Step 4: Check the status of LINK LED on the SIC-1EPRI/SIC-1E1-F panel: ON means
the link is connected and OFF means the link is not connected. In the latter case,
check the line.
SIC-1TPRI/SIC-1T1-F
Introduction 1-port channelized T1/CT1/PRI compatible interface card (SIC-1TPRI) 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-1TPRI and 1-port Fractional T1 interface
card (SIC-1T1-F):
■ FT1 mode of SIC-1T1-F can support only one channel bundle (the rate is n × 56
kbps, n=1-24), while the 24 channels can be grouped into multiple arbitrary
bundles by SIC-1TPRI.
■ SIC-1T1-F does not support PRI mode.
