DEFINITY Hardware
TN2402
The TN2402 processor platform runs at 25 MHz and integrates many functions of the TN790 processor and the TN777B NETCON circuit packs onto a single circuit pack. These functions include a 32-bit RISC CPU complex and a maintenance processor complex providing serial communications and maintenance functions. In addition, the TN2402 terminates ISDN LAPD signaling over the DEFINITY TDM bus from PRI and BRI trunk circuit packs.
The RISC CPU complex provides 4 to 32 MBytes of Flash PROM. The DRAM is provided via 1 SIMM. The TN2402 contains 16 MBytes of DRAM. The flash is not interleaved.
The TN2402 processor does not provide X.25 communications, nor does it provide a duplication option. The TN2402 does not contain an on-board modem. Instead, an external modem must be connected to the RS-232E port previously used for the internal modem.
The TN2402 is required for the csi model to save translations to the new 5-volt ATA flash memory card.
