Q. How to change number of ports that needs to be configured?

Ans. If wanpipe is not getting in connected first thing to do is debug wanpipe using below link:
Wanpipe Debugging
After debugging wanpipe if everything looks good then please change the framing type in the wanpipe configuration. For change in wanpipe configuration please go above explanation w.r.t. change in wanpipe configuration. In case after changing the framing type still wanpipe is not in connected state and everything w.r.t. wanpipe looks good as per wanpipe debugging link then change then change the "impedance mode" to 0 and "rx level" to "43db" in wanpipe configuration as shown below:
sdla_fe_cfg->cfg.te_cfg.high_impedance_mode = 0;
sdla_fe_cfg->cfg.te_cfg.rx_slevel = WAN_TE1_RX_SLEVEL_43_DB;
This is because in case of No tap isolation if we enable high impedance then the amplification becomes too HIGH which distorts the signal.
NOTE: By default for tapping mode high impedance is set to 1 and Rx level is set to 12DB.
