1.1 WPIM-S/T FEATURES

The WPIM-S/T provides ISDN 128 Kbps Basic Rate Interface
backup or fail-over capacity for the CSX400, HSIM-W6, or other de vices
in which the WPIM-S/T can be installed. The WPIM-S/T provides an
ISDN back-up link for a remote site or branch office when the primary
connection for a

frame relay

or leased line is lost or becomes disabled.

WPIM-S/T User’s Guide 1-1

Chapter 1:

Introduction

1.1.1 Performance

The capability of the WPIM-S/T is 128 Kbps when both B Channels are
active.

There are several user-configurable timers that control the connect and
disconnect time-outs to provide optimum performance. These are detailed
in Chapter 3.

1.2 ISDN

ISDN provides inexpensive switched digital access to remote sites. The
ISDN BRI standard provides for two high-speed 64-Kbps

channel

s used for voice or data connections and one 16-Kbps signaling

data (D) channel used for call setup, signaling, and other information.
ISDN allows all types of information to be transmitted including voice,
data, fax, and video. Multiple devices can be linked to a single ISDN
connection, each having their own telephone number. Two or more
channels can be combined into a single larger transmission pipe offering
variable transmission speeds.

1.3 ISDN CALL BACK-UP

The ISDN call back-up feature provides a back-up link for a remote site
or branch office when one or more primary WAN interfaces for a frame
relay circuit or a
as the backup medium for this primary connection, using the ISDN
interfaces to back-up any primary interfaces that have been configured for
ISDN back-up.

The following are two reasons to use ISDN call back-up:

•

Hardware failure of a nailed-up PPP connection

•

PPP

fails to connect (software problem)

Use call back-up if either of the following conditions exist when using
Frame Relay:

•

DLCI circuit fails to connect in 12 minutes

• DLCI goes inactive

nailed-up PPP

connection fails. The WPIM-S/T serves

1-2 WPIM-S/T User’s Guide

WAN Protocols

The following is one circumstance in which it might not be advisable to
use call back-up:

• When going point-to-multipoint, setting back-up on the head-end side

is not recommended. If any DLCI fails, the back-up would be
activated. This may be cost prohibitive.

1.3.1 Call Back-up Topology

In Call Back-up topology, two channels are connected, but one of them is
a Switched Virtual Circuit (SVC) that is only activated upon failure of the
primary channel. The primary channel is a Permanent Virtual Circuit
(PVC) running Frame Relay or PPP. The Back-up channel is either
ISDN BRI or PPP.

Table 1-1 shows the supported configurations at the initial release of the

call back-up feature.

1.4 WAN PROTOCOLS

The WPIM-S/T interface supports ISDN BRI, which encapsulates PPP.
For more information, refer to the host platform manual and the Release
Notes included with the host platform for a list of current supported
protocols.

ISDN BRI is a switched Data Link layer control protocol that uses digital
signaling to place a call into an ISDN network. Once the call is made,
PPP is then used to transfer data.

WPIM-S/T User’s Guide 1-3

Chapter 1: Introduction

PPP is a Data Link layer, industry-standard WAN protocol, used to
transfer multi-protocol data traffic over point-to-point connections. With
this protocol, options such as security, data compression, and network
protocols can be negotiated over the connection.

Frame Relay is a packet-switching data communications protocol that
statistically multiplexes many data conversations over a single
transmission link. Data compression allows Frame Relay to negotiate
compression over Frame Relay PVCs.

1.5 MIB SUPPORT

Refer to the Release Notes included with the host platform for a list of all
MIBs supported by the WPIM-S/T. For information about how to extract
and compile individual MIBs, contact Cabletron Systems Global Call
Center (see Getting Help).

particular network for the following parameters. Therefore, no
settings are indicated, other than default.

The fields for the BoD feature are described as follows:

Bandwidth-on-Demand (BoD) option

Specifies whether or not MLP support is desired. To successfully
negotiate MLP, both devices must support MLP. The default setting is
DISABLE.

Line Utilization (LU) Threshold (LUT)%

Specifies a line utilization threshold (%) value to compare against the
linear weighted percentage by which to determine when more or less
bandwidth is to be added or removed. The default setting is 50.

History time in seconds to compute LU Avg. (LUA)

Specifies a time value in seconds over which the line utilization
percentage is averaged by the linear weighted percentage algorithm. The
default setting is 5.

# of LUA computation(s) > LUT for when to add BW

Specifies the number of samples for which the condition for adding more
bandwidth must persist before additional bandwidth is added. This
parameter is used to filter out traffic bursts. The value should be chosen
such that the time it takes to add more bandwidth is less than the time the
traffic will exceed the “line threshold”. This will avoid the additional cost
of adding unnecessary bandwidth. The default setting is 1.

