Table 3-4 Operational Parameter Descriptions for a Loopback Test Call
Parameter Description
Parameter #1 Connect Protocol: LAP-M
LAP-M is the connection protocol.
Parameter #6 Total Retrains: 0
The modem has no retrain counts.
Parameter #8 Connected Standard: V.34+
The modem connects at V.34.
Parameter #9 TX,RX Bit Rate: 33600, 33600
The receive and transmit bit rate is 33600 bps, which is the fastest
possible V.34 speed. You will never attain V.90 with this test.
MICA-to-MICA calls default to V.34 modulation. V.90 requires
one analog modem.
Parameter #11 TX,RX Symbol Rate: 3429, 3429
The transmit and receive symbol rate is 3429. To achieve 33600
bps, you must have a 3429 Hz passband.
Parameter #21 Signal Noise Ratio: 41 dB
The signal to noise ratio is 41 dB.
