Maybe you're not getting 64kbps clear. Maybe you can knock your data calls down to 56k and they'll work?<br>
<br>
(Now ... can I remember how to do that? I guess if using legacy dialer, then "dialer map ... speed 56" ... or if dialer profile, then "dialer string ... class XXX" with "map-class dialer XXX"/dialer isdn speed 56".)<br>
<br>
Wait a minute. VIC-2-2BRI? That doesn't even handle ISDN data, does it?<br>

Hey Josh.<br>
<br>
Yeah, just O CONFREQs from both sides.<br>
<br>
I do see input crc/frame errors on Se1/0:0 on the 3825, and also on Di0 on the 1841. No errors on any of the other PRI/BRI interfaces in between though.<br>
<br>
Tried swapping the VIC2-2BRI in the 3825 which didnt help, but I dont have a spare WIC-1B to test with at the moment.<br>

So just O CONFREQs on each side then? You could look at the "sh<br>
int se1/0:x"/b-channel, maybe you're getting input errors or<br>
something?<br>

Played around with this a bit more, and Ive configured up my<br>
Se1/0:15 interface with PPP et al, almost matches the<br>
Group-Async interface, so should be right.<br>
<br>
When the ISDN data call establishes (what looks to be<br>
successfully) I see both ends start TXing PPP LCP packets,<br>
which is a good sign, but neither end is receiving anything<br>
from the other side.<br>
<br>
Pitty I cant wireshark the B channels to see whats going back<br>
and forth. :-P<br>

Yeah, the DM’s are only going to terminate analog calls.<br>
As Josh says (long time, Josh!), configure the PRI (or use<br>
Legacy DDR or Dialer Profiles) and you should be good.<br>

Subject: Re: [cisco-nas] ISDN calls not making it to NM-6DM<br>
<br>
If you just want to make it work, you can configure your<br>
IP stuff on the serial1/0:15 interface and the call should<br>
terminate there. ISDN to ISDN like.<br>
<br>
Not sure how you would simulate a real analog modem type<br>
call from the 1841 side with what you have.<br>
<br>
I could be wrong though, been a while...<br>

Hi Mark, did not expect such a quick response!<br>
<br>
Indeed it is originating from the 1841 as 8890.<br>
<br>
I also re-configured the 1841 to do DoV, where the<br>
bearercap changed to 0x8090A3, and this was also seen<br>
as the incomming bearercap on the 3825.<br>
<br>
I was under the impression from my reading that the<br>
NM-xDM could also terminate ISDN data calls, or have I<br>
got that wrong?<br>
<br>
Cheers!<br>

A bearer cap of 0x8890 means the call is digital,<br>
not analog, so the call is not being passed to a<br>
modem. Your emulating network in between must be<br>
mucking with the bearer cap (check out debug on<br>
the 1841 to verify that it’s not originating at 8890).<br>

Subject: [cisco-nas] ISDN calls not making it to<br>
NM-6DM<br>
<br>
Hi everyone.<br>
<br>
Playing around with some old hardware in a lab,<br>
trying to get some ISDN calls originated from an<br>
1841 with a WIC-1B-S/T-V3 to be answered on a 3825<br>
with a NM-6D and NM-CE1T1-PRI.<br>
<br>
Heres my config:<br>
<br>
controller E1 1/0<br>
pri-group timeslots 1-6,16<br>
!<br>
interface Serial1/0:15<br>
no ip address<br>
encapsulation ppp<br>
isdn switch-type primary-net5<br>
isdn incoming-voice modem 64<br>
isdn bchan-number-order ascending<br>
!<br>
interface Group-Async0<br>
ip unnumbered Loopback0<br>
ip nat inside<br>
ip virtual-reassembly in<br>
encapsulation ppp<br>
peer default ip address pool dialup<br>
async mode interactive<br>
no keepalive<br>
ppp authentication chap callin<br>
group-range 2/0 2/5<br>
!<br>
line 2/0 2/5<br>
modem InOut<br>
autoselect ppp<br>
!<br>
<br>
And heres what I see when an ISDN call comes in:<br>
<br>
*Jan 30 23:31:24.963 UTC: ISDN Se1/0:15 Q931: RX<br>
<- SETUP pd = 8 callref = 0x0183<br>
Bearer Capability i = 0x8890<br>
Standard = CCITT<br>
Transfer Capability = Unrestricted Digital<br>
Transfer Mode = Circuit<br>
Transfer Rate = 64 kbit/s<br>
Channel ID i = 0xA98381<br>
Exclusive, Channel 1<br>
Calling Party Number i = 0x80, '0733944124'<br>
Plan:Unknown, Type:Unknown<br>
Called Party Number i = 0x80<br>
Plan:Unknown, Type:Unknown<br>
*Jan 30 23:31:24.963 UTC: ISDN Se1/0:15 Q931:<br>
Received SETUP callref = 0x8183 callID = 0x01E5<br>
switch = primary-net5 interface = User<br>
*Jan 30 23:31:24.971 UTC: %ISDN-6-CONNECT:<br>
Interface Serial1/0:0 is now connected to<br>
0733944124 N/A<br>
*Jan 30 23:31:24.971 UTC: ISDN Se1/0:15 Q931: TX<br>
-> CALL_PROC pd = 8 callref = 0x8183<br>
Channel ID i = 0xA98381<br>
Exclusive, Channel 1<br>
*Jan 30 23:31:24.971 UTC: ISDN Se1/0:15 Q931: TX<br>
-> CONNECT pd = 8 callref = 0x8183<br>
Channel ID i = 0xA98381<br>
Exclusive, Channel 1<br>
*Jan 30 23:31:24.979 UTC: ISDN Se1/0:15 Q931: RX<br>
<- CONNECT_ACK pd = 8 callref = 0x0183<br>
<br>
So as far as I can tell the call comes in and<br>
establishes fine, but even with "debug modem" and<br>
a couple of other debugs on, I dont see any<br>
activity regarding connection to a modem. When I<br>
dial in from an analogue modem it works just fine.<br>
<br>
FWIW I am using the 3825 as a PSTN simulator as<br>
well. The 1841 is connected to a VIC2-2BRI-NT/TE<br>
emulating network, and a dialpeer connects calls<br>
to a VWIC2-2MTF-E1 which is also emulating network<br>
and is connected to the NM-CE1T1-PRI.<br>
<br>
Wondering if any one can provide any pointers to<br>
help me out. Am I missing something obvious?<br>
<br>
Let me know if you require more information.<br>
<br>
Thanks<br>
Tom<br>
