KBU 64 User Manual The available settings are: 300 300 - Asynchronous only 600 1K2 2K4 600 - 38K4 inclusive 4K8 suitable for Asynchronous/synchronous communication 9K6 19K2 38K4 48K 56K ≥48K - Synchronous only 64K Note that with leased circuit data or clock rates of less than 600bit/s, talkwire restoration cannot be achieved. When calls are made to the USA or other destinations which are 56K, the NETWORK parameter must be set to SWITCH56.
Configuration Commands 4.8.3 Altering the Asynchronous Character Length Asynchronous character lengths of 7, 8, 9, 10, 11 & 12 can be supported independently on each channel, the character length counting data, parity, start and stop bits. The selected character length is displayed in the STATUS screen. Typing; 1> CHAR[CR] displays the selected character length.
KBU 64 User Manual The factory default CHAR setting is 10 bits. When a channel is set for synchronous operation the CHAR parameter setting is ignored. 4.8.4 Altering the Network Type - NETWORK Parameter The KBU 64 can make switched 56K data calls to the USA, either to another KBU 64, a Fivemere 6421 or another manufacturer's TA on a 'per channel basis'. 1> NETWORK[CR] displays the current setting of this parameter for channel 1 (read Channel 2 by typing 2>).
Configuration Commands 4.8.5 The User Rate Switch The default setting is ‘OFF’. The User Rate switch can be used to enable or disable the transmission of user rate information when a call is made to the network. Type: 1> SET USERRATE ON[CR] or 1> SET USERRATE OFF[CR] to enable or disable the feature. Some TA’s check user rate information, rejecting the call if they receive the user rate information incorrectly.
KBU 64 User Manual LOOP - Can also be used when you always wish to detect your own data for purposes of restoral. You can set LOOP ‘ON’ permanently for this purpose, when it will automatically be dropped upon sending data. 3. RXDATA - when set, monitors the line for any transition. When ‘RESTORE’ is set to AUTO, an automatic restore is performed when a transition is detected, providing that transitions are still detected within both the DATALOSS and RESTORE time delay settings.
Configuration Commands Please see also section 4.8.4, for the setting of the NETWORK parameter, when 56K speed is set. The physical link jumpers must also be set as explained in section 2. When RA is set to V, both transmit and receive clocks must be present from the digital leased circuit, for a talkwire restoral to occur. With RA set to X, only the single clock ‘S’ is used. 4.10 Altering Command Port Speed The COMMAND port is set to communicate at 9600 bit/s as factory default.
KBU 64 User Manual EVENT messages are all messages, i.e. ‘Dialling’, ‘Ringing’, ‘Answering’ etc. ALERT messages are user defined messages prefixed by the word ‘ALERT’. Where these occur on the ALARM port, they also carry a time and date stamp. The current setting of the LOG command can be viewed on the KBU 64 status screen (by typing 1 (or 2)>STATUS). This is displayed on the ALARM PORT line. To alter the current setting of the ALARM message format: 1> SET LOG xx[CR] where xx is OFF, ON or ALERT.
Configuration Commands To display the current setting of the ALERTs, from either command line prompt, type: 1> ALERT[CR] Alert ACTIVE INACTIVE CALL BACKUP RESTORE ISDNPASS ISDNFAIL CONNECT DISCONNECT PASSWORD CHANSTATE Chan 1 ON ON ON ON ON ON ON ON ON ON ON Chan 2 ON ON ON ON ON ON ON ON ON ON ON To alter an Alert event, from the command prompt, type: 1> SET ALERT CALL xx[CR] where xx is ON or OFF.
KBU 64 User Manual Below is a description of the definable ALERTs: 4–18 ACTIVE Indicates that the Kilostream line is operating correctly. INACTIVE Indicates that a Kilostream line failure has been detected. CALL An incoming ISDN call has been received. BACKUP Backup to the ISDN has been initiated. RESTORE Connection to the Kilostream line has been restored. ISDNPASS The ISDN line passed the periodic dial test. ISDNFAIL The ISDN line failed the periodic dial test.
