INTERFACES USAGE Clause Samples

INTERFACES USAGE. For interfaces between the MSC and the PSTN, the MSC is capable of interfacing to the local Central Office (CO) of the PSTN in MF (Multi Frequency) in-band signaling. The actual interface will depend on the capability of the local CO at the time the System is deployed. Inter-MSC handovers require dedicated CCS/C7(CCITT) circuits between the two MSCs involved. Details on signaling must be provided by the customer. Unique requirements may cause the need for additional equipment and services.
