FIC-1SHL-4W 217FIC-1SHL-4WIntroduction The 1-port dual-pair G.SHDSL interface card (FIC-1SHL-4W) provides a four-wireG.SHDSL interface. It adopts TCPAM coding and provides symmetric rates up to4.624 Mbps. The transmission rate of the interface can automatically adapt to linedistances and conditions.Compared with ADSL, G.SHDSL allows farther transmission distance and thus hasa wider application scope. It is an alternative to E1/T1 line for high-speed dataservice access. However, as TCPAM uses the band starting from 0 Hz for datatransmission, G.SHDSL cannot share the same line with POTS or ISDN like whatADSL has done.The FIC-1SHL-4W has these features:■ Supporting manual G.SHDSL line activation/deactivation and easy-to-use faultlocation tools.■ Supporting G.992.1 interface standard and auto-sensing.■ Allowing you to set the dual-pair G.SHDSL interface to operate in dual-pair orsingle-pair mode.Interface AttributesInterface LEDs The following figure illustrates the FIC-1SHL-4W panel:Figure 266 FIC-1SHL-4W panelTable 161 Interface attributes of the FIC-1SHL-4WAttribute FIC-1SHL-4WConnector RJ-11Number of connectors 1Interface standard ITU-T G991.2ITU-T G994.1 handshakingInterface rate In single-pair mode, supports thesending/receiving independentsymmetric rates in the range from 192kbps to 2312 kbps in steps of 8 kbps.In dual-pair mode, supports thesending/receiving independentsymmetric rates in the range from 384kbps to 4624 kbps in steps of 16 kbps.Interface cable Tailor-made 4-wire telephone cableSupported services G.SHDSL over ordinary telephone lines
