Interface Table
Chapter 3 83
This field contains the maximum number of ports supported by this
specific ACC interface card.
IMAXSUBC_PORT - Maximum number of subchannels per port.
This is the maximum number of subchannels supported on each port of
this ACC interface card. The minimum value of this field is 1 (e.g.
2/8-channel cards).
IMAXSUBC_CARD - Maximum number of subchannels on card.
This field contains the number of subchannels supported by this card.
For a non-E1/T1 card, this value should be the same as the imaxports
field.
IMAXTERMS - Maximum number of terminals allowed on card.
This field contains the maximum number of terminal ZLUs that may be
configured on this card.
IFNAME - Firmware download file name
This contains the full path name of the firmware file to be downloaded
into this Mux card whenever the ZCOM subsystem is started, the Mux
card is reset, or is recovering from a powerfail or firmware failure. It is
initialized from the information supplied in the Mux statement of the
TTGEN configuration file. This field is a maximum of 256 bytes
including the null terminator byte.
IFFLDT, IFFMNM - Download file link time and module name
These two fields contain the time (since Epoch) when the download
firmware file is linked (by zlink program) and its module name. These
are set up by zlink and stored in the download file. When ZMON loads
the file to the Mux interface card, it extracts them from the file and puts
them into these two fields. The MX command in zmntr displays these
fields.
IFRUDT, IFRMNM, IFRREV - ROM update time, module name and
revision code
The ZCOM subsystem ROM contains its module name, revision code and
update time in byte locations 40~5D hex. ZMON reads these bytes from
the Mux interface card when it loads the firmware file, and stores them
in these fields. The MX command in zmntr displays these fields. The time
is translated from the ROM ASCII time stamp and stored in Epoch
format.
IFWINFO - Firmware run-time information word
