2 Gigabit Ethernet interfaces
31 Serial interfaces
2 ISDN Basic Rate interfaces
1 terminal line
1 Channelized E1/PRI port
4 Voice FXS interfaces
1 cisco service engine(s)
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.
62720K bytes of ATA CompactFlash (Read/Write)