# of LUA computation(s) < LUT for when to remove BW

Specifies the number of seconds that the output has fallen below the line
threshold before previously added additional bandwidth is removed. The
default value is 5.

Maximum # of calls allowed including the 1st call

Specifies the maximum number of channels an MLP call is allowed. The
value accounts for the channel used to establish the original/first link. The
default setting is 1.

When modifying the “Maximum # of calls allowed” parameter, which
accounts for the first call, a check is made against the maximum profiles
setting for that interface. Although the maximum possible value allowed
is shown to be 20, the true maximum is the current maximum profiles
setting for that interface which cannot exceed 20.

3-8 WPIM-S/T User’s Guide

Local Management Screen Overviews

# of calls to increase by when more BW is needed

Specifies the incremental number of channels by which to increase
additional bandwidth. Specifically, channels can be added in multiples.
The default setting is 1.

# of calls to decrease by when less BW is needed

Specifies the number of channels by which to remove bandwidth.
Specifically, channels can be removed in multiples. The default setting
is 1.

Avg packet size used to determine when to fragment

Specifies the average packet size by which to determine when it is best to
split a packet. This is an attempt to minimize the amount of buffering
necessary at the remote device to maintain packet sequence. The default
setting is 260.

Either side controls Bandwidth

Specifies whether or not bandwidth changes are permitted by either side,
i.e., both parties. Normally only the caller controls the bandwidth. The
default setting is DISABLE.

Call Back-up Configuration

3.2 CALL BACK-UP CONFIGURATION

This section provides instructions for configuring the WPIM-S/T to
automatically back-up a PPP dedicated/permanent connection or a Frame
Relay PVC using a dial-up ISDN. These are the two primary uses. All
connections configured as call back-up are continuously monitored for a
failed condition. Whenever a primary connection with call back-up fails,
the back-up call is automatically made using Dial-on-Demand (DoD).
Once the failed connection is restored the back-up call may be
automatically closed. DoD automatically brings up the back-up SVC
connection whenever the primary connection has f ailed and there is traffic
to be forwarded across the back-up SVC.

This example assumes the setup shown in Figure 3-5, using tw o CSX400s
with primary connections using WPIM-T1s (WPIM-E1, WPIM-DDS, or
WPIM-SY could also be used) and with WPIM-S/T back-up modules
installed in each CSX400. The NT-1 is needed if the connection to the
Telco cloud has a U interface.

3.2.3 Configure Backup

Use the following Network Tools command to configure backup:

setbackup [PRIMARYIFACENUM] [BACKUPIFACENUM]
[TIMETOCONNECT] [TIMETODISCONNECT]
[CONNECTRETRIESNUM]
[TIMEBETWEENCONNETRETRIES][BACKUPOVERRIDE]

PRIMARYIFACENUM

The number of the primary interface that is going to be backed up.

BACKUPIFACENUM

The number of the interface assigned as the backup interface to the
primary interface.

TIMETOCONNECT

How long the system will wait (in seconds) before attempting to switch
over to the backup interface. Default is zero. Allowed values are in
increments of five seconds.

TIMETODISCONNECT

How long the system will wait (in seconds) before attempting to switch
over to the primary interface once the primary interf ace has been restored.
Default is 90 seconds. Allowed values are in increments of five seconds.

CONNECTRETRIESNUM

Specifies the number of tries to bring up the backup interface before
giving up. The default is three. Allowed values are in increments of one.

TIMEBETWEENCONNETRETRIES

Specifies the time interval between tries to bring up the backup interface.
The default is 30 seconds. Allowed values are in increments of five
seconds. Zero is allowed but not advisable.

WPIM-S/T User’s Guide 3-17

Chapter 3: Local Management

BACKUPOVERRIDE

Specifies if the backup interface will disconnect whenever the primary
interface is restored (reconnected). Choosing ENABLED for this
command will not disconnect the backup interface even though the
primary interface is restored. Used specifically when the primary
interface has an intermittent problem, as it is desirable for the backup
interface to stay connected until the primary interface problem is
corrected. Once the primary connection is fully operational,
BACKUPOVERRIDE should be set to DISABLED, the default value.

For any switched medium like ISDN there are two types of

NOTE

interfaces, primary and secondary (backup). Primary interfaces
automatically attempt to connect using DoD. Because of this, it
is recommended not to create any unnecessary interfaces
because they will consume unnecessary time in trying to
connect. Howe ver, if additional interfaces hav e been created for
which their need is unknown, then DoD should be disabled. To
do this, set the backup interf ace to itself. e.g., setbackup 12 12.
Do this for each interface that should have DoD disabled. This
recommendation also applies to Dial-in only interfaces (i.e.,
answer mode interfaces.

Example 1:
There is a nailed-up PPP interface #3, and to back it up, ISDN interface
#4 is used with the default values. Use this Network Tools command:

setbackup 3 4

Example 2:

For answer mode only:

setbackup 3 to 3

Answer mode only is set. This will set the backup interface to itself if the
ISDN interface is to be used only as a dial-in circuit (i.e., answer mode
only).