Configuration Commands 4.13 Backup Initiation and Answering Configuration The KBU 64s at each end of a Kilostream link will detect line failure independently. It is also possible that the leased circuit fails in one direction only. If Kilostream backup operation is to be fully automatic, one unit must initiate the backup link (backup auto) and the other must answer it (answer auto).
KBU 64 User Manual 1> SET STORE n xxxxx/yyyyy[CR] where n represents a directory location ( 1 to 99), and xxxxx is the telephone number of a remote KBU 64 to which a call can be placed. yyyyy represents the sub-address number of the channel in the remote KBU. This field is optional and need not be part of the stored number string unless sub-addressing is used. The yyyyy field is from 1 to 5 alphanumeric user defined characters. (See section 4.19 for a description of sub-address usage.
Configuration Commands In MANUAL, the factory default mode, you will be notified of a failure on the link together with it’s cause. You must then initiate Backup manually from the command line prompt (see section 6). In AUTO, your KBU 64 will automatically backup a failed Kilostream link on detection of a failure of that link. You will see the cause (e.g. loss of clocks, data loss or NTU) indicated at the terminal. Refer to section 4.15 for details of how to configure the timers which trigger a backup call.

Configuration Commands ‘hh:mm’ and ‘HH:MM’ to 00:00 on all slots on a day, then backup will be completely disabled for that day. If you set the ‘hh:mm’ to 00:00, and ‘HH:MM’ to 24:00 then on that day the backup will be enabled all day, ending at midnight unless the next day backup is enabled from 00:00. You can be put this into any of the window slots (1 to 4) but for reasons of clarity it is better in slot 1.
KBU 64 User Manual 1> SET ANSWER xx[CR] where xx is AUTO, MAN or CLID Answering an incoming call on the ISDN does not route the data path away from the Kilostream line. It is only used to set up the ISDN call. The current setting of the ANSWER command can be viewed on the KBU 64’s STATUS[CR] screen. 4.13.
Configuration Commands To display CLID numbers of the active channel which have been stored under the calling line identification security system: 1> CLID[CR] Stored B1 CLIDs: 1 0793123456 2 09901234311 etc.
KBU 64 User Manual 1> SET CONNECT xx[CR] where xx is AUTO or MAN When set to MAN (this is the factory default/normal state), Talkwire commands control the connection. During an automatic backup call, the remote unit will receive a connect command from the unit that is performing the backup. The TALKWIRE parameter must therefore be set to ON.
Configuration Commands Setting the RESTORE parameter to AUTO causes the KBU 64 to control automatic leased circuit verification and switching of the user back to the leased circuit. Once the KBU has detected and checked the Kilostream link to be operational and safe for data it automatically re-connects the USER port to the Kilostream link, then hangs up the ISDN call. Data transfer now occurs over the Kilostream link. The Kilostream link then continues to be monitored again.
KBU 64 User Manual If any of these are disabled, then restoral will occur without checking for them. 4.13.9 Using C/DTR C/DTR configures the received control signal C/DTR on the USER port of the KBU 64. ‘C’ (Control) is used for an X21 interface, and ‘DTR’ is used for a V28 or V35 interface. 1> SET C/DTR xx[CR] where xx is NORMAL, FORCED, ANSWER or BACKUP When set to NORMAL, the USER supplied C/DTR signal is used by the KBU 64.
Configuration Commands xx is NORMAL or FORCED For speeds below 64Kbit/s, control signals are transferred across the ISDN backup link, and the output of I/DSR to the USER port is dependent on the C/DTR input at the remote KBU 64. When set to NORMAL, I/DSR is dependent on C/DTR at the remote KBU 64. Where control signals are not transferred, the I/DSR output signal is inactive. When set to FORCED, the I/DSR signal is always active during an ISDN backup.
