Description
The QFXSA plug-in card is designed for the Loop-AM3440. It allows voice frequency interfaces to be multiplexed as a 64 kbps DS0 signal onto a digital network. QFXSA provides connections to four telephones and it also provides user programmable A-law or mu-law coding. Most popular signaling conventions are supported, including PLAR (Private Line Automatic Ring down). The QFXSA supports signaling tests, including ring test, battery reverse test, channel swap, metering pulse test, and tip open test. Moreover, it supports status monitoring: line, signaling bit, and jump setting.
NOTE: The QFXSA card has to work with AM3440 controller firmware v8.38.01 or up to support below new functions:
(a) Firmware upgrade
(b) FPGA reset
(c) 0.1dB step gain adjustment
(d) Signaling bits programmable
(e) Diagnostic
(f) Signaling tests
(g) Status monitoring
