image filename
A TFTP server must be active and available and contain the recovery
image file (name provided to Campus-REX2 by BOOTP server).
The Campus-REX2 automatically performs the following when recovering
software:
1
After internal processing, the Campus-REX2 sends a BOOTP request
out both the LINE and LAN interfaces. These requests are transmitted
until a reply is received.
2
After the BOOTP response is received by the Campus-REX2, it attempts
to download code from the TFTP server (TFTP server IP address
provided to Campus-REX2 by BOOTP server).
3
After the new image is downloaded, the Campus-REX2 automatically
boots the new image.
Your Campus-REX2 is now in a normal operating state and you can manage
it as appropriate.

SETTING THE HDSL PARAMETERS
The Campus-REX2 is set to operate in Standard Mode with a T1
(1.544 Mbps) HDSL Rate. This is compatible with other Campus-RS
products and with Campus-T1 desktop units and line units. If this is the
preferred setting for your system, proceed to “Configuring the
Campus-REX2” on page 103. Otherwise, follow the steps in this section to
adjust the HDSL transmission rate.
Changes to the HDSL operating mode or transmission rate are
not automatically made to the remote unit. These changes
must be made at both the local and remote units for the HDSL
link to be re-established. If the remote unit is not easily
accessible, you can follow the instructions in “Logging On a
Remote Campus Unit” on page 15 to use an PC for a remote
logon (if an HDSL link is up) and make the preferred change.
When you change the HDSL settings for the remote unit, the
HDSL link is lost; it is re-established when you make the
identical change(s) to the local unit.
You can use the default HDSL setting for your Campus-RS unit (when also
using the default settings on the remote unit to which this unit connects)
which are:
•
standard for the HDSL operating mode
•
auto for the transceiver mode (determines which device is the master
or slave)
•
T1 for the HDSL rate
Campus-REX2 RS Interface Card User Manual

Chapter 7 - Using the LCD for Configuration and Management
If you want to change any of these parameters, select one of the following
sections based on the HDSL operating mode you will use. Campus-RS offers
these two HDSL operating modes:
•
•
Standard mode (below) provides compatibility between a Campus-RS
product and an earlier Campus product (legacy Campus) that has a
HDSL interface including T1, E1, or 768:
–
for T1, the maximum transmission rate is 1.544 Mbps over 2 pairs
–
for E1, the maximum transmission rate is 2.048 Mbps over 2 pairs
–
for 768, the transmission rate is 768 kbps over 1 pair
Extended mode (page 101) provides a fractional (n x 64) rate selection
between the HDSL interfaces of two Campus-RS products. The rate is
selectable as follows:
–
for 1 pair in 64 kbps increments, starting at 128 kbps up to

can then install any of the customer interface cards listed on page 120 for
the customer-side network connection.
•
Campus-Star chassis—This chassis or concentrator provides aggregation
for up to 14 DSL line connections. Each line connection is made using a
DSL line unit that connects to a DSL line unit in another Star Chassis or
to the DSL interface of a desktop unit. You can then install any one of the
customer interface cards listed below to complement each DSL line unit
in the chassis for the customer-side network connection.
You can install a Campus-RS Management Unit (CMU) into the chassis
for SNMP management of components in the chassis and for
management of elements attached to the chassis.

APPLICATION
The Campus-REX2 must be installed into a Campus-RS or
Campus-HRS desktop unit or with a Campus-RS or
Campus-HRS line unit. It cannot be installed in an older
Campus desktop unit or with an older Campus line unit.
The Campus system, implementing Campus-REX2 interface cards, provides
a connection between geographically distributed Ethernet Local Area
Networks (LANs) in a campus environment. The Campus-REX2 performs
transparent 802.3 MAC bridging or IP routing. You can use existing
telephone-grade copper wiring as the HDSL transmission medium.
When installed in a Campus-RS desktop unit or Campus-Star chassis, the
Campus-REX2 functions as a remote bridge or IP router. You can use the
Campus-REX2 to extend subnetworks to remote sites within a campus. Or,
for sites separated by greater distances, you can use the Campus-REX2 to
connect them through a public T1/E1 Wide Area Network (WAN). See
“Point-to-Point LAN Extension” and “LAN Connections Over a WAN” on
page 123 for more information.
Campus-REX2 software provides complete main bridging tasks of learning,
forwarding, filtering, and hashing/buffer management, 802.1d Spanning Tree
protocol, 802.3 drivers, packet sequencing, segmentation and reassembly,
and other local tasks.
The Campus-REX2 10/100Base-T interface operates in either
half- or full-duplex mode which is determined by autosensing
its network connection. Both the LCD menu and console
menu displays the mode.
The Campus-REX2 performs full-bandwidth filtering on the 10/100Base-T
port and forwarding at the selected transmission rate.