KBU 64 User Manual Alternate redialling is automatically initiated if BACKUP is set to AUTO. Alternate redialling is also initiated automatically during manually entered BACKUP[CR] or DIAL[CR] commands when specific numbers or ranges of numbers have been defined in the command string. (see section 6 for details on manually initiated calls). The telephone number in STORE directory location 1 will be the first one tried when your KBU 64 initiates a backup call.
Configuration Commands Note: The time delays between an unsuccessful dial attempt and the next dial attempt, and that between the end and beginning of a cycle are user configured, as detailed in sections 4.15.13 and 4.15.14. 4.15 Configuring the Delay Timers The SET DELAY command is used to configure the delay time (in seconds) settings for backup, restoral, Talkwire and Alarm commands.
KBU 64 User Manual 4.15.2 BACKUP Timer If BACKUP is set to AUTO, the backup timer sets the KBU’s delay period before it automatically dials the backup number, and switches the data traffic to the ISDN line: 1> SET DELAY BACKUP xx[CR] where xxx is the time in seconds (0 to 999). 4.15.
Configuration Commands 4.15.5 DISCONNECT Timer When DISCONNECT is set to MAN (default/normal) this timer is not used. However, if DISCONNECT has been set to AUTO, this defines the time your KBU 64 will wait before disconnecting the USER port (data traffic) from the ISDN line: 1> SET DELAY DISCONNECT xx[CR] where xxx is the time in seconds (0 to 999). 4.15.
KBU 64 User Manual where xxx is the time in seconds (0 to 999). A value of 0 (factory default) disables backup on detection of I/DSR going LOW on the LINK port. Note: Only Kilostream NTUs operating at 9600 bit/s and below provide an indication of line quality via the DCD control signal. Therefore, the NTU delay timer has no effect on a Kilostream link which is operating at a higher data rate.
Configuration Commands A value of 0 (factory default) disables this facility. 4.15.11 TWDATA Timer When an ISDN backup call is in operation the KBU 64 tests the leased line by using it’s Talkwire protocol. The TWDATA timer defines how long this test must be detected as running successfully, before the KBU 64 will accept that the leased line has been restored.
KBU 64 User Manual 4.15.13 DIAL Timer Defines the length of time your KBU 64 will take to redial following an unsuccessful ISDN call: 1> SET DELAY DIAL xxx[CR] where xxx is the time in seconds (0 to 999). Note This DIAL timer is only used during alternate redialling of telephone numbers, as detailed in section 4.14. 4.15.14 REDIAL Timer Defines the length of time taken by the KBU 64 between complete Alternate Re-dialling cycles: 1> SET DELAY REDIAL xxx[CR] where xxx is the time in seconds (0 to 999).
Configuration Commands 4.16 Verifying the ISDN Line The VERIFY command will initiate a test of the line using both channels; providing Talkwire is enabled for both channels (see section 7), and STORE directory location 1 has been configured to contain the telephone number of your backup line. Type: 1> VERIFY[CR] to initiate a test of both channels of your ISDN link. 4.16.
KBU 64 User Manual With FLASH set to ON, the relevant front panel LED will flash to indicate that an alarm state is being output to the ALARM port. Alternatively with FLASH set to OFF, the relevant front panel LED will be constantly lit, when indicating that an alarm state. This facility does not affect the presentation of alarms or signals on the rear panel. 4.
Configuration Commands 1> SET ADDRESS XXXXX[CR] where xxxxx is from 1 to 5 alphanumeric characters. To display the sub-address number that has been set type: 1> ADDRESS[CR] To remove the sub-address number, type: 1> SET ADDRESS[CR] 4.20 Password Protection Password Protection has been implemented in this version of software. Typing: 1> PASSWORD[CR] displays whether password protection is enabled or not (it is normally disabled.) 4.20.
