CONFIGURING

HDSL PARAMETERS

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 othe r Campus-RS and Campus -HRS products (in cluding the
Campus-T1 desktop units and line units) if you choose to operate them in
their default configuration.

For: See Page:

Configuring HDSL Parameters 20
Configuring HDSL Alarms 26

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 instruct ions 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.

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) pr ovides a fractional rate se lection 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

CONFIGURING THE REX2

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 t o dis abled. If,
however, you require to change any of these parameters for implementing
your network, use the procedures in this chapter.

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 So urce to HDSL if the rem ote unit is set to

Internal or Data Port.

– Set the Timing So urce to Internal if the remote unit is set to

HDSL.

See the Campus-RS Fractional Interface Card User Manual for

Configuring Routing Protocol, Encapsulation and Timing

The Campus-REX2, as a default configuration, is set to bridge data. You can,
however, change this setting for the Campus-REX2 to be a router. In the
following procedures, you can set up the router encapsulation and timing
source.

You can only configure the Campus-REX2 as a router through
connection to the Console port or a Telnet session. Most
router options are not configurable through the LCD menus.

3 To change the timing source, type then press . Select a timing

3 ENTER

source setting:

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

oscillator

• HDSL which takes its timing from the HDSL link
The Timing Source option determines the sour ce 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.

Campus-REX2 RS Inter face Card User Manual 45

Chapter 3 - Configuring the REX2

• 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 So urce to HDSL if the rem ote unit is set to

Internal or Data Port.

– Set the Timing So urce 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 connec ted to a Cam pus unit wi th a Campu s

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 destinati on netw ork, sub net ma sk,
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 addr ess of 0.0.0 .0 with a subnet mask of 0.0.0. 0 and
then entering the IP address for the default gateway.

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-REX 2 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.
