Monitor Digium E1 Port/Span Alarm Status through SNMP

Hey Everyone,
I’m running couple Asterisk Boxes with Digium E1 Cards, Dahdi and Chan SS7.
I’ve enabled snmp support to improve monitoring and although I can pull a lot of info from Asterisk/VoIP portion from snmp, I cannot see any information regarding Dahdi or State of E1 ports/spans or individual channels.
Now, Chan_SS7 has a separate paid product to monitor SS7 stuff through SNMP and I may consider that option in future…
However at this point in time I’m interested if I can get Dahdi port/span Alarm statuses through snmp. (or maybe even more)

To be more precise, I need to see which Span has RED/OK Alarm status.
This can be pulled by the following command in Asterisk Console.

asterisk*CLI> dahdi show status
Description                              Alarms  IRQ    bpviol CRC4   Fra Codi Options  LBO
T4XXP (PCI) Card 0 Span 1                OK      0      0      0      CCS HDB3          0 db (CSU)/0-133 feet (DSX-1)
T4XXP (PCI) Card 0 Span 2                RED     0      0      0      CCS HDB3          0 db (CSU)/0-133 feet (DSX-1)
T4XXP (PCI) Card 0 Span 3                RED     0      0      0      CCS HDB3          0 db (CSU)/0-133 feet (DSX-1)
T4XXP (PCI) Card 0 Span 4                RED     0      0      0      CCS HDB3          0 db (CSU)/0-133 feet (DSX-1)

If anyone has a clue how to get this info (or a comparable information) through snmp please point me into a right direction.

Another alternative would be to use libss7 instead of chan_ss7, IF it has SNMP support.
However, I could not find any information on this matter… so if you do know that libss7 provides ss7 link/channel status information through SNMP please let me know.

I would be thankful for any input you may have in this matter.
Thanks in advance.
