Refurbished
S30810-Q2041-X
The SLMA-module board S30810-Q2041-X (Station Line Module Analogue) is the essential link between analogue-users and the Hicom 300/300E system.
The module board includes interfaces for 16 analogue subscriber lines. Each interface contains the required supply-, call-, and indications- circuit.
Specifications:
- requires external call-generators
- Operating range 2 x 750 Ohm.
- Call voltage 65V or 85V 25Hz or 50Hz
Compatible witht he following systems:
- Hicom 300
- Hicom 300E
- Hicom 300H
The SLMA board (Station Line Module Analog) is the interface between the analog stations and the Hicom system.
One board contains the trunk for 16 station lines. Each of these trunks contains the required feed, ringing and indication circuitry.
The front panel of the board contains an LED, which lights whenever a circuit is busy.
The SLMA requires an external ring generator which provides the necessary ring voltage and power. Each group of three LTUs has its own ring generator. A ring is applied on the SLMA using a relay on the b-wire. The ring cadence is controlled by the SLMA loading procedure.
Ringing voltage: nominal voltage 65 V or 85 V (against ground)
Frequency: 25 Hz or 50 Hz
The operating range is 2 x 750. This range may be reduced by using pushbutton telephones.
An NLT amplifier and an additional feeding device may be connected to increase the range. The additional feeding device must provide a current limiter of approximately 40 mA and must be looped into the a-wire. Installation should be performed at the terminal.
In the case of faults on the station line, feeding is deactivated via a command to avoid excessive power consumption (I max = 2 mA).
For the SLMA with SICOFI, the country-specific settings must be performed with the SCSU AMO, parameter COFIDX.
