Introduction

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.

LUCENT TECHNOLOGIES IS NOT RESPONSIBLE FOR MAKING THESE CONFIGURATIONS WORK.

Table 1-1shows the specifications of the DEFINITY Extender 1100 System.

NOTE:

Specifications are subject to change without notice as technological or manufacturing changes warrant.
