MF Trunk Signaling ICs
MF signaling ICs, available in a variety of formats, eliminate the
need for additional software required to implement MF signaling
protocols in trunk circuits. Used in MF trunk signaling
applications, these products include a family of PCM digital MF
tranceivers in a variety of formats. Signaling formats include R1
(A Law and µ Law), and R2 Specification.
