The TM2LP-module board S30810-Q2159-X150 (Universal analogue trunk module) is a networking-module with eight analogue interfaces, which operate according to the loop-process.

• Outgoing traffic: direct
• Incoming traffic: via attendant console (HKZ), direct dialing (DID)
• Two-way traffic
• Telecommunication signaling process: IWV, MFV and MFC-R2 (configuration per set)

Specifications:

• Same functionality as the previous generation module board
• 8 Ports per module board
• Fine protection on the module board
• SIPAC-back plane plug
• 50 Hz charging meter / message accounting

Compatible to the following systems:

• Hicom 300E starting at the sofware version EV2.0
• Hicom 300H
• HiPath 3800
• HiPath 4000
• OpenScape 4000

The TMOM2 (Trunk Module Outgoing Multipurpose) module contains two adapter sets for connecting special equipment (peripheral devices).
In certain circumstances, it can be used as an outgoing circuit in order to facilitate tie-line connections.
The operating mode is set by AMO TSCSU. The two circuits on the module can be operated differently, independently of each other.

The TMOM2 module enables the following special equipment to be connected to the Hicom system:

• Paging / code calling equipment
• Dictation equipment (DE)
• Entrance telephone
• Public address system (PA)
• Outgoing loop signaling equipment
• Night watchman''''s register system
• Recorded announcement equipment.

The universal analog trunk module (TM2LP) board offers a twin-wire interface to analog public trunks and operates using the loop procedure.

• Outgoing traffic: direct
• Incoming traffic: by means of attendant console (MSI), direct inward dialing (DID)
• Both way traffic
• Dial Signalling method: DP, DTMF and MFC-R2 (method configurable per circuit)

The TM2LP board has access to four highways, two of which are supported by loadware. The board includes the necessary circuitry to support loop closure or monitoring for call detection (loop or reversal polarity) and call charge detection for up to 8 ports.

The analog speech paths are converted to the internal HiPath digital display (and vice-versa) using an A/D Converter and analog elements implemented in accordance with country-specific transmission technology providing a large range of interface matching for each standard of countries.

A uP MC68340 with 512 KB Flash EPROM and 256 KB SRAM, together with two C509-L as pre processors are used for interpreting system commands and processing line signals changing the old 8051 platform as CPU to the 16-bit data bus and 24-bit adress bus microprocessor platform.

The charge frequencies to be detected are selected using DIP switches.

The following essential properties characterize the new TM2LP board:

• Same functionality as the discontinued board in each case
• Eight ports per board
• Protection on the board
• SIPAC backplane connector
• Two LEDs
