[cisco-nas] GSM/V.110 connection speed

[Daniel Ruch]

Hi,

 

We have 3640 routers with Mica digital modems (6-DM or 12-DM) for async. and
GSM/V.110 dial-in. The GSM (V.110) dial-in works fine, the router reporting
connection speeds of 28800/28800 or 38400/38400. But the data troughput with
ftp or file-sharing is very poor (e.g. only 1000 - 1500 bit/s). Normal ISDN
or V.34 connections to the same routers are ok, no problem with the data
troughput.  GSM/HSCSD connection with the same moblies to an ISP are also
ok.

 

We use Cisco 3640 with IOS 12.2(23) and Mica Portware 2.9.5.0

 

Does anyone have any experiance or idea?

 

Thank's a lot,

 

Daniel Ruch
