WAN Interface Card Specifications

The BitStorm 1900 system supports the MIU (Management Interface

Unit) WAN interface.

MIU (Management Interface Unit)

The MIU is the recommended WAN interface for the BitStorm 1900. Seated next to the modem cards, the MIU processes Ethernet traffic and manages modems. The MIU provides powerful management capabilities including SNMP and the flexiblity of mixing and matching modem cards for varied configurations.

The primary functions of the MIU are Ethernet Pass-Thru and Modem Management/Auto-Discovery/Auto-Provisioning. When initialized, the MIU automatically discovers and auto-provisions modems, on its shelf, by writing a Shelf ID for each modem card in the shelf via an out-of- band I²C configuration channel. Thereafter, the assigned modems will only respond to commands from the associated MIU via the in-band Ethernet connection.

Modem parameters can also be set in the Add/Search modem links of the Database module in Site Manager.

The MIU communicates with the Site Manager or EMS, via TCP/IP, which extends the flexibility of remote equipment location(s) and network management. Each MIU requires only one IP address (the MIU IP address) to manage all modems within a shelf. The MIU uses the Modex Daemon protocol to communicate directly with EtherLoop CO and CPE modems.

An SNMP agent has been incorporated into the MIU which allows SNMP PC programs such as the StormTracker EMS 2.x or Castle Rock’s SNMPc to manage the MIU and EtherLoop modems. The SNMP MIBs, including MIB II RFC 1213 and the EtherLoop MIB, are listed in document 1900-A2-GK40, BitStorm 1900 IP DSLAM Supported SNMP MIBs. MIBs are available from the Paradyne website at www.paradyne.com.
