In addition, you can use the module for other purposes,such as CE1 access and the ISDN PRI function.• FIC-1E1-F/FIC-2E1-F/FIC-4E1-FThe 1-/2-/4-port fractional E1 interface module (FIC-1E1-F/FIC-2E1-F/FIC-4E1-F) differs fromthe FIC-1E1/FIC-2E1/FIC-4E1 primarily in the sense that:{ The FE1 operating mode supported by the E1-F modules allows only one n No 64 kbpsbundle to be formed on each interface, where n = 1 to 31. However, an E1 module allowsarbitrary grouping of 31 channels and multiple bundles.{ The FIC-E1-F modules do not support PRI mode.Interface specificationsTable 160 Interface specificationsItem FIC-1E1/FIC-1E1-F FIC-2E1/FIC-2E1-F FIC-4E1/FIC-4E1-FConnector DB-15 DB-15 DB-25Number ofconnectors 1 2 1Interface standard G.703, G.704Interface rate 2.048 MbpsCable type• E1 75-ohm unbalanced coaxial cable• E1 120-ohm balanced twisted-pair cable• 120-ohm 4E1 adapter cable (FIC-4E1/FIC-4E1-F)• 75-ohm 4E1 adapter cable (FIC-4E1/FIC-4E1-F)• Coaxial connector, network connector, 75-to-120-ohm adapter (with BNCconnector)Operating mode E1, CE1, ISDN PRI (only supported by the FIC-E1 modules)FE1 (only supported by the FIC-E1-F modules)
