The ATLB-12 board

Features

  • High capacity line card for analogue telephones supporting 12 subscribers lines
  • Supports all ACM telephone features
  • Supports hotline calling and DTMF dialing
  • Each board supports 6 programmable remote outputs
  • Includes voice switching circuits for two loudspeaking conversations
  • Board hot plug-in

Description

The ATLB-12 card is a high capacity analogue telephone line card supporting 12 subscriber lines. The subscribers have access to all STENTOFON AlphaCom telephone features.

A hot-line function is available for connection of telephones without dial buttons. When the handset is lifted, a preprogrammed number is dialed. This can be a call to another subscriber or activation of a function in the exchange. The board provides 6 configurable remote control outputs for interfacing of external equipment such as strobe lights, PA control signals and more.

The card can be inserted in position 1-6 in the AlphaCom XE7 exchange, and position 1-23 in the AlphaCom XE20 and XE26 exchanges. In AlphaCom XE20 and XE26 exchanges, the board can be plugged in or out while the exchange is running using the board hot-swap function.

Connection material

Physical ports

The ATLB-12 provides 12 telephone lines. The 6 first telephone lines get the physical number according to the physical slot the ATLB-12 is but into. The 6 last telephone lines have an offset of 276 to 6 first physical numbers.

Example:

  • ATLB-12 installed in slot 1 is using physical numbers 1-6 and 277-282.
  • ATLB-12 installed in slot 2 is using physical numbers 7-12 and 283-288.
  • ATLB-12 installed in slot 3 is using physical numbers 13-18 and 289-294.
  • Etc.

Switches

The 3 DIP switches located on the ATLB-12 card are not relevant for the board’s performance since they are not implemented for use yet. They are placed on the board for future use only.

Additional notes

  • Minimum software requirement: AMC 10.60
  • Line Monitoring: The ATLB-12 must be equipped with special software (05.51 or later) in order to support line monitoring. As the ATLB-12 software cannot be updated in the field, this must be done at the factory before the board is shipped. Please contact alphasupport@zenitel.com if line monitoring is required. Note that when using ATLB-12 with line monitoring, there can be maximum 15 x ATLB-12 board in one AlphaCom XE20 or XE26 module. In addition there can be 2 x ASLT and 1 x AGA board. For the line monitoring to work, the line must be terminated with an 8k2 resistor.
