RingMaster CB901

SYSTEM BUILD-UP

General Description

An existing Ring-Master CB901 system can be expanded by adding one or more STENTOFON AlphaCom E exchanges. The two systems are interconnected via data and audio links. Stations and equipment in both systems will interact as part of the same system. The AlphaCom E IP services can be accessed from the Ring-Master system.

Data
Data are transmitted via one or two serial RS232 links.

• One link (ETP, External Trunk Protocol) is used for station-tostation

calls, Group Call, Call Request and Caller ID.

• An optional link (SIO, Serial Input Output) is used for other

functions like Privacy information and Call Request camp on.

Audio
The audio interconnection between CB901 and AlphaCom E is analogue.

• There are 6 conversation channels in a 12 pair twisted cable

between each Interlink B board in CB901 and AGA board(s) in AlphaCom E.

Audio switching control (Duplex)
There is no transfer of switching control signals between the CB901 and AlphaCom E. The switching will take place individually in the Ring-Master station and in AlphaCom E.

Programming
The CB901-AlphaCom E interface features are programmed by use of:

• SVT for the CB901 part
• AlphaPro and AlphaWeb for the AlphaCom E part and the Ring-Master Daemon

Basic System Features

All internal features in both systems will remain as they are.
The following features will be included in the interface between CB901 and AlphaCom E:

• Station to station calling.

• Display information.
  Call number of calling station or station ID

• Simultaneous (global) All-Call and Group-Call.
  One global call at the time in the RM /ACE system.

• Call request and queuing from stations in CB901 to master stations(guards) in AlphaCom E.
  Calling stations will be camped on in one program distribution channel in CB901.

• Pocket paging.
  Automatic pocket paging in both systems. One individual serial ESPA 4.4.4. connection between AlphaCom E and the pager system; and CB901 and the pager system.
  The info in the pager display will identify the caller who has to be called back manually.

• Privacy.
  Stations in CB901 will be tested for privacy also when called from AlphaCom E. The subscriber board must be modified according to section 6.2

• Remote door opening.
  AlphaCom E will generate a DTMF signal when a button is pressed in the AlphaCom station during conversation with the CB901 door station. This signal will be decoded by the remote output board DP997 inside the RM door station and used to activate the magnetic lock.

Software Description

Ring-Master CB901

The ETP (External Trunk Protocol) communication software is included in revisions from TX5.7. The software in the Ring-Master system must be upgraded if the present software revision is TX5.6 or lower.

The upgrade includes changing of E-PROMs on all processor boards. It is not necessary to change the software in the DNC.

If the software revision is lower than TX5.0 (TX4.x or TX3.x) the processor board(s) must be changed.

Connector P2 must be present on the motherboard in board position 19 in order to get power to the serial links of the processor board NFE1683.

Old systems using the first processor boards NFE1515 and NFE1592 does not have connector P2 on the motherboard in position 19. The new processor board NFE1683 can then be installed in position 20 if there are long pins on the back for the PC port connections. If there are no connection pins at the back, the whole cabinet must be changed to type DP979.
Note: If the processor board is plugged into position 20 in an old rack, you must cut out a piece of the cabinet profile in order to get room for the battery RAM on the board.
Note: The same software must be installed in all nodes in a CB901 multistage system.

AlphaCom E

The software must be of revision 10.30 or higher.
This revision includes the following software routines:

• The software module (Daemon) which is linking the CB901 ETP format with the AlphaCom E main software.
• The WEB interface which is used to configure the AlphaCom for communication with CB901 (AlphaWeb)

The AlphaPro software must be of revision 10.28 or higher. This revision includes the following commands:

• Identification of CB901 stages as nodes in AlphaCom
• Identify the audio links

AlphaWeb Configuration Commands
The Ring-Master Daemon will use a number of tables to maintain the ETP function. These tables will be configurable through the AlphaWeb window.
The following tables are identified:

• Group Call
• Call Request (CAS) to stations in AlphaCom E
• Program channel for call request camp-on in CB901.
• Privacy test of stations in CB901
• RMD system parameters

AlphaWeb System Monitoring and Logging
The AlphaCom E can monitor and log real-time events. This can be viewed in the AlphaWeb.

