Introduction
Issue 1 June 1998 1-7
Connecting at rates greater than 19,200 over a lesser quality line
will cause a high bit error rate which could result in breakups in the
audio. A 19,200 connect rate is more than adequate to sustain
proper audio quality and can be sustained on most line conditions.
Any connect rate greater than 19,200 improves data performance
through the RS-232D port of the DEFINITY Extender 1100/1101
Systems, but has no impact on voice quality. If you are not using
the DEFINITY Extender 1100/1101 Systems for data, there is no
reason to connect higher than 19,200.
If you are still having audio breakup problems when you connect at
19,200, you can lower the connection as low as 14,400 with little or
no impact on audio quality. If you are still getting a high bit error
rate even after lowing the connect speed to 14,400, you should
contact the provider of your telephone line for support.
The DEFINITY Extender 1100/1101 Systems use a 56 Flex
modem internally. Network configurations that support 56 Flex
modems should work well. Your telephone line may not support 56
Flex modems. Although custom network configurations may work
fine it is up to the end user to verify that the configuration will work.

1100 System.
