CHAPTER 1
INTRODUCTION
•
This chapter provides information about the features and performance of the WPIM-S/T. It also briefly explains Integrated Services Digital
Network ( ISDN ), call back-up, and the WAN protocols supported by the
WPIM-S/T.
•
Note the following requirements for successful operation of this device:
Install the WPIM-S/T in a Wide Area Network host platform. Refer to
Chapter 2 for directions on installation procedures. Refer to the appropriate host platform manual (i.e., the Cabletron Systems CSX400 and CSX400-DC Installation Guide ) for other installation and troubleshooting procedures.
Use the Graphical User Interface QuickSET to fully configure the
WPIM-S/T. Due to the automation of setup features, QuickSET use is strongly recommended. However, Chapter 3 contains additional information on configuring the WPIM-S/T, which can be done independent of QuickSET.
NOTE
The device or module in which the WPIM-S/T is to be installed may be referred to as the host platform in this document.
1.1
WPIM-S/T FEATURES
The WPIM-S/T provides ISDN 128 Kbps Basic Rate Interface ( BRI ) in a backup or fail-over capacity for the CSX400, HSIM-W6, or other devices 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 bearer (B) 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 nailed-up PPP connection fails. The WPIM-S/T serves 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
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.

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 ).

NOTE
The user must determine the settings that will work for their 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 failed and there is traffic to be forwarded across the back-up SVC.
This example assumes the setup shown in Figure 3-5 , using two 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.

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 interface 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.
NOTE
For any switched medium like ISDN there are two types of 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. However, if additional interfaces have been created for which their need is unknown, then DoD should be disabled. To do this, set the backup interface 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).
NOTE
If the interface is active, you cannot configure backup.
De-activate the interface before proceeding.

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. Likewise, 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.

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.
