TUPAVCO TEX-200 VDSL2 ETHERNET EXTENDER –UM V1.1
6Description of Setting
1. Symmetrical profile - Downstream and upstream rate are symmetrical.
2. Asymmetrical profile - Downstream and upstream rate are asymmetrical. Asymmetric
profile can beused for services like Video streaming or IPsurveillance services which require
high traffic flow in an uni-direction configuration.
3. GINP - Retransmission mode that provides enhanced protection against impulse noise or to
increase the efficiency of providing impulse noise protection (INP).
4. Interleaved - Interleaved mode has a slower transfer rate and increase latency in exchange
for error correction. A general line setting mode that provides common impulse noise
protection.
5. Max Data Rate Downstream/ Upstream -This parameter specifies the maximum net data
rate for the bearer channel as desired by the operator of the system. The data rate is coded
in steps of 1000 bit/s (G.997.1).
6. Target SNR Margin Downstream/ Upstream setting -This is the Noise Margin the xTU-
R/C receiver shall achieve, relative to the BER requirement for each of the downstream
bearer channels, or better, to successfully complete initialization. (G.997.1)
7. Special Profile Setting (Dip2: Off, Dip3: On, Dip4: On) is for application of near end
distance or poor environment, Target SNR Margin is set to high value of 24dB and rate limit
at 20Mbps to ensure channel stability. In addition, band 0 to 2.2MHz is disable to avoid
possible effects by low frequency. Because this item is set to 30a profile, so its train up time
is about 15sec to 20sec.
8. Profile Setting (Dip2: On, Dip3: On, Dip4: On) is standard profile Annex A 17a-eu32.
