This interface is also known as an S/T interface. There are three ISDN BRI S/T WICs: Note You can distinguish between WIC36 and WIC models of an ISDN BRI WIC by the location and labeling of the LEDs and by the number and location of cutouts in the faceplate. • 1-port ISDN BRI WIC with S/T interface (WIC36-1B-S/T) (see Figure 44) • 1-port ISDN BRI WIC with S/T interface (WIC-1B-S/T) (see Figure 45) • 1-port ISDN BRI WIC with S/T interface, version 3 (WIC-1B-S/T-V3) (see Figure 46) Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 1-port ISDN BRI WIC with S/T interface, version 3 (WIC-1B-S/T-V3) only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.