LAN Connections Over a WAN
When LANs are distributed over a large physical area (such as within a
metropolitan area) or cabling is not available between sites, you can lease
appropriate unloaded copper pairs from a local carrier for LAN connectivity.
For transport over public networks, you can connect the public T1 network
(DSX-1 signal) to the LAN through desktop units with CSU/DSX-1 interface
cards and the Campus-REX2 in a desktop unit. This application, as shown in
the following figure, simplifies access to public high-speed WANs for LAN
connectivity to remote sites.

MAC-LEVEL BRIDGING AND SPANNING TREE
PROTOCOL
The following sections describe the MAC-level bridge and the Spanning Tree
algorithm function.
About MAC-Level Bridging
A bridge moves information across an internetwork from a source to a
destination at the link layer (of an OSI reference model). The information is
sent to a physical address known as a Media Access Control (MAC) address.
The Campus-REX2 provides transparent Ethernet MAC-level bridging. It is
a completely self-contained bridge with a CPU, memory subsystems (RAM,
Flash, etc.), an Ethernet controller and Ethernet drivers, and other glue logic.
It provides complete main bridging tasks of learning, forwarding, filtering,
and hashing/buffer management. Additionally, it offers 802.1d Spanning
Tree protocol, packet encapsulation (through cHDLC or PPP framing), and
other local tasks.
About Spanning Tree Protocol
Spanning Tree protocol creates a logical topology to overlay a physical
network. This overlay disables all loops in the data path. Enabling Spanning
Tree ensures a unique, primary path from any node on a network to any other
node. Also, if the primary path is lost, Spanning Tree creates a new primary
path by enabling links in the physical network that were previously disabled
in creating the active topology. The following figure shows an example of
Spanning Tree.

To enable or disable Spanning Tree, see “Configuring Spanning Tree
Protocol” on page 33. The following elements are required for managing the
Spanning Tree active topology:
•
assigning a priority to each bridge relative to all bridges within the
bridged LAN
•
assigning a priority to each bridge port relative to all ports on a bridge
•
assigning a path cost to each port
IP ROUTING
The Campus-REX2 offers both dynamic and static routing.
Static Routing
Through the static IP routing feature, you can configure the Campus-REX2
as an IP router with statically programmed route entries. You can enable this
function as a security feature to prevent eavesdropping and to provide
broadcast filtering, as well as to specify multiple destination gateways. When
static IP routing is enabled, you can access only specific remote IP subnets or
hosts.
Since IP routers make forward or filter decisions based on the network-layer
IP address instead of the MAC hardware address, MAC-level broadcast
frames are prevented from reaching unwanted destinations in the network.
The following example shows a simple Internet Service Provider (ISP) site
that uses the static IP routing feature to filter MAC-level broadcast frames
sourced by ISP Subscriber A from reaching ISP Subscriber B. In this
example, all frames from Subscriber A and Subscriber B are directed to the
router at the Network Access Provider site. From there, frames from both
subscribers are forwarded directly to the Internet.
126
Campus-REX2 RS Interface Card User Manual
Chapter 8 - Internetworking and Management Overview
The figure on page 128 shows a more complex example of multiple gateways
that use static IP routing to route packets sourced from specific users to
different destination gateways. In this example, packets from each subscriber
are routed through a common hub to a router dedicated to that subscriber.
Campus-REX2 RS Interface Card User Manual
127
Chapter 8 - Internetworking and Management Overview
Configure a Static Route entry in any of the external routers that may have
been specified as a Default Router IP address or as a Gateway address in the
Campus-REX2. You may also configure the Campus-REX2 to send periodic
route updates using Routing Information Protocol (RIP) so that other external
routers can automatically update their routing tables. This implementation
prevents other parties from eavesdropping to discover routes to remote sites
connected through the HDSL line. The format of this entry varies among
different router vendors, but it will typically be in the form of Destination,
Mask, and Next Hop Gateway, where:
•
destination is the remote IP subnet or host address
•
gateway is the LAN IP address of the Campus-REX2 on the same subnet
as the external router
The following figure shows an example of a point-to-point HDSL system
with hypothetical parameter values.

