A switchboard device and methods of operation of same are disclosed. Embodiments of the invention may provide a flexible means of interconnecting wideband and narrowband communications interfaces, where wideband communications interfaces may transfer low-band data and high-band data, and narrowband communication interfaces may transfer low-band data. Low-band data may be combined and sent to a narrowband communications interface or a wideband communications interface. High-band data may be combined and sent to a wideband communications interface. The low-band data may represent audio signals below a predetermined frequency, while the high-band data may represent audio signals above the predetermined frequency. The predetermined frequency may be, for example, approximately 4 kHz. The spectral mask of the low-band data may meet the spectral mask of G.712. Methods of operating embodiments of the present invention are included. An additional aspect of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing.
