122FIC-8T1/FIC-8T1-FIntroduction• FIC-8T1The 8-port channelized CT1/PRI interface module (FIC-8T1) transmits, receives, andprocesses eight channels of T1 data traffic. In addition, you can use the module for otherpurposes, such as CT1 access and the ISDN PRI function.• FIC-8T1-FThe 8-port fractional T1 interface module (FIC-8T1-F) is different from the FIC-8T1 module inthe sense that:{ The FT1 operating mode supported by the FIC-8T1-F module allows only one n No 64 kbpsor n No 56 kbps bundle to be formed on each interface, where n = 1 to 24. However, theFIC-8T1 module allows arbitrary grouping of 24 channels and therefore multiple bundles.{ The FIC-8T1-F module does not support PRI mode.NOTE:For a FIC-8T1 module, the system automatically creates a serial interface for each timeslot bundleformed on a controller T1 interface.Interface specificationsTable 166 Interface specificationsItem DescriptionConnector 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 8T1 conversion cable (100-ohm straight-through shielded network cable)Operating mode • CT1, ISDN PRI (only supported by the FIC-8T1)• FT1 (only supported by the FIC-8T1-F)Supported service• Backup• Terminal access service• ISDN PRI (supported by the FIC-8T1)Interface LEDsFIC-8T1 and FIC-8T1-F panels look the same.