Dynamic Routing
Dynamic Routing uses protocols such as RIP and RIPv2 to automatically
learn the route or next hop it must take based on the IP address of the
destination contained in the datagram.
Campus-REX2 IP Addresses
Each Campus-REX2 unit has two IP addresses, the LAN address and the Line
address. In the figure on page 131, the non-shaded side of the Campus-REX2
indicates the LAN address, which is for the Ethernet (10/100Base-T)
connection. The shaded side of the Campus-REX2 is the IP Line address,
Campus-REX2 RS Interface Card User Manual
129
Chapter 8 - Internetworking and Management Overview
which is for the HDSL connection. Note that the IP Line address is different
from the LAN addresses. When connecting two Campus-REX2 units
point-to-point through HDSL, the IP Line addresses are completely isolated
and hidden from the rest of the network. You can assign any subnet to the
Line IP addresses.
When routing, data travels one hop at a time. The figure below shows
destination and next hop IP addresses. The destination address indicates the
network and subnetwork of the next hop. The next hop is the next-stop IP
address node. The default gateway is the upstream routing device. Use this
example to help you determine/record static IP routing addresses.

Chapter 8 - Internetworking and Management Overview
MANAGEMENT PROTOCOLS
SNMP is used for remote configuration of system and bridge parameters,
monitoring statistics, and performing advanced management. FTP is used for
the Campus-REX2 to download system software code.
SNMP
This messaging protocol specifies how to send information between a
Network Management Station (NMS) or Element Management System
(EMS) and managed devices on a network.
SNMP Functions
Managed devices (such as the Campus-REX2) have agent software or
firmware that interprets SNMP requests and responds to them. The EMS
communicates with the agents in the managed devices to:
•
set configuration options
•
read configuration information
•
read status parameters
A Management Information Base (MIB) defines these configuration and
status parameters (see “MIB and Trap Support” on page 133). The Internet
Engineering Task Force (IETF) specifies standard MIBs for certain types of
devices, ensuring that any NMS can manage them. Additionally, vendors can
issue proprietary MIBs for their devices that provide higher management
functionality.
Campus-REX2 SNMP Agent
An agent is software or firmware code resident in managed devices (such as
the Campus-REX2, modems, nodes, routers and hubs). Agents translate data
on remote networks into code the EMS can read. The EMS uses SNMP as the
transport mechanism to communicate with an agent. SNMP uses the standard
Internet Protocol (IP) to transport incoming and outgoing messages to the
appropriate agent or NMS address. Each SNMP command requires an IP
address or NMS from the agent to transport these messages.
132
Campus-REX2 RS Interface Card User Manual
Chapter 8 - Internetworking and Management Overview
The Campus-REX2 provides an SNMP agent that supports several MIBs for
the management of the system. The SNMP agent can process datagrams
received from both the Ethernet interface (LAN) and the HDSL interface
(Line). See “MIB and Trap Support” on page 133 for a list of MIBS that are
supported.
Telnet
Telnet is a standard TCP/IP protocol used for remote terminal service. Use
telnet protocol to access the Campus unit for configuration and management
over the Internet. From the Windows Start menu, select Run. Enter the telnet
command and the IP address for the Campus-REX2 (default IP address is
192.168.1.1). The timeout for disconnecting a telnet session is five minutes
(time frame with no keyboard activity to the Campus unit).
FTP
File Transfer Protocol is a TCP/IP standard that is used for moving files
between devices. Use FTP when you are downloading upgrade software to
the Campus unit from a server or other network device.
MIB AND TRAP SUPPORT
Each managed device has configuration, status, and statistical information
that defines its functionality and operational capabilities. All of these
elements make up the MIB for the device being managed. The MIB defines
the kind of information an NMS can retrieve from a managed device and the
settings an NMS can control in a managed device.
The Campus-REX2 supports the following MIBs:
•
RFC 1213/STD 17, Management Information Base for Network
Management of TCP/IP-Based Internets: MIB-II. Covers: system,
interfaces, IP, ICMP, UDP, and SNMP groups. The Ethernet interface
has the ifIndex value of 1.
•
RFC 1215, A Convention for Defining Traps for Use with the SNMP.
Covers: ColdStart, linkUp, linkDown, and authenticationFailure traps.
Link status traps are sent for events related to Ethernet.
Campus-REX2 RS Interface Card User Manual
133
Chapter 8 - Internetworking and Management Overview
•
RFC 1493, Definition of Managed Objects for Bridges. Covers: Base,
Spanning Tree, and transparent bridging groups. The Spanning Tree
MIB can only be accessed if the Spanning Tree protocol is enabled.
•
PG-REX2-MIB, an enterprise specific MIB designed for the agent in the
Campus-REX2 for managing the HDSL portion of the unit.
The Campus-REX2 sends traps to devices on the network, which you
configured as trap receivers, when events or alarms occur. The following are
traps that the Campus-REX2 can issue:
•
coldStart
•
warmStart
•
linkDown
•
linkUp
•
authenticationFailure
DHCP
Dynamic Host Configuration Protocol (DHCP) is the protocol used by the
Campus-REX2 to obtain all necessary configuration information including an
IP address. The LAN port can be configured as a DHCP client where it will
automatically obtain its configuration information from a DHCP server on the
LAN.
The Campus-REX2 can provide DHCP relay services to devices on its LAN.
As a DHCP relay agent, the Campus-REX2 can forward requests for IP
configuration to a DHCP server for which you configure the IP address.
134
Campus-REX2 RS Interface Card User Manual
Chapter 8 - Internetworking and Management Overview
ENCAPSULATION PROTOCOLS
You can select from two packet encapsulation formats for Ethernet data for
the Campus-REX2:
•
compressed High-level Data Link Control (cHDLC)
•
Point-to-Point Protocol (PPP)
The default setting is cHDLC and should be used in applications with another
Campus-REX2. Use PPP only if the remote unit is a synchronous interface
card, such as V.35.
When PPP is selected for bridging mode, the Campus-REX2 runs the
Bridging Control Protocol (BCP) RFC 1638. PPP provides interoperability
with other product types. cHDLC is a compressed version of the
encapsulation protocol and is preferable when there is like equipment (ADC
equipment).