Ring-Master Daemon System log
The Ring-Master Daemon (RMD) will report the following to the syslog server:

• RMD Up/Down
• AlphaNet Connected/Disconnected
• Serial Port Up/Down

Ring-Master Daemon System Monitoring
The Ring-Master Daemon will report the following to the syslog server:

• AGA/ETP trunks Up/Down
• AGA Trunk allocation failed (no more audio links available)
• Unknown/Erroneous commands from the Ring-Master system

Programming

Individual programming will be carried out in each system by using a locally connected data terminal (PC or laptop).
One system can not be programmed from the other system.
Number plan

• The call number in AlphaCom E must have 4 digits in order to call from CB901 to AlphaCom E. This is limited by the ETP format.
• The number of call digits in AlphaCom E is 2 - 5. Only 4-digit numbers can be reached from the RM side.
• The maximum number of call digits in CB901 is 6. All digits from 2 to 6 can be reached from both sides.

• Identify the CB901 stage(s) where the interlink NFE1545 board(s) is(are) installed
• Specify the communication via the SIO port in CB901
• Remote dialing for connection of privacy test station positions
• Remote dialing for cancelling the privacy test connection
• Remote dialing for call request camp-on to a program channel in CB901.
• Remote dialing for program channel cancelling
• Receive event for privacy time-out
• Receive event for call button press (8 digit for identification of pager call)
• Set the data of the serial port used for AlphaCom
• Program the feature code for access to the numbers in AlphaCom E. If the feature code is one digit (F), then a call to a number (AAA) in
  AlphaCom E will be F A A A
• Select the four numbers used for privacy test

Programming CB901

• Connect a PC to the D-sub in front of the RM CPU board NFE1683 via a crossed 3-wire D-sub cable.
• Define the PC as a hyperterminal, Baud rate = 9600/8/n/1
• Log in to the CB901 central by using the super-user command

hPsaB

The super-user status is needed to adjust the two test timers later on in the process.

Ring-Master Configuration Commands

The CB901 system must be configured before the ETP feature can be executed. The configuration process is carried out through a number of SVT commands. See the SVT manual for details.

• Start by un-define the line equipment positions where the ETP trunks will be connected. This is done with the SLEU command:

SLEU F8-FD

• Continue to define which line equipment positions to be allocated as ETP trunk positions. This is done with the SETP command:

SETP 1 F8 <stage no>
SETP 2 F9 <stage no>
SETP 3 FA <stage no>
SETP 4 FB <stage no>
SETP 5 FC <stage no>
SETP 6 FD <stage no>

• Define which first digit(s) to be used as ETP call number(s). This is done via the two commands, SCDU and SFC.
  In this example 7 is used as first digit in the call numbers in AlphaCom E (ETP).
• Un-define 7 as first call digit for normal calls:

SCDU 7

• Define 7 as feature code for ETP. The feature ID numbers reserved for ETP are from 81 until 89.
  In this example we will only define ETP call digit for feature ID 87:

SFC 87 7

(87 is selected just to make it easier to remember the call number 7).

The call number series starting with 7 as first digit has been programmed to be associated with the ETP trunks.

All numbers starting with 7 will now be in the AlphaCom E. The call numbers must have a total of 4 digits (7xxx).

• Define which of the Ring-Master call numbers shall be able to make ETP calls (calls into the AlphaCom E system). Use the SFA command to give access to dial feature code 7 (feature ID 87):

SFA 1000-1999 87 +

All station in the range of 1000-1999 can call in the example above.

Refer to the SVT programming manual for general configuration of the Ring-Master CB901 system.

Privacy test call numbers SIO

This position (call number) will be used by AlphaCom E to call the stations in CB901. This must be programmed with privilege no.20, ‘Remote dial receive’.

The remote dialing in CB901 via the SIO port is automatically controlled by the RM Daemon in AlphaCom E.

The disconnect event must programmed for both the SIO number C (A side, event 12) and the called number D (B side, event 64). Please see Privacy Test explanation in section RMD Privacy links and Subscriber board modification in Subscriber boards.

SPT  20 +

( 20 is ‘Remote dial receive’ )

SSE  12,64 +

• These events must now be programmed into all RM stages by the command Set Status Output:

SSO <event no.12> <stage no.> <output to PC port><stage where the PC port is used><stop>

Example

Stage 1:
SSO 12 1 C 1 U        Disconnect C (SIO)
SSO 64 1 C 1 U        Disconnect D

Stage 2:
SSO 12 2 C 2 U        Disconnect C (SIO)
SSO 64 2 C 2 U        Disconnect D

Stage N:
SSO 12 N C 2 U        Disconnect C (SIO)
SSO 64 N C 2 U        Disconnect D

These events are used to ensure complete cancellation of the audio link when a called Ring-Master station (D) presses the X button, or automatic reset at timeout.

