Paradyne 1900 User Manual

The BitStorm 1900 system supports the MIU (Management Interface 
Unit) WAN interface.

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 

 modem links 

of the 

 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.
