MG-IP TDM Over IP Gateway Reference Manual

LED Interface
Interface activity and system status can be monitored using the LED interfaces.
MG-IP Configuration
The following section provides an overview of MG-IP configuration. There are a number of ways to
define or modify the unit configuration:
The Command Line Interface (CLI) is accessible using the UARTs or via Telnet over either
the LAN or WAN interface. The CLI can modify the parameters in the module configuration
database.
CLI script files – CLI commands grouped into a CLI script file, a text file edited and located
offline on the user’s PC. The script file is aumatically copied and processed via TFTP (see
CLI Script Files section)
SNMP – standard SNMP V2 is used for Get/Set and Trap operations (see SNMP Support
section)
TLV files – TLV files comply with the CableLabs standard and are binary files (type, length,
value) containing SNMP commands. TLV files are located remotely, copied via the TFTP
protocol and activated on MG-IP startup (see TLV Files section).
Pseudowire Sessions
The pseudowire between two MG-IP units is defined with a TDM over packet session. A session
defines the source TDM port, the format of the pseudowire packet, the maximum jitter, the header
format, and the address of the target MG-IP. The target MG-IP requires a corresponding session
definition.
Configuration Database
MG-IP units are configured using a configuration database that is stored in on-board Flash memory.
Many database parameter changes take effect only when a modified database is saved as the new
startup database and the module is restarted. Session definitions are an exception to this. After
changing the parameters of a session and saving them, the session can be disabled and then re-enabled.
The session will resume using the new parameters.
Many port configuration parameters can also be changed without requiring a module reset. The
following is a list of the configurable parameters contained in the configuration database:
WAN
Interface IP mode (Static, DHCP or none)
Interface IP and subnet mask
Auto-negotiation enable/disable
Auto-negotiation advertising values
MII Clock source (DTE, DCE)
Flow control on/off
Bandwidth limit (0 to 100 Mbps or unlimited)
