The four-wire interface provides compatibility with existing standard station range from STENTOFON with the exception of TouchLine display stations produced earlier than March 1995. These stations are no longer compatible due to reduction on the display signal output from the exchange. TouchLine display stations produced after March 1995 are labeled version 1.1 and are fully compatible with the AlphaCom exchange.

ASLT Subscriber Line Board (1009101010)

The ASLT line board is used for connection of analog intercom stations to the AlphaCom server.

Highlights

  • Each board provides six 4-wire subscriber connections
  • 6 RCO remote control outputs (software configurable activation)
  • 1 voice-switched conversation per board
  • When using handset or full duplex conference unit at both ends, the system is non-blocking within each module
  • All subscriber connections suitable for display stations
  • Line monitoring
  • Software-controlled output volume control
  • Hot plug-in/plug-out
  • Red/green/amber LED indicates system status


Installation in AlphaCom XE20/XE26

OBS icon
  • Turn power off before inserting or removing boards
  • Alternatively use the Hot-plug cable to insert/remove boards


  • In the AlphaCom XE26 the ASLT board can be placed in any board position 1-23.
    • Board position 1: Physical numbers 1 to 6
    • Board position 2: Physical numbers 7 to 12
    • !
    • !
    • Board position 23: Physical numbers 133 to 138
  • In the AlphaCom XE20 the ASLT board can be placed in any board position 1 and 8-23.
    • Board position 1: Physical numbers 1 to 6
    • Board position 8: Physical numbers 43 to 48
    • !
    • !
    • Board position 23: Physical numbers 133 to 138
OBS icon Board position 2 to 7 (physical numbers 7 to 42) does not exist in the AlphaCom XE20!



There are three different subscriber connection methods available:

Station and RCO connection to ASLT in AlphaCom XE20 and XE26



Installation in AlphaCom XE7

  • In the AlphaCom XE7 the ASLT board can be placed in any board position 1-6.
    • Bord position 1: Physical numbers 1 to 6
    • Bord position 2: Physical numbers 7 to 12
    • !
    • !
    • Bord position 6: Physical numbers 31 to 36
OBS icon

Turn power off before inserting or removing boards


Stations are connected to the AlphaCom XE7 by means of pluggable screw terminals on the backplane.

Station, program and RCO connection to ASLT in AlphaCom XE7


There are 12 RCO outputs available on pinheaders on the backplane. RCO 1-6 are controlled by the ASLT board in position 1, and RCO 7-12 are controlled by the ASLT board in position 2.

Note icon Physical numbers 5 and 6 are by default used as inputs for Audio Program distribution, but can alternatively be used for intercom stations. See related article: Physical number 5 and 6 (AlphaCom E7)


Cabling

The cabling from the AlphaCom server to the intercom station is star wiring principle. Use twisted pair cable. Two pairs of wires are required to each station. The maximum distance depends on the cable diameter:

  • 0.5 mm wires (AWG24): 1.4 km
  • 0.6 mm wires (AWG22): 2.0 km
  • 0.9 mm wires (AWG19): 4.0 km

The four wires are called a-,b-, c- and d-wires. a-b-wires are "transmit" and cd-wires are "receive".

Note icon a- and b-wire must be in one pair, and c- and d-wire in another pair


Two pairs of wires to each station



Voltage readings

For troubleshooting it might be useful to check the voltage on the lines with a voltmeter.

Voltage readings on the intercom line



Typical voltages across a- and b-wire:

  • Open line (no station connected): 32V
  • Display station connected: 24-27V
  • Non-display station connected: 29-30V

Typical voltages across c- and d-wire:

  • Open line, or station connected in Open mode: -21V
  • Station connected in Private mode: -19V
  • Station in conversation: +9 to +12V
