VOICE/DATA TRANSMISSION TEST SET
Information
The AM5XT and AM5eXT are microprocessor based test
instruments used to
measure transmission impairments on 2- and 4-wire telephone
lines. The AM5XT
measures transmission impairments in accordance with IEEE
Standard 743-1984
(Bell Standard 41009). The AM5eXT complies with CCITT
recommendations for
export.
The instrument also contains a separate full function signal
Generator able to
generate the test tones normally used with the tests.
The instrument contains 4 impedance selections per line,
separate DC hold
circuits, pulse, MF, and DTMF signaling, built-in speaker
monitor and talk
microphone. Optional features include RS232 remote control
port, batteries for
cordless portable operation, and rack mounting kit for
permanent installations.
