Malden Analogue (DSLA)
The DSLA is a high-quality 2, 4 or 6 channel analogue hardware device designed by Malden with an optimal interface for voice-band test.Description
Each channel offers three modes of connection to connect reliably to any type of analogue system you may need to test. Connect to the handset port on a VoIP phone, the 2-wire line connection to a PBX or PSTN and to the hands-free port of a mobile phone or a sound card in a PC.
Features
Front Panel Interfaces
- Two, four or six telephone line ports (600 Ω or complex impedance) on RJ11. Output level limited to +6dBm. DTMF or Pulse dialling
- Two, four or six balanced and floating handset inputs (10kΩ) and outputs (25 Ω) on RJ22. Output level attenuated by 28dB. Network isolated.
- Two balanced and floating inputs (600 ± 0.1 Ω or 1 MΩ) and outputs (600 ± 0.1 Ω) on 4mm sockets (2 Channel DSLA only)
- Monitor output(s) with switching/mixing of input and output of each channel pair
- 4 or 6 x 3.5mm jacks for control purposes (4, 6 Channel DSLA)
Back Panel Interfaces
- 10/100 Mbps Ethernet, IPv4 for each channel pair
- RS232 9-way serial for each channel pair
