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.

Programming Ring-Master CB901

Use a terminal emulating program such as ProCom plus or Hyperterminal. See section 4.2 for detailed procedure.

Purpose of programming

• Set the data of the serial port used for ETP communication with AlphaCom E
• Set the data of the serial port used for remote dialing from AlphaCom E (PC port) and status output to AlphaCom E
• Program the feature code for the access to the numbers in the AlphaCom E
  If the feature code is one digit ‘F’, then the call number in AlphaCom E will be ‘F A A A’. ‘AAA’ represent any digit
• Identify the 6 hex positions where the NFE1545 audio interface board is connected. This is fixed to F8-FD.
• Identify the 2 hex positions (call numbers) that will be used for privacy test of the RM stations (ETP and SIO).

A modification must be carried out on the subscriber board in order to link two and two subscriber positions together. Se section 6.2

• Each modified subscriber board will offer 4 privacy links.
• Each CB901 stage must have one modified subscriber board for privacy test of the stations within the stage.

Programming AlphaComE

Use the STENTOFON AlphaPro and AlphaWeb PC programs to perform programming. See section 4.3 for detailed programming procedure.

Purpose of programming

• Identify the CB901 stage(s) where the NFE1545 audio interface board(s) is(are) installed
• Program the 6 positions used by the AGA board(s)
• Specify optional station and system functions related to CB901

• Normal station
• Privacy test
• Call request and corresponding parameters
