I'm just experimenting with dynamic spans using TDMoE, which looks ideal for clustering Asterisk boxes with low latency (i.e. 1ms for TDMoE compared with 20ms for IAX).
When using normal E1s and T1s, I've always used ISDN signalling: either EuroISDN or NI2. So naturally I tried that over the TDMoE. I've found that I get a lot of HDLC errors and the D-channel is up and down like a yoyo. I'm wondering if perhaps HDLC signalling is too intolerant of the occasional lost packet and whether one of the other signalling types would be better. I don't understand the other methods, so I would be grateful for any advice from those who have used TDMoE successfully. On a -dev note, I see in ztdynamic.c that there is a sequence number sent in each TDM frame, but that on the receive side this is never checked for missing packets. .rxcnt in struct zt_dynamic is currently unused. I'm going to put a check in there and a printk for unexpected sequence numbers.