HDSL
All earlier versions of Campus products are manufactured to operate at a
single HDSL transmission rate, while the Campus-RS transmission rate is
user-selectable. To support compatibility with earlier Campus Products, the
following configuration options must be set on the Campus-REX2:
•
Set the HDSL Operating Mode to Standard Mode.
•
Set the Standard Mode HDSL Rate to T1, E1, or 768, to match the rate
of the earlier product.
For information on setting these options, see “Selecting HDSL Parameters”
on page 21.

When connecting to another Campus-RS desktop unit or line unit, Standard
Mode is still supported, providing access to HDSL transmission rates of T1,
E1 and 768 kbps. In addition, the Campus-RS system can be configured to
support an extended set of HDSL transmission rates, over either one or two
HDSL loops.
To support these additional transmission rates, set the following options on
the Campus-REX2:
•
Set the HDSL Operating Mode to Extended Mode.
•
Set the Extended Mode Loop Configuration to 1 Loop or 2 Loops,
depending on the physical layout of your HDSL network.
•
Set the Extended Mode HDSL Rate to the required setting.
The range of rates available for the HDSL Rate depends on the setting of
the Extended Mode Loop Configuration:
–
1 Loop HDSL rate settings are between 128 kbps and 1.152 Mbps,
in 64 kbps increments.
–
2 Loop HDSL rate settings are between 256 kbps and 2.304 Mbps,
in 128 kbps increments.
Not all of these modes and rates are available if the remote
Campus-RS system does not support them. Refer to the
remote interface card User Manual to see the HDSL modes
and rates supported by the card.
For information on setting these options, see “Selecting HDSL Parameters”
on page 21.
Campus-REX2 RS Interface Card User Manual
137
Chapter 8 - Internetworking and Management Overview
Compatibility with Earlier Versions of Campus Products
Campus-RS Desktop and line units are fully compatible with most of the
earlier versions of Campus products, including Campus-E1, Campus-T1, and
Campus-768. The Campus-RS Desktop and line units are not currently
compatible with Campus-384 products.
Furthermore, if a Campus-RS unit is connected over an HDSL link to an
earlier Campus product, and if either unit has the HDSL Transceiver (XCVR)
Mode set to AUTO, the HDSL link may not operate properly.
When operating the Campus-RS product with an earlier version of the
Campus products, to avoid any problems with link startup or operation, it is
recommended that the Transceiver Mode be set as follows:
•
Campus-RS = MASTER
•
Campus E1/T1/768 = SLAVE
If one or both units are already set to AUTO and the HDSL link is active,
disconnect the HDSL link, change the settings as recommended, and
reconnect the link. This will assure the link integrity on any subsequent
startups.
This situation does not apply to a circuit with two Campus-RS
units. You may leave the units set to their default setting of
AUTO, and they will operate properly.
