Hi everybody,

I have the same exact problem as stated in .5 and I want to know if there is 
any conclusion. One of our customers have two DEWBR-N (rev.=A01), one with 
IOS 10.3 and the other with IOS 9.14, between them they have two RAD ASM-40
modems connected with V.35 cables to the BR90T2s and 4 pair twisted cable in 
the connection modem-to-modem.

Everything works O.K. up to T1 speed, but at E1 (2048 Kbps) speed the 
interface goes DOWN. We tried doing local loopback and the results were the 
same, O.K. up to T1, Interface DOWN for E1.

I will appreciate if someone could help me in this issue or just share the 
answer given in the escalation process mentioned in .12.

Thanks in advance,

622.15Known problems with RAD ModemsFOUNDR::SHEEHANTue Apr 15 1997 15:0515
 Hi Gian Carlo,

 There have been multiple entries in the Common Brouters
 notes confrerence relating to RAD ASM-40 Short Range modems
 at 2048kbps EI speeds. See notes 580 and 657 in the notes
 conference IROC::COMMON_BROUTERS  See 580.7 for DECbrouter
 mention of RAD modem not working.

 I'l check if there is a list of supported Sync modems/CSU's
 which have been qualified with the DECbrouter at E1 Speed.

622.16maybe not only RAD problemNNTPD::"casadei@mail.dec.com"Gian Carlo CasadeiWed Apr 16 1997 14:1220
Hi Neil,

I read the NOTES you mentioned in .-1 but why, if the problem is a Sync's
lost,
in a local loopback don't work ? And also, the same customer have another 
connection with ASM-40 at E1 but the only difference is that there they are 
using CISCOs and it works O.K. To me seems an incompatibility between RADs and

DECbrouters.
By the way, did you found the list of supported Sync modems/CSU's which have 
been qualified with the DECbrouter at E1 Speed ? That will help us in the
future,
so we could recommend only those wich are supported (are we doing things like 
MICROSOFT??? 8>( I'm sorry for the comparison !!!).

Thanks in advance for your help.
