Introduction
A 1/2-port ISDN BRI S/T interface module (SIC-1BS/SIC-2BS) mainly transmits and processes ISDN
BRI S/T traffic flows. A 1/2-port ISDN BRI U interface module (SIC-1BU/SIC-2B) mainly transmits and
processes ISDN BRI U traffic flows.
Both SIC-1BS/SIC-2BS and SIC-1BU/SIC-2BU have two working modes: dial-up and leased line.
