• Two Network Interface Module (NIM) slots for these optional cards:
• 1, 2, or 4 full, fractional and channelized T1/E1 WAN NIM with integral CSU/DSU or
Primary Rate Interface (PRI) ports (RJ-48C).
• 1-port T3/E3 channelized/unchannelized WAN NIM with BNC ports. This NIM is also
available with up to 16 T1/E1 tributaries and system synchronization of two NIMs.
• High-speed serial port for up to 230 Kbps asynchronous and 8 Mbps synchronous WAN
NIM for leased and dial lines (68-pin serial) with universal connector supporting X.21, V.35,
RS422 and EIA530.
• 1- or 2-port serial Basic Rate Interface (BRI) WAN NIM for S/T (RJ-45) or U ports (RJ-49C).
• 1-port Annex A (POTS)/C or B (ISDN) ADSL WAN NIMs with RJ-11 connector with
CompactFlash card.
• 2-port T1/E1 Drop and Insert WAN NIM with RJ-45 connectors.
• 1-port Copper or Fiber Ethernet LAN or WAN NIM with an RJ-45 or MT-RJ multi-mode
interface.
• Three 10/100/1000BaseT GigabitEthernet LAN connectors and a Mini-Gigabit Interface
Converter (MGBIC) fiber-optic port capable of operating in full or half-duplex modes.
• COM (console) serial interface including modem control signals for remote debugging, or out-
of-band configuration
• 128 MBytes of 64-bit, 133 MHz SDRAM/DIMM memory, 8 MBytes of Onboard Flash RAM,
optional 16 MByte plug-in CompactFlash RAM card upgradeable to 1 GByte for firmware,
image and alarm storage.
• PCI-based, Encryption Module hardware accelerator for: encryption/decryption (3DES),
Message Digest (MD-5, SHA-1), and public key acceleration.
• Alarm detection, local and remote loopback, and loopback tests.
