+The Gb Implementation supports two different dialects: + +* `classic` dialect, which implements a non-standard dialect from the days + where Frame Relay was the default and no IP transport had yet been + specified by 3GPP. +* `ip-sns` dialect, which implements the 3GPP standard for NS-over-IP, + including the IP-SNS protocol. + +In case of doubt, and assuming you are directly interfacing to a +modern 3rd party SGSN, use the `ip-sns` dialect. + +Selection of the dialect is done using the `gb-dialect` VTY option at the `pcu` node. + [[pcu_sock_iface]] ==== `pcu_sock` Interface to OsmoBTS/OsmoBSC