KBU 64 User Manual You will now have full access to your KBU 64. If you are not successful, the response will be: Password mismatch - password disabled You must now repeat the entry process. When entry to a password protected KBU 64 is required, you simply enter the password (the command line will always prompt: Enter password: when password entry is needed for access to it).
Configuration Commands 4.20.4 Disabling Password Protection This is done by entering one or more spaces on both the first and confirmation entries to the Enter password: prompt. Password protection is then disabled. 4.20.5 Reserved Passwords ‘Version’, ‘poll’ and ‘local’ may not be used as passwords. ‘Version’ is the only command that can be issued with a password protected KBU 64 that is logged out; ‘Poll’ and ‘Local’ are reserved for management of local and remote units. 4.
KBU 64 User Manual will remove the channel MSN number. Typing: 1> NUMBER[CR] will display the MSN number which has been set. An incoming call on a line configured for MSN will be routed to that particular channel if it matches the MSN on that channel. If MSN is not set on either channel, then the call will be accepted by either channel, depending which ‘B’ channel is used.
Configuration Commands 1> SPID[CR] To clear a SPID that has been set, type: 1> SET SPID CLEAR[CR] the SPID value will then be erased. If this command is entered, a new SPID value must be entered before the KBU 64 is used again. A SPID value that has been set can of course be changed using the SET SPID command. 4.22.2 USA Switch Type The KBU 64 can be set to operate with two kinds of public switch in the USA, as each switch requires slightly different signalling.

KBU 64 User Manual 5.4 Backup to Dual Kilostream Links at Two Sites In a dual 64Kbit/s synchronous Kilostream link application, it is necessary that when a failure of the link occurs, the failure is detected and a backup is automatically initiated via the ISDN. The unit then monitors the faulty Kilostream, to which data is automatically restored once the link is functional and has been checked.

Example KBU 64 Applications The STORE directories of channel 2 of Sites B and C are not used, however the STORE directory of channel 1, in each case, should contain the corresponding telephone number of Site A’s channels. Backup will only be enabled between the times set within the backup WINDOW.
Manual Backup Commands 6. Manual Backup Commands 6.1 Introduction Manual Backup commands offer you a wider choice of applications than simply a manual initiation of an automatic backup call. Calls can be made to any telephone number on the ISDN, meaning data can be routed to any remote KBU 64 within the network. The intended ISDN automatic backup path could be called up and checked, leaving data to pass over the Kilostream link.
KBU 64 User Manual 6.2 Manually Initiated Backup to the ISDN Line You can initiate Manual backup from the appropriate command line prompt by issuing the BACKUP command. 1> BACKUP[CR] In our example backup is initiated on channel 1, using the telephone number stored in STORE directory location 1, to make a call over the ISDN. If the call is unsuccessful, alternate redialling is initiated as described in section 4.14. When the call has been answered, USER 1 port is connected to the ISDN line.
Manual Backup Commands NOTE: If the remote KBU 64 that you are calling has ANSWER set to CLID, it will reject your call, unless your telephone number is one of those held in the remote KBU’s CLID directory. Alternatively, a telephone number held within a specified STORE directory location can be used as the number to dial. For example, typing: 1> DIAL Nn[CR] where n is the STORE directory location of the required telephone number.
KBU 64 User Manual 6.5 Connecting the USER Port to the ISDN Line Following DIAL or ANSWER commands, the CONNECT command is used to interrupt the Kilostream data path and re-direct data down the ISDN link, if the ISDN link is on-line. 1> CONNECT[CR] This command is not needed for either manual or automatic backup calls. 6.6 Disconnecting the User Port from the ISDN Line The DISCONNECT command is used to disconnect the USER port from the ISDN channel and revert data transmission to the Kilostream line.
