描述 Description

The MT8930C Subscriber Network Interface Circuit (SNIC) implements the ETSI ETS 300-012, CCITT I.430 and ANSI T1.605 Recommendations for the ISDN S and T reference points. Providing point-to point and point-to-multipoint digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE).