• Program Group Call using the following commands:

SGCN:          Program the call number for each group. 

These numbers shall also be programmed into the RMD WEB interface in AlphaCom E in order to set the relation between the internal groups in CB901 and the global group numbers in AlphaCom E.

SGCM:           Program the receivers in each group in CB901.

SPT:            Privilege to manage Group Call and All Call

Adjust test timers no. 1 and 2

• First check the settings via the command LTT.
  The value should be 70 (7 seconds) for both timers:

LTT
Time id <1,-,50/*> 1,2

Time ID	Timer	Current time
1	ETP heartbeat timeout	70
2	Wait for ETP answer	70

• Use the command STT to correct the values if they are different from 70.

CB901 communication serial port

As default there is only one serial port available in each CB901 stage for communication with AlphaCom. This is port 4, which is programmed to support Pocket Paging as default

This port must be re-programmed to support the ETP.

Note: The setup procedures for a single stage CB901 and a multi stage CB901 are different

CB901 single stage

• Program port 4 to be ETP via the SD command
• Program the communication data for port 4 via the command STTY and select E for ETP.
• Specify the following:

Baud              : 9600
Bits              : 8
Parity            : N
Stop bits         : 1

CB901 Multi stage

• Use the command STTY, and select P for Pager.
• Specify the following:

Baud       : 9600
Bits       : 8
Parity     : N
Stop bits  : 1

• Use the command SD (Set Driver) to change port 4 from Pager to ETP.
• Use the command LTTY to verify that the ETP is now identified for port 4 with the data: 9600/8/N/1.

Note: The data for port 4 cannot be changed when the driver is specified for ETP. In order to modify the data you must re-define port 4 as Pager port via the command SD.

Programming in AlphaCom E

Configuration programs

The AlphaCom E configuration is partly made from AlphaPro and partly from the embedded Web browser AlphaWeb.

The configuration includes the following steps:

AlphaPro:

• Create virtual Ring-Master node(s) which defines a data link between the AlphaCom E node and the virtual Ring-Master nod (RMD)
• Create AlphaCom E <-> Ring-Master audio links
• Create RM call numbers as Global numbers
• Call Request
• Group Call
• Update the exchange

AlphaWeb:

• Insert license for the Ring-Master interface
• Configure the virtual Ring-Master node

AlphaPro configuration

AlphaPro 10 is an off-line tool used to configure AlphaCom E. All parameters can be entered without being connected to the exchange. Once all parameter are entered, AlphaPro 10 can be connected to the exchange and the parameters can be sent. AlphaPro 10 can also upload configuration information from an exchange.

See the AlphaCom E technical manual “System Management and Operation” A100K 10318 for further programming procedure.

Bold text====Connect a PC to the exchange====

Insert the HW dongle

• Insert the hardware dongle in the PC’s parallel or USB port depending on the dongle type.
• Leave the dongle in the PC during programming and transferring of data to the exchange.

Ethernet connection

AlphaCom E exchanges communicate with the AlphaPro PC over the IP network. Eth0 is the default management port unless the configuration has been changed.

When the AlphaPro communication icon is pressed, AlphaPro will prompt you for user name and password before login to the AlphaCom. See technical manual A100K 10338 for further AlphaPro description.

AlphaPro Main Menu

Besides creating and selecting networks and exchanges, the menu has a choice of sub-menus. Five of these will be used in this programming.

Exchange & System Directory & Features Stations & Users Groups Class of Service Start Communication Program

Create RM-ACE network

From the AlphaPro Main Menu:

• Press the ‘+’ button next to ‘Select Network’
• Give the network a name, i.e. “AC-RM”
• Give the first exchange a name, i.e. “AlphaCom”
• The ‘Node Number’ shall be “1”
• Be sure the ‘AlphaNet Adm. Here’ check box is ticked
• The default IP address 169.254.1.5 is used when the AlphaWeb PC is connected directly to the AlphaCom E node on the Eth0 port. If a remote PC is connected via a network for AlphaWeb programming, this address must be changed. Contact the IT administrator to get this address.

Note: Make a note of this IP address as it must be entered manually in AlphaWeb!

• Click [OK] to confirm
  The new network name will appear in the ‘Select Network’ pull-down list and the given exchange name is automatically put in the ‘Select Exchange’ pull-down list.

