12SIC-TPRI/SIC-T1-FIntroduction1-port channelized T1/CT1/PRI compatible interface card (SIC-TPRI) supports:• Transmission/Receiving and handling of T1 data streams;• CT1 (channel T1) access;• ISDN PRI function;• Remote loopback and local loopback, facilitating the effective and flexible debugging.It is possible to use the card for multiple purposes through different configurations.Following are the differences between SIC-TPRI and 1-port Fractional T1 interface card (SIC-T1-F):• The timeslots on an interface in FT1 mode on the SIC-T1-F can be bundled to form oneinterface (namely, can be bundled into one channel, and the rate of the interface is n No 56Kbps, where n ranges from 1 to 24.); however, you may bundle timeslots of a PRI interface onthe SIC-TPRI into up to 24 channel sets.• The SIC-T1-F does not support the PRI mode.Interface specificationsTable 18 Interface specificationsItem DescriptionConnector type RJ-45Number of connectors 1Interface standard• G.703/T1.102• G.704• AT&T TR 54016• AT&T TR 62411• ANSI T1.403Interface rate 1.544 MbpsCable type T1 cable (100-ohm standard shielded network cable)Operating mode • CT1 and ISDN PRI (supported by SIC-TPRI only)• FT1 (supported by SIC-T1-F only)Supported service• Backup• Terminal access• ISDN (supported by SIC-TPRI only)