Talkwire Operation 7.Talkwire Operation 7.1 Introduction Talkwire is the name given to the communication protocol which enables remote control and configuration of a KBU 64 from the command terminal of your local KBU 64. You can do this, either by placing a call over the ISDN network to the remote unit, or by using the Kilostream link (if data is being routed over the ISDN line). The four primary functions of Talkwire are: 1. Sending messages to the Command terminal screens of remote KBU 64s. 2.
KBU 64 User Manual 1. TALKWIRE must be set to ON at both ends of the required link. 2. Your KBU 64 is a dual channel device, serving two separate Kilostream links, each with an ISDN backup channel. Talkwire can operate over the ISDN or the Kilostream link, but can not use the same path being used to transmit user data.
Talkwire Operation ACTIVE indicates that the facility is in use (backup is in progress, or remote diagnostics are initiated). 7.3 Initiating a Talkwire Call Let us assume that TALKWIRE is set to ON for both channels of your KBU 64 and that the USER ports are connected to the Kilostream lines (for data transmission), also the CONNECT parameter is set to MAN.
KBU 64 User Manual Note that the calling line ISDN number will only be presented if the network is providing the CLI. An unsuccessful Talkwire call will be identified by a screen message of: 1: TALKWIRE TIMEOUT This is displayed after the time set within the Talkwire Delay Timer has elapsed. Talkwire continues to be operative, trying to establish the connection. If the link becomes useable at any time, for any reason, a Talkwire connection will be established at that time.
Talkwire Operation switches to the Kilostream link, and continually transmits minimal data to try to establish a link to the remote unit. When the Kilostream link is repaired or restored, Talkwire is then able to make a satisfactory connection, indicating that the data link is up and passing data.. 7.6 LOCAL Mode An active Talkwire link has certain functions which enable you to command the actions of a remote KBU 64 without having full command of the remote COMMAND port. This state is called Local Mode.
KBU 64 User Manual In this case the command line prompt is telling us that the remote command mode is active over the local KBU's channel A (1) and that we are currently at the command prompt for channel 1 on the remote KBU 64. A prompt of A2> indicates the ISDN link is on channel A(1) of the local, and you are prompting channel 2 of the remote KBU. A prompt of B1> indicates the ISDN link is on channel B (2) of the local, and you are prompting channel 1 of the remote.
Talkwire Operation The originating unit, receiving a correct Talkwire sequence, sends a CONNECT command to the remote unit, which is acknowledged by the remote unit turning Talkwire OFF, and switching data traffic to the ISDN line. The originating KBU 64 seeing Talkwire turned OFF, connects its USER port to the ISDN line, thus establishing a backup link. With the backup link established, Talkwire is inhibited over the ISDN, and the KBU 64 attempts a Talkwire connection via the Kilostream Link.
Polling Multiple KBU 64s 8.Polling Multiple KBU 64s 8.1 Introduction Polling provides you with the ability to access the COMMAND ports of a number of KBU 64s, from a single command console. Up to 4 KBU 64s can be connected to the command console via a Fivemere Port Sharer PSV4. These can be cascaded to provide support for a total of 999 KBU devices. Refer to your PSV4 User manual for details of the required connections.
KBU 64 User Manual 8.3 Configuring the KBU 64s Polling Address So that the COMMAND port of each of the polled KBU 64s can be individually addressed from the command console, each KBU 64 must be configured to have a unique polling address. To do this, from either command line prompt, type: 1> SET POLL xxxxx[CR] where xxxxx represents the unique address, in the range 00001 to 99999. This poll address should be noted, as the KBU 64 cannot be contacted without issuing the poll address.
Polling Multiple KBU 64s 8.5 Connecting to a Specific KBU 64 Within a Polled Environment Having configured the CONSOLE parameter within your KBU 64 to POLL, access to the COMMAND port can only be gained by specifying the polling address of the unit. For example, from the command console, type: 1> POLL 00001[CR] or, where leading zeros exist as above, just: 1> POLL 1[CR] to connect you to the COMMAND port of the KBU 64 whose polling address is set as 00001.
