CODEC-ISO-BW shows the USB Isochronous bandwidth reserved on the USB controller to serve the CTIP. The audio codec always reserves the bandwidth of TWO CTIP even if one is disabled.

This is what appears in the CTIR Connection (from PBX port group to GSM gateway):

15.4.2. Statistics of CTI GSM/UMTS/LTE ports

This command can help to understand what is happening, in case of troubles:

d s ctip / d se ctip

Shows the statistics of all the CTI ports such as the number of calls (successful and unsuccessful), the duration of the calls, the number of connection/disconnection of the GSM/UMTS device, the number of connection/disconnection of the audio-codec device and the number of CELL packets exchanged.

d s ctip:<CTIP_number> / d se ctip:<CTIP_number>

Shows the statistics of a single CTI port.