Create virtual Ring-Master node(s)

From the AlphaPro Main Menu:

• Press the ‘+’ button next to ‘Select Exchange’
• Type the name of the new RM node i.e. “RM Node 101”
• Type in the node no. i.e. “101”
• Select [Ringmaster Node] from the ‘Type’ list
• Leave the [Adm. Here] flag unchecked

Note: The Ring-Master node must be assigned a higher node number than the AlphaCom node. Suggested node number is 101.

In Ring-Master systems consisting of two or more stages, you need to create more Ring-Master nodes in order to have more audio lines. Each NFE1545 / AGA board connection is considered one node.

Create the second Ring-Master node in the same way as the first, but with node number 102 and so on.

Define the data- and audio link

• Select [Exchange & System] in the Main Menu
• Select [AlphaCom] in the ‘Exchange Information’ window
• Select [Net Routing]
• Select [Insert]
• Select the new ‘RM node’ and click the [Select] button
• Select [RMD link] from the ‘Primary route’ Data ACDP link
• The audio should be on node number ‘101’
• Click [OK] to save the record
• Click the [Close] button to get back to the Main Menu

Create AlphaCom / Ring-Master audio links

• Select [Exchange & System] in the Main Menu
• Select [AlphaCom] in the ‘Exchange Information’ window
• Select [Net Audio]
• Select [Insert]
• Check that Ring-Master is the destination node and click on [Select]
• Enter the AGA board physical link number and a channel number starting from ‘1’ on the first link, ‘2’ on the second link and so on
• Repeat this operation until all audio links are defined
  Example: An E7 has two AGA boards in pos. 5 and 6. The first physical link number is (4x6)+1=25 and the last link number is 36.
• Click [OK] to save the record
• Click the [Close] button to get back to the Main Menu

Tone test

The AGA audio links are by default supervised by a test tone transmitted on the line at regular intervals.

As this test is not supported when interfacing to the Ring-Master system, the test must be disabled to prevent the links from being taken out of service.

• Select [Exchange & System]
• Click on [System]
• Select [Logs and Errors]
• Check that [Enable Tone Test] is NOT checked
• Set [Audio Test Period] to 65 535 (= Test OFF)

The audio links require further configuration from the RMD configuration page in AlphaWeb.

Create Ring-Master station numbers

All station numbers in the Ring-Master system which should be accessed from the AlphaCom E must be programmed in the AlphaCom directory table (Directory & Features) with feature 083 (Global numbers) and ‘Node’ = Ring-Master node number (e.g. 101).

In the example below, the station number 1258 is defined as Global Number for AlphaNet, feature 083. The display text will be shown in the AlphaCom station when calling the RM station. This text should be coordinated with the RM systems caller ID text for that RM station.

Further configuration of the call numbers is required from the RMD configuration page in AlphaWeb.

• Click on [Directory & Features]
• Select feature 83 ‘Global Number for AlphaNet’ in the [Feature] pulldown list
• Type the RM node number (‘101’) in the [Node] field
• Type the RM call number in the [Directory Number] field
• Type in the text which will be visible in the display of the calling AC station in the [Display Text] field
• Click [OK]. The new global number will be updated in the table on the left

Repeat this procedure for each RM number to be defined in AlphaCom

AlphaCom station numbers

All station numbers in the AlphaCom E which should be accessed from the Ring-Master system must be assigned a 4-digit directory number in AlphaCom (Users & Stations). First digit must be the feature code 7 as programmed in RM.

Call Request group numbers

When the “CAS” function is wanted in the Ring-Master system, it must be converted to generate a Call Request to a group in AlphaCom E. This “group” should include one or several guard station(s) to receive call request calls from RM as well as AC stations.

The directory no. of the group used for Call Request must be 4 digits and the first digit must be feature code 7 as programmed in RM.

Since Ring-Master has 64 group-call groups numbered from 1 - 64, groups from 65 - 100 should be used in AlphaCom E for Call Request.

In the example below, the group 65 is used for call request and the directory number for this group is 7211.

• Select [Groups], then [Local Groups]
• Scroll down to group 65 and select [65]
• Click on [Change]
• Type the Call Request call number in the [Directory Number] field
• Type in the display text in the [Display Text] field
• Click on the [Members] field. This will be the guard stations (RM CAS operators)
• Select the guard stations to be included in the group from the ‘Not Member’ list, and transfer to the ‘Members’ list
• Click [OK]

Group Call numbers

In order to make Group Call in both RM and ACE simultaneously, the Global Group numbers must be specified. Follow the same routine as described for Call Request group numbers.
