Product Summary
The ZL50019QC is a maximum 2,048 x 2,048 channel non-blocking digital Time Division Multiplex (TDM) switch. The ZL50019QC has thirty-two input streams (STi0 - 31) and thirty-two output streams (STio0 - 31). The ZL50019QC can switch 64 kbps and Nx64 kbps TDM channels from any input stream to any output stream. Applications are (1)PBX and IP-PBX; (2)Small and medium digital switching platforms; (3)Remote access servers and concentrators; (4)Wireless base stations and controllers; (5)Multi service access platforms; (6)Digital Loop Carriers; (7)Computer Telephony Integration.
