The programmable Signaling and CODEC Filter with 4 channels, PEB 2465, implements 4 t/r (a/b) interfaces to link analog voice terminals to PBX subscriber lines or analog PBX trunk lines to public switches. An integrated Digital Signal Processor handles all the algorithms necessary, e.g. transhybrid-loss adaption, gain, frequency response, impedance matching. The IOM-2 Interface handles digital voice transmission, SICOFI-4 feature control and transparent access to the SICOFI-4 command and indication pins. To program the filters, precalculated sets of coefficients are downloaded from the system to the on-chip coefficient RAM. Thus it is possible to use the same line card in different countries.
The SICOFI-4 is a CMOS device offered in a P-MQFP-64 package.

• Eight full duplex 2B+D UPN interface transceivers, each equipped with the following functions:
Conversion from/to binary to/from pseudo-ternary code
Receive timing recovery
Activation/deactivation procedures, triggered by primitives received over the IOM interface or by INFO received from the line (e.g. detection of INFO 1)
Execution of test loops
Analog line transceiver for up to 16 dB line attenuation
UPN interface functions compatible to PEB 2095, IBC, and PEB 20950, ISAC-P (except for looplength)
UPN interface fully compatible to PSB 2196, ISAC-P TE, and PSB 2197, SmartLink-P.
• IOM-2 interface
• Support for JTAG boundary scan test
• 1m CMOS technology with low power consumption
• P-MQFP-44 package
Note: UPN refers to a version of the standard interface UP0 (according to ZVEI standard) with a reduced loop length (up to 1.3 km).
