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.
2.4 SIC-1TPRI/SIC-1T1-F
2.4.1 Introduction
1-port channelized T1/CT1/PRI compatible interface card (SIC-1TPRI) supports:
z
Transmission/Receiving and handling of T1 data streams;
z
CT1 (channel T1) access;
z
ISDN PRI function;
z
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):
z
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.
z
SIC-1T1-F does not support PRI mode.
