Description
The MT8930B Subscriber Network Interface Circuit (SNIC) implements the CCITT I.430 and ANSI T1.605 Recommendations for the ISDN S and T reference points. Providing point-to-point and pointto-multipoint digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE).
