Hi all,
On an Asterisk/Zaptel 1.4 system, one way to gather diagnostic info is:
~# cat /proc/zaptel/*
Span 1: ZTHFC1 "HFC-S PCI A Zaptel Driver card 0 [TE]" (MASTER) AMI/CCS
1 ZTHFC1/0/1 Clear (In use)
2 ZTHFC1/0/2 Clear (In use)
3 ZTHFC1/0/3 HDLCFCS (In use)
Span 2: ZTHFC2 "HFC-S PCI A Zaptel Driver card 1 [TE]" AMI/CCS
4 ZTHFC2/0/1 Clear
5 ZTHFC2/0/2 Clear
6 ZTHFC2/0/3 HDLCFCS
These are two HFC-S PCI A cards. But, what exactly does all of this mean?
In particular:
* Span - In telephony, what is the definition of this term?
* MASTER - How is this relevant? Only for timing purposes?
* Clear - Is this said because only B-channels use ISDN clear codes?
* HDLCFCS - Why say this about D-channels? Why not just say HDLC?
* (In use) - What does this mean and how is this state determined?
* 1 ZTHFC1/0/1 Clear (In use) - What do each of these columns specify?
Thanks,
Jaap