If the interface is active, you cannot configure backup.

NOTE

De-activate the interface before proceeding.

3.2.4 Set Idle Timeouts

Set the receive and transmit idle timeouts for backup interfaces using
Network Tools. This command automatically disconnects an idle
switched interface within the parameters:

setidletimeout [IFACENUM] [TRANSMITIDLETIMEOUT]
[RECEIVEIDLETIMEOUT]

IFACENUM

The number of the interface to be configured.

TRANSMITIDLETIMEOUT

The idle time out parameter for the transmit time out.

RECEIVEIDLETIMEOUT

The idle time out parameter for the receive time out.
Example: To set the receive time out to 180 seconds and the transmit side

to 600 seconds for ISDN interface #4, use this command:

setidletimeout 4 180 600

3.2.5 Configure the D Channel

Use the following command in Network Tools to set the switch type:

setswitchtype [WANPORTNUM] [SWITCHTYPE]

WANPORTNUM

If the WPIM-S/T occupies WAN port number one, use 1, if it occupies
port number two, use 2 as the WANPORTNUM.

SWITCHTYPE

Choose between the types of ISDN BRI switches. The choices are NI1,
DMS100, and ATT5 (default is NI1).

3.2.6 Set Phone Numbers and SPIDs for the Port

The following Network Tools command is used to set the phone numbers
and the SPIDs:

setisdnbri [WANPORTNUM] [LDN1][SPID1] [LDN2] [SPID2]

WPIM-S/T User’s Guide 3-19

Chapter 3: Local Management

LDN1

The first Local Directory Number. Likewise, LDN2 is the second Local
Directory Number.

SPID1

The first Service Profile Identifier . Lik ewise, SPID2 is the second Service
Profile Identifier.

SPID format: [XXXYYYZZZZ] [01] [01]

Where XXX represents the area code, YYY represents the prefix, and
ZZZZ represents the local number. [01] [01] is the fixed suffix.

Example 1: For the first WAN port to be configured for ISDN, issue the
command:

setisdnbri 1 555 1000 0555100001 5553000 0555300001

For the second WAN port to be configured, issue the command:

setisdnbri 2 5551000 0555100001 5553000 0555300001

The command also allows for skipping or clearing any entry by using the
key letters S (or s) to skip the field, and C (or c) to clear the field.

Example 2: To skip LDN1 and SPID1, change LDN2, and clear SPID 2,
issue the following command:

setisdnbri 2 s s 0555600001 c

3.2.7 Set Maximum Number of Neighbor/Remote

Profiles

A neighbor/remote profile describes a possible connection. The maximum
should be set to account for support of PPP Multilink. If PPP Multilink is
used, then the number of profiles must accommodate the maximum
possible number of additional “more BW” connections/calls desired.
Consequently, each neighbor profile would then describe a possible
connection to the same remote end point (user). Two profiles will be set
up for the first ISDN interface. This means that the first ISDN interface
can be used to connect (call) two different end users or the same end user
twice (e.g., Multilink). The default is one profile per ISDN interface.

Use the Network Tools command:

setmaxprofiles [IFACENUM] [MAXPROFILESNUM]

Example: To set two profiles for ISDN interface #4 issue the command:

setmaxprofiles 4 2

3.2.8 Reset

The host platform must be reset at this time. Reset the host platform or
disconnect the ISDN line (this forces the Telco to re-initialize). Refer to
the host platform user’s guide in order to reset the platform.

3.2.9 Configure the Profiles

Configure the profiles and specify phone numbers for backup interfaces.
Use Local Management to configure BoD (submenu of the profiles menu)
and enable using MLP if desired. Refer to Section 3.1.2 for details.

NOTES

Set max profiles, total profiles to allow multilink (QuickSET
does this automatically).

Multilink is dynamic and needs an interface to support the link.

3.2.10 Verify Status

Use the Network Tools command idsnstat to verify the D channel status;
it should read active. The isdnstat command is used to display the ISDN
settings, including the switch type, LDNs, SPIDs, and the operational
status of the D channel. This command is normally used to verify that the
switch and the WPIM-S/T are working properly. If the settings are not
correct, or the D channel is not operational, the situation must be
corrected before continuing the configuration. The connection must be
operational or the backup configuration will not work.

isdnstat [WANPORTNUM]

Use the Network Tools commands ct and dt to test the line by doing a
manual connect or disconnect:

ct [IFACENUM] connects (places) a call for the interface designated.
dt [IFACENUM] disconnects (hangs up) the call.

These three Network Tools commands allow the user to check whether or
not the ISDN line and profile(s) have been configured properly and that a
connection is possible.

3.2.11 Configure Primary Lines and Routing
