Hi, ;First of all, I'm newbie in this field, so please forgive my unprofessional explanation. I'm trying to connect to a mobile operator with chan_ss7 using sangoma card. the telecom regulator initiated an SPC code for us Now, the operator's engineer asked me for the following parameters: OPC , Link type , TS , SLC. but I don't know what should I provide to him. I think the OPC similar to our SPC, And the Link type is 64k, But for TS and SLC, I don't know what to say. I appreciate and applaud your help and concern. Thank you all.
